The company is also looking forward to a meeting with the FDA in early July to discuss a trial of Ryoncil in adults with steroid-refractory acute graft-versus-host disease.

Mesoblast (MESO) said on Thursday it is awaiting the final minutes from the U.S. Food and Drug Administration (FDA) to provide timelines for potential filing for its late-stage product candidate Revascor. Nasdaq-listed shares of the company rose over 3% by Thursday morning.

The biotechnology company is seeking to file an application for the approval of Revascor for the treatment of patients with ischemic chronic heart failure, characterized by an enlarged heart and insufficient blood flow to the organs and extremities of the body. The condition is estimated to affect 2% of the adult population of the United States.

During the meeting held in the first week of June, there was general alignment on items regarding chemistry, manufacturing & controls (CMC), potency assays for commercial product release, and proposed design and primary endpoint for the confirmatory trial post-approval, the company said.

The firm added that it is now awaiting the final minutes from the FDA to determine the timeline for a potential approval filing.

The company is also looking forward to a meeting with the FDA in early July to discuss a trial of Ryoncil in adults with steroid-refractory acute graft versus host disease (SR-aGvHD).
