The U.S. FDA has accepted Mesoblast Ltd.’s BLA resubmission for its allogeneic stem cell treatment remestemcel-L in children with steroid-refractory acute graft-vs.-host disease (SR-aGVHD). Mesoblast received a complete response letter from the FDA in October 2020 for remestemcel-L even though approval was highly anticipated after the FDA’s Oncologic Drugs Advisory Committee voted 9-1 that the stem cell therapy showed evidence of efficacy as a treatment for SR-aGVHD in children.
