Mesoblast Limited has announced an update on the commercial experience with Ryoncil® (remestemcel-L-rknd), the first mesenchymal stromal cell $(MSC)$ product approved by the U.S. Food & Drug Administration (FDA) for any indication. Since its commercial availability in March 2025 for children aged 2 months and older with steroid-refractory acute graft-versus-host disease (SR-aGvHD), real-world data from the first 25 patients treated showed an 84% survival rate after completing the initial 28-day treatment regimen. Mesoblast is also preparing to expand the FDA label for Ryoncil® to adults with severe SR-aGvHD, with a pivotal trial in adults to be conducted with the NIH-funded Bone Marrow Transplant Clinical Trials Network (BMT-CTN) expected to commence site enrollment this quarter. The company has established the MyMesoblast™ patient access hub and coverage for Ryoncil® now extends to more than 260 million U.S. lives through government and commercial payers. Results from the adult pivotal trial are yet to be presented.
