Our current product candidates include CLBS119, an emergent CD34+ stem cell therapy responding to the COVID-19 pandemic and the potentially permanent damage it inflicts on the lungs of many patients, as well as three other developmental treatments for ischemic diseases based on our CD34+ cell therapy platform: CLBS12, recipient of SAKIGAKE designation and eligible for early conditional approval in Japan for the treatment of critical limb ischemia ("CLI") based on the results of an ongoing clinical trial; CLBS16, the subject of a recently completed positive Phase 2 clinical trial in the U.S. for the treatment of coronary microvascular dysfunction ("CMD"); and CLBS14, a Regenerative Medicine Advanced Therapy ("RMAT") designated therapy for which we have finalized with the U.S. Food and Drug Administration (the "FDA") a protocol for a Phase 3 confirmatory trial in subjects with no-option refractory disabling angina ("NORDA").</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Ischemic Repair (CD34 Cell Technology)</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The CD34+ cell was discovered as a result of the deliberate search for a stem cell capable of stimulating the development and/or repair of blood vessels. All tissues in the body maintain their function by replacing cells over time. In addition to the maintenance function, the body must also be capable of building new blood vessels after injury. A CD34+ cell is a stem cell that has the ability to stimulate new blood vessel formation. No other native cell discovered to date has demonstrated this same capability.</font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our proprietary CD34+ cell technology has led to the development of therapeutic product candidates designed to address diseases and conditions caused by ischemia. Ischemia occurs when the supply of oxygenated blood to healthy tissue is restricted. Through the administration of CD34+ cells, we seek to promote the development and formation of new microvasculature and thereby increase blood flow to the impacted area. We believe that a number of conditions caused by underlying ischemic injury can be improved through our CD34+ cell technology, including but not limited to, CLI, CMD, NORDA and COVID-19 induced lung damage.</font></div><div style="text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">CLBS119 for Treatment of COVID -19 Induced Lung Damage</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">COVID-19 appears to damage the vasculature of the lungs and we believe that repair of that vasculature will prove necessary for patients to achieve a full recovery. Survivors of COVID-19 often remain debilitated even after leaving the hospital due to the damage caused to their lungs, and while many developmental therapies responding to the COVID-19 pandemic are appropriately targeting the SARS-CoV-2 virus itself or the symptoms of the acute phase of the illness, we are aware of no therapy that has demonstrated the ability to repair COVID-19 induced lung damage. With consistent clinical and pre-clinical evidence that CD34+ cells can repair multiple organs, including models of severe lung inflammation, we sought and received FDA authorization for our investigational new drug (&#8220;IND&#8221;) application for the study of CLBS119, a CD34+ cell therapy for repair of COVID-19 induced lung damage. The planned study will target patients with severe SARS-CoV-2 infection who, after ventilatory support due to respiratory failure, had otherwise recovered but remained debilitated due to persistent pulmonary damage.</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">CLBS12 for Treatment of Critical Limb Ischemia</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our open-label, registration-eligible study of CLBS12 in Japan for the treatment of critical limb ischemia ("CLI"), a disease with no currently available approved therapy and a higher mortality rate than all cancers except that of lung cancer, has shown strong results to date. The initial responses observed in the subjects who have reached an endpoint in this open label study are consistent with a positive therapeutic effect and safety profile as reported by previously published clinical trials in Japan.

That study, titled ESCaPE-CMD, was a Phase 2 proof-of-concept study that enrolled patients at the Mayo Clinic in Rochester, MN and Cedars-Sinai Medical Center in Los Angeles, CA. In June 2019, we announced the completion of enrollment in this study. Results of the first 17 of 20 patients enrolled in this trial who reached 6-month follow-up were presented as a rapid fire oral presentation on November 16, 2019 at the annual meeting of the American Heart Association in Philadelphia, PA by one of the principal investigators, Dr. Noel Bairey Merz, FACC, FAHA, FESC, the director of the Barbra Streisand Women's Heart Center at Cedars-Sinai in Los Angeles, CA. That data set showed a positive therapeutic effect with a statistically significant improvement in angina frequency, coronary flow reserve, Canadian Cardiovascular Society Angina Class and Seattle Questionnaire score, as well as an acceptable safety profile. The full data from that study was presented at the SCAI 2020 Scientific Sessions Virtual Conference on May 14, 2020 and we now expect to initiate the next CMD trial, a Phase 2b study, in the fall of 2020.</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">CLBS14 for Treatment of No Option Refractory Disabling Angina (NORDA)</font></div><div style="text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We acquired the rights to data and regulatory filings for a CD34+ cell therapy program for refractory angina that had been advanced to Phase 3 by a previous sponsor.</font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Based on the clinical evidence from the completed studies that a single administration of CLBS14 reduces mortality, improves angina and increases exercise capacity in patients with otherwise untreatable angina, this product received Regenerative Medicine Advanced Therapy (&#8220;RMAT&#8221;) designation from the FDA. Working closely with the FDA, we have finalized the design of a confirmatory Phase 3 trial which, in combination with previously filed Phase 1, 2 and 3 data, will be considered for the registration of CLBS14. Notably, this study design includes a 6-month primary endpoint and, with the benefit of the RMAT designation, the biologics license application ("BLA"), once submitted, should receive a 6-month review.

The registration of the shares of common stock issuable to the selling stockholders upon the exercise of the Warrants does not necessarily mean that the selling stockholders will sell all or any of such shares, but the number of shares and percentages set forth in the final two columns below assume that all shares of common stock being offered by the selling stockholders are sold.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">&#160;</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The table is based on information supplied to us by the selling stockholders, with beneficial ownership and percentage ownership determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to shares of stock. This information does not necessarily indicate beneficial ownership for any other purpose. In computing the number of shares beneficially owned by a selling stockholder and the percentage ownership of that selling stockholder, shares of common stock subject to warrants held by that selling stockholder that are exercisable within 60 days after June 15, 2020, are deemed outstanding. Such shares, however, are not deemed outstanding for the purposes of computing the percentage ownership of any other person.

Such shares are issuable to the selling stockholders upon the exercise of the Warrants. The Warrants are immediately exercisable upon issuance and expire five and one-half (5.5) years from their initial date of issuance. The April 2020 Warrants have an exercise price of $2.25 per share and the May 2020 Warrants have an exercise price of $2.0625 per share. See &#8220;Prospectus Summary -Registered Direct Offerings of Common Stock and Concurrent Private Placements of Warrants&#8221; above for a complete description of the Warrants. The selling stockholders may sell all, some or none of their shares in this offering, but the number of shares and percentages set forth in the final two columns below assume that all shares of common stock being offered by the selling stockholders are sold.

We expect the existence of this provision to have an anti-takeover effect with respect to transactions our Board of Directors does not approve in advance.

It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Transfer Agent and Registrar</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">&#160;</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The transfer agent and registrar for our common stock is Continental Stock Transfer &amp; Trust Company, 17 Battery Place, New York, New York 1004.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">&#160;</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Nasdaq Capital Market Listing</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">&#160;</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our common stock is publicly traded on the Nasdaq Capital Market under the symbol &#8220;CLBS.&#8221;</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">13</font></div></div><hr style="page-break-after:always"><div><a name="s06AFCCD6B2D95FD1AC783313F8D51C7F"></a></div><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">LEGAL MATTERS</font></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">&#160;</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., New York, New York, will pass upon the validity of the shares of common stock being offered by this prospectus.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">&#160;</font></div><div><a name="s4CBFF2068B9950A386012285AD8ED34C"></a></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">EXPERTS</font></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">&#160;</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The audited financial statements incorporated by reference in this prospectus and elsewhere in the registration statement have been so incorporated by reference in reliance upon the report of Grant Thornton LLP, independent registered public accountants, upon the authority of said firm as experts in accounting and auditing.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><a name="sF249CA82D72B56CFA008E031DB9BC48C"></a></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">WHERE YOU CAN FIND MORE INFORMATION</font></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">&#160;</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We file annual, quarterly and other periodic reports, proxy statements and other information with the SEC.
