KEY OUTCOMES FROM FDA TYPE A MEETING AND MESOBLAST NEXT STEPS TO ACHIEVE RYONCIL APPROVAL Melbourne, Australia; September 21 and New York, USA; September 20, 2023: Mesoblast Limited (ASX:MSB; Nasdaq:MESO), global leader in allogeneic cellular medicines for inflammatory diseases, today provided an update on the path to approval for its lead-product candidate remestemcel- L in the treatment of pediatric and adult steroid-refractory acute graft versus host disease (SR-aGvHD), following a Type A meeting held with the United States Food and Drug Administration (FDA). FDA clarified that the key remaining issue for pediatric approval is providing further evidence that the potency assay will assure the consistent efficacy of commercial product. The key outcomes of the meeting and Mesoblast next steps are: • Mesoblast summarised the large body of existing clinical data with the improved Ryoncil® product version of remestemcel-L, manufactured after 2008 using the current process inspected by FDA, for potential approval in children. • Mesoblast presented clinical data indicating that RYONCIL was associated with much higher survival of children with SR-aGVHD in the Expanded Access Protocol (EAP) compared with the earlier Prochymal version manufactured before 2008. • Mesoblast presented consistently high survival in patients treated in RYONCIL, in children with SR-aGVHD in the EAP between 2008-2015, in the Phase 3 trial MSB-GVHD001 between 2015- 2018, and in the Emergency Investigational New Drug (EIND) protocol from 2015-2023. • FDA noted that the lack of a suitable potency assay for the RYONCIL product used during the Phase 3 trial MSB-GVHD001 for the pediatric acute GVHD indication has prevented the trial from being considered an adequate study for the purpose of demonstrating substantial evidence of effectiveness required for a marketing approval. • Mesoblast intends to generate in the coming months new potency assay data for RYONCIL showing that the product used during pediatric Phase 3 trial MSB-GVHD001 was standardized as to its identity, strength, quality, purity, and dosage form to give significance to the results of the investigation as described in the Code of Federal Regulations for adequate and well- controlled studies (21 CFR 314.126), and that commercial batches made for the pediatric indication will meet the same standard. • Mesoblast believes these additional data will provide a link between the RYONCIL product that was used in the Phase 3 trial MSB-GVHD001 for the pediatric indication to the RYONCIL product which will be used in a future trial for the adult indication. • To address the adult indication, Mesoblast proposed an externally controlled single-arm registration trial design in adults and children over age 12 with SR-aGVHD who have failed both steroids and a second line agent, such as ruxolitinib, to be underpinned by a suitable potency assay. • Mesoblast intends to perform this trial in partnership with world-leading investigators at the Blood and Marrow Clinical Trials Network (BM CTN), a body responsible for approximately 80% of all US transplants, with the costs expected to be covered by previously announced reductions in operational spend. • FDA indicated its willingness to consider Mesoblast’s proposed registrational trial design in adults, subject to agreement on the suitability of the potency assay for the product to be used in adults. Mesoblast expects to receive the formal minutes of the Type A meeting within three weeks. Mesoblast Chief Executive Silviu Itescu said: “We had a very productive meeting with the FDA’s review team, allowing us to establish the path forward for potential approval of remestemcel-L in SR-aGVHD. We are gathering the additional potency assay data required to demonstrate the ability of Mesoblast’s potency assay to show both the product used in the Phase 3 trial in children and the product made for
commercial release are standardized. In parallel, we are focused on initiating a registration trial in adults in partnership with world-leading investigators at the Blood and Marrow Clinical Trials Network.” 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 Company has leveraged its proprietary mesenchymal lineage cell therapy technology platform to establish a broad portfolio of late- stage product candidates which 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 has a strong and extensive global intellectual property portfolio with protection extending through to at least 2041 in all major markets. The Company’s proprietary manufacturing processes yield industrial-scale, cryopreserved, off-the-shelf, cellular medicines. These cell therapies, with defined pharmaceutical release criteria, are planned to be readily available to patients worldwide. Mesoblast is developing product candidates for distinct indications based on its remestemcel-L and rexlemestrocel-L allogeneic stromal cell technology platforms. Remestemcel-L is being developed for inflammatory diseases in children and adults including steroid refractory acute graft versus host disease, biologic-resistant inflammatory bowel disease, and acute respiratory distress syndrome. Rexlemestrocel-L is in development for advanced chronic heart failure and chronic low back pain. Two products have been commercialized in Japan and Europe by Mesoblast’s licensees, and the Company has established commercial partnerships in Europe and China for certain Phase 3 assets. Mesoblast has locations in Australia, the United States and Singapore and is listed on the Australian Securities Exchange (MSB) and on the Nasdaq (MESO).
