MIAMI, March 11, 2022 (GLOBE NEWSWIRE) -- Longeveron Inc. (NASDAQ: LGVN) (the “Company,” “Longeveron” or “we,” “us,” or “our”), a clinical stage biopharmaceutical company developing cellular therapies for chronic, aging-related and life-threatening conditions, today reported recent business highlights and key upcoming catalysts for 2022, and its financial results for the fourth quarter and full year 2021.

“For Longeveron, 2021 was a year defined by effective execution, successful financings, and significant progress across our robust Lomecel-B pipeline of clinical trials,” said Geoff Green, Chief Executive Officer at Longeveron. “Since our IPO in February of last year, important progress has been made in advancing Lomecel-B into next phase trials, including initiation of Phase 2 trials in Alzheimer’s and Hypoplastic Left Heart Syndrome (HLHS), with the latter receiving both Orphan Drug and Rare Pediatric Disease designations from the FDA. Additionally, we successfully closed a $20.5 million private placement of our common stock in the fourth quarter of 2021 to provide capital that we believe will be sufficient to support our ongoing research and operations into 2024. We anticipate 2022 to be another eventful year as we continue to work to demonstrate the potential therapeutic benefit of Lomecel-B across many life-threatening conditions.”

Business Update:

Lomecel-B for Alzheimer’s Disease:

• In January 2022, we opened enrollment for our Phase 2a clinical trial of Lomecel-B for the treatment of Alzheimer’s Disease. The Phase 2a study, supported by encouraging Phase 1 data announced in 2021, is designed to evaluate the safety of single and multiple administrations of two different doses of Lomecel-B compared to placebo in mild Alzheimer’s disease patients. Other endpoints include brain volumetry by MRI, biomarkers related to inflammatory and vascular systems, and various measures of cognitive function.   The first patient has already been treated (the study has a target enrollment of 48 patients), and we intend to activate up to 12 clinical sites to facilitate enrollment. We plan to provide updates on anticipated enrollment rates as additional sites are activated, and trial completion guidance. Further details about the trial design can be found on clinicaltrials.gov by entering trial identifier NCT05233774.
• We have submitted our Phase 1 results for publication in a peer-reviewed journal and anticipate acceptance and publication during the first half of 2022.

Lomecel-B for Hypoplastic Left Heart Syndrome (HLHS):

• The ELPIS II trial (Phase 2a) continues to enroll infants in the randomized, blinded 38 patient trial evaluating the safety and efficacy of Lomecel-B injection into the right ventricle of children born with HLHS who are undergoing Stage II reconstructive cardiac surgery. ELPIS II is being funded in part by a grant from the National Institute of Health’s National Heart, Lung, and Blood Institute (NHLBI; Grant number 1UG3HL148318), in collaboration with Longeveron, and is led by Principal Investigator Sunjay Kaushal, MD, PhD, Division Head, Cardiovascular-Thoracic Surgery, Ann and Robert H. Lurie Children’s Hospital of Chicago. All seven clinical sites have now been activated for screening and enrollment and additional sites are being considered.
• In fourth quarter 2021, the U.S. FDA granted Rare Pediatric Disease Designation and Orphan Drug Designation to Lomecel-B for the treatment of infants with HLHS. HLHS is a rare congenital heart defect affecting approximately 1,000 babies per year in the U.S.
• The Phase 1 (“ELPIS I”) results have been submitted for publication in a peer-reviewed journal and we anticipate acceptance and publication in 2022.
  
  

Lomecel-B for Aging Frailty:

• The planned Japanese Aging Frailty Phase 2 trial is currently on track to initiate in the first half of 2022. This is an investigator-initiated randomized, placebo-controlled, double-blind single infusion study being conducted by our clinical partners at the National Center for Geriatrics & Gerontology (NCGG; Nagoya), and Juntendo University Hospital (Tokyo).
• Results from the Phase 1/2 “HERA” Aging Frailty trial are expected to be announced in the first half of 2022. The HERA Trial is a multicenter, randomized, placebo-controlled study intended to evaluate safety, and to explore the effect Lomecel-B may have on biomarkers of immune system function in Aging Frailty subjects receiving the influenza vaccine, as well as other signs and symptoms of Aging Frailty.
• On January 12, 2022 Longeveron announced of the Lomecel-B Phase 2b Aging Frailty trial design in The Journal of Aging and Frailty titled: “The Design and Rationale of a Phase 2b, Randomized, Double-Blinded, and Placebo-Controlled Trial to Evaluate the Safety and Efficacy of Lomecel-B in Older Adults with Frailty.”
  
  

Lomecel-B for Acute Respiratory Distress Syndrome Due to COVID 19 Infection:

• Our Phase 1 trial continues to screen patients at three participating centers in the U.S. We expect enrollment to continue through 2022.
  
  

Board Expansion:

• On February 17, 2022 we announced the appointment of Todd Girolamo to our Board of Directors. Mr. Girolamo is a seasoned attorney and biopharmaceutical executive specializing in health-related products, currently serving as Chief Legal Officer, Senior Vice President of Corporate Development and Corporate Secretary for Caladrius Biosciences, Inc.
  
  

Financial Results for Full Year and Fourth Quarter Ended December 31, 2021

Revenue: Revenue in the fourth quarter 2021 was $0.2 million compared to $1.2 million in the same period in 2020. The difference was due to a decrease in clinical trial revenue and grant revenue, as follows:

• Clinical trial revenue, which derives from our Bahamas Registry Trial, was $0.2 million in the fourth quarter of 2021 compared to $0.5 million in the same period in 2020, a decrease of $0.3 million, or 68%. Continued COVID-19-related travel concerns have negatively impacted Registry Trial revenue.
  
  
• Fourth quarter 2021 grant revenue was less than $0.1 million compared to $0.7 million in the same period in 2020, a decrease of $0.6 million, or 93%. The decrease in grant revenue is due to the completion of several grant-funded clinical trials and associated exhaustion of grant revenue.  
  
  

Revenue for full year 2021 was $1.3 million compared to $5.6 million in 2020. Clinical trial revenue was $0.7 million for 2021 compared to $1.3 million for 2020, a decrease of $0.6 million, or 46%. Grant revenue was $0.6 million for 2021 compared to $4.3 million for 2020, a decrease of $3.7 million, or 86%. The difference was due to same reasons outlined above with respect to our Bahamas Registry Trial and completion of grant-funded clinical trials.

R&D Expenses: Research and development expenses in the fourth quarter of 2021 were $1.7 million compared to $1.2 million for the same period in 2020. The increase of $0.5 million, or 51%, was primarily due to an increase in research and development expenses related to the completion of clinical trials that were not reimbursable by grants. R&D Expenses for full year 2021 were $7.1 million compared to $2.7 million for 2020. The increase of $4.4 million, or 165% was primarily due to an increase in research and development expenses related to the completion of clinical trials that were not reimbursable by grants; including $2.2 million of equity-based compensation recorded for Restricted Stock Units (“RSUs”) and stock options granted during the year.

G&A Expenses: General and administrative expenses in the fourth quarter of 2021 were $2.3 million compared to $0.7 million for the same period in 2020. The increase of approximately $1.6 million, or 225%, was primarily related to an increase in compensation, insurance and professional expenses incurred during the current period; including $0.4 million of equity-based compensation recorded for RSUs and stock options granted during the quarter. G&A Expenses for full year 2021 were $10.7 million compared to $2.7 million for 2020. The increase of $8.0 million, or 293% was primarily due to an increase in compensation, insurance and professional expenses incurred during the current period; as well as $1.1 million in investor relation costs, and including $4.6 million of equity-based compensation expenses recorded during the year.

Net Loss: Net loss was $4.1 million in the fourth quarter of 2021 compared to $1.4 million for the same period in 2020. Net loss for full year 2021 was $17.0 million compared to $3.7 million in 2020.

Per Share: Net loss per share was $0.20 in the fourth quarter of 2021 compared to $0.08 for the same period in 2020. Net loss per share for full year 2021 was $0.90 compared to $0.23 in 2020.

Cash and Short Term Investments: Cash and short-term investments was $35.0 million compared to $0.8 million as of December 31, 2021 and 2020, respectively. The increase in cash period over period was the result of proceeds received from our initial public offering in February 2021 and our subsequent private placement offering in December 2021.

Financial Outlook

Based on the Company’s current operating plan and financial resources, we believe that our existing cash and short-term investments will be sufficient to cover expenses and capital requirements into 2024.
