Longeveron Announces Publication of Final Data from ELPIS I Trial of Lomecel-BTM for Hypoplastic Left Heart Syndrome in Peer-Reviewed Journal


-- Full results published in European Heart Journal Open --

-- Study met primary safety endpoint --

-- All patients alive, transplant-free, and maintained expected rate of growth one year after treatment --

-- Data supports ongoing clinical development of Lomecel-BTM for HLHS, currently being evaluated in a Phase 2a trial --

MIAMI, Jan. 19, 2023 (GLOBE NEWSWIRE) --  Longeveron Inc. (NASDAQ: LGVN) ("Longeveron" or "Company"), a clinical stage biotechnology company developing regenerative medicines for unmet medical needs, today announced the publication of the full results from the Company’s ELPIS I trial of Lomecel-BTM for hypoplastic left heart syndrome (HLHS) in the European Heart Journal Open. In the uncontrolled open-label Phase 1b study entitled “Intramyocardial cell-based therapy with Lomecel-B during bidirectional cavopulmonary anastomosis for hypoplastic left heart syndrome: The ELPIS phase I trial,” patients (n=10) underwent the Glenn Procedure (an open heart surgery) at approximately 4-5 months old, and received intracardiac injections of Lomecel-BTM.

“We are pleased that the data from the ELPIS I trial have been published in European Heart Journal Open,” said Chris Min, M.D., Ph.D., Interim Chief Executive Officer and Chief Medical Officer. “This data supports our conviction that Lomecel-BTM has the potential to alter the treatment landscape for patients with HLHS, a rare and life-threatening congenital heart disease. Notably, the procedure appeared to be generally safe and well-tolerated in the babies undergoing heart surgery in the first 6 months of life. The study provisionally shows suggestions of possible improvement in measures of cardiac function, findings that are presently being tested in our ongoing controlled and randomized Phase 2 study.”

The ELPIS I study was conducted by a consortium of leading pediatric cardiac surgeons led by Sunjay Kaushal, M.D., Ph.D., currently Division Head of Cardiovascular-Thoracic Surgery at Lurie Children’s and principal investigator of the ELPIS I study. Dr. Kaushal said, “On behalf of the families affected with this devastating condition and my surgical colleagues, we are thrilled to publish these results. We are hopeful we may be able to add this therapy to the armamentarium for managing babies with HLHS.”

The findings of the study included:

  1. None of the children experienced the prespecified safety endpoint over one year of follow-up. The procedure was generally well-tolerated in all ten study participants.
  2. The babies maintained their weight-for-age z-score after the surgery, and all were alive and transplant-free one year following the procedure.
  3. Several indices of right ventricular (RV) function, notably the tricuspid regurgitation fraction, showed suggestions of either improvement or prevention of deterioration over one-year following the surgery.
  4. In a sub-study of 6 babies, a blood test showed evidence of the persistence and activity of Lomecel-BTM one week after injection.

Longeveron is currently enrolling patients in the ELIS II trial, a 38-patient, randomized (1:1), blinded, controlled Phase 2a clinical trial intended to evaluate the safety and efficacy of intramyocardial injection of Lomecel-BTM in infants with HLHS who are undergoing the Glenn Procedure. This ongoing trial is funded by a grant from the National Heart, Lung, and Blood Institute. Lomecel-BTM for HLHS has received Fast Track, Rare Pediatric Disease, and Orphan Drug Designations from the U.S. Food and Drug Administration (FDA).

About Hypoplastic Left Heart Syndrome
Hypoplastic left heart syndrome (HLHS) is a rare and life-threatening congenital heart defect affecting approximately 1,000 babies per year. Infants born with HLHS have an underdeveloped or absent left ventricle. Current standard-of-care is comprised of three reconstructive heart surgeries to reposition the right ventricle to cardiac function. These three surgeries must be performed within the first five years of life. The first surgery (the Norwood procedure) is conducted within 2 weeks of birth and the second (the Glenn procedure) is conducted by 4-5 months of age. A final third operation is performed when the children are 4-5 years of age. Without surgical treatment, the condition is always fatal, and even with reconstructive surgical reconstruction, patients often die or require heart transplantation by age 15.
