NEW YORK, Oct. 02, 2022 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, announced today that it has submitted to the U.S. Food and Drug Administration (FDA) substantial new information on clinical and potency assay items identified in the Complete Response Letter (CRL) received from FDA in September 2020 to the Biologics License Application (BLA) for remestemcel-L in the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD).

Mesoblast has maintained an active dialog with the FDA since receiving the CRL, and the substantial new information submitted to the Investigational New Drug (IND) file for remestemcel-L in the treatment of children with SR-aGVHD, as guided by FDA, represents a major milestone in the Companys complete response to the FDA. Remestemcel-L has been granted Fast Track Designation and BLA Priority Review from the FDA.

Survival outcomes have not improved over the past two decades for children or adults with the most severe forms of SR-aGVHD.1-3 The lack of any approved treatments for children under 12 means that there is an urgent need for a therapy that improves the dismal survival outcomes in children.

The submission summarizes controlled data providing further evidence of remestemcel-Ls ability to save lives, said Dr. Silviu Itescu, Chief Executive of Mesoblast. Additionally, the improved process controls we have put in place to assure robust and consistent commercial product, together with a potency assay that predicts consistent survival outcomes, makes remestemcel-L a compelling treatment for these children.

About Steroid-refractory Acute Graft Versus Host Disease 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, including about 20% in pediatric patients.4,5 SR-aGVHD is associated with mortality as high as 90% and significant extended hospital stay costs.6,7 There are currently no FDA-approved treatments in the US for children under 12 with SR-aGVHD.

About Mesoblast Mesoblast 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 Companys 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, biologic-resistant inflammatory bowel disease, and acute respiratory distress syndrome. Rexlemestrocel-L is in development for advanced chronic heart failure and chronic low back pain. Two products have been commercialized in Japan and Europe by Mesoblasts licensees, and the Company has established commercial partnerships in Europe and China for certain Phase 3 assets.

Mesoblast has locations in Australia, the United States and Singapore and is listed on the Australian Securities Exchange (MSB) and on the Nasdaq (MESO). For more information, please see http://www.mesoblast.com, LinkedIn: Mesoblast Limited and Twitter: @Mesoblast
