Mesoblast Partners with BMT CTN for Pivotal Trial of Ryoncil
Mesoblast Limited (NASDAQ: MESO; ASX: MSB) has made a significant announcement about the upcoming pivotal trial of Ryoncil (remestemcel-L-rknd), focusing on treating adults suffering from severe acute graft versus host disease (aGvHD) that does not respond to corticosteroids. The company's collaboration with the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) seeks to address this critical health issue arising in patients who experience high mortality rates associated with aGvHD.
The Challenges Faced by Patients with Severe aGvHD
Adults afflicted with severe acute graft versus host disease often do not respond well to existing treatments. In particular, studies have shown that 44-58% of adults treated with ruxolitinib did not achieve a response within the first 28 days. This lack of effective response poses a grave concern as survival rates for those who fail ruxolitinib can plummet to as low as 20-30% by day 100. Thankfully, Ryoncil has shown promising results, with 76% survival rates at the same interval within Mesoblast's Expanded Access program.
Aiming for Better Outcomes
To improve patient outcomes, Mesoblast has engaged with the FDA to determine the optimal patient population and timing for this new trial of Ryoncil in adults with severe steroid-refractory aGvHD. The approach will involve randomizing participants shortly after they become corticosteroid-refractory, enabling them to either receive ruxolitinib alone or in combination with Ryoncil. This strategy is designed to provide these patients with the best chance for improved survival.
Expert Insights on Collaboration
Dr. John Levine, who chairs the BMT CTN Steering Committee, expressed excitement about this partnership, recognizing the potential of Ryoncil as a life-saving option. The FDA has previously approved Ryoncil for use in children and adolescents, and this trial seeks to extend its availability to adults facing this severe condition.
