Mesoblast (ASX:MSB), a global leader in allogeneic cellular medicines, has received U.S. FDA approval to accelerate rexlemestrocel-L (Revascor) for patients with end-stage ischemic heart failure and reduced ejection fraction (HFrEF) with a left ventricular assist device (LVAD).

The feedback follows a Type B meeting on February 21, 2024, under the Regenerative Medicine Advanced Therapy (RMAT) designation.

“We are very pleased with FDA’s feedback that the presented results from our pivotal study of rexlemestrocel-L in end-stage HFrEF patients with LVADs may support an accelerated approval,” Mesoblast CEO Dr Silviu Itescu said.
