Longeveron Inc. (LGVN) is a clinical-stage regenerative medicine biotechnology company developing groundbreaking cellular therapies to address life-threatening and chronic aging-related conditions. The company's lead investigational product, Lomecel-B (now approved as "laromestrocel" by the World Health Organization), is a proprietary, scalable, allogeneic cell therapy derived from the bone marrow of young, healthy adult donors. Lomecel-B has demonstrated promising results across multiple clinical trials, positioning Longeveron as a pioneer in the rapidly evolving field of regenerative medicine.
Longeveron's Genesis and Early Progress Longeveron was formed as a Delaware limited liability company on October 9, 2014, and was authorized to transact business in Florida on December 15, 2014. On February 12, 2021, Longeveron, LLC converted from a Delaware limited liability company to a Delaware corporation, Longeveron Inc. The company operates out of its leased facilities in Miami, Florida, focusing on developing cellular therapies for specific aging-related and life-threatening conditions.
Since its inception, Longeveron has primarily been engaged in organizational activities, including raising capital, and research and development activities. The company has not yet achieved profitable operations or generated positive cash flows from operations. Longeveron has incurred recurring losses from operations since its inception, including a net loss of $15.4 million for the nine months ended September 30, 2023. As of September 30, 2024, the company had an accumulated deficit of $105.5 million.
Longeveron has financed its operations through various means, including its IPO, public and privately placed equity financings, grant awards, and fees generated from the Bahamas Registry Trial and contract manufacturing services. From inception through December 31, 2023, the company has been awarded approximately $11.9 million in governmental and non-profit association grants, which have been used to fund its clinical trials, research and development, production and overhead.
It's important to note that Longeveron's product candidates are currently in development, and there can be no assurance that the company's research and development will be successfully completed, that adequate protection for its intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval, or that any approved products will be commercially viable.
Tackling Rare and Life-Threatening Conditions Hypoplastic Left Heart Syndrome (HLHS) is a rare and devastating congenital heart defect that affects newborns, leaving the left side of the heart severely underdeveloped. Without immediate and complex surgical interventions, HLHS is fatal. Longeveron's HLHS program has received Orphan Drug Designation, Rare Pediatric Disease Designation, and Fast Track Designation from the U.S. Food and Drug Administration (FDA), underscoring the significant unmet need and the potential of Lomecel-B to address this devastating condition.
Longeveron is currently conducting a pivotal Phase 2b clinical trial, ELPIS II, to evaluate the safety and efficacy of Lomecel-B as an adjunct therapy to the standard-of-care surgical treatment for HLHS. The trial has achieved more than 90% enrollment, and the company expects to complete enrollment by the end of the second quarter of 2025. If the results from ELPIS II are positive, Longeveron plans to initiate a rolling Biological License Application (BLA) submission with the FDA in 2026, potentially paving the way for the first approved regenerative therapy for HLHS.
The HLHS program is based on promising results from the Phase 1 open-label study (ELPIS I) that supported the safety and tolerability of Lomecel-B when directly injected into the functional right ventricle during the second-stage standard-of-care surgery. Preliminary data revealed suggestions of either improvement or prevention of deterioration in several indices of right ventricular function over one year following surgery.
In addition to its HLHS program, Longeveron is also making significant strides in the treatment of Alzheimer's disease (AD), a devastating neurodegenerative condition that affects millions of Americans. The company's Phase 2a CLEAR MIND trial, which evaluated the safety and efficacy of Lomecel-B in patients with mild AD, delivered promising results. The trial met its primary safety endpoint and demonstrated statistically significant improvements in secondary efficacy endpoints, including cognitive function and brain volume preservation, compared to placebo.
Specifically, the CLEAR MIND trial showed no incidence of hypersensitivity or infusion-related reactions, no cases of amyloid-related imaging abnormalities (ARIA), and all Lomecel-B treatment groups met the safety primary endpoint. Additionally, the study indicated potential preservation of brain volumes in some AD-related areas of the brain, with a 49% reduction in brain volume loss and improvement in cerebral blood flow.
Based on these positive findings, the FDA has granted Lomecel-B both Regenerative Medicine Advanced Therapy (RMAT) designation and Fast Track designation for the treatment of mild AD, making it the first cellular therapy candidate to receive these designations for this indication. Longeveron is now preparing to meet with the FDA in the first quarter of 2025 to discuss the future clinical and regulatory strategy for advancing Lomecel-B in the treatment of Alzheimer's disease.
Diversified Pipeline and Operational Advancements While Longeveron's HLHS and AD programs are its primary focus, the company has also explored the potential of Lomecel-B in addressing aging-related frailty, a condition that disproportionately increases the risk of poor clinical outcomes from disease and injury in the elderly population. Although the company has discontinued its clinical trial activities in Japan for this indication, it continues to enroll patients in registry trials in The Bahamas to gather real-world data on the potential benefits of Lomecel-B for frailty and cognitive impairment.
Longeveron has previously completed two U.S. clinical trials under FDA IND 016644 to evaluate Lomecel-B for Aging-related Frailty. One was a multicenter, randomized, placebo-controlled Phase 2b trial that showed a single infusion of Lomecel-B significantly improved 6-Minute Walk Test (6MWT) distance 9 months after infusion, and a dose-dependent increase in 6MWT distance 6 months after infusion. The second was a multicenter, randomized, placebo-controlled Phase 1/2 trial (HERA Trial) intended primarily to evaluate safety and explore the effect Lomecel-B may have on specific biomarkers of immune system function in older, frail individuals receiving the high dose influenza vaccine.
Operationally, Longeveron has made significant strides in bolstering its manufacturing capabilities to support the advancement of its clinical programs. In 2024, the company appointed Devin Blass as its Chief Technology Officer and Senior Vice President of Chemistry, Manufacturing, and Controls (CMC), underscoring the importance of building a robust and scalable manufacturing infrastructure to meet the anticipated demand for Lomecel-B.
Financial Performance and Outlook Longeveron's financial performance in 2024 showcased the company's ability to generate diversified revenue streams while maintaining disciplined cost management. For the full year 2024, the company reported total revenue of $2.4 million, a 237% increase compared to the previous year. This growth was primarily driven by increased participant demand for the company's Bahamas Registry Trials and the successful initiation of contract manufacturing services, which contributed $1 million in revenue.
Despite the company's focus on advancing its clinical programs, Longeveron was able to reduce its total operating expenses by 13% year-over-year, with a 16% decrease in general and administrative expenses and a 10% decrease in research and development expenses. This prudent cost management, combined with the revenue growth, contributed to a 25% reduction in net loss, which stood at $16 million for the full year 2024.
For the most recent quarter, Longeveron reported revenue of $0.8 million, a net loss of $4.4 million, operating cash flow (OCF) of -$3.4 million, and free cash flow (FCF) of -$3.5 million. The company's year-over-year revenue growth was an impressive 415%, primarily driven by increased participant demand for the Bahamas Registry Trial and the addition of a manufacturing services contract.
It's worth noting that Longeveron currently only sells in the United States market.
Liquidity and Capital Resources Looking ahead, Longeveron believes its existing cash and cash equivalents of $19.2 million as of December 31, 2024, will enable the company to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2025, based on its current operating budget and cash flow forecast. However, the company has started to ramp up its BLA-enabling activities for the HLHS program, which are expected to accelerate its operating expenses and capital investments in 2025. Longeveron intends to seek additional financing and non-dilutive funding options to support these activities and maintain its momentum in advancing Lomecel-B towards potential regulatory approvals and commercialization.
The company's financial position remains relatively strong, with a debt-to-equity ratio of 0.07, a current ratio of 7.60, and a quick ratio of 7.60. It's important to note that Longeveron does not have any available credit lines at present.
