Longeveron® Completes Enrollment for HLHS Treatment Study

Longeveron® Completes Enrollment for HLHS Treatment Study

In an exciting development for pediatric heart health, Longeveron Inc. (NASDAQ: LGVN), a clinical-stage regenerative medicine biotechnology company, proudly announces the completion of enrollment for its pivotal Phase 2b clinical trial, known as ELPIS II. This study evaluates laromestrocel, an investigational cellular therapy aimed at treating Hypoplastic Left Heart Syndrome (HLHS), a rare but serious congenital heart disease.

Significance of ELPIS II Trial

The ELPIS II trial has gathered a cohort of 40 young participants with HLHS from twelve renowned pediatric institutions. The primary goal is to assess the treatment's effectiveness based on survival rates at 12 months, along with metrics like hospitalization duration and improvements in cardiac function.

Impact on Pediatric Patients

“Completing enrollment in this crucial trial marks a significant milestone towards providing a new treatment avenue for infants suffering from HLHS,” commented Dr. Nataliya Agafonova, the Chief Medical Officer of Longeveron. HLHS treatment today involves a complex series of surgeries that can be life-saving but still leaves many children vulnerable. With the current survival rate of only about 50% reaching adolescence, the need for innovative therapies such as laromestrocel has never been more urgent.

Promising Results from Previous Trials

The impetus for continuing research into laromestrocel stems from its promising outcomes in earlier studies. ELPIS I, the predecessor to this ongoing trial, reported a remarkable 100% transplant-free survival rate up to five years post-Glenn surgery in children treated with laromestrocel. This exponential success rate stands in stark contrast to historical data showcasing a mortality rate of approximately 20% in similar demographics.

Regulatory Designations and Support

In recognition of its potential, the U.S. FDA has granted laromestrocel several designations, including Orphan Drug designation and Rare Pediatric Disease designation. These acknowledgments highlight the critical need for effective treatment options for HLHS and simplify the pathway for bringing necessary therapies to market. Furthermore, a successful transition into full market approval could unlock significant financial resources, potentially valued near $1 billion in the U.S.

What Lies Ahead for Longeveron

As we look forward, Longeveron is eager to share the top-line results from the ELPIS II trial, expected in the third quarter of 2026. Should results prove positive, the company will pursue a Biological License Application (BLA) for laromestrocel, potentially transforming the landscape of treatment options for HLHS and validating the dedicated efforts of families, clinicians, and researchers involved in this journey.

Community and Collaboration

Collaboration has been pivotal in this endeavor. The ongoing ELPIS II trial is conducted in partnership with the National Heart, Lung, and Blood Institute (NHLBI) and is supported through grants from the National Institutes of Health (NIH). Such partnerships underscore the nationwide commitment to combatting pediatric heart diseases effectively.

About Hypoplastic Left Heart Syndrome

Hypoplastic Left Heart Syndrome is characterized by the underdevelopment of the left side of the heart, which can severely hinder blood flow throughout the body. Those born with HLHS typically require extensive surgical interventions early in life, presenting various challenges that necessitate innovative treatment strategies. The urgency to improve outcomes for these infants remains a top priority among healthcare providers and researchers.
