$LGVNPress releaseOct 26, 2026, 9:15 AM ETRead the release

Longeveron announced updated Phase 2b ELPIS II results for laromestrocel in hypoplastic left heart syndrome: the trial missed its primary endpoint of right ventricular ejection fraction improvement at 12 months (p=0.68). However, the pre-specified secondary endpoint of major adverse cardiac events achieved statistical significance, with 8 events in the standard-of-care arm versus 1 in the laromestrocel arm (P=0.043), and no treatment-related serious adverse events were identified.
