Longeveron Shares Plunge 60% After Pediatric Stem Cell Therapy Misses Primary Goal

Longeveron Inc. (LGVN) shares fell 60% after its stem cell therapy failed to meet the primary goal in a late-stage trial for a rare pediatric heart condition. The company plans to cut costs and explore strategic alternatives. It had $10.1M in cash at the end of June, with operations funded into Q4. The FDA had previously indicated that the trial's primary endpoint alone would not support approval.
