FDA ACCEPTS MESOBLAST’S BIOLOGICS LICENCE APPLICATION FOR RYONCIL™ AND AGREES TO PRIORITY REVIEW

2020-04-01 06:00 ET - News Release

NEW YORK, April 01, 2020 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq: MESO; ASX:MSB), global leader in cellular medicines for inflammatory diseases, today announced that the United States Food and Drug Administration (FDA) has accepted for priority review the Company’s Biologics License Application (BLA) filing for RYONCILTM (remestemcel-L), its allogeneic cell therapy for the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD). The FDA has set a Prescription Drug User Fee Act (PDUFA) action date of September 30, 2020, and if approved, Mesoblast will make RYONCIL immediately available in the United States.

A Priority Review designation will direct overall attention and resources to the evaluation of applications for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. The FDA has advised that they are planning to hold an Advisory Committee Meeting to discuss this application.

Mesoblast Chief Executive Dr Silviu Itescu stated: “There is a critical need to improve survival outcomes in children suffering from the more advanced stages of this devastating disease. The acceptance of the BLA represents an important milestone for the Company. Mesoblast is on track in its preparation for the potential launch of RYONCIL, including meeting its target inventory build and commercial team roll-out.”

About Acute GVHD
Acute GVHD occurs in approximately 50% of patients who receive an allogeneic bone marrow transplant (BMT). Over 30,000 patients worldwide undergo an allogeneic BMT annually, primarily during treatment for blood cancers, and these numbers are increasing.1 In patients with the most severe form of acute GVHD (Grade C/D or III/IV) mortality is as high as 90% despite optimal institutional standard of care.2,3. There are currently no FDA-approved treatments in the US for children under 12 with SR-aGVHD.

About RYONCILTM
Mesoblast’s lead product candidate, RYONCIL (remestemcel-L), is an investigational therapy comprising culture- expanded mesenchymal stem cells derived from the bone marrow of an unrelated donor. It is administered to patients in a series of intravenous infusions. RYONCIL is believed to have immunomodulatory properties to counteract the inflammatory processes that are implicated in SR- aGVHD by down-regulating the production of pro-inflammatory cytokines, increasing production of anti-inflammatory cytokines, and enabling recruitment of naturally occurring anti-inflammatory cells to involved tissues.

Mesoblast Limited (Nasdaq: MESO; ASX:MSB) is a world leader in developing allogeneic (off-the-shelf) cellular medicines. The Company has leveraged its proprietary mesenchymal lineage cell therapy technology platform to establish a broad portfolio of commercial products and late-stage product candidates. Mesoblast’s proprietary manufacturing processes yield industrial-scale, cryopreserved, off-the-shelf, cellular medicines.

Mesoblast has filed a Biologics License Application to the United States Food and Drug Administration (FDA) to seek approval of its product candidate RYONCIL™ (remestemcel-L) for steroid-refractory acute graft versus host disease (acute GvHD). Remestemcel-L is also being developed for other rare diseases. Mesoblast is completing Phase 3 trials for its product candidates for advanced heart failure and chronic low back pain. If approved, RYONCIL is expected to be launched in the United States in 2020 for pediatric steroid-refractory acute GVHD.
