Mesoblast Limited (ASX:MSB; Nasdaq:MESO), world leader in development and commercialization of allogeneic (off-the-shelf) cellular medicines, today announced that it has completed patient recruitment in the events-driven Phase 3 trial of its product candidate Revascor (MPC-150-IM) for advanced chronic heart failure.
Mesoblast Chief Executive Dr Silviu Itescu stated: “Completion of recruitment in this Phase 3 trial, the largest cell therapy trial for heart failure, is a key milestone for Mesoblast and has been achieved on plan. This is a substantial step forward in our objective to bring an effective therapy to countless patients with progressive heart failure, and a tremendous commercial opportunity for Mesoblast.”
The Phase 3 trial is evaluating whether Revascor reduces recurrent non-fatal heart failure-related major adverse cardiac events (HF-MACE), and prevents or delays terminal cardiac events (TCEs), defined as cardiovascular death, heart transplant or placement of an artificial device, over at least 12 months. In a previous Phase 2 trial, a single dose of Revascor prevented any TCEs or hospitalization events over three years in a similar patient cohort.
The Phase 3 trial has enrolled approximately 570 patients across 55 centers in North America. This enrollment target was guided by the observed reduction in event rate in the Phase 2 trial and reinforced by the successful outcome of a pre-specified futility analysis of the Phase 3 trial’s primary endpoint performed after the first 270 patients were enrolled.
The trial’s co-principal investigator, Dr Emerson Perin, Medical Director of Texas Heart Institute and Director of its Stem Cell Center, said: “We are very pleased to have completed recruitment in this important trial of a cellular therapy for advanced heart failure patients who have few alternatives. If the Phase 3 trial results confirm the earlier Phase 2 data, where we saw improvements in patient function as well as reductions in hospitalizations and deaths, this important technology will transform cardiovascular care and would provide a powerful new treatment for advanced heart failure.”
There are over 8 million patients with heart failure in the United States alone, with 15-20% refractory to all existing medicines and progressing to advanced heart failure1(New York Heart Association Class III or IV). These patients represent a major unmet medical need due to their high rates of HF-MACE events and mortality.
Dr Itescu added: “Over the past 12 months, Mesoblast has completed recruitment in all three of its Phase 3 trials, for acute graft versus host disease, chronic low back pain, and now chronic heart failure.”
