6 m e s o b l a s t During the six-month BLA review we made substantial progress towards bringing this cutting-edge product to market with completion of a comprehensive FDA inspection of our manufacturing process In August 2023 FDA provided a complete response to Biologics License Application (BLA) resubmission for remestemcel-L for the treatment of pediatric SR-aGVHD. FDA provided a complete response requiring Mesoblast to demonstrate that product used in the phase 3 trial is similar to product intended for commercial release, as measured by a standardized potency assay FDA indicates that an additional clinical trial would be needed to establish this link if the company is not able to do so via additional potency assay work Type A meeting with FDA scheduled to be held mid-September Mesoblast proposes providing FDA with additional potency assay data to provide link between Phase 3 product and commercial inventory Mesoblast proposes providing FDA with new clinical trial data in adults, which could also support the pediatric indication Regulatory Status for Remestemcel-L in Pediatric Patients with SR-aGVHD Type A FDA Meeting Scheduled for mid-September
7 m e s o b l a s t In line with our overall commercial strategy to progress to adult patient populations, which make up approximately 5-fold larger numbers than children, Mesoblast intends to conduct a targeted, controlled study in adults with high mortality risk 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 days1,2 In contrast, 100-day survival was 63% after remestemcel-L treatment was used under expanded access in 71 patients aged 12 and older with SR-aGVHD who failed to respond to at least one additional agent, such as ruxolitinib Mesoblast is in discussions with world-leading investigators at the Blood and Marrow Clinical Trials Network (BM CTN), a body responsible for 80% of all US transplants, to conduct the new clinical trial The costs of this targeted study are expected to be covered by the planned spending reductions as outlined in the financial section Regulatory Status for Remestemcel-L in Patients with SR-aGVHD Generating New Clinical Data in Adults 1.

20 m e s o b l a s t Rexlemestrocel-L / CLBP – Program Summary Gained alignment with the FDA on the appropriate pivotal Phase 3 study Seeks to replicate the significant reduction in pain seen at 12 and 24 months in our first Phase 3 trial FDA has agreed with Mesoblast plans for mean pain reduction at 12 months as the primary endpoint of the pivotal trial Functional improvement and reduction in opioid use as secondary endpoints Product has been manufactured for use in the pivotal Phase 3 study Potency assays are in place for product release RMAT designation for CLBP received from FDA February 2023 Pivotal trial start-up activities have commenced and recruitment is expected to begin next quarter Pivotal P3 Trial Product Manufacturing Phase 3 Protocol Regulatory Alignment
21 m e s o b l a s t RMAT designation 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) Results from the trial showed that: A single injection of rexlemestrocel-L+HA into the lumbar disc resulted in significant reduction in pain compared with saline control at 12 and 24 months across all subjects (n=404) Pain reduction through 36 months was seen in the subset of patients using opioids at baseline (n=168) with the rexlemestrocel-L+HA group having substantially greater reduction at all time points compared with saline controls Among patients on opioids at baseline, despite instructions to maintain existing therapies throughout the trial, at 36 months 28% who received rexlemestrocel-L+HA were not taking an opioid compared with 8% of saline treated controls Regenerative Medicine Advanced Therapy (RMAT) Designation Granted by FDA for Rexlemestrocel-L in the treatment of CLBP
