Oral presentation highlights findings that patients treated with Lomecel-BTM in ELPIS I, in an open-label follow-on study, experienced 5-year survival after stage 2 Glenn surgery of 100% with none requiring heart transplant; this compared to the largest data set from the Single Ventricle Reconstruction Trial which showed 83% survival, with a 5.2% heart transplantation rateELPIS I met its primary endpoint of safety through 1-year post-treatment, with 100% survival rate, 100% transplant-free and patients maintained expected rate of growth one year after treatmentFindings support cell based therapy as a potential adjunct to HLHS reconstruction surgery to improve clinical benefits and reduce the need for subsequent heart transplantationELPIS II Phase 2b clinical trial is currently ongoing, further evaluating Lomecel-BTM as a potential adjunct therapy for HLHS versus standard of care alone MIAMI, Oct. 27, 2024 (GLOBE NEWSWIRE) — Longeveron Inc. (NASDAQ: LGVN), a clinical stage biotechnology company developing regenerative medicines, today announced that its positive long-term transplant-free survival data from a multi-year follow-on study to the ELPIS I Phase 1 clinical trial were featured in an oral presentation at the Congenital Heart Surgeons’ Society (CHSS) 51st Annual Meeting taking place October 27-28, 2024 in Chicago, Illinois. “HLHS is a devastating disease for patients and their families, so I am impressed and very encouraged to see the continued long-term survival of patients treated with Lomecel-BTM in the ELPIS I study,” said Sunjay Kaushal, M.D., Ph.D., Professor of Surgery, Cardiovascular and Thoracic Surgery at University of Nevada, Las Vegas. “Even with current comprehensive treatment, only 50% to 60% of infants survive to adolescence due to right ventricular failure and for those that are surviving, parents are strongly seeking to avoid transplant. There is clearly an important unmet medical need to improve right ventricular function in these infants to positively impact both short- and long-term patient outcomes, and stem cell therapy, particularly Lomecel-BTM, has the potential to play a critical role in treating these patients.” ELPIS I was an open-label, Phase 1 clinical trial designed to evaluate the safety of Lomecel-BTM in patients with HLHS. Patients underwent the Glenn Procedure (an open-heart surgery) at approximately 4-5 months of age. The results from the ELPIS I trial, which were previously reported, and published in the European Heart Journal Open in 2023, showed that the study met its primary safety endpoint and that all patients were alive, transplant-free, and maintained their expected rate of growth one year after treatment. To assess long-term survival benefits, all ELPIS I patients (n=10, 7 males, and 3 females) were followed for five years post-Glenn surgery and treatment with Lomecel-BTM to evaluate overall survival and transplant-free survival. Outcomes were compared with long-term historical data from patients in the Single Ventricle Reconstruction (SVR) Trial receiving the same shunt type at Stage I (Norwood) operation and underwent Glenn procedures. Key findings include: 5-year post-Glenn procedure Kaplan-Meier survival was 100% in patients treated with Lomecel-B™ in ELPIS I, with none requiring heart transplant. This compared to 83% (95% CI= [77.4, 89.3]) transplant-free survival in the SVR trial through 5 years post-Glenn surgery, and a 5.2% (95% CI= [2.0, 8.3]) heart transplantation rate.No Major Adverse Cardiovascular Events (MACE) were reported during the study.No Lomecel-BTM related safety issues were reported.These findings support the use of Lomecel-BTM as a potential adjunct to HLHS reconstruction surgery to improve transplant-free survival. ELPIS II is a Phase 2b randomized clinical trial further evaluating Lomecel-BTM, compared to standard of care, as a potential adjunct therapy for HLHS. ELPIS II is on-going and enrolling 38 pediatric patients at twelve premiere infant and children’s treatment institutions across the country. The clinical trial 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. The U.S. Food and Drug Administration (FDA) has granted Lomecel-B™ Orphan Drug designation, Fast Track designation, and Rare Pediatric Disease designation, which allow greater access to the FDA during Lomecel-BTM’s development for HLHS. “We believe these results provide further validation of both the safety and therapeutic potential of Lomecel-B™ in the treatment of HLHS and suggest, with further clinical evaluation, that this cellular therapy has the potential to have a positive impact on patients afflicted with this devastating disease,” said Joshua Hare, M.D., Co-founder, Chief Science Officer, and Chairman at Longeveron. “Based on the strength of the ELPIS I data, we are currently conducting the ELPIS II Phase 2b clinical trial evaluating our cellular therapy Lomecel-BTM as an adjunct therapy for treating HLHS, which, if positive, may serve as the foundation for a BLA submission for potential approval of Lomecel-BTM.” About Hypoplastic Left Heart Syndrome (HLHS)HLHS is a rare congenital heart defect that effects approximately 1,000 infants per year in the U.S. Infants with HLHS are born with an underdeveloped left ventricle, which creates a life-threatening condition due to the heart’s inability to pump adequate amounts of blood throughout the body. The current treatment requires infants to undergo a complex three-stage heart reconstruction surgery process over the first five years of their life. Even with this comprehensive treatment, only 50% to 60% of infants survive to adolescence due to right ventricular failure. There is clearly an important unmet medical need to improve right ventricular function in these infants to positively impact both short- and long-term patient outcomes. About Lomecel-B™Lomecel-B™ is a living cell product made from specialized cells isolated from the bone marrow of young healthy adult donors. These specialized cells, known as medicinal signaling 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 Lomecel-B™ 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. About Longeveron Inc.Longeveron is a clinical stage biotechnology company developing regenerative medicines to address unmet medical needs. The Company’s lead investigational product is Lomecel-B™, an allogeneic medicinal signaling cell (MSC) therapy product isolated from the bone marrow of young, healthy adult donors. Lomecel-B™ has multiple potential mechanisms of action encompassing pro-vascular, pro-regenerative, anti-inflammatory, and tissue repair and healing effects with broad potential applications across a spectrum of disease areas. Longeveron is currently pursuing three pipeline indications: hypoplastic left heart syndrome (HLHS), Alzheimer’s disease (AD), and Aging-related Frailty. Lomecel-BTM development programs have received five distinct and important U.S. FDA designations: for the HLHS program – Orphan Drug designation, Fast Track designation, and Rare Pediatric Disease designation; and, for the AD program – Regenerative Medicine Advanced Therapy (RMAT) designation and Fast Track designation.
