MESOBLAST MAINTAINS MOMENTUM WITH FDA ON ACCELERATED APPROVAL PATHWAY FOR REVASCOR® IN ISCHEMIC HEART FAILURE AND LABEL EXTENSION FOR RYONCIL® IN ADULTS WITH GVHD Melbourne, Australia; June 12 and New York, USA; June 11, 2025: Mesoblast (ASX:MSB; Nasdaq:MESO), global leader in allogeneic cellular medicines for inflammatory diseases, today provided an update on continued momentum with United States Food and Drug Administration (FDA) regarding both accelerated approval pathway for Revascor® (rexlemestrocel-L) in the treatment of patients with ischemic chronic heart failure with reduced ejection fraction (HFrEF) and inflammation, and label extension for Ryoncil® (remestemcel-L-rknd) in adults with steroid refractory acute graft versus host disease (SR-aGvHD). In the first week of June, Mesoblast held a Type B meeting with FDA under its Regenerative Medicines Advanced Therapy (RMAT) designation for REVASCOR to discuss components of a potential filing for a Biologics License Application (BLA). There was general alignment on items regarding chemistry, manufacturing & controls (CMC), potency assays for commercial product release, and proposed design and primary endpoint for the confirmatory trial post-approval. The Company will await the final minutes from FDA in order to provide detailed feedback and timelines for potential filing. In early July, Mesoblast has an upcoming meeting with FDA to discuss a pivotal trial of Ryoncil® in adults with SR-aGvHD. This trial will be conducted with the NIH-funded Bone Marrow Transplant Clinical Trials Network (BMT-CTN), the objective being to extend the product’s label from children to adults with SR- aGvHD. Ryoncil® is the first and only mesenchymal stromal cell product approved by the FDA for any indication. Ryoncil® became commercially available for purchase in the United States on March 28, 2025, within one quarter of receiving FDA approval to treat children with SR-aGvHD. More than 20 transplant centers will have been onboarded by the end of the quarter, exceeding the company’s expectations at product launch. Mesoblast has continued to expand coverage for Ryoncil® to over 220 million US lives insured by commercial and government payers. To date, 37 of the 51 States provide fee-for-service Medicaid coverage for Ryoncil® through Orphan Drug Lists or medical exception / prior authorization (PA) process. The remainder will come online July 1, 2025, with mandatory coverage for all 24 million lives. “We are very pleased with the momentum of interactions with FDA on both our cardiac and GvHD programs,” said Mesoblast Chief Executive Dr. Silviu Itescu. “We are also encouraged by the strength of the of the Ryoncil® commercial launch, the rate of hospital onboarding, physician adoption, and payor coverage exceeding our expectations in the ten weeks since commercial launch. We will be providing an update on sales of Ryoncil® in our quarterly activities report at the end of next month.” About Mesoblast Mesoblast (the Company) is a world leader in developing allogeneic (off-the-shelf) cellular medicines for the treatment of severe and life-threatening inflammatory conditions. The therapies from the Company’s proprietary mesenchymal lineage cell therapy technology platform respond to severe inflammation by releasing anti-inflammatory factors that counter and modulate multiple effector arms of the immune system, resulting in significant reduction of the damaging inflammatory process. Mesoblast’s RYONCIL® (remestemcel-L) for the treatment of steroid-refractory acute graft versus host disease (SR-aGvHD) in pediatric patients 2 months and older is the first FDA approved mesenchymal stromal cell (MSC) therapy. Please see the full Prescribing Information at www.ryoncil.com. Mesoblast is committed to developing additional cell therapies for distinct indications based on its remestemcel-L and rexlemestrocel-L allogeneic stromal cell technology platforms. RYONCIL is being developed for additional inflammatory diseases including SR-aGvHD in adults and biologic-resistant Exhibit 99.1
inflammatory bowel disease. Rexlemestrocel-L is being developed for heart failure and chronic low back pain. The Company has established commercial partnerships in Japan, Europe and China.
