NEW YORK, Aug. 14, 2019 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in cellular medicines for inflammatory diseases, today announced that it intends to provide its allogeneic cell therapy product candidate remestemcel-L for evaluation under an investigator-initiated Investigational New Drug (IND) submission as a potential treatment in children with steroid-refractory chronic graft-versus-host disease (GVHD). The lead investigator will be Dr Joanne Kurtzberg, Jerome Harris Distinguished Professor of Pediatrics and Professor of Pathology, and Director, Pediatric Blood and Marrow Transplant Program at Duke University Medical Center.
In both acute and chronic forms of GVHD, the donated bone marrow stem cells view the recipient's body as foreign, and attack the body causing significant morbidity and mortality. Acute GVHD usually manifests within 100 days following a transplant while chronic GVHD generally manifests later (>100 days), and the two may occur separately or within the same patient.
The incidence of chronic GVHD is increasing and occurs in 30-70% of recipients of both related and unrelated bone marrow transplants.1,2 There are no therapies approved by the United States Food and Drug Administration (FDA) in the 50% of children with chronic GVHD who fail steroids. Mesenchymal stem cells have been used successfully in patients with steroid-refractory chronic GVHD and have been reported to result in durable responses in up to 75% of patients.3-5
Dr Kurtzberg said: "Given my experience with achieving successful outcomes with remestemcel-L in children with steroid-refractory acute GVHD, I look forward to evaluating the treatment's potential as salvage therapy in chronic GVHD, where there remains a significant unmet need."
Earlier this year, Mesoblast initiated filing of a rolling submission for a Biologics License Application (BLA) to the FDA for the use of remestemcel-L in children with steroid-refractory acute GVHD. This BLA submission is based on a successful Phase 3 trial in 55 children with steroid-refractory acute GVHD and supporting results from an Expanded Access Program (EAP) in 241 children. Dr Kurtzberg was the Principal Investigator in both trials.
Mesoblast Limited (Nasdaq: MESO; ASX: MSB) is a world leader in developing allogeneic (off-the-shelf) cellular medicines. The Company has leveraged its proprietary technology platform to establish a broad portfolio of late-stage product candidates with three product candidates in Phase 3 trials - acute graft versus host disease, chronic heart failure and chronic low back pain due to degenerative disc disease. Through a proprietary process, Mesoblast selects rare mesenchymal lineage precursor and stem cells from the bone marrow of healthy adults and creates master cell banks, which can be industrially expanded to produce thousands of doses from each donor without the need for tissue matching. Mesoblast has facilities in Melbourne, New York, Singapore and Texas and is listed on the Australian Securities Exchange (MSB) and on the Nasdaq ( MESO ). www.mesoblast.com
