MIAMI, June 04, 2026 (GLOBE NEWSWIRE) -- Longeveron Inc. (NASDAQ:LGVN), a clinical stage biotechnology company developing cellular therapy for life-threatening, rare pediatric and chronic aging-related conditions, today announced that the Company will participate in the BIO International Convention taking place June 22-25, 2026 at the San Diego Convention Center. Longeveron will present a Company and laromestrocel (LOMECEL-B^®) overview Wednesday, June 24th at 2:15pm PT in Theater 4.

Company representatives Stephen Willard, CEO, Dr. Joshua Hare, Founder, CSO and Executive Chairman, and Than Powell, Business Development, will host meetings with global pharmaceutical company executives to explore potential partnership and strategic opportunities for the Company's Hypoplastic Left Heart Syndrome (HLHS), Alzheimer's disease (AD), Pediatric Dilated Cardiomyopathy (PDCM) and Aging-related Frailty (AF) programs. These four initial indications address market opportunities of what the Company estimates to be approximately ~$1 billion, ~$5+ billion, ~$1 billion and up to ~$4 billion, respectively. Laromestrocel has delivered several positive initial results across 5 clinical trials in 3 indications: Phase 1 & 2 in AD, Phase 1 & 2 in AF and Phase 1 in HLHS. The Company has completed enrollment for the Phase 2b ELPIS II clinical trial for HLHS, with top-line data anticipated in August 2026.

Longeveron plans to pursue a robust partnering strategy across its development programs to accelerate potential time to market, increase capital use efficiency and leverage the greater resources of larger organizations.

"We are focused on securing strategic licensing partnerships for laromestrocel, founded on both the strength of our clinical data and the growing external validation of our programs," said Stephen H. Willard, Chief Executive Officer of Longeveron. "With stem cell therapy programs in Hypoplastic Left Heart Syndrome, Alzheimer's disease, Pediatric Dilated Cardiomyopathy and Aging-related Frailty, protected by an intellectual property portfolio of 52 global patents spanning composition of matter, methods of use, and manufacturing processes, we believe we have established a durable competitive moat around laromestrocel that provides attractive opportunities for potential partners interested in late stage clinical development programs that address large unmet medical needs."

About laromestrocel (Lomecel-B^®)

Laromestrocel is a living cell product made from specialized cells isolated from the bone marrow of young healthy adult donors. These specialized cells, known as mesenchymal stem cells (MSCs), are essential to our endogenous biological repair mechanism. MSCs have been shown to perform a number of complex functions in the body, including the formation of new tissue. They also have been shown to respond to sites of injury or disease and secrete bioactive factors that are immunomodulatory and regenerative. We believe that laromestrocel MSCs may have multiple potential mechanisms of action that may lead to anti-inflammatory, pro-vascular regenerative responses, and therefore may have broad application for a range of rare and aging related diseases.
