MIAMI, May 08, 2025 (GLOBE NEWSWIRE) -- Longeveron Inc. (NASDAQ: LGVN), a clinical stage regenerative medicine biotechnology company developing cellular therapies for life-threatening and chronic aging-related conditions, today reported financial results for the quarter ended March 31, 2025 and provided a business update.

“In the first quarter, we made notable progress advancing the development of our stem cell therapy, laromestrocel,” said Wa’el Hashad, Chief Executive Officer of Longeveron. “We have three critical organizational priorities in 2025. First, supporting the completion of ELPIS II, our pivotal Phase 2b clinical trial evaluating laromestrocel as a potential treatment for HLHS. Second, following FDA confirmation that ELPIS II is pivotal, we are focused on organizational readiness for a potential BLA filing for HLHS in 2026. Our goal is to substantially advance our BLA readiness this year ahead of data readout to potentially shorten the timeline to BLA submission. Lastly, we plan to leverage the strength of our Phase 2 data and clarity on the clinical pathway to a potential BLA for Alzheimer’s disease to engage with potential partners that could fund and accelerate the development of laromestrocel in this indication. Our success executing on our strategic plan in an efficient, high-quality manner continues to position Longeveron as a leader in stem cell therapy research and, potentially, commercialization of cellular therapeutics.”

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

In February 2025, the International Nonproprietary Names (INN) Expert Committee of the World Health Organization (WHO) approved “laromestrocel” as the non-proprietary name of Lomecel-B™.

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 is currently enrolling 38 pediatric patients at twelve premiere infant and children’s treatment institutions across the country. ELPIS II has reached approximately 95% enrollment and is currently anticipated to complete enrollment in the second quarter of 2025.
• In August 2024, the U.S. Food and Drug Administration (FDA) confirmed that ELPIS II is a pivotal trial and, if it demonstrates sufficient evidence of efficacy, it would be acceptable for a Biologics License Application (BLA) submission for full traditional approval for HLHS.
• 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.
  

First Quarter 2025 Summary Financial Results

• Revenues: Revenues for the three months ended March 31, 2025 and 2024 were $0.4 million and $0.5 million, respectively. This represents a decrease of $0.1 million, or 30%, in 2025 compared to 2024, driven primarily by a decreased participant demand for our Bahamas Registry Trial, partially offset by an increase of our manufacturing services contract revenue. Clinical trial revenue from the Bahamas Registry Trial for the three months ended March 31, 2025 and 2024 was $0.3 million and $0.5 million, respectively, reflecting a decrease of $0.2 million, or 50%, due to decreased participant demand. Contract manufacturing revenue for the three months ended March 31, 2025 and 2024 was $0.1 million and $33,000, reflecting an increase of approximately $0.1 million, or 270%, due to increased activity from our manufacturing services contract.
• Cost of Revenues and Gross Profit: Cost of revenues was $0.1 million and $0.2 million for the three months ended March 31, 2025 and 2024. This resulted in a Gross Profit of approximately $0.3 million for each of the three months ended March 31, 2025 and 2024, reflecting a flat year-over-year comparison.
• General and Administrative Expenses: General and administrative expenses for the three months ended March 31, 2025 increased to approximately $2.9 million compared to $2.2 million for the same period in 2024. The increase of approximately $0.7 million, or 34%, was primarily related to an increase in personnel and related costs, including equity-based compensation.
• Research and Development Expenses: Research and development expenses for the three months ended March 31, 2025 increased to approximately $2.5 million from approximately $2.2 million for the same period in 2024. The increase of $0.3 million, or 13%, was primarily driven by a $0.4 million increase in personnel and related costs, including equity-based compensation, a $0.2 million increase in amortization expense related to patent costs and a $0.1 million increase in supplies costs, partially offset by a $0.4 million decrease in clinical trial expense, primarily driven by the absence of costs related to the now-completed CLEAR MIND Alzheimer’s disease clinical trial, as well as the discontinuation of activities related to the Aging-related frailty clinical trial following our decision to discontinue trial activities in Japan.
• Other Income, net: Other income for the three months ended March 31, 2025 was $0.2 million, primarily consisting of interest earned on money market funds. Other income for the three months ended March 31, 2024 was less than $0.1 million.
• Net Loss: Net loss increased to approximately $5.0 million for the three months ended March 31, 2025 from $4.0 million for the same period in 2024. This increase of $1.0 million, or 23%, was due to the factors outlined above.
• Cash and cash equivalents as of March 31, 2025 were $14.3 million. 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 third quarter of 2025 based on its current operating budget and cash flow forecast. Following a successful Type C meeting with the FDA in August 2024 with respect to the HLHS regulatory pathway, the Company has begun ramping up its BLA enabling activities. The Company currently anticipates a potential BLA filing with the FDA in 2026 if the current ELPIS II trial in HLHS is successful. The Company's operating expenses and capital expenditure requirements will increase throughout calendar 2025 as a result of these activities, including CMC (Chemistry, Manufacturing, and Controls) and manufacturing readiness. The Company expects that its current operating plan will require increased spending and additional capital investments to support these initiatives and intends to seek additional financing/capital raises/non-dilutive funding options to support them. Additionally, following a positive Type B meeting with the U.S. FDA in March 2025 with respect to the Alzheimer's disease regulatory pathway, the Company is focused on seeking partnership opportunities and/or non-dilutive funding for the Alzheimer’s disease program, including a proposed single, pivotal, seamless adaptive Phase 2/3 clinical trial.
