NEW YORK, July 06, 2020 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB) today announced that an expanded access protocol (EAP) has been initiated in the United States for compassionate use of its allogeneic mesenchymal stem cell (MSC) product candidate remestemcel-L in the treatment of COVID-19 infected children with cardiovascular and other complications of multisystem inflammatory syndrome (MIS-C). Patients aged between two months and 17 years may receive one or two doses of remestemcel-L within five days of referral under the EAP.

The protocol was filed with the United States Food and Drug Administration (FDA) and provides physicians with access to remestemcel-L for an intermediate-size patient population1 under Mesoblasts existing Investigational New Drug (IND) application. According to the FDA, expanded access is a potential pathway for a patient with an immediately life-threatening condition or serious disease or condition to gain access to an investigational medical product for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available.

MIS-C is a life-threatening complication of COVID-19 in otherwise healthy children and adolescents that includes massive simultaneous inflammation of multiple critical organs and their vasculature. In approximately 50% of cases this inflammation is associated with significant cardiovascular complications that directly involve heart muscle and may result in decreased cardiac function. In addition, the virus can result in dilation of coronary arteries with unknown future consequences. Recent articles from Europe and the United States have described this disease in detail.2-5

Mesoblast Chief Medical Officer Dr Fred Grossman said: The extensive body of safety and efficacy data generated to date using remestemcel-L in children with graft versus host disease suggest that our cellular therapy could provide a clinically important therapeutic benefit in MIS-C patients, especially if the heart is involved as a target organ for inflammation. Use of remestemcel-L in children with COVID-19 builds on and extends the potential application of this cell therapy in COVID-19 cytokine storm beyond the most severe adults with acute respiratory distress syndrome.

Remestemcel-L Remestemcel-L is an investigational therapy comprising culture-expanded mesenchymal stem cells derived from the bone marrow of an unrelated donor and is administered in a series of intravenous infusions. Remestemcel-L is believed to have immunomodulatory properties to counteract the inflammatory processes that are implicated in several diseases 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.

Mesoblasts Biologics License Application to seek approval of its product candidate RYONCIL (remestemcel-L) for pediatric steroid-refractory acute graft versus host disease (acute GVHD) has been accepted for priority review by the United States Food and Drug Administration (FDA), and if approved, product launch in the United States is expected in 2020. Remestemcel-L is also being developed for other inflammatory diseases in children and adults including moderate to severe acute respiratory distress syndrome. Mesoblast is completing Phase 3 trials for its product candidates for advanced 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.
