PORTFOLIO UPDATE Ryoncil® (remestemcel-L) U.S. Launch for Steroid-Refractory Acute Graft Versus Host Disease On December 18, 2024, Ryoncil® (remestemcel-L) became the first mesenchymal stromal cell (MSC) therapy approved by U.S. FDA for any indication.FDA approved Ryoncil® as the first and only therapy for pediatric patients 2 months and older, including adolescents and teenagers, with steroid-refractory acute graft versus host disease (SR-aGvHD), a life-threatening condition with high mortality rates.Ryoncil® planned for launch this quarter once Company receives National Drug Codes (NDC) from FDA, enabling subsequent publication of product pricing in the U.S. Price Compendia.The U.S. launch of Ryoncil® will be led by Mesoblast’s commercial leadership team comprising Marcelo Santoro, Chief Commercial Officer, a seasoned pharmaceutical executive with over three decades of experience successfully leading high-performing teams at Pfizer, Otsuka, and AstraZeneca, with a proven track record of launching innovative therapies, including the creation of multi-billion-dollar brands and the execution of global product launches.Peter McSweeney, MB ChB FRACP, Head of Medical Affairs, is a hematologist and bone-marrow transplant specialist with over 30 years’ experience. He has worked at the Fred Hutchinson Cancer Research Center, has been Clinical Director at the University of Colorado’s Blood & Marrow Transplant Program, and more recently Director of Cellular Therapy at Colorado Blood Cancer Institute. He has extensive experience in the clinical application and research of allogeneic and autologous transplantation, CAR-T cell therapy, and has many publications in these areas.Commercial and medical affairs functions will be supported by a team of key account managers (KAMs) and medical science liaisons (MSLs), respectively, to provide critical infrastructure for the commercial function and engagement and servicing of treatment centers. Commercial launch strategy will initially target those centers with greatest experience using the Ryoncil® product and highest volume, followed by a broader staged rollout. Half of all pediatric transplants are performed at just 15 centers across the U.S. Our commercial team will be heavily engaged in these centers of excellence along with another 30 sites, which together account for almost 80% of pediatric transplants.Commercial inventory has been manufactured and a distribution network has been established using Cencora, a leader in specialty pharmaceutical services and distribution. Cencora will leverage its cryogenic logistics capabilities and state-of-the art cryogenic storage infrastructure, to enable the efficient and secure delivery of cryopreserved product to U.S. treatment centers.Our patient access hub, MyMesoblast™, has been established and will be managed by Cencora to facilitate patient enrollment, shipment & logistics, and will provide support for patients in the inpatient and outpatient setting.Mesoblast will have a significant presence, including scientific presentations and exhibitor booth, at the industry’s most important meeting, the 2025 Transplantation & Cellular Therapy Meetings (Tandem Meetings) of the American Society for Transplantation and Cellular Therapy (ASTCT) and the Center for Blood and Marrow Transplant Research (CIBMTR), taking place February 12-15 in Honolulu, HI. Ryoncil® Label Extension in Pediatric & Adult Inflammatory Diseases Mesoblast is developing a comprehensive clinical, regulatory and commercial strategy to build a pediatric inflammatory disease franchise using Ryoncil® to target diseases of high unmet need given the extensive safety profile of the product in children, the unique mechanism of action of Ryoncil®, and the limited options available for these inflammatory conditions.For adult patients, Mesoblast is collaborating with Blood and Marrow Transplant Clinical Trials Network (BMT CTN) in the United States, a body that is funded by the National Institutes of Health (NIH) and is responsible for approximately 80% of all US allogeneic BMTs, to conduct a pivotal trial in adults with SR-aGVHD.Survival in adults with SR-aGVHD who have failed at least one additional agent, such as ruxolitinib, remains as low as 20-30% by 100 days.1,2 In contrast, 100-day survival was 73% after Ryoncil® treatment was used under expanded access in 25 adults with SR-aGVHD who failed to respond to at least one additional agent, such as ruxolitinib. Revascor® (rexlemestrocel-L) for Chronic Heart Failure with Reduced Ejection Fraction (HFrEF) and Persistent Inflammation In 2024 FDA informed Mesoblast that it supports an accelerated approval pathway for REVASCOR, Mesoblast’s second generation allogeneic, STRO3-immunoselected, and industrially manufactured stromal cell therapy, in patients with end-stage ischemic HFrEF kept alive with a left ventricular assist device (LVAD).Accelerated approval to market REVASCOR, if received, will require Mesoblast to commit to a post-approval confirmatory study in NYHA Class II/III HFrEF patients which could result in full approval in the broader HFrEF population.In November 2024 a publication in the prestigious peer-reviewed European Journal of Heart Failure (EJHF) reported that a single intramyocardial injection of REVASCOR results in improved survival in high-risk NYHA Class II/III patients with ischemic heart failure and inflammation.3 This identifies the HFrEF population that is responsive to REVASCOR and will be the target of a confirmatory trial after accelerated approval, if received.Under its Regenerative Medicine Advanced Therapy (RMAT) designation Mesoblast intends to meet with FDA to discuss data presentation, timing and FDA expectations for an accelerated approval filing in these patients. Revascor® for Pediatric Congenital Heart Disease - Hypoplastic Left Heart Syndrome U.S. FDA granted REVASCOR a RMAT designation following submission of results from the randomized controlled trial in children with hypoplastic left heart syndrome (HLHS), a potentially life-threatening congenital heart condition.Earlier in 2024, FDA granted REVASCOR both Rare Pediatric Disease Designation (RPDD) and Orphan-Drug Designation (ODD) for treatment of children with HLHS.RMAT designations aim to expedite the development of regenerative medicine therapies intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition where preliminary clinical evidence indicates that the therapy has the potential to address unmet medical needs for the disease or condition. An RMAT designation for rexlemestrocel-L provides all the benefits of Breakthrough and Fast Track designations, including rolling review and eligibility for priority review on filing of a Biologics License Application (BLA).On FDA approval of a BLA for REVASCOR for the treatment of HLHS, if received, Mesoblast may be eligible to receive a Priority Review Voucher (PRV) that can be redeemed for any subsequent marketing application or may be sold or transferred to a third party. Rexlemestrocel-L for Chronic Low Back Pain associated with Degenerative Disc Disease – Phase 3 Program The confirmatory Phase 3 trial of Mesoblast’s second generation allogeneic, STRO3-immunoselected, and industrially manufactured stromal cell product candidate rexlemestrocel-L in patients with chronic low back pain (CLBP) due to inflammatory degenerative disc disease (DDD) of less than five years duration has commenced enrollment and treatment at multiple sites across the U.S.The capital raise concluded this month will facilitate expansion of sites enrolling in the trial and acceleration of patient accrual. FDA has previously agreed on the design of this 300-patient randomized, placebo-controlled confirmatory Phase 3 trial, and the 12-month primary endpoint of pain reduction as an approvable indication.This endpoint was successfully met in Mesoblast’s first Phase 3 trial. Key secondary measures include improvement in quality of life and function.A particular focus is on treatment of patients on opioids, since discogenic back pain accounts for approximately 50% of prescription opioid usage in the US. Significant pain reduction and opioid cessation were observed in Mesoblast’s first Phase 3 trial.FDA has designated rexlemestrocel-L a RMAT for the treatment of chronic low back pain.
