In the trial, Gencaro was evaluated against an active comparator, the beta-blocker TOPROL-XL (metoprolol succinate), a drug indicated for the treatment of HF patients that is also prescribed, but not approved, for treating AF.&nbsp;&nbsp; Enrollment in GENETIC-AF was limited to patients that possess the specific genotype that the Company believes enhances Gencaro&#8217;s potential therapeutic effects.&nbsp;&nbsp;The planned development program of Gencaro is, in part, based on the results of the Company&#8217;s completed GENETIC-AF Phase 2B clinical trial and a prospectively designed DNA substudy of adrenergic receptor polymorphisms in the BEST trial, a previous Phase&#160;3 study of HF patients.&nbsp;&nbsp;</p>

The Company reported top-line Phase 2B trial data in February 2018. Overall, Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate; however, trends for benefit in favor of bucindolol were observed in multiple subpopulations of patients in the trial. Based on these data, the Company believes further clinical development of Gencaro is warranted. Following review of the Phase 2 GENETIC-AF trial results, as well as its alignment with previous Phase 3 pharmacogenetic substudy data from the BEST trial, the FDA stated that data from a single pivotal Phase 3 clinical trial may be sufficient to support approval of Gencaro for the treatment of AF in patients with HF. The Company, in consultation with the FDA, developed key elements of the Phase 3 clinical trial needed to support a potential New Drug Application (NDA), details of which were submitted for evaluation and confirmed via the FDA&#8217;s Special Protocol Assessment (SPA) process in February 2019.&nbsp;&nbsp;   <font style="font-size:12pt;"> </font></p>

In light of the significant uncertainties regarding clinical development timelines and costs for developing drugs such as Gencaro, the Company will need to raise additional capital to finance the Company&#8217;s future operations and any additional development of Gencaro or any other product candidates. If the Company is delayed in completing or is unable to complete additional financing and/or a strategic transaction, the Company may discontinue its development activities or operations. </p>

The Company applied the practical expedients permitted within the guidance, which allows the Company to carryforward its historical lease classification, and to apply the transition option which does not require application of the guidance to comparative periods in the year of adoption.&nbsp;&nbsp;The Company adopted ASU 2016-02 effective January 1, 2019.&nbsp;&nbsp;As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $80,000, which represents the present value of the remaining lease payments of approximately $83,000, discounted using the Company&#8217;s incremental borrowing rate of 7.5%, and (b) a right-of-use asset of approximately $60,000 which represents the lease liability of $80,000 adjusted for accrued rent of approximately $20,000. Adoption of this standard did not have a material impact on the financial statements.</p>

The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.&nbsp;&nbsp;Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of the amendments on the financial statement disclosures. Since the amendments impact only disclosure requirements, the Company does not expect the amendments to have a material impact on the financial statements.</p>

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company calculates basic earnings per share by dividing net loss by the weighted average common shares outstanding during the period. Diluted earnings per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period increased to include, if dilutive, the number of additional common shares that would have been outstanding if the potential common shares had been issued. The Company&#8217;s potentially dilutive shares include stock options, restricted stock units and warrants for common stock<font style="letter-spacing:-0.1pt;">. </font></p>

CPEC is a licensing subsidiary of Indevus Pharmaceuticals Inc. (a wholly owned subsidiary of Endo Pharmaceuticals), holding ownership rights to certain clinical trial data of Gencaro.&nbsp;&nbsp;Under the terms of its license agreement with CPEC, the Company will incur milestone and royalty obligations upon the occurrence of certain events.&nbsp;&nbsp;If the FDA grants marketing approval for Gencaro, the license agreement states that the Company will owe CPEC a milestone payment of $8.0&#160;million within six months after FDA approval. The license agreement states that a milestone payment of up to $5.0 million in the aggregate shall be paid upon regulatory marketing approval in Europe and Japan.&nbsp;&nbsp;The license agreement also states that the Company&#8217;s royalty obligation ranges from 12.5% to 25% of revenue from the related product based on achievement of specified product sales levels, including a 5% royalty that CPEC is obligated to pay under its original license agreement for Gencaro. The agreement states that the Company has the right to buy down the royalties to a range of 12.5% to 17% by making a payment to CPEC within six months of regulatory approval. </p>

Examples of these statements include, but are not limited to, statements regarding the following: potential future development plans for Gencaro, including our ability to secure sufficient financing to support our anticipated Phase 3 clinical trial of Gencaro, the likelihood that any Phase 3 clinical trial results for Gencaro to satisfy the requirements of our Special Protocol Assessment agreement, the expected features and characteristics of Gencaro, including the potential for genetic variations to predict individual patient response to Gencaro or AB171, Gencaro&#8217;s potential to treat atrial fibrillation, or AF, future treatment options for patients with AF, the potential for Gencaro to be the first genetically-targeted AF prevention treatment, statements regarding potential Phase&#160;3 development plans for Gencaro, including the timing and results thereof, the expected features and characteristics of AB171 as a potential genetically-targeted treatment for peripheral arterial disease and for heart failure, or HF, the potential timeline for development of AB171, including any Investigational New Drug, or IND, application submission related thereto, and the ability of ARCA&#8217;s financial resources to support its operations through the third quarter of 2019, the sufficiency of our current capital to reach certain of our corporate objectives, our ability to obtain additional funding when needed or enter into a strategic or other transaction, including our ability to raise sufficient capital to fund any Phase 3 clinical trials for Gencaro and our other operations, the extent to which our issued and pending patents may protect our products and technology, the potential of such product candidates to lead to the development of safe or effective therapies, our ability to enter into collaborations, our ability to maintain listing of our common stock on a national exchange, our future operating expenses, our future losses, our future expenditures, and the sufficiency of our cash resources to maintain operations.

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">We are a biopharmaceutical company applying a precision medicine approach to developing genetically-targeted therapies for cardiovascular diseases. Precision medicine refers to the tailoring of medical treatment to the individual characteristics of each patient through the ability to classify individuals into subpopulations that differ in their susceptibility to a particular disease, in the biology and/or prognosis of those diseases they may develop, or in their response to a specific treatment. Our lead product candidate, Gencaro&#8482; (bucindolol hydrochloride), is an investigational, pharmacologically unique beta-blocker and mild vasodilator that we are developing to treat atrial fibrillation, or AF, in certain patients who also have heart failure, or HF.</p>
<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Gencaro has a mechanism of action that we believe is unique in the beta-blocker drug class and is modulated by a specific genotype. We estimate this genotype is present in about 50% of North American and European general populations. We believe that Gencaro&#8217;s potential efficacy is enhanced in treating patients who have this genotype and, if Gencaro is approved by the U.S. Food and Drug Administration, or the FDA, Gencaro could potentially be a safe and effective therapy for treating AF in patients who have HF. We also believe that Gencaro, if approved, will have market exclusivity based on patents and new chemical entity status, if approved in the United States, Europe or other markets.</p>
<p style="margin-top:12pt;margin-bottom:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In February 2018, we reported the results of our Phase 2B clinical trial, known as GENETIC-AF, in which we evaluated Gencaro for the prevention of AF recurrence in patients with HF. This population included 267 HF patients with a left ventricular ejection fraction, or LVEF, that ranged from 0.12 to 0.55. GENETIC-AF compared Gencaro to TOPROL-XL (metoprolol succinate), a drug approved for the treatment of HF patients with an LVEF&lt;0.40 that is also prescribed, but not approved, for the treatment of AF. There are no approved or guideline recommended drug therapies for prevention of AF in HF patients with an LVEF &#8805; 0.40.</p>
<p style="margin-bottom:16pt;margin-top:9pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In GENETIC-AF, Gencaro was observed to have a similar treatment effect to TOPROL-XL (metoprolol succinate) in the overall population for prevention of AF recurrence. However, additional analyses prespecified in the statistical analysis plan showed statistically significant treatment effects in favor of Gencaro in the majority of the Phase 2B population (N=196; HR=0.54; p = 0.011). Gencaro also showed statistically significant treatment effects compared to TOPROL-XL for the prevention of AF recurrence in a subset of these patients with an LVEF &#8805; 0.40 (N=91; HR=0.42; p = 0.017). We plan to conduct a pivotal Phase 3 trial, known as PRECISION-AF, evaluating Gencaro in patients with mild-moderate left ventricular systolic dysfunction because of Gencaro&#8217;s observed potential treatment effect in these patients in GENETIC&#8209;AF. </p>

The study will enroll approximately 400 patients at investigative sites in the United States, Europe and Australia. Eligible patients will have LVEF &#8805; 0.40 and &#8804; 0.55, a recent AF event, and the beta-1 389 arginine homozygous genotype which we believe responds most favorably to Gencaro. The planned trial will use standard significance criteria (p &lt; 0.01 with adjustment for interim analysis) for the primary endpoint and will include an interim analysis after a portion of total patients have been enrolled. The interim analysis is designed to assess safety, validate initial study assumptions and maintain adequate statistical power for the primary endpoint. Subject to securing additional financing, we anticipate initiating PRECISION-AF in the fourth quarter of 2019. Any future development of Gencaro, including initiating any Phase 3 clinical trial, is dependent on obtaining significant additional financing, even if we enter into a strategic collaboration around the development of Gencaro.</p>

In the U.S. patient cohort of 127 patients (approximately 50% of all patients and events), a trend for benefit in favor of Gencaro over TOPROL-XL was observed (hazard ratio of 0.70, [95% confidence interval: 0.41, 1.19]). The GENETIC-AF results in the United States were consistent with what had been observed in the pharmacogenetic substudy of the BEST heart failure trial, taking into account that BEST was placebo controlled and GENETIC-AF was Gencaro versus an active comparator. However, our analysis also showed significant treatment effects in favor of Gencaro in a majority of patients in the trial, based on factors pre-specified in the statistical analysis plan.</p>
<p style="margin-bottom:12pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">We believe that the inclusion of a small number of patients in the trial (13.9% of overall population) with long-standing and heavily pretreated HF and AF led to attenuation of the treatment effect estimates for the primary endpoint of GENETIC-AF. Therefore, in accordance with procedures outlined in the Statistical Analysis Plan, post-hoc analyses were performed that excluded 37 patients with extraordinarily long durations of HF and AF (subjects who had been diagnosed with HF and/or AF for more than 12 years). In these analyses, we observed a trend for benefit in favor of Gencaro over TOPROL-XL by intermittent, clinic-based heart rhythm monitoring for the entire cohort (230 patients [N=115 for each treatment arm], hazard ratio of 0.68, [95% confidence interval: 0.45, 1.02]) and for the HFmrEF cohort (113 patients, hazard ratio of 0.61, [95% confidence interval: 0.34, 1.10]). The onset of AF relative to the development of HF was also identified in our post-hoc analyses to have a relationship to treatment effect. In these analyses, there was an attenuation of the treatment effect estimates for the primary endpoint in patients who had long-standing AF (i.e., more than 2 years) prior to developing HF. We believe this is due to differences in the underlying pathophysiology for AF patients who eventually develop HF compared to HF patients who subsequently develop AF. Therefore, a post-hoc analysis was performed in the above patient population (N=230) that excluded patients who had developed AF for more than 2 years prior to developing HF. In these analyses, a significant reduction in the GENETIC-AF primary endpoint was observed in the overall population (N=196; HR=0.54; 95% CI: 0.33, 0.87; p&#160;=&#160;0.011) and in a cohort with an LVEF &#8805; 0.40 and &#8804; 0.55 (N=91; HR=0.42; 95% CI: 0.21, 0.86; p = 0.017). Based upon our analysis of the GENETIC-AF data, we believe further clinical development of Gencaro can be successful using entry criteria to identify patients with the characteristics for disease duration and onset described above and outlined in the following table:</p>

The most frequently reported adverse events were similar in both groups and consistent with the known safety profile of the beta-blocker class of drugs. Adverse events assessed as related to study drug by the investigator occurred in 23.8% of patients in the Gencaro group and in 30.1% of patients in the TOPROL-XL group. Of note, adverse events of bradycardia were less frequently reported in the Gencaro group (3.7%) compared to patients receiving TOPROL-XL (12.0%). During the 24-week efficacy follow-up period there were three deaths (ACM) in the TOPROL-XL group and none in the Gencaro group. Three patients died in the long-term treatment extension period after receiving Gencaro for more than a year. </p>

Laboratory Corporation of America, or LabCorp, developed the genetic test, obtained an Investigational Device Exemption, or IDE, from the FDA and provided the companion diagnostic test and services to support our GENETIC&#8209;AF trial.

<p style="margin-top:6pt;margin-bottom:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">AB171 is a thiol-containing derivative of isosorbide mononitrate. Pre-clinical data from human endothelial cells indicate that compared to nitrates in clinical use, AB171 has a genotype specific enhancement of nitric oxide, or NO, release and produces less peroxynitrite, a biologically harmful product of nitrate action. AB171 also has potent anti-oxidant properties, and these effects may contribute to its favorable differentiation from other nitrates for prevention of myocardial remodeling, anti-atherosclerotic effects and the loss of effectiveness when used as a sustained therapy. We believe the unique pharmacology of AB171, coupled with targeting to genetically-identified enhanced response subpopulations, has the potential to translate to better long-term responses than currently available treatments. We have identified what we believe to be a pharmacogenetic target for AB171 we believe may enable genetically-targeted cardiovascular development programs in two cardiovascular indications: HF and peripheral arterial disease. The European Patent Office has issued to us a patent on methods of treating cardiovascular disease and conditions with a thiol-substituted isosorbide mononitrate based on genetic targeting. The European patent has been validated in ten countries: Denmark, France, Germany, Ireland, Italy, Netherlands, Spain, Sweden, Switzerland and the United Kingdom. We also have related patent applications pending in the United States Patent Office and Canadian Intellectual Property Office. </p>

R&amp;D expense in 2019 is expected to be higher than 2018, if we initiate our PRECISION&#8209;AF clinical trial.

However, our forecast of the period of time through which our financial resources will be adequate to support our current and forecasted operations could vary materially. In May 2019, we have taken efforts to reduce personnel costs, including reduction of executive management salaries. We will need to raise additional capital to fund future operations, additional development of Gencaro or any other product candidates, or complete a strategic transaction. Such financing would likely result in dilution to our existing stockholders. If we raise additional funds through the incurrence of indebtedness, the obligations related to such indebtedness would be senior to rights of holders of our capital stock and could contain covenants that would restrict our operations. The significant uncertainties surrounding the clinical development timelines and costs and the ability to raise a significant amount of capital raises substantial doubt about our ability to continue as a going concern from one year after the Company&#8217;s financial statements have been issued.&nbsp;&nbsp;</font><font style="font-style:italic;color:#000000;"> </font></p>

Our significant accounting policies are described in Note 1 of &#8220;Notes to Financial Statements&#8221; included within our 2018 Annual Report on Form 10-K filed with the SEC. Following is a discussion of the accounting policies that we believe involve the most difficult, subjective or complex judgments and estimates. </p>

This process involves identifying services that third parties have performed on our behalf and estimating the level of service performed and the associated cost incurred for these services as of the balance sheet date. Examples of estimated accrued outsourcing expenses include contract service fees, such as fees payable to contract manufacturers in connection with the production of materials related to our drug product, and service fees from clinical research organizations. We develop estimates of liabilities using our judgment based upon the facts and circumstances known at the time. </p>

The going concern basis of presentation assumes that we will continue in operation for the foreseeable future and will be able to realize our assets and discharge our liabilities and commitments in the normal course of business and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from our inability to continue as a going concern. As of March 31, 2019, our management concluded that, due to our need for additional capital and the uncertainties surrounding our ability to raise such funding, substantial doubt exists as to our ability to continue as a going concern for a period from one year after our quarterly financial statements have been issued.&nbsp;&nbsp;As of December&#160;31,&#160;2018, our management and our independent registered public accounting firm concluded that, due to our need for additional capital and the uncertainties surrounding our ability to raise such funding, substantial doubt existed as to our ability to continue as a going concern for a period from one year after our annual financial statements had been issued.&nbsp;&nbsp;We believe our cash and cash equivalents balance as of March 31, 2019 will be sufficient to fund our operations, at our projected cost structure, through the end of the third quarter of 2019. We cannot be certain that we will be able to make any sales of our common stock in any future offering to cover our future capital needs, or at all.&nbsp;&nbsp;Changing circumstances may cause us to consume capital significantly faster or slower than we currently anticipate.&nbsp;&nbsp;If we are delayed in completing or are unable to complete additional funding and/or a strategic transaction, we may discontinue our development activities or operations, but there are no assurances that these reductions would be sufficient to allow us to continue to operate as a going concern.&nbsp;&nbsp;Therefore, even if we resolve this uncertainty, our independent registered public accountants and/or management could conclude that uncertainty as to our ability to continue as a going concern could exist at a future date.</p>

However, we cannot guarantee that will be able to obtain sufficient additional funds when needed or that such funds, if available, will be obtainable on terms satisfactory to us. If we are unable to raise sufficient additional capital or complete a strategic transaction, we may be unable to continue to fund our operations, develop Gencaro or our other product candidates, or realize value from our assets and discharge our liabilities in the normal course of business. If we cannot raise sufficient funds, we may have to liquidate our assets, and might realize significantly less than the values at which they are carried on our financial statements, and stockholders may lose all or part of their investment in our common stock.</p>

Upon specific request by a clinical trial sponsor, the FDA will evaluate the protocol and respond to a sponsor&#8217;s <font style="Background-color:#FFFFFF;">questions regarding, among other things, primary efficacy endpoints, trial conduct and data analysis, within 45 days of receipt of the request. The FDA ultimately assesses whether the protocol design and planned analysis of the trial are acceptable to support regulatory approval of the product candidate with respect to the effectiveness of the indication studied. All agreements and disagreements between the FDA and the sponsor regarding a SPA must be clearly documented in a SPA letter or the minutes of a meeting between the sponsor and the FDA.</font></p>

Moreover, the FDA may revoke or alter our SPA agreement in certain circumstances. In particular, a SPA agreement is not binding on the FDA if public health concerns emerge that were unrecognized at the time of the SPA agreement, other new scientific concerns regarding product safety or efficacy arise, we fail to comply with the agreed upon trial protocols, or the relevant data, assumptions or information provided by us in our request for the SPA change or are found to be false or omit relevant facts. In addition, even after an SPA agreement is finalized, the SPA agreement may be modified, and such modification will be deemed binding on the FDA review division, except under the circumstances described above, if the FDA and the sponsor agree in writing to modify the protocol and such modification is intended to improve the study. The FDA retains significant latitude and discretion in interpreting the terms of the SPA agreement and the data and results from any study that is the subject of the SPA agreement.</font></p>

Because of the rigorous enrollment criteria, our clinical trial timelines were delayed from our original projections. We anticipate that any future Phase 3 clinical trial of Gencaro may have similar enrollment criteria, and we cannot guarantee that we will not have similar issues in any future clinical trials.</p>

The DSMB conducted a pre-specified interim analysis of study endpoints for efficacy, safety and futility. Based on the efficacy and safety data of the interim analysis, the DSMB recommended completing the Phase 2B trial with no changes to the trial design, rather than transition GENETIC-AF to a Phase 3 trial. In February&#160;2018, we announced top-line results of the Phase 2B trial, which indicated that Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate (TOPROL-XL). We have not determined if these results of GENETIC-AF, and cannot predict if the results from a future Phase 3 clinical trial, even with an SPA agreement, would allow us to obtain regulatory approval for Gencaro. </p>

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">We do not currently have sufficient staff with the requisite experience to conduct our clinical trials and therefore will rely on third parties to conduct certain aspects of any future clinical trials. We previously contracted with a CRO to conduct components of our GENETIC-AF trial and anticipate contracting with a CRO to conduct components of any future clinical trial for Gencaro or any future clinical trials for our other product candidates. As a result, we will have less control over many details and steps of any trial, the timing and completion of any trial, the required reporting of adverse events and the management of data developed through any trial than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes as well as difficulties in coordinating activities. Outside parties, such as CROs, may have staffing difficulties, may undergo changes in priorities or may become financially distressed, adversely affecting their willingness or ability to conduct our trial. We may experience unexpected cost increases that are beyond our control. Problems with the timeliness or quality of the work of a CRO may lead us to seek to terminate the relationship and use an alternative service provider. However, making any change may be costly and may delay ongoing trials, if any, and contractual restrictions may make such a change difficult or impossible. Additionally, it may be impossible to find a replacement organization that can conduct clinical trials in an acceptable manner and at an acceptable cost.&#160;&#160;</p>

These milestones may not be achieved, and the actual timing of these events can vary dramatically due to a number of factors such as delays or failures in our clinical trials, disagreements with any collaborative partners, the uncertainties inherent in the regulatory approval process and manufacturing scale-up and delays in achieving manufacturing or marketing arrangements sufficient to commercialize our products. FDA approval of Gencaro or any other product candidate, if it occurs, is expected to require years of additional clinical development, including the completion of genetic trials. There can be no assurance that we will make regulatory submissions or receive regulatory approvals as planned. If we fail to achieve one or more of these milestones as planned, our business will be materially adversely affected. </p>

This is also likely to be true in any future collaboration with third parties and we may seek additional third party collaborators for the development of Gencaro or other product candidates.

Collaborations are complex and any potential discussions may not result in a definitive agreement for many reasons. For example, whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator&#8217;s resources and expertise, the terms and conditions of the proposed collaboration, and the proposed collaborator&#8217;s evaluation of a number of factors, such as the design or results of our clinical trials, the potential market for our product candidates, the costs and complexities of manufacturing and delivering our product candidates to patients, the potential of competing products, the existence of uncertainty with respect to ownership or the coverage of our intellectual property, and industry and market conditions generally. If we were to determine that additional collaborations for our Gencaro development is necessary and were unable to enter into such collaborations on acceptable terms, we might elect to delay or scale back the development or commercialization of Gencaro in order to preserve our financial resources or to allow us adequate time to develop the required physical resources and systems and expertise ourselves. </p>

<p style="margin-top:6pt;margin-bottom:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">We anticipate that any future clinical trial of Gencaro, if any, will require a companion diagnostic test that identifies the patient&#8217;s receptor genotype. The trial would only enroll those patients with the receptor that has the potential for enhanced efficacy, the beta-1 389 Arg receptor as detected by a beta-1 389 Arg/Arg genotype. Accordingly, we anticipate that any future clinical trial for Gencaro will require the use of a third-party diagnostic service to perform the genetic testing. There has been limited experience in our industry in prospective development of companion diagnostics required to perform the required molecular profiling. We entered into an agreement with LabCorp to provide the diagnostic services of the genetic test needed to support our GENETIC-AF trial. To provide those services, LabCorp obtained from the FDA an investigational device exemption for the companion diagnostic test being used in our GENETIC-AF clinical trial. We would expect a similar agreement and approval would be necessary for any companion diagnostic used in any future clinical trials for Gencaro.</p>

Companion diagnostics require separate or coordinated regulatory approval prior to commercialization.&#160;Changes to regulatory advice could delay our development programs or delay or prevent eventual marketing approval for our product candidates that may otherwise be approvable. In July 2011, the FDA issued draft guidance that stated that if safe and effective use of a therapeutic depends on an <font style="font-style:italic;">in vitro</font> diagnostic, the FDA generally will not approve the therapeutic unless the FDA approves or clears this &#8220;<font style="font-style:italic;">in vitro</font> companion diagnostic device&#8221; at the same time that the FDA approves the therapeutic. The approval or clearance of the companion diagnostic would occur through the FDA&#8217;s Center for Devices and Radiological Health. In 2014, the FDA issued guidance on in vitro companion diagnostic devices. The guidance allows for flexibility by the FDA in the case of therapeutic products to treat serious conditions for which no alternative treatment exists and the benefits of using the companion diagnostic outweigh the risk, but it is unclear how this discretion may be applied by the agency with respect to the companion diagnostic test related to any Gencaro clinical trials. The FDA&#8217;s evolving position on the topic of companion diagnostics could affect our clinical development programs that utilize companion diagnostics. In particular, the FDA may limit our ability to use retrospective data, otherwise disagree with our approaches to trial design, biomarker qualification, clinical and analytical validity, and clinical utility, or make us repeat aspects of a trial or initiate new trials. </p>

If we, or any third parties that we engage to assist us, are unable to successfully develop companion diagnostics for our product candidates that require such diagnostics, or experience delays in doing so, the development of our product candidates may be adversely affected, our product candidates may not receive marketing approval and we may not realize the full commercial potential of any products that receive marketing approval. As a result, our business could be materially harmed. </p>
<p style="margin-bottom:0pt;margin-top:18pt;text-indent:0%;font-weight:bold;font-style:italic;font-size:10pt;font-family:Times New Roman;text-transform:none;font-variant: normal;">We will need to establish a collaborative arrangement with a third-party diagnostics services provider to obtain marketing clearance or approval of the companion genetic test. There is no guarantee that the FDA will grant timely clearance or approval of the genetic test, if at all, and failure to obtain such timely clearance or approval would adversely affect our ability to market Gencaro. </p>

Accordingly, we believe developing a genetic test that is simple to administer and widely available will be critical to the successful commercialization of Gencaro. The genetic test will be subject to regulation by the FDA and by comparable agencies in various foreign countries. The process of complying with the requirements of the FDA and comparable agencies is costly, time consuming and burdensome. </p>

If regulatory clearance or approval is delayed, or if one or more third-party diagnostic services providers are unable to obtain FDA approval of the genetic test at all or in parallel with the approval of Gencaro, or are unable to commercialize the test successfully and in a manner that effectively supports the commercial efforts for Gencaro, or if the information concerning the differential response to Gencaro resulting from certain genetic variation is not included in the approval label for Gencaro, the commercial launch of Gencaro may be significantly and adversely affected. </p>

The FDA may require additional validation of the genetic test we used in GENETIC-AF prior to any approval of Gencaro or the genetic test or prior to the use of such test in any future clinical trials for Gencaro. We anticipate the genetic test will be required as a condition to prescribing Gencaro. There is no guarantee the FDA will approve the anticipated PMA submission for the genetic test. Even if the genetic test is eventually approved, performing additional validation work necessary to support the PMA, if required, for current or future genetic test products, including one associated with Gencaro, would require additional time and expense and the outcome would be uncertain. Moreover, such delays or increased costs or failures could adversely affect our business, operating results and prospects for commercializing the genetic test.</p>

<p style="margin-top:6pt;margin-bottom:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Any diagnostic for which a third-party diagnostics provider obtains clearance or approval, and the manufacturing processes, reporting requirements, post-approval clinical data and promotional activities for such product, will be subject to continued regulatory review, oversight and periodic inspections by the FDA and other domestic and foreign regulatory bodies. With respect to the genetic test, to the extent applicable, any third-party diagnostics provider and certain of its suppliers will be required to comply with the FDA&#8217;s Quality System Regulation, or QSR, and International Standards Organization, or ISO, requirements which cover the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of any product for which clearance or approval is obtained. Regulatory bodies, such as the FDA, enforce the QSR and other regulations through periodic inspections. The failure by a third-party diagnostics provider, or certain of its third-party manufacturers or suppliers, as the case may be, to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies, or the failure to timely and adequately respond to any adverse inspectional observations or product safety issues, could result in, among other things, enforcement actions. If any of these actions were to occur, it could harm our reputation and cause product sales and profitability of Gencaro, if approved, to suffer and may prevent us from generating revenue or utilizing the genetic test further in any clinical trial. Even if regulatory clearance or approval is granted, such clearance or approval may be subject to limitations on the intended uses for which the product may be marketed and reduce our potential to successfully commercialize the product and generate revenue from the product. </p>

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The genetic test is an important component of the commercial strategy for Gencaro in addition to being required for our clinical trials. We believe that the genetic test helps predict patient response to Gencaro, and that this aspect of the drug is important to its ability to compete effectively with current therapies. The genetic test adds an additional step in the prescribing process, an additional cost for the patient and payors, the risk that the test results may not be rapidly available and the possibility that it may not be available at all to hospitals and medical centers. Although we anticipate that Gencaro, if approved in a timely manner, would be the first genetically-targeted cardiovascular drug, Gencaro will be one of a number of successful drugs in the beta-blocker class currently on the market. Prescribers may be more familiar with these other beta-blockers, and may be resistant to prescribing Gencaro as an AF therapy in patients with HF. For instance, the top-line results of our Phase 2B GENETIC-AF clinical trial indicated that Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate (TOPROL-XL). If our future clinical trials in Gencaro do not show that Gencaro has a clear therapeutic benefit as compared to other drugs in the beta-blocker class currently on the market, then prescribers may be unlikely to prescribe Gencaro to patients, even if approved. Any one of these factors could affect prescriber behavior, which in turn may substantially impede market acceptance of the genetic test, which could cause significant harm to Gencaro&#8217;s ability to compete, and in turn harm our business. </p>

Our board of directors and management team have and will continue to devote substantial time and resources to obtaining additional capital or the consideration and implementation of any such strategic transaction. In addition, conditions in the financial markets may lead to an increased number of biotechnology companies that are also seeking to enter into strategic transactions, which may limit our ability to negotiate favorable terms for any such transaction. Further, our current employees do not have experience in the strategic transaction process, and our previous efforts to enter into a strategic transaction have not been successful. As a result of these and other factors, there is substantial risk that we may not be able to complete a strategic transaction on favorable terms, or at all. The failure to complete such a strategic transaction may materially and adversely affect our business. </p>

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Nasdaq rules impose restrictions on our ability to raise funds through a private offering of our common stock, convertible debt or similar instruments without obtaining stockholder approval. Under Nasdaq rules, an offering of more than 20% of our total shares outstanding at a price per share less than (i) the closing price of our common stock on the Nasdaq Capital Market <font style="Background-color:#FFFFFF;color:#000000;">immediately preceding the signing of the binding agreement, or (ii) the average closing price of our common stock on the Nasdaq Capital Market for the five trading days immediately preceding the signing of the binding agreement</font> requires stockholder approval unless the offering qualifies as a &#8220;public&#160;offering&#8221; for purposes of the Nasdaq rules. As of March 31, 2019, adjusted for the reverse split in April 2019, we had approximately 1.1&#160;million shares of common stock outstanding, 20% of which is approximately 220,000 shares. SEC rules impose restrictions on our ability to raise funds through the registered offering of our securities pursuant to a &#8220;shelf&#8221; registration statement on Form S-3. Under SEC rules, we are prohibited from selling securities under such a registration statement if the aggregate market value of the securities sold thereunder in any twelve-month period exceeds one-third of the market value of our outstanding common stock held by non-affiliates. In&#160;2017, we entered into a sales agreement with an agent to sell, from time to time, our common stock having an aggregate offering price of up to $10.2 million, in one or more &#8220;at the market offerings.&#8221; In January and March&#160;2019, we further amended our sales agreement to increase the maximum aggregate value of shares which we may issue and sell from time to time under this sales agreement from $10.2 million to $13.3 million. As of May 6, 2019, we have sold an aggregate of 592,601 shares of our common stock pursuant to the terms of such sales agreement, as amended, for aggregate gross proceeds of approximately $13.2&#160;million.  Net proceeds received in the period were approximately $12.4&#160;million, after deducting initial expenses for executing the &#8220;at the market offering&#8221; and commissions paid to the placement agent. Due to these sales, we may be limited in our ability to sell securities registered on Form S-3 over the next 12 months, which may substantially limit our ability to effect future financings. In addition, we are currently subject to certain contractual rights of investors arising from our public and private equity financing transactions that limit the nature and price of future public and private financing transactions that we may effect. For example, in January 2013, we entered into separate subscription agreements with certain institutional investors in connection with a private investment in public equity, pursuant to which we sold shares of our common stock and warrants to purchase shares of our common stock to the investors. In connection with this transaction, we agreed that, subject to certain exceptions, we would not, while the warrants issued in such financing are outstanding, effect or enter into an agreement to effect any issuance of common stock or securities convertible into, exercisable for or exchangeable for common stock in a &#8220;variable rate transaction,&#8221; which means a transaction in which we issue or sell any convertible securities either (A)&#160;at a conversion price, exercise price or exchange rate or other price that is based upon and/or varies with the trading prices of, or quotations for, the shares of common stock at any time after the initial issuance of such convertible securities, or (B)&#160;with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of the convertible securities or upon the occurrence of the specified or contingent events directly or indirectly related to our business or the market for our common stock. The restrictions imposed by the terms of our previous offerings, and that could be imposed in future offerings, may limit our access to capital on agreeable terms and delay or make impossible certain otherwise available equity financing opportunities and could severely restrict our access to the capital necessary to conduct our business.&nbsp;&nbsp; </p>

We are years away from commercializing a product and generating any product revenue. As a result, we expect to continue to incur significant operating losses for the foreseeable future. Even if we ultimately receive regulatory approval for Gencaro or our other product candidates, sales of such products may not generate sufficient revenue for it to achieve or maintain profitability. Because of the numerous risks and uncertainties associated with developing therapeutic drugs, we may experience larger than expected future losses and may never reach profitability. </p>

These regulations also vary in important, meaningful ways from country to country. We are not permitted to market a potential drug in the United States until we receive approval of an NDA from the FDA for such drug. We have not received an NDA approval from the FDA for Gencaro or any of our other product candidates. There can be no guarantees with respect to our product candidates that clinical studies will adequately support an NDA, that the products will receive necessary regulatory approvals, or that they will prove to be commercially successful. </p>

This process is expensive and can take many years, and failure can occur at any stage of the testing. Our failure to adequately demonstrate the safety and efficacy of our product candidates will prevent regulatory approval and commercialization of such products. In 2008, we submitted and the FDA accepted our NDA filing for Gencaro for the treatment of chronic HF. In 2009, the FDA issued a Complete Response Letter, or CRL, in which the FDA stated that it could not approve the Gencaro NDA in its current form and specified actions required for approval of the NDA, including conducting an additional Phase 3 clinical trial of Gencaro in patients with HF. We completed a Phase 2B clinical study of Gencaro in HF patients to assess its efficacy in reducing or preventing AF. We enrolled 267 HF patients with AF in the Phase 2B trial. We reported top-line Phase 2B data in February 2018. In February 2019, the FDA approved our SPA request for a Phase 3 clinical trial of Gencaro. Even though the FDA approved our SPA, this product candidate will require years of additional clinical development. Even if we conduct additional studies in accordance with our SPA agreement or further FDA guidance and submit or file a new or amended NDA, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. </p>

Our inability to successfully initiate and effectively complete clinical trials for any product candidate on schedule, or at all, will severely harm our business. Significant delays in clinical development could materially increase product development costs or allow our competitors to bring products to market before we do, impairing our ability to effectively commercialize any future product candidate. We do not know whether planned clinical trials will begin on time, will need to be redesigned or will be completed on schedule, if at all. Clinical trials can be delayed for a variety of reasons, including: </p>

These events have resulted in the withdrawal of certain drug products, revisions to certain drug labeling that further limit use of the drug products and establishment of risk management programs that may, for instance, restrict distribution of drug products. The increased attention to drug safety issues may result in a more cautious approach by the FDA to clinical trials and approval. Data from clinical trials may receive greater scrutiny with respect to safety and the product&#8217;s risk/benefit profile, which may make the FDA or other regulatory authorities more likely to terminate clinical trials before completion, or require longer or additional clinical trials that may result in substantial additional expense, and a delay or failure in obtaining approval or approval for a more limited indication than originally sought. Aside from issues concerning the quality and sufficiency of submitted preclinical and clinical data, the FDA may be constrained by limited resources from reviewing and determining the approvability of the Gencaro NDA in a timely manner. </p>

The FDA could approve Gencaro, but without including some or all of the prescribing information that we have requested. For instance, the FDA could approve Gencaro for AF in a more limited patient population or include additional warnings in the drug&#8217;s label. This, in turn, could substantially and detrimentally impact our ability to successfully commercialize Gencaro and effectively protect our intellectual property rights in Gencaro. </p>

Regulatory approvals may also be subject to significant limitations on the indicated uses or marketing of the product candidates. Potentially costly follow-up or post-marketing clinical studies may be required as a condition of approval to further substantiate safety or efficacy, or to investigate specific issues of interest to the regulatory authority. Previously unknown problems with the product candidate, including adverse events of unanticipated severity or frequency, may result in additional regulatory controls or restrictions on the marketing or use of the product or the need for post marketing studies, and could include suspension or withdrawal of the products from the market. </p>

Quality control and manufacturing procedures must continue to conform to cGMP after approval. Drug manufacturers and their subcontractors are required to register their facilities and products manufactured annually with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA, state and/or other foreign authorities. Any subsequent discovery of problems with a product, or a manufacturing or laboratory facility used by us or our collaborators, may result in restrictions on the product, or on the manufacturing or laboratory facility, including a withdrawal of the drug from the market or suspension of manufacturing. Any changes to an approved product, including the way it is manufactured or promoted, often require FDA approval before the product, as modified, can be marketed. We and our third-party manufacturers will also be subject to ongoing FDA requirements for submission of safety and other post-market information. </p>

Violations of these laws and regulations, including promotion of our products for unapproved uses or failing to disclose risk information, are punishable by criminal and civil sanctions and may result in the issuance of enforcement letters or other enforcement action by the FDA, U.S. Department of Justice, state agencies, or foreign regulatory authorities that could jeopardize our ability to market the product. </p>

Many states have similar laws applicable to items or services reimbursed by commercial insurers. Violations of these laws are punishable by criminal and civil sanctions, including, in some instances, imprisonment and exclusion from participation in federal and state health care programs, including the Medicare, Medicaid and Veterans Affairs healthcare programs. Because of the far-reaching nature of these laws, we may be required to discontinue one or more of our practices to be in compliance with these laws. Healthcare fraud and abuse regulations are complex, and even minor irregularities can potentially give rise to claims that a statute or prohibition has been violated. Any violations of these laws, or any action against us for violations of these laws, even if we successfully defend against it, could have a material adverse effect on our business, financial condition and results of operations. </p>
<p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">We could also become subject to false claims litigation under federal statutes, which can lead to civil money penalties, restitution, criminal fines and imprisonment, and exclusion from participation in Medicare, Medicaid and other federal and state health care programs. These false claims statutes include the False Claims Act, which allows any person to bring a suit on behalf of the federal government alleging submission of false or fraudulent claims, or causing to present such false or fraudulent claims, under federal programs or contracts claims or other violations of the statute and to share in any amounts paid by the entity to the government in fines or settlement. These suits against pharmaceutical companies have increased significantly in volume and breadth in recent years. Some of these suits have been brought on the basis of certain sales practices promoting drug products for unapproved uses. This new growth in litigation has increased the risk that a pharmaceutical company will have to defend a false claim action, pay fines or restitution, or be excluded from the Medicare, Medicaid, Veterans Affairs and other federal and state healthcare programs as a result of an investigation arising out of such action. We may become subject to such litigation and, if we are not successful in defending against such actions, those actions may have a material adverse effect on our business, financial condition and results of operations. We could also become subject to false claims litigation and consumer protection claims under state statutes, which also could lead to civil monetary penalties, restitution, criminal fines and imprisonment, and exclusion from participation in state health care programs. Of note, over the past few years there has been an increased focus on the sales and marketing practices of the pharmaceutical industry at both the federal and state level. Additionally, the law or regulatory policies governing pharmaceuticals may change. New statutory requirements may be enacted or additional regulations may be adopted that could prevent or delay regulatory approval of our product candidates or limit our ability to commercialize our products. We cannot predict the likelihood, nature or extent of adverse government regulation that may arise from future legislation or administrative action, either in the United States or elsewhere. </p>

In addition, we may have little or no control over the sales efforts of those third parties.

We have no experience in drug formulation or manufacturing, and we lack the resources and the capabilities to manufacture any of our product candidates on a clinical or commercial scale. We do not intend to develop facilities for the manufacture of product candidates for clinical trials or commercial purposes in the foreseeable future. We have contracted with Groupe Novasep to manufacture the API for Gencaro. For drug production, we previously contracted with Patheon, Inc. to manufacture the Gencaro tablets. In addition, we contracted with a separate service provider for packaging and distribution of our clinical trial materials. We may also need to contract with similar manufacturers for similar services in connection with any Phase&#160;3 clinical trial of Gencaro. These contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to successfully produce, store and distribute our products. In addition, these manufacturers may have staffing difficulties, may not be able to manufacture our products on a timely basis or may become financially distressed. In the event of errors in forecasting production quantities required to meet demand, natural disaster, equipment malfunctions or failures, technology malfunctions, strikes, lock-outs or work stoppages, regional power outages, product tampering, war or terrorist activities, actions of regulatory authorities, business failure, strike or other difficulty, we may be unable to find an alternative third-party manufacturer in a timely manner and the production of our product candidates would be interrupted, resulting in delays and additional costs, which could impact our ability to commercialize and sell our product candidates. We or our contract manufacturers may also fail to achieve and maintain required manufacturing standards, which could result in patient injury or death, product recalls or withdrawals, an order by governmental authorities to halt production, delays or failures in product testing or delivery, stability testing failures, cost overruns or other problems that could seriously hurt our business. Contract manufacturers also often encounter difficulties involving production yields, quality control and quality assurance, as well as shortages of qualified personnel. In addition, our contract manufacturers are subject to ongoing inspections and regulation by the FDA, the U.S. Drug Enforcement Agency and corresponding foreign and state agencies and they may fail to meet these agencies&#8217; acceptable standards of compliance. If our contract manufacturers fail to comply with applicable governmental regulations, such as quality control, quality assurance and the maintenance of records and documentation, we may not be able to continue production of the API or finished product. If the safety of any API or product supplied is compromised due to failure to adhere to applicable laws or for other reasons, this may jeopardize our regulatory approval for Gencaro and other product candidates, and we may be held liable for any injuries sustained as a result. Upon the occurrence of one of the aforementioned events, the ability to switch manufacturers may be difficult for a number of reasons, including: </p>

While we anticipate that this drug, if approved, would be the first genetically-targeted cardiovascular drug, and potentially the only beta-blocker approved for AF, Gencaro will be one of a number of accepted treatments for AF. In addition, our proposed prescribing information for Gencaro is expected to include a requirement for genetic testing of the patient to ascertain if they have the genotype that we believe responds most favorably to Gencaro. This additional step will add incremental cost and procedures to prescribing Gencaro, which could make it more difficult to compete against existing therapies. </p>

If products with any of these properties are developed, or any of the existing products are better marketed, then prescriptions of Gencaro by physicians and patient use of Gencaro could be significantly reduced or rendered obsolete and noncompetitive. Further, public announcements regarding the development of any such competing drugs could adversely affect the market price of our common stock and the value of our assets. </p>

The degree of market acceptance of Gencaro or our other product candidates will depend on a number of factors, such as its effectiveness and tolerability, as compared with competitive drugs. For instance, the top-line results of our Phase 2B GENETIC-AF clinical trial indicated that Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate (TOPROL&#8209;XL). If our future clinical trials in Gencaro do not show that Gencaro has a clear therapeutic benefit as compared to other drugs in the beta-blocker class currently on the market, then prescribers may be unlikely to prescribe Gencaro to patients, even if approved. Also, prevalence and severity of side-effects could negatively affect market acceptance of Gencaro or our other product candidates. Failure to achieve market acceptance of Gencaro would significantly harm our business. </p>

A primary current trend in the U.S. health care industry is toward cost containment. Large private payors, managed-care organizations, group purchasing organizations and similar organizations are exerting increasing influence on decisions regarding the use of, and reimbursement levels for, particular treatments. Such third-party payors, including Medicare, are challenging the prices charged for medical products and services, and many third-party payors limit reimbursement for newly approved health care products. </p>

The U.S. Congress has enacted legislation to reform the health care system. While we anticipate that this legislation may, over time, increase the number of patients who have insurance coverage for pharmaceutical products, it also imposes cost containment measures that may adversely affect the amount of reimbursement for pharmaceutical products. These measures include increasing the minimum rebates for products covered by Medicaid programs and extending such rebates to drugs dispensed to Medicaid beneficiaries enrolled in Medicaid managed care organizations as well as expansion of the 340(B) Public Health Services drug discount program. In addition, such legislation contains a number of provisions designed to generate the revenues necessary to fund the coverage expansion, including new fees or taxes on certain health-related industries, including medical device manufacturers. Each medical device manufacturer has to pay an excise tax (or sales tax) in an amount equal to 2.3% of the price for which such manufacturer sells its medical devices. Such excise taxes may impact any potential sales of the genetic test if it is approved for marketing. On January 22, 2018, legislation was enacted suspending the medical device tax in 2018 and 2019. It will be reinstated on January 1, 2020, unless a permanent repeal takes place before that date. In foreign jurisdictions there have been, and we expect that there will continue to be, a number of legislative and regulatory proposals aimed at changing the health care system. For example, in some countries other than the United States, pricing of prescription drugs is subject to government control and we expect to see continued efforts to reduce healthcare costs in international markets. </p>

Managed care organizations continue to seek price discounts and, in some cases, to impose restrictions on the coverage of particular drugs. Government efforts to reduce Medicaid expenses may lead to increased use of managed care organizations by Medicaid programs. This may result in managed care organizations influencing prescription decisions for a larger segment of the population and a corresponding constraint on prices and reimbursement for drugs. It is likely that federal and state legislatures and health agencies will continue to focus on additional health care reform in the future although we are unable to predict what additional legislation or regulation, if any, relating to the health care industry or third-party coverage and reimbursement may be enacted in the future or what effect such legislation or regulation would have on our business. We or any strategic partner&#8217;s ability to commercialize Gencaro, or any other product candidates that we may seek to commercialize, is highly dependent on the extent to which coverage and reimbursement for these product candidates will be available from government payors, such as Medicare and Medicaid, private health insurers, including managed care organizations, and other third-party payors, and any change in reimbursement levels could materially and adversely affect our business. Further, the pendency or approval of future proposals or reforms could result in a decrease in our stock price or limit our ability to raise capital or to obtain strategic partnerships or licenses. </p>

The market for licensing and acquiring products and product candidates is intensely competitive and many of our competitors may have greater resources than we do. If we undertake any additional acquisitions, whether of product candidates or other biopharmaceutical companies, the process of integrating an acquired product candidate or complementary company into our business may put a strain on our operations, divert personnel, financial resources and management&#8217;s attention. In 2018, our research and development activities were dedicated to Gencaro and initiating IND-enabling development activities with AB171. We expect our research and development activities in 2019, subject to obtaining additional financing, will be focused on regulatory activities related to Gencaro, initiating the PRECISION&#8209;AF clinical trial and continuing IND-enabling development activities with AB171. If we are not able to substantially expand our research and development efforts, or identify, or license or acquire other products or product candidates or complete future acquisitions, then we will likely be unable expand our pipeline of product candidates. In addition, any future acquisition would give rise to additional operating costs and will likely require us to seek additional financing. Future acquisitions could result in additional issuances of equity securities that would dilute the ownership of existing stockholders. Future acquisitions could also result in the incurrence of debt, contingent liabilities or the amortization of expenses related to other intangible assets, any of which could adversely affect our operating results. </p>

In addition, we might be required to identify one or more collaborators in these foreign countries to develop, seek approval for and manufacture our products and any companion genetic test for Gencaro. If we decide to pursue regulatory approvals and commercialization of our product candidates internationally, we may not be able to obtain the required foreign regulatory approvals on a timely basis, if at all, and any failure to do so may cause us to incur additional costs or prevent us from marketing our products in foreign countries, which may have a material adverse effect on our business, financial condition and results of operations. </p>

Our management, including our principal executive officer and principal financial officer, does not expect that our internal control over financial reporting will prevent all error and all fraud. We continue to operate with a small staff for financial reporting. Though the process and design of our internal controls over financial reporting have not been altered, the small number of staff involved in financial reporting may limit our ability to properly segregate internal control procedures which could result in deficiencies or material weaknesses in our internal controls in the future. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system&#8217;s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud involving a company have been, or will be, detected. The design of any system of controls is based in part on certain assumptions about the&#160;likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become ineffective because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. We cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal control over financial reporting in the future. A material weakness in our internal control over financial reporting would require management to consider our internal control over financial reporting as ineffective. If our internal control over financial reporting is not considered effective, we may experience a loss of public confidence, which could have an adverse effect on our business and on the market price of our common stock. </p>

These laws include several requirements relating to the consent of the individuals to whom the personal data relates, limitations on data processing, establishing a legal basis for processing, notification of data processing obligations or security incidents to appropriate data protection authorities or data subjects, the security and confidentiality of the personal data and various rights that data subjects may exercise.&nbsp;&nbsp;</font></p>

Switzerland has adopted similar restrictions. Although there are legal mechanisms to allow for the transfer of personal data from the EEA and Switzerland to the United States, uncertainty about compliance with European Union data protection laws remains. For example, ongoing legal challenges in Europe to the mechanisms allowing companies to transfer personal data from the EEA to the United States could result in further limitations on the ability to transfer personal data across borders, particularly if governments are unable or unwilling to reach new or maintain existing agreements that support cross-border data transfers, such as the European Union-U.S. and Swiss-U.S. Privacy Shield framework.

Companies that violate the GDPR can face fines of up to the greater of 20 million Euros or 4% of their worldwide annual turnover (revenue). The GDPR increases our responsibility and potential liability in relation to personal data that we process, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR and other EU and international data protection rules<font style="color:#000000;">.</font></p>

Our ability to develop and commercialize Gencaro is dependent on numerous factors, including some factors that are outside of our control. CPEC has the right to terminate our license if we materially breach our obligations under the license agreement and fail to cure any such breach within the terms of the license. In October 2017, we entered into an agreement with Aeolus pursuant to which we acquired Aeolus&#8217; minority membership interest in CPEC. The transaction effectively buys-out Aeolus&#8217; royalty interest thereby reducing or eliminating the stated milestone and royalty obligations that could be payable by us, if Gencaro receives regulatory approval and is commercialized. </p>

The patent positions of biotechnology companies involve complex legal and factual questions, and we cannot be certain that our patents and licenses will successfully preclude others from using our technology. Consequently, we cannot be certain that any of our patents will provide significant market protection or will not be circumvented or challenged and found to be unenforceable or invalid. In some cases, patent applications in the United States and certain other jurisdictions are maintained in secrecy until patents issue, and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain of the priority of inventions covered by pending patent applications. Moreover, we may have to participate in interference proceedings declared by the U.S. Patent and Trademark Office to determine priority of invention, in opposition proceedings in a foreign patent office, or in a post-grant challenge proceeding such as an <font style="font-style:italic;">ex parte</font> reexamination or <font style="font-style:italic;">inter partes</font> review at the U.S. Patent and Trademark Office, any of which could result in substantial cost to us, even if the eventual outcome is favorable. There can be no assurance that a court of competent jurisdiction would hold any claims in any issued patent to be valid. An adverse outcome could subject us to significant liabilities to third parties, require disputed rights to be licensed from third parties or require us to cease using such technology. Regardless of merit, the listing of patents in the FDA Orange Book for Gencaro may be challenged as being improperly listed. We may have to defend against such claims and possible associated antitrust issues. We could also incur substantial costs in seeking to enforce our proprietary rights against infringement. </p>

We have obtained patents that claim methods involving Gencaro after a patient&#8217;s receptor genotype has been determined. We anticipate that any NDA for Gencaro will request a label including a claim that efficacy varies based on receptor genotype and a recommendation in the prescribing information that prospective patients be tested for their receptor genotype. We believe that under applicable law, a generic bucindolol label would likely be required to include this recommendation as it pertains directly to the safe or efficacious use of the drug. Such a label may be considered as inducing infringement, carrying the same liability as direct infringement. If the label with the genotype information for Gencaro is not approved, or if generic labels are not required to copy the approved label, competitors could have an easier path to introduce competing products and our business may suffer. The approved label may not contain language covered by the patents, or we may be unsuccessful in enforcing them. </p>

Any issued patent may not be sufficient to prevent others from competing with us. Further, we have trade secrets relating to Gencaro, and such trade secrets may become known or independently discovered. Our issued patents and those that may issue in the future, or those licensed to us, may be challenged, opposed, invalidated or circumvented, which could allow competitors to market similar products or limit the patent protection term of our product candidates. All of these factors may affect our competitive position. </p>

Litigation may be necessary to assert infringement claims, enforce patent rights, protect trade secrets or know-how and determine the enforceability, scope and validity of certain proprietary rights. Litigation may even be necessary to defend disputes of inventorship or ownership of proprietary rights. The defense and prosecution of intellectual property lawsuits, U.S. Patent and Trademark Office interference proceedings, and related legal and administrative proceedings (e.g., a reexamination, <font style="font-style:italic;">inter partes</font> review, or post-grant review) in the United States and internationally involve complex legal and factual questions. As a result, such proceedings are costly and time-consuming to pursue, and their outcome is uncertain. </p>

Any public announcements related to litigation or interference proceedings initiated or threatened against us could cause our stock price to decline. Adverse outcomes in patent litigation may potentially subject us to antitrust litigation which, regardless of the outcome, would adversely affect our business. An adverse determination may subject us to the loss of our proprietary position or to significant liabilities, or require us to seek licenses that may include substantial cost and ongoing royalties. Licenses may not be available from third parties, or may not be obtainable on satisfactory terms. An adverse determination or a failure to obtain necessary licenses may restrict or prevent us from manufacturing and selling our products, if any. These outcomes could materially harm our business, financial condition and results of operations. </p>

These broad market fluctuations may also adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company&#8217;s securities, stockholders have often instituted class action securities litigation against those companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm our profitability and reputation. </p>

As of March 31, 2019, approximately 1.1&#160;million shares of common stock were outstanding, and all of these shares are freely transferable without restriction or further registration under the Securities Act, except for shares held by our directors, officers and other affiliates and unregistered shares held by non-affiliates. The sale of these additional shares, or the perception that such sales may occur, could depress the market price of our common stock. </p>

Once a warrant is exercised, if the shares of our common stock issued upon the exercise of any such warrant are not available for sale in the open market without further registration under the Securities Act, then the holder can arrange for the resale of shares either by invoking any applicable registration rights, causing the shares to be registered under the Securities Act and thus freely transferable, or by relying on an exemption to the Securities Act. For instance, in July 2015, we filed a registration statement on Form&#160;S-3 which registered for resale an aggregate of 0.1 million shares of our common stock issuable upon exercise of outstanding warrants. If these registration rights, or similar registration rights that may apply to securities we may issue in the future, are exercised, it could result in additional sales of our common stock in the market, which may have an adverse effect on our stock price. </p>

If and when these options are exercised, such shares will be available for sale in the open market without further registration under the Securities Act. The existence of these outstanding options may negatively affect our ability to complete future equity financings at acceptable prices and on acceptable terms. The exercise of those options, and the prompt resale of shares of our common stock received, may also result in downward pressure on the price of our common stock. </p>

The bylaws provide, however, that our stockholders may call a special meeting of stockholders only upon a request of stockholders owning at least 50% of our outstanding common stock. These provisions of our certificate of incorporation and bylaws could discourage potential acquisition proposals and could delay or prevent a change in control. We designed these provisions to reduce our vulnerability to unsolicited acquisition proposals and to discourage certain tactics that may be used in proxy fights. These provisions, however, could also have the effect of discouraging others from making tender offers for our shares. As a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management. </p>

Therefore, the rights of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of our preferred stock that may be issued in the future. In addition, the issuance of preferred stock could have a dilutive effect on the holdings of our current stockholders. </p>

&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;ARCA biopharma, Inc. (the Company or ARCA), a Delaware corporation, is headquartered in Westminster, Colorado. The Company is a biopharmaceutical company applying a precision medicine approach to developing genetically-targeted therapies for cardiovascular diseases. The Company&amp;#8217;s lead product candidate, Gencaro&amp;#8482; (bucindolol hydrochloride), is an investigational, pharmacologically unique beta-blocker and mild vasodilator that ARCA is developing for the potential treatment of atrial fibrillation (AF) in certain patients who also have heart failure (HF). &lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In February 2018, the Company completed its Phase 2B clinical superiority trial, known as GENETIC-AF, in which the Company evaluated Gencaro for the treatment of AF in HF patients. In the trial, Gencaro was evaluated against an active comparator, the beta-blocker TOPROL-XL (metoprolol succinate), a drug indicated for the treatment of HF patients that is also prescribed, but not approved, for treating AF.&amp;nbsp;&amp;nbsp; Enrollment in GENETIC-AF was limited to patients that possess the specific genotype that the Company believes enhances Gencaro&amp;#8217;s potential therapeutic effects.&amp;nbsp;&amp;nbsp;The planned development program of Gencaro is, in part, based on the results of the Company&amp;#8217;s completed GENETIC-AF Phase 2B clinical trial and a prospectively designed DNA substudy of adrenergic receptor polymorphisms in the BEST trial, a previous Phase&amp;#160;3 study of HF patients.&amp;nbsp;&amp;nbsp;&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;GENETIC-AF was a Phase 2B, multi-center, randomized, double-blind, clinical superiority trial comparing the safety and efficacy of Gencaro against TOPROL-XL, that enrolled 267 HF patients. The Company reported top-line Phase 2B trial data in February 2018. Overall, Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate; however, trends for benefit in favor of bucindolol were observed in multiple subpopulations of patients in the trial. Based on these data, the Company believes further clinical development of Gencaro is warranted. Following review of the Phase 2 GENETIC-AF trial results, as well as its alignment with previous Phase 3 pharmacogenetic substudy data from the BEST trial, the FDA stated that data from a single pivotal Phase 3 clinical trial may be sufficient to support approval of Gencaro for the treatment of AF in patients with HF. The Company, in consultation with the FDA, developed key elements of the Phase 3 clinical trial needed to support a potential New Drug Application (NDA), details of which were submitted for evaluation and confirmed via the FDA&amp;#8217;s Special Protocol Assessment (SPA) process in February 2019.&amp;nbsp;&amp;nbsp;   &lt;font style="font-size:12pt;"&gt; &lt;/font&gt;&lt;/p&gt;

The Company has not generated revenue to date and has incurred substantial losses and negative cash flows from operations since its inception.&amp;nbsp;&amp;nbsp;The Company has historically funded its operations through issuances of common and preferred stock.&amp;nbsp;&amp;nbsp; &lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The Company believes that its current cash and cash equivalents will be sufficient to fund its operations, at its projected cost structure, through the end of the third quarter of 2019. In light of the significant uncertainties regarding clinical development timelines and costs for developing drugs such as Gencaro, the Company will need to raise additional capital to finance the Company&amp;#8217;s future operations and any additional development of Gencaro or any other product candidates. If the Company is delayed in completing or is unable to complete additional financing and/or a strategic transaction, the Company may discontinue its development activities or operations. &lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;"&gt;&amp;nbsp;&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Due to the current status of the Gencaro development program, the current amount of cash and cash equivalents held, the anticipated costs to be incurred for existing operations as well as exploring other corporate strategic alternatives, and the uncertainty of the Company&amp;#8217;s ability to raise a significant amount of capital, management has determined there is substantial doubt about the Company&amp;#8217;s ability to continue as a going concern from one year after the Company&amp;#8217;s financial statements have been issued.&amp;nbsp;&amp;nbsp;In May 2019, the Company has taken efforts to reduce personnel costs, including reduction of executive management salaries. The Company could delay or cancel certain planned expenditures related to its drug development programs and/or implement additional cost reduction measures to conserve its cash balances; however, there is no assurance that those measures would be adequate to allow the Company to continue as a going concern for a period beyond one year from the issuance of these financial statements.&amp;nbsp;&amp;nbsp;These financial statements have been prepared with the assumption that the Company will continue as a going concern and will be able to realize its assets and discharge its liabilities in the normal course of business and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the inability of the Company to continue as a going concern. The Company may not be able to raise sufficient capital on acceptable terms, or at all, to continue development of Gencaro or to otherwise continue operations and may not be able to execute any strategic transaction.&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The Company&amp;#8217;s liquidity, and its ability to raise additional capital or complete any strategic transaction, depends on a number of factors, including, but not limited to, the following: &lt;/p&gt;

The Company also cannot predict what consideration might be available, if any, to the Company or its stockholders, in connection with any strategic transaction. Should strategic alternatives or additional capital not be available to the Company, or not be available on acceptable terms, the Company may be unable to realize value from its assets and discharge its liabilities in the normal course of business which may, among other alternatives, cause the Company to further delay, substantially reduce or discontinue operational activities to conserve its cash resources.  &lt;/p&gt;

These unaudited financial statements should be read in conjunction with the audited financial statements and footnotes thereto for the year ended December&amp;#160;31, 2018 included in the Company&amp;#8217;s Annual Report on Form 10-K filed with the Securities and Exchange Commission. Amounts presented are rounded to the nearest thousand, where indicated, except per share data and par values.&lt;/p&gt;

The Company has no off-balance-sheet concentrations of credit risk, such as foreign exchange contracts, option contracts, or foreign currency hedging arrangements.

Such balances may at times exceed the insured amount. &lt;/p&gt;

Operating ROU lease assets are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company&amp;#8217;s lease does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments.&amp;nbsp;&amp;nbsp;The Company&amp;#8217;s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.&lt;/p&gt;

This process involves identifying services that third parties have performed on the Company&amp;#8217;s behalf and estimating the level of service performed and the associated cost incurred for these services as of the balance sheet date. Examples of estimated accrued outsourcing expenses include contract service fees, such as fees payable to contract manufacturers in connection with the production of materials related to the Company&amp;#8217;s drug product, and service fees from clinical research organizations. The Company develops estimates of liabilities using its judgment based upon the facts and circumstances known at the time. &lt;/p&gt;

In July 2018, FASB issued ASU&amp;#160;No.&amp;#160;2018&amp;#8209;11, Topic 842 - &lt;font style="font-style:italic;"&gt;Targeted Improvements&lt;/font&gt;. The update requires modified retrospective transition, with the option to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment and elect various practical expedients.&amp;nbsp;&amp;nbsp;The guidance is effective for fiscal years beginning after December 15, 2018. The Company applied the practical expedients permitted within the guidance, which allows the Company to carryforward its historical lease classification, and to apply the transition option which does not require application of the guidance to comparative periods in the year of adoption.  The Company adopted ASU 2016-02 effective January 1, 2019.&amp;nbsp;&amp;nbsp;As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $80,000, which represents the present value of the remaining lease payments of approximately $83,000, discounted using the Company&amp;#8217;s incremental borrowing rate of 7.5%, and (b) a right-of-use asset of approximately $60,000 which represents the lease liability of $80,000 adjusted for accrued rent of approximately $20,000. Adoption of this standard did not have a material impact on the financial statements.&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In August 2018, the FASB issued ASU No. 2018-13, &lt;font style="font-style:italic;"&gt;Fair Value Measurement (Topic 820): Disclosure Framework&amp;#8212;Changes to the Disclosure Requirements for Fair Value Measurement&lt;/font&gt;, which modifies the disclosure requirements on fair value measurements. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.&amp;nbsp;&amp;nbsp;Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of the amendments on the financial statement disclosures. Since the amendments impact only disclosure requirements, the Company does not expect the amendments to have a material impact on the financial statements.&lt;/p&gt;

CPEC is a licensing subsidiary of Indevus Pharmaceuticals Inc. (a wholly owned subsidiary of Endo Pharmaceuticals), holding ownership rights to certain clinical trial data of Gencaro.&amp;nbsp;&amp;nbsp;Under the terms of its license agreement with CPEC, the Company will incur milestone and royalty obligations upon the occurrence of certain events.&amp;nbsp;&amp;nbsp;If the FDA grants marketing approval for Gencaro, the license agreement states that the Company will owe CPEC a milestone payment of $8.0&amp;#160;million within six months after FDA approval. The license agreement states that a milestone payment of up to $5.0 million in the aggregate shall be paid upon regulatory marketing approval in Europe and Japan.&amp;nbsp;&amp;nbsp;The license agreement also states that the Company&amp;#8217;s royalty obligation ranges from 12.5% to 25% of revenue from the related product based on achievement of specified product sales levels, including a 5% royalty that CPEC is obligated to pay under its original license agreement for Gencaro. The agreement states that the Company has the right to buy down the royalties to a range of 12.5% to 17% by making a payment to CPEC within six months of regulatory approval. &lt;/p&gt;

(the Company or ARCA), a Delaware corporation, is headquartered in Westminster, Colorado. The Company is a biopharmaceutical company applying a precision medicine approach to developing genetically-targeted therapies for cardiovascular diseases. The Company&amp;#8217;s lead product candidate, Gencaro&amp;#8482; (bucindolol hydrochloride), is an investigational, pharmacologically unique beta-blocker and mild vasodilator that ARCA is developing for the potential treatment of atrial fibrillation (AF) in certain patients who also have heart failure (HF). &lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In February 2018, the Company completed its Phase 2B clinical superiority trial, known as GENETIC-AF, in which the Company evaluated Gencaro for the treatment of AF in HF patients. In the trial, Gencaro was evaluated against an active comparator, the beta-blocker TOPROL-XL (metoprolol succinate), a drug indicated for the treatment of HF patients that is also prescribed, but not approved, for treating AF.&amp;nbsp;&amp;nbsp; Enrollment in GENETIC-AF was limited to patients that possess the specific genotype that the Company believes enhances Gencaro&amp;#8217;s potential therapeutic effects.&amp;nbsp;&amp;nbsp;The planned development program of Gencaro is, in part, based on the results of the Company&amp;#8217;s completed GENETIC-AF Phase 2B clinical trial and a prospectively designed DNA substudy of adrenergic receptor polymorphisms in the BEST trial, a previous Phase&amp;#160;3 study of HF patients.&amp;nbsp;&amp;nbsp;&lt;/p&gt;

The Company reported top-line Phase 2B trial data in February 2018. Overall, Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate; however, trends for benefit in favor of bucindolol were observed in multiple subpopulations of patients in the trial. Based on these data, the Company believes further clinical development of Gencaro is warranted. Following review of the Phase 2 GENETIC-AF trial results, as well as its alignment with previous Phase 3 pharmacogenetic substudy data from the BEST trial, the FDA stated that data from a single pivotal Phase 3 clinical trial may be sufficient to support approval of Gencaro for the treatment of AF in patients with HF. The Company, in consultation with the FDA, developed key elements of the Phase 3 clinical trial needed to support a potential New Drug Application (NDA), details of which were submitted for evaluation and confirmed via the FDA&amp;#8217;s Special Protocol Assessment (SPA) process in February 2019.&amp;nbsp;&amp;nbsp;   &lt;font style="font-size:12pt;"&gt; &lt;/font&gt;&lt;/p&gt;

The Company has not generated revenue to date and has incurred substantial losses and negative cash flows from operations since its inception.&amp;nbsp;&amp;nbsp;The Company has historically funded its operations through issuances of common and preferred stock.&amp;nbsp;&amp;nbsp; &lt;/p&gt;

In light of the significant uncertainties regarding clinical development timelines and costs for developing drugs such as Gencaro, the Company will need to raise additional capital to finance the Company&amp;#8217;s future operations and any additional development of Gencaro or any other product candidates. If the Company is delayed in completing or is unable to complete additional financing and/or a strategic transaction, the Company may discontinue its development activities or operations. &lt;/p&gt;

The Company could delay or cancel certain planned expenditures related to its drug development programs and/or implement additional cost reduction measures to conserve its cash balances; however, there is no assurance that those measures would be adequate to allow the Company to continue as a going concern for a period beyond one year from the issuance of these financial statements.&amp;nbsp;&amp;nbsp;These financial statements have been prepared with the assumption that the Company will continue as a going concern and will be able to realize its assets and discharge its liabilities in the normal course of business and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the inability of the Company to continue as a going concern. The Company may not be able to raise sufficient capital on acceptable terms, or at all, to continue development of Gencaro or to otherwise continue operations and may not be able to execute any strategic transaction.&lt;/p&gt;

Operating ROU lease assets are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company&amp;#8217;s lease does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments.&amp;nbsp;&amp;nbsp;The Company&amp;#8217;s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.&lt;/p&gt;</us-gaap:LesseeLeasesPolicyTextBlock>

This process involves identifying services that third parties have performed on the Company&amp;#8217;s behalf and estimating the level of service performed and the associated cost incurred for these services as of the balance sheet date. Examples of estimated accrued outsourcing expenses include contract service fees, such as fees payable to contract manufacturers in connection with the production of materials related to the Company&amp;#8217;s drug product, and service fees from clinical research organizations. The Company develops estimates of liabilities using its judgment based upon the facts and circumstances known at the time. &lt;/p&gt;</abio:AccruedOutsourcingExpensesPolicyTextBlock>

In July 2018, FASB issued ASU&amp;#160;No.&amp;#160;2018&amp;#8209;11, Topic 842 - &lt;font style="font-style:italic;"&gt;Targeted Improvements&lt;/font&gt;. The update requires modified retrospective transition, with the option to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment and elect various practical expedients.&amp;nbsp;&amp;nbsp;The guidance is effective for fiscal years beginning after December 15, 2018. The Company applied the practical expedients permitted within the guidance, which allows the Company to carryforward its historical lease classification, and to apply the transition option which does not require application of the guidance to comparative periods in the year of adoption.  The Company adopted ASU 2016-02 effective January 1, 2019.&amp;nbsp;&amp;nbsp;As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $80,000, which represents the present value of the remaining lease payments of approximately $83,000, discounted using the Company&amp;#8217;s incremental borrowing rate of 7.5%, and (b) a right-of-use asset of approximately $60,000 which represents the lease liability of $80,000 adjusted for accrued rent of approximately $20,000. Adoption of this standard did not have a material impact on the financial statements.&lt;/p&gt;
&lt;p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;In August 2018, the FASB issued ASU No. 2018-13, &lt;font style="font-style:italic;"&gt;Fair Value Measurement (Topic 820): Disclosure Framework&amp;#8212;Changes to the Disclosure Requirements for Fair Value Measurement&lt;/font&gt;, which modifies the disclosure requirements on fair value measurements. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.&amp;nbsp;&amp;nbsp;Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of the amendments on the financial statement disclosures. Since the amendments impact only disclosure requirements, the Company does not expect the amendments to have a material impact on the financial statements.&lt;/p&gt;

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">ARCA biopharma, Inc. (the Company or ARCA), a Delaware corporation, is headquartered in Westminster, Colorado. The Company is a biopharmaceutical company applying a precision medicine approach to developing genetically-targeted therapies for cardiovascular diseases. The Company&#8217;s lead product candidate, Gencaro&#8482; (bucindolol hydrochloride), is an investigational, pharmacologically unique beta-blocker and mild vasodilator that ARCA is developing for the potential treatment of atrial fibrillation (AF) in certain patients who also have heart failure (HF). </p>
<p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In February 2018, the Company completed its Phase 2B clinical superiority trial, known as GENETIC-AF, in which the Company evaluated Gencaro for the treatment of AF in HF patients. In the trial, Gencaro was evaluated against an active comparator, the beta-blocker TOPROL-XL (metoprolol succinate), a drug indicated for the treatment of HF patients that is also prescribed, but not approved, for treating AF.&nbsp;&nbsp; Enrollment in GENETIC-AF was limited to patients that possess the specific genotype that the Company believes enhances Gencaro&#8217;s potential therapeutic effects.&nbsp;&nbsp;The planned development program of Gencaro is, in part, based on the results of the Company&#8217;s completed GENETIC-AF Phase 2B clinical trial and a prospectively designed DNA substudy of adrenergic receptor polymorphisms in the BEST trial, a previous Phase&#160;3 study of HF patients.&nbsp;&nbsp;</p>
<p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">GENETIC-AF was a Phase 2B, multi-center, randomized, double-blind, clinical superiority trial comparing the safety and efficacy of Gencaro against TOPROL-XL, that enrolled 267 HF patients. The Company reported top-line Phase 2B trial data in February 2018. Overall, Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate; however, trends for benefit in favor of bucindolol were observed in multiple subpopulations of patients in the trial. Based on these data, the Company believes further clinical development of Gencaro is warranted. Following review of the Phase 2 GENETIC-AF trial results, as well as its alignment with previous Phase 3 pharmacogenetic substudy data from the BEST trial, the FDA stated that data from a single pivotal Phase 3 clinical trial may be sufficient to support approval of Gencaro for the treatment of AF in patients with HF. The Company, in consultation with the FDA, developed key elements of the Phase 3 clinical trial needed to support a potential New Drug Application (NDA), details of which were submitted for evaluation and confirmed via the FDA&#8217;s Special Protocol Assessment (SPA) process in February 2019.&nbsp;&nbsp;   <font style="font-size:12pt;"> </font></p>

The Company has not generated revenue to date and has incurred substantial losses and negative cash flows from operations since its inception.&nbsp;&nbsp;The Company has historically funded its operations through issuances of common and preferred stock.&nbsp;&nbsp; </p>

In light of the significant uncertainties regarding clinical development timelines and costs for developing drugs such as Gencaro, the Company will need to raise additional capital to finance the Company&#8217;s future operations and any additional development of Gencaro or any other product candidates. If the Company is delayed in completing or is unable to complete additional financing and/or a strategic transaction, the Company may discontinue its development activities or operations. </p>

<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Due to the current status of the Gencaro development program, the current amount of cash and cash equivalents held, the anticipated costs to be incurred for existing operations as well as exploring other corporate strategic alternatives, and the uncertainty of the Company&#8217;s ability to raise a significant amount of capital, management has determined there is substantial doubt about the Company&#8217;s ability to continue as a going concern from one year after the Company&#8217;s financial statements have been issued.&nbsp;&nbsp;In May 2019, the Company has taken efforts to reduce personnel costs, including reduction of executive management salaries. The Company could delay or cancel certain planned expenditures related to its drug development programs and/or implement additional cost reduction measures to conserve its cash balances; however, there is no assurance that those measures would be adequate to allow the Company to continue as a going concern for a period beyond one year from the issuance of these financial statements.&nbsp;&nbsp;These financial statements have been prepared with the assumption that the Company will continue as a going concern and will be able to realize its assets and discharge its liabilities in the normal course of business and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the inability of the Company to continue as a going concern. The Company may not be able to raise sufficient capital on acceptable terms, or at all, to continue development of Gencaro or to otherwise continue operations and may not be able to execute any strategic transaction.</p>

If the Company raises additional funds through the incurrence of indebtedness, the obligations related to such indebtedness would be senior to rights of holders of the Company&#8217;s capital stock and could contain covenants that would restrict the Company&#8217;s operations. The Company also cannot predict what consideration might be available, if any, to the Company or its stockholders, in connection with any strategic transaction. Should strategic alternatives or additional capital not be available to the Company, or not be available on acceptable terms, the Company may be unable to realize value from its assets and discharge its liabilities in the normal course of business which may, among other alternatives, cause the Company to further delay, substantially reduce or discontinue operational activities to conserve its cash resources.  </p>

Operating ROU lease assets are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company&#8217;s lease does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments.&nbsp;&nbsp;The Company&#8217;s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.</p>

This process involves identifying services that third parties have performed on the Company&#8217;s behalf and estimating the level of service performed and the associated cost incurred for these services as of the balance sheet date. Examples of estimated accrued outsourcing expenses include contract service fees, such as fees payable to contract manufacturers in connection with the production of materials related to the Company&#8217;s drug product, and service fees from clinical research organizations.

In July 2018, FASB issued ASU&#160;No.&#160;2018&#8209;11, Topic 842 - <font style="font-style:italic;">Targeted Improvements</font>. The update requires modified retrospective transition, with the option to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment and elect various practical expedients.&nbsp;&nbsp;The guidance is effective for fiscal years beginning after December 15, 2018. The Company applied the practical expedients permitted within the guidance, which allows the Company to carryforward its historical lease classification, and to apply the transition option which does not require application of the guidance to comparative periods in the year of adoption.  The Company adopted ASU 2016-02 effective January 1, 2019.&nbsp;&nbsp;As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $80,000, which represents the present value of the remaining lease payments of approximately $83,000, discounted using the Company&#8217;s incremental borrowing rate of 7.5%, and (b) a right-of-use asset of approximately $60,000 which represents the lease liability of $80,000 adjusted for accrued rent of approximately $20,000. Adoption of this standard did not have a material impact on the financial statements.</p>

The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.&nbsp;&nbsp;Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of the amendments on the financial statement disclosures. Since the amendments impact only disclosure requirements, the Company does not expect the amendments to have a material impact on the financial statements.</p>

CPEC is a licensing subsidiary of Indevus Pharmaceuticals Inc. (a wholly owned subsidiary of Endo Pharmaceuticals), holding ownership rights to certain clinical trial data of Gencaro.&nbsp;&nbsp;Under the terms of its license agreement with CPEC, the Company will incur milestone and royalty obligations upon the occurrence of certain events.&nbsp;&nbsp;If the FDA grants marketing approval for Gencaro, the license agreement states that the Company will owe CPEC a milestone payment of $8.0&#160;million within six months after FDA approval. The license agreement states that a milestone payment of up to $5.0 million in the aggregate shall be paid upon regulatory marketing approval in Europe and Japan.&nbsp;&nbsp;The license agreement also states that the Company&#8217;s royalty obligation ranges from 12.5% to 25% of revenue from the related product based on achievement of specified product sales levels, including a 5% royalty that CPEC is obligated to pay under its original license agreement for Gencaro. The agreement states that the Company has the right to buy down the royalties to a range of 12.5% to 17% by making a payment to CPEC within six months of regulatory approval. </p>

(Aeolus) pursuant to which the Company acquired Aeolus&#8217; minority membership interest in CPEC.&nbsp;&nbsp;The transaction effectively bought out Aeolus&#8217; royalty interest thereby reducing or eliminating the stated milestone and royalty obligations that could be payable by the Company, if Gencaro receives regulatory approval and is commercialized.&nbsp;&nbsp;As a result of this transaction, the Company, together with Endo Pharmaceuticals, Inc., indirectly hold the remaining licensee rights of CPEC to certain Gencaro clinical data, discussed above.&nbsp;&nbsp;The acquisition cost of this interest did not have a material impact on the Company&#8217;s financial statements.</p><span></span>

<p style="margin-bottom:0pt;margin-top:6pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">ARCA biopharma, Inc. (the Company or ARCA), a Delaware corporation, is headquartered in Westminster, Colorado. The Company is a biopharmaceutical company applying a precision medicine approach to developing genetically-targeted therapies for cardiovascular diseases. The Company&#8217;s lead product candidate, Gencaro&#8482; (bucindolol hydrochloride), is an investigational, pharmacologically unique beta-blocker and mild vasodilator that ARCA is developing for the potential treatment of atrial fibrillation (AF) in certain patients who also have heart failure (HF). </p>
<p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In February 2018, the Company completed its Phase 2B clinical superiority trial, known as GENETIC-AF, in which the Company evaluated Gencaro for the treatment of AF in HF patients. In the trial, Gencaro was evaluated against an active comparator, the beta-blocker TOPROL-XL (metoprolol succinate), a drug indicated for the treatment of HF patients that is also prescribed, but not approved, for treating AF.&nbsp;&nbsp; Enrollment in GENETIC-AF was limited to patients that possess the specific genotype that the Company believes enhances Gencaro&#8217;s potential therapeutic effects.&nbsp;&nbsp;The planned development program of Gencaro is, in part, based on the results of the Company&#8217;s completed GENETIC-AF Phase 2B clinical trial and a prospectively designed DNA substudy of adrenergic receptor polymorphisms in the BEST trial, a previous Phase&#160;3 study of HF patients.&nbsp;&nbsp;</p>
<p style="margin-bottom:0pt;margin-top:12pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">GENETIC-AF was a Phase 2B, multi-center, randomized, double-blind, clinical superiority trial comparing the safety and efficacy of Gencaro against TOPROL-XL, that enrolled 267 HF patients. The Company reported top-line Phase 2B trial data in February 2018. Overall, Gencaro demonstrated a similar treatment benefit compared to the active comparator, metoprolol succinate; however, trends for benefit in favor of bucindolol were observed in multiple subpopulations of patients in the trial. Based on these data, the Company believes further clinical development of Gencaro is warranted. Following review of the Phase 2 GENETIC-AF trial results, as well as its alignment with previous Phase 3 pharmacogenetic substudy data from the BEST trial, the FDA stated that data from a single pivotal Phase 3 clinical trial may be sufficient to support approval of Gencaro for the treatment of AF in patients with HF. The Company, in consultation with the FDA, developed key elements of the Phase 3 clinical trial needed to support a potential New Drug Application (NDA), details of which were submitted for evaluation and confirmed via the FDA&#8217;s Special Protocol Assessment (SPA) process in February 2019.&nbsp;&nbsp;   <font style="font-size:12pt;"> </font></p>

The Company could delay or cancel certain planned expenditures related to its drug development programs and/or implement additional cost reduction measures to conserve its cash balances; however, there is no assurance that those measures would be adequate to allow the Company to continue as a going concern for a period beyond one year from the issuance of these financial statements.&nbsp;&nbsp;These financial statements have been prepared with the assumption that the Company will continue as a going concern and will be able to realize its assets and discharge its liabilities in the normal course of business and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the inability of the Company to continue as a going concern. The Company may not be able to raise sufficient capital on acceptable terms, or at all, to continue development of Gencaro or to otherwise continue operations and may not be able to execute any strategic transaction.</p>

If the Company raises additional funds through the incurrence of indebtedness, the obligations related to such indebtedness would be senior to rights of holders of the Company&#8217;s capital stock and could contain covenants that would restrict the Company&#8217;s operations. The Company also cannot predict what consideration might be available, if any, to the Company or its stockholders, in connection with any strategic transaction. Should strategic alternatives or additional capital not be available to the Company, or not be available on acceptable terms, the Company may be unable to realize value from its assets and discharge its liabilities in the normal course of business which may, among other alternatives, cause the Company to further delay, substantially reduce or discontinue operational activities to conserve its cash resources.  </p><span></span>

In July 2018, FASB issued ASU&#160;No.&#160;2018&#8209;11, Topic 842 - <font style="font-style:italic;">Targeted Improvements</font>. The update requires modified retrospective transition, with the option to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment and elect various practical expedients.&nbsp;&nbsp;The guidance is effective for fiscal years beginning after December 15, 2018. The Company applied the practical expedients permitted within the guidance, which allows the Company to carryforward its historical lease classification, and to apply the transition option which does not require application of the guidance to comparative periods in the year of adoption.  The Company adopted ASU 2016-02 effective January 1, 2019.&nbsp;&nbsp;As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $80,000, which represents the present value of the remaining lease payments of approximately $83,000, discounted using the Company&#8217;s incremental borrowing rate of 7.5%, and (b) a right-of-use asset of approximately $60,000 which represents the lease liability of $80,000 adjusted for accrued rent of approximately $20,000.

The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.&nbsp;&nbsp;Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of the amendments on the financial statement disclosures. Since the amendments impact only disclosure requirements, the Company does not expect the amendments to have a material impact on the financial statements.</p>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>
