MIAMI, Nov. 04, 2025 (GLOBE NEWSWIRE) -- Longeveron Inc. (NASDAQ: LGVN), a clinical stage biotechnology company developing cellular therapies for life-threatening, rare pediatric and chronic aging-related conditions, today reported financial results for the quarter ended September 30, 2025 and provided a business update.

“I am excited to step in to lead Longeveron at this transformational period in both the Company’s history, and our advancement of laromestrocel,” said Than Powell, Interim Chief Executive Officer of Longeveron. “Longeveron has made significant progress advancing three stem cell therapy programs, with each step getting us closer to treating patients with life altering diseases. Our pivotal Phase 2b clinical trial evaluating laromestrocel as a potential treatment for HLHS, a rare pediatric congenital heart defect, is on track to deliver top-line trial results in the third quarter of 2026. If positive, this trial may be the foundation of the Company’s first BLA filing with the U.S. FDA. We believe our research is driving the next wave of medical innovation and Longeveron is well positioned to be an industry leader in stem cell clinical development and commercialization for the benefit of patients and their families.”

Development Programs Update
Longeveron’s investigational therapeutic candidate is laromestrocel (Lomecel-B^TM), a proprietary, scalable, allogeneic cellular therapy being evaluated in multiple indications.

Hypoplastic Left Heart Syndrome (HLHS) – a rare pediatric congenital heart birth defect in which the left ventricle (one of the pumping chambers of the heart) is either severely underdeveloped or missing.

• Pivotal Phase 2b clinical trial (ELPIS II) evaluating laromestrocel as a potential adjunct therapy for HLHS achieved full enrollment of 40 pediatric patients in June 2025.
• Top-line trial results are anticipated in the third quarter of 2026, after the final follow-up at 12-months.
• Laromestrocel Biological License Application (BLA) submission for full approval for HLHS, if ELPIS II results demonstrate sufficient evidence of efficacy, now anticipated in 2027 rather than late 2026 based on operational decisions to extend the cash runway for delivery of ELPIS II study results and to optimize manufacturing spend.
• ELPIS II is being conducted in collaboration with the National Heart, Lung, and Blood Institute (NHLBI) through grants from the National Institutes of Health (NIH).
• ELPIS II builds on the positive clinical results of ELPIS I, in which children in the trial experienced 100% transplant-free survival up to five years of age after receiving laromestrocel compared to approximate 20% mortality rate observed from historical control data.
• The FDA has granted laromestrocel Orphan Drug designation, Fast Track designation, and Rare Pediatric Disease designation for the treatment of HLHS.

Alzheimer’s disease (AD) – a neurodegenerative disorder that leads to progressive memory loss and death and currently has very limited therapeutic options.

• Results from the Phase 2a clinical trial (CLEAR MIND), which support the therapeutic potential of laromestrocel in the treatment of mild Alzheimer’s disease and provided evidence-based support for further clinical development, were published in the peer reviewed journal Nature Medicine in March 2025.
• Positive Type B meeting with FDA regarding pathway to BLA submission for laromestrocel in Alzheimer’s disease held in March 2025 with alignment reached on proposed trial study design, population and endpoints for a single, pivotal Phase 2/3 clinical trial that, if positive, would be acceptable for BLA submission for Alzheimer’s disease.
• The FDA has granted laromestrocel both Regenerative Medicine Advanced Therapy (RMAT) designation and Fast Track designation for the treatment of mild Alzheimer’s disease.
• The Company is seeking to forge strategic collaborations and/or partnerships for the advancement of laromestrocel in addressing AD.

Pediatric Dilated Cardiomyopathy (DCM) – a rare pediatric cardiovascular disease in which the muscles in one or more of the heart chambers become enlarged or stretched (dilated), with nearly 40% of children with DCM requiring a heart transplant or dying within two years of diagnosis.

• In July 2025, the FDA approved Longeveron’s Investigational New Drug (IND) application for its stem cell therapy laromestrocel as a potential treatment for pediatric dilated cardiomyopathy (DCM). The accepted IND application provides for moving directly to a single Phase 2 pivotal registration clinical trial.
• The Company currently anticipates initiation of the pivotal Phase 2 clinical trial in 2026, subject to obtaining necessary financing.

Corporate Updates

• In July, the Company announced the licensing of a new, composition of matter patent protected, stem cell technology from the University of Miami for unique induced pluripotent derived cardiomyogenic cells that have widespread therapeutic indications for heart diseases.
• In August, the Company completed a public offering, raising approximately $5.0 million, with up to an additional $12.5 million of potential aggregate gross proceeds upon the exercise in full of short-term warrants.
• In September, the Company announced key leadership updates with Than Powell being appointed Interim Chief Executive Officer, and Dr. Joshua Hare being appointed Executive Chairman of the Board of Directors.
• In October, the Company announced that George Paletta, Jr., MD, MBA, has been elected to the Longeveron Board of Directors. Dr. Paletta is a nationally and internationally recognized orthopedic surgeon and the head team doctor for the St. Louis Cardinals. Dr. Paletta is a developer of ambulatory surgical centers (ASCs), and has participated in the selling of two ASCs with deal values totaling almost $1 billion.

Third Quarter 2025 Summary Financial Results

• Revenues: Revenues for the nine months ended September 30, 2025 and 2024 were $0.8 million and $1.8 million, respectively. This represents a decrease of $1.0 million, or 53% in 2025 compared to 2024, driven primarily by a decreased participant demand for our Bahamas Registry Trial and reduced demand for contract manufacturing services from our third-party client. Clinical trial revenue, which is derived from the Bahamas Registry Trial, for the nine months ended September 30, 2025 and 2024 was $0.7 million and $1.0 million, respectively. Clinical trial revenue for the nine months ended September 30, 2025 decreased by $0.3 million, or 36%, when compared to 2024 as a result of decreased participant demand. Contract manufacturing revenue for the nine months ended September 30, 2025 was $0.2 million from our manufacturing services contract, which is a decrease of $0.6 million, or 76% when compared to the $0.8 million in contract manufacturing revenue for the nine months ended September 30, 2024. This decrease was driven by a substantial reduction in activities under the Secretome Agreement; no additional manufacturing or development activities are planned, and the Company is now limited to performing stability testing and other contract testing services.
• Cost of Revenues and Gross Profit: Cost of revenues was $0.3 million and $0.4 million for the nine months ended September 30, 2025 and 2024, respectively. This resulted in a gross profit of approximately $0.5 million for the nine months ended September 30, 2025, a decrease of $0.9 million, or 60%, when compared with a gross profit of $1.4 million for 2024.
• General and Administrative Expenses: General and administrative expenses for the nine months ended September 30, 2025 increased to approximately $9.1 million, compared to $7.4 million for the same period in 2024. The increase of approximately $1.7 million, or 22%, was primarily related to an increase in personnel and related costs in 2025, including increased severance and equity-based compensation.
• Research and Development Expenses: Research and development expenses for the nine months ended September 30, 2025 increased to approximately $9.3 million, from approximately $6.1 million for the same period in 2024. The increase of $3.2 million, or 52%, was primarily driven by a $1.8 million increase in personnel and related costs, including equity-based compensation, $1.2 million increase in supplies and costs associated with technology transfer, including non-clinical manufacturing batches that advance our readiness for future commercial production as part of our BLA-enabling efforts and a $0.2 million increase in amortization expense related to patent costs.
• Other Income (Expense): Other income for the nine months ended September 30, 2025 was $0.6 million, primarily consisting of $0.3 million received as a recipient of a Milestone 1 Award in the XPRIZE Healthspan competition and $ 0.3 million interest earned on money market funds. Other income for the nine months ended September 30, 2024 was $0.3 million as result of interest earned on money market funds and marketable securities.
• Net Loss: Net loss increased to approximately $17.3 million for the nine months ended September 30, 2025 from a net loss of $11.9 million for the same period in 2024. The increase in the net loss of $5.4 million, or 45%, was for the reasons outlined above.
• Cash and cash equivalents as of September 30, 2025 were $9.2 million. As a result of the recently completed financing in August of 2025, and continued focus on disciplined and efficient capital allocation focused on first to market indications, the Company currently anticipates its existing cash and cash equivalents will enable it to fund its operating expenses and capital expenditure requirements late into the first quarter of 2026, based on its current operating budget and cash flow forecast. The Company also has access to an At-The-Market (ATM) equity financing vehicle for the sale of up to $10.7 million aggregate market value of shares of the Company's Class A common stock. The Company intends to seek additional financing through capital raises, non-dilutive funding options, including grants and strategic partnerships across all indications. There can be no assurance the Company will be able to attain future financing at terms favorable to the Company or at all. In the event the Company is unable to attain the financing needed, it will need to materially revise its current operational plan.
