Dec. 31, 2023
Accounting Policies [Abstract] |
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”), of the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of the Company and CalciMedica Subsidiary, Inc. for the years ended December 31, 2023 and 2022. All intercompany accounts and transactions have been eliminated in consolidation. Since Private CalciMedica was determined to be the accounting acquirer in connection with the Merger, for periods prior to the Merger, the consolidated financial statements were prepared on a stand-alone basis for Private CalciMedica and did not include the combined entities activity or financial position. Subsequent to the Merger, the consolidated financial statements as of and for the year ended December 31, 2023 include Graybug’s activity from March 21, 2023 through December 31, 2023, and assets and liabilities at their acquisition date fair value. Historical share and per share figures of Private CalciMedica have been retroactively restated based on the merger exchange ratio of 0.0288.
Use of Estimates | Use of Estimates The preparation of the Company’s consolidated financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the Company’s consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to accruals for research and development expenses, valuation of warrants, valuation of convertible promissory notes and valuation of equity awards. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.
Concentration of Credit Risk and other Risks and Uncertainties | Concentration of Credit Risk and other Risks and Uncertainties Financial instruments, which potentially subject the Company to concentration of risk, consist principally of cash and cash equivalents. The Company’s cash is deposited with major federally insured U.S. financial institutions. The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts or other hedging arrangements. The Company is dependent on contract manufacturing organizations (“CMO”) to supply products for research and development of its product candidates, including preclinical and clinical studies, and for commercialization of its product candidates, if approved. The Company’s development programs could be adversely affected by any significant interruption in CMO’s operations or by a significant interruption in the supply of active pharmaceutical ingredients and other components. Products developed by the Company require approval from the FDA or other international regulatory agencies prior to commercial sales. There can be no assurance the Company’s product candidates will receive the necessary approvals. If the Company is denied approvals, approvals are delayed, or the Company is unable to maintain approvals received, such events could have a materially adverse impact on the Company.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of readily available cash in checking accounts, money market funds and commercial paper. The Company considers all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents.
Short-term Investments | Short-term Investments The Company invests excess cash in commercial paper and U.S government sponsored entities - mortgage-backed securities. These investments are included in short-term investments on the balance sheet, classified as available-for-sale and reported at fair value with unrealized gains and losses included in accumulated other comprehensive (loss)/gain, net. Realized gains and losses on the sale of these securities are recognized in net loss.
Segment Information | Segment Information The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The financial information is regularly reviewed by the chief operating decision maker (“CODM”), in deciding how to allocate resources. The Company’s CODM is its chief executive officer. The Company’s singular focus is on developing highly selective calcium release-activated calcium channel inhibitors to improve outcomes for patients with acute inflammatory indications. No significant revenue has been generated since inception, and all tangible assets are held in the United States.
Fair Value Option | Fair Value Option As permitted under ASC 825, Financial Instruments, the Company has elected the fair value option to account for its convertible promissory notes due to certain embedded features within the notes. The Company recognizes the convertible promissory notes at fair value with changes in fair value recognized in the consolidated statements of operations located on the change in fair value of financial instruments line item. Changes in fair value as a result of the Company’s own credit risk is reflected in other income (expense) in the consolidated statements of operations. As a result of applying the fair value option, direct costs and fees related to the convertible promissory notes were expensed as incurred and not deferred.
Property and Equipment | Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets (generally three to five years) and consist of manufacturing and lab equipment, furniture, computers and phones. Repairs and maintenance costs are charged to expense as incurred. Depreciation expense recognized for the years ended December 31, 2023 and 2022 was $58,000 and $52,000, respectively.
Long-lived assets | Long-lived Assets Long-lived assets consist primarily of property and equipment. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset is not recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. The Company did no t recognize any impairment losses for the years ended December 31, 2023 and 2022.
Leases | Leases The Company leases office space with an original lease term of twelve months and does no t have a right-of-use asset or lease liability recorded. The Company's policy is not to record leases with an original term of twelve months or less on the consolidated balance sheets. The Company recognizes lease expense for this short-term lease on a straight-line basis over the term of the lease. The lease is accounted for under ASC 842, Leases, and has been classified as an operating lease. Rent expense recognized for the years ended December 31, 2023 and 2022 was $274,000 and $221,000, respectively.
Research and Development Costs | Research and Development Costs Research and development costs consist primarily of salaries, payroll taxes, employee benefits and stock-based compensation for those individuals involved in ongoing research and development efforts, as well as fees paid to consultants, external research fees, license fees paid to third parties for use of their intellectual property, laboratory supplies and development of compound materials, associated overhead expenses and facilities and depreciation costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. All research and development costs are expensed as incurred. The Company estimates preclinical studies and clinical trial expenses based on the services performed pursuant to contracts with research institutions and clinical research organizations that conduct and manage preclinical studies and clinical trials on the Company’s behalf. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort to be expended in each period. These estimates are based on communications with the third-party service providers, and on information available at each balance sheet date. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly. The estimates are trued up to reflect the best information available at the time of the financial statement issuance. Although the Company does not expect its estimates to be materially different from amounts actually incurred, the Company’s estimate of the status and timing of services performed relative to the actual status and timing of services performed may vary.
General and Administrative Costs | General and Administrative Costs General and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation, related to executive, finance, business development, legal, human resources and support functions, including professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance.
Patent Costs | Patent Costs Costs related to filing and pursuing patent applications are expensed as incurred since recoverability of such expenditures is uncertain.
Deferred Offering Costs | Deferred Offering Costs The Company capitalizes costs that are directly associated with equity financings until such financings are consummated at which time such costs are recorded against the gross proceeds of the offering. Should an in-process equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the statements of operations and comprehensive loss. Private CalciMedica had deferred offering costs capitalized as of December 31, 2022 for the Merger of $1.4 million. As of December 31, 2023, the Company has deferred costs associated with its at-the-market offering of $0.4 million.
Warrant Liability | Warrant Liability Private CalciMedica has issued various freestanding warrants to purchase shares of its convertible preferred stock. Prior to the Merger, Private CalciMedica adjusted the carrying value of such convertible preferred stock warrants to the estimated fair value at each reporting date, with any related increases or decreases in the fair value being recorded within other income (expense) in the consolidated statements of operations and comprehensive loss. Pursuant to the Merger Agreement, the Series C convertible preferred stock warrants became warrants to purchase shares of the combined company's common stock. As a result of the Merger, the warrants no longer meet the requirements for liability accounting and, as such, Private CalciMedica adjusted the value of the warrants to the estimated fair value as of the Merger date and reclassified them to stockholders' equity (deficit).
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation expense represents the cost of the grant date fair value of employee stock options recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. Private CalciMedica estimates the fair value of stock option grants using the Black-Scholes option pricing model (“Black-Scholes”). Forfeitures are recognized as a reduction of stock-based compensation expense as they occur. Equity-based compensation expense is classified in the statements of operations in the same manner in which the award recipients’ payroll costs are classified or in which the award recipients’ service payments are classified. The fair value of each stock option grant is estimated on the date of grant using Black Scholes. The following summarizes the inputs used: Fair Value of Common Stock Prior to the Merger, there was no public market for Private CalciMedica’s common stock. The fair value of the shares of common stock underlying Private CalciMedica’s share-based awards was estimated on each grant date by Private CalciMedica’s board of directors. To determine the fair value of Private CalciMedica’s common stock underlying option grants, the board of directors considered, among other things, input from management and valuations of Private CalciMedica's common stock prepared by third-party valuation firms. Post Merger, CalciMedica uses the closing stock price the day prior to the grant date for the fair value. Risk-Free Interest Rate The risk-free interest ra te is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities similar to the expected term of the awards. Expected Volatility Prior to the merger, since Private CalciMedica did not have publicly traded equity securities, the volatility of the options has been estimated using peer group volatility information. Post Merger, CalciMedica uses an average volatility for comparable publicly-traded biopharmaceutical companies over a period equal to the expected term of the stock award grant as CalciMedica does not yet have sufficient historical trading history for its own stock. CalciMedica will continue to apply this method until a sufficient amount of historical information over a period equal to the expected term of the stock-based awards becomes available. Expected Term CalciMedica used the simplified method to calc ulate the expected term for all grants during all periods, which is based on the midpoint between the vesting date and the end of the contractual term. Expected Dividend Yield CalciMedica has never paid and has no present intention to pay cash dividends.
Income Taxes | Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability.
Comprehensive Loss | Comprehensive Loss Comprehensive loss is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources which are excluded from net loss. The Company’s only element of other comprehensive loss is unrealized gains and losses on marketable securities.
Related Party Transactions | Related Party Transactions The Company’s board of directors reviews and approves transactions with directors, officers and holders of 5% or more of its voting securities and their affiliates, each a related party. The material facts as to the related party’s relationship or interest in the transaction are disclosed to its board of directors prior to their consideration of such transaction, and the transaction is not considered approved by its board of directors unless a majority of the directors who are not interested in the transaction approve the transaction. Beginning in November 2020, Private CalciMedica has paid consulting fees monthly to a consulting firm affiliated with the Company’s interim chief financial officer in connection with its consulting agreement. CalciMedica recorded expense of $521,000 and $223,000 during years ended December 31, 2023 and 2022, respectively.
Net Loss Per Share | Net Loss Per Share Net loss is equivalent to net loss attributable to common stockholders for all periods presented. Basic net loss per share is computed using the weighted average number of shares of common stock outstanding during the period. The Company calculates diluted net loss per share using the more dilutive of the (1) treasury stock method, if-converted method, or contingently issuable share method, as applicable, or (2) the two-class method. For warrants, the calculation of diluted net loss per share requires that, to the extent the average fair value of the underlying shares for the reporting period exceeds the exercise price of the warrants and the presumed exercise of such securities are dilutive to net loss per share for the period, adjustments to net loss used in the calculation are required to remove the change in fair value of the warrants for the period. In all periods presented, the Company’s outstanding preferred stock, stock options, preferred, common and convertible promissory note warrants, and outstanding convertible promissory notes were excluded from the calculation of loss per share because the effect would be antidilutive. Accordingly, in periods in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. This update is effective for the Company beginning January 1, 2023. The Company adopted this ASU as of January 1, 2023, which did not have an impact on its consolidated financial statements and related disclosures. In August 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). The ASU provides guidance that simplified the accounting for certain financial instruments with characteristics of liabilities and equity. The new guidance reduced the number of accounting models for convertible debt and convertible preferred stock instruments and made certain disclosure amendments intended to improve the information provided to users. The guidance also amended the derivative guidance for the “own stock” scope exception, which exempts qualifying instruments from being accounted for as derivatives if certain criteria are met. Finally, the standard changed the way certain convertible instruments are treated when calculating earnings per share. This guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company is currently assessing the impact that this guidance will have on its consolidated financial statements.
