United States Food & Drug Administration (FDA) Notifies Mesoblast that Available Clinical Data from Phase 3 Trial Appear Sufficient to Support BLA Submission for Remestemcel-L in Children with Steroid-Refractory Acute Graft Versus Host Disease (SR-aGVHD)

NEW YORK, March 25, 2024 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, today announced that U.S. FDA has informed the company that following additional consideration the available clinical data from its Phase 3 study MSB-GVHD001 appears sufficient to support submission of the proposed Biologics License Application (BLA) for remestemcel-L for treatment of pediatric patients with steroid-refractory acute graft versus host disease (SR-aGVHD).

“We thank the agency for their collaborative approach. The responses and guidance from FDA are clear and provide us with a high level of confidence to refile our BLA for remestemcel-L in children with SR-aGVHD,” said Mesoblast CEO Dr. Silviu Itescu.

Mesoblast intends to file the resubmission during the next quarter, seeking to address all remaining product characterization issues.

About Mesoblast
Mesoblast (the Company) is a world leader in developing allogeneic (off-the-shelf) cellular medicines for the treatment of severe and life-threatening inflammatory conditions. The Company has leveraged its proprietary mesenchymal lineage cell therapy technology platform to establish a broad portfolio of late-stage product candidates which respond to severe inflammation by releasing anti-inflammatory factors that counter and modulate multiple effector arms of the immune system, resulting in significant reduction of the damaging inflammatory process.

Mesoblast has a strong and extensive global intellectual property portfolio with protection extending through to at least 2041 in all major markets. The Company’s proprietary manufacturing processes yield industrial-scale, cryopreserved, off-the-shelf, cellular medicines. These cell therapies, with defined pharmaceutical release criteria, are planned to be readily available to patients worldwide.

Mesoblast is developing product candidates for distinct indications based on its remestemcel-L and rexlemestrocel-L allogeneic stromal cell technology platforms. Remestemcel-L is being developed for inflammatory diseases in children and adults including steroid refractory acute graft versus host disease, and biologic-resistant inflammatory bowel disease. Rexlemestrocel-L is being developed for advanced chronic heart failure and chronic low back pain. Two products have been commercialized in Japan and Europe by Mesoblast’s licensees, and the Company has established commercial partnerships in Europe and China for certain Phase 3 assets.
