Mesoblast Limited Achieves Patient Recruitment Target in Pivotal Phase 3 Trial for Chronic Low Back Pain Mesoblast Limited announced that its pivotal Phase 3 clinical trial evaluating rexlemestrocel-L for the treatment of chronic low back pain (CLBP) associated with degenerative disc disease has achieved its patient recruitment target. The placebo-controlled study (MSB-DR004) will follow at least 300 patients randomized to a single intra-discal injection of rexlemestrocel-L or sham control for 12 months. The trial seeks to confirm results from the earlier MSB-DR003 trial where a single intra-discal injection of rexlemestrocel-L resulted in clinically meaningful reductions in pain and opioid usage for up to three years. The trial’s primary endpoint is powered to show a significant difference in reduction of low back pain at 12 months between rexlemestrocel-L and sham controls. Secondary endpoints include improvements in function, quality of life, and cessation of pain medication, including opioids. Top-line results are expected in mid-CY2027 after the last randomized patient has completed follow-up. A positive readout will be used in support of an expected regulatory filing in Third Quarter CY2027 for United States Food and Drug Administration (FDA) approval. Rexlemestrocel-L has Regenerative Medicine Advanced Therapy (RMAT) designation from the FDA for treatment of CLBP due to degenerative disc disease providing eligibility for priority review once the Biologics License Application (BLA) has been filed. CLBP caused by inflammation and degenerative disc disease is a serious condition with a prevalence of over 7 million people in the U.S. alone. The indication is a potential blockbuster for Mesoblast with potential peak year revenue of >USD 10 billion with single digit market penetration. The 300-patient randomized controlled confirmatory Phase 3 trial of Mesoblast’s second generation allogeneic, STRO3-immunoselected, and industrially manufactured stromal cell product candidate rexlemestrocel-L in combination with hyaluronic acid (HA) as delivery agent for injection into the lumbar disc is actively enrolling in patients with chronic low back pain (CLBP) due to inflammatory degenerative disc disease (DDD) of less than five years duration at multiple sites across the U.S. 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 Regenerative Medicine Advanced Therapy (RMAT) for the treatment of chronic low back pain. 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). Back pain is the leading cause of disability in Americans under 45 years, with an annual prevalence in the general US adult population of 10-30%. CLBP caused by inflammation and degenerative disc disease (DDD) is a serious condition with a prevalence of over 7 million people in the US alone. CLBP due to DDD is a leading cause of disability, and is associated with impaired quality of life, severe limitations in ability to perform activities of daily living, reduced ability to work, and negative impacts on mental health. CLBP accounts for approximately 50% of prescription opioid usage in the US, making the condition a significant contributor to the opioid epidemic. お知らせ • Mar 12

Mesoblast Limited Provides Revenue Guidance for Fiscal Year 2026 Mesoblast Limited provided revenue guidance for fiscal year 2026. Mesoblast anticipates full-year fiscal 2026 Ryoncil net revenue to range between USD 110 million and USD 120 million. お知らせ • Feb 12
Mesoblast Limited Provides Data Presented at the February 2026 Tandem Meetings of the American Society for Transplantation and Cellular Therapy and the Center for Blood and Marrow Transplant Research in Salt Lake City, Utah Mesoblast Limited provided data presented at the February 2026 Tandem Meetings of the American Society for Transplantation and Cellular Therapy (ASTCT) and the Center for Blood and Marrow Transplant Research (CIBMTR) in Salt Lake City, Utah. The study results showed that Ryoncil®? (remestemcel-L-rknd) achieved similarly high survival outcomes in steroid-refractory acute graft-versus-host disease (SR-aGvHD) irrespective whether used in children or adults, as second or third line, and in ruxolitinib naive or resistant patients. Ryoncil®? is the first mesenchymal stromal cell (MSC) product approved by the U.S. Food and Drug Administration (FDA) for any indication, and the only product approved for children under age 12 with steroid-refractory acuteraft-versus-host disease ("SR-aGvHD"). Importantly, of the 53 patients with SR-aGvHD who received Ryoncil®? as third line treatment under the Emergency Investigational New Drug (EIND) program (89% grade III/IV disease), 15% died before being able to complete a full treatment course of Ryoncil®? compared with only 2% of patients who received Ryoncil®®? as second-line in the Phase 3 trial MSB-GVHD001. These results emphasize the importance of using Ryoncil®? as early as possible after steroid resistance in acute GVHD in order to complete a full treatment course and maximize survival. Additionally, adult patients in the EIND program of Ryoncil®? had at least as favorable day 100 survival as children in the EIND program, providing strong support and rationale for the planned pivotal trial of early use of Ryoncil®? as part of the second-line treatment regimen in adults with severe SR-aGvHD. The trial is expected to commence enrollment this quarter after protocol approval by the trial's central Institutional Review Board (IRB). If successful, the trial will support label extension of Ryoncil® for use in adults - a population approximately three times the size of the pediatric SR-aGvHD population. お知らせ • Jan 27
Mesoblast Limited Announces Update on Ryoncil (remestemcel-L-rknd) for Pediatric SR-aGvHD and Plans for Adult Trials Mesoblast Limited provided an update on use of Ryoncil (remestemcel-L-rknd) since commercially available in March 2025 for the approved label in children 2 months and older with steroid-refractory acute graft-versus-host disease (SR-aGvHD). Ryoncil is the first mesenchymal stromal cell (MSC) product approved by the U.S. Food & Drug Administration (FDA) for any indication. Of the first 25 patients treated with Ryoncil in a 'real-world' clinical setting post launch, 21 were alive (84%) and completed the initial 28-day treatment regimen as per the FDA approval label. The four patients who did not complete the 28-day treatment course had been offered and failed other therapies prior to use of Ryoncil and died of severe SR-aGvHD within 28 days. To ensure that no patient is left behind in receiving this potentially life-saving therapy, Mesoblast has established a patient access hub termed MyMesoblast, where Ryoncil is available for ordering. To date 45 transplant centers have been onboarded, with a target of 64 centers which account for 94% of transplantants performed in the U.S. Ryoncil coverage by government and commercial payers already extends to over 260 million U.S. lives with Federal Medicaid coverage by U.S. Centers for Medicare & Medicaid Services (CMS) and mandatory fee-for-service Medicaid coverage in all U.S. states. Issuance on October 1, 2025, of a specific Healthcare Common Procedure Coding System (HCPCS) J-Code by CMS for billing and reimbursement resulted in greater usage of Ryoncil under CMS coverage versus commercial coverage in the last quarter. These commercial activities will continue to serve the company well as it seeks to expand the FDA label for Ryoncil to adults with severe SR-aGv HD, a market size approximately three times that of the pediatric SR-aGvHD population. A pivotal trial of Ryoncil in adults with severe SR-a GvHD will be conducted with the NIH-funded Bone Marrow Transplant Clinical Trials Network (BMT-CTN) and is expected to commence site enrollment this quarter. お知らせ • Jan 21
Mesoblast Limited Provides Feedback Received from the U.S. Food & Drug Administration on Potential Filing of a Biologics License Application for its Allogeneic Cell Therapy Product Rexlemestrocel-L in Patients with Chronic Low Back Pain Mesoblast Limited provided feedback received from the U.S. Food & Drug Administration (FDA) on potential filing of a Biologics License Application (BLA) for its allogeneic cell therapy product rexlemestrocel-L in patients with chronic discogenic low back pain (CLBP). This follows FDA's Type B meeting review of data from Mesoblast's first randomized controlled Phase 3 trial (MSB-DR003) on pain reduction and relationship to decreased use or elimination of opioids for up to three years following a single rexmestrocel-L administration. Mesoblast is seeking FDA approval for rexlemestrocel- L based on reduction in CLBP through 12 months. Comparing outcomes between rexlemestrocel- Ltd. and placebo from MSB-DR003 trial, FDA acknowledged that the effects on pain intensity appear to favor the active arm. FDA also confirmed that a clinically meaningful reduction in pain intensity in the active arm versus placebo at 12 months can support product efficacy and stated that the robust results on opioid reduction from at least one adequate and well controlled trial could be included in the Clinical Studies section of product labeling. CLBP is a major contributing factor to the U.S. opioid crisis, and rexlemestrocel-l has received Regenerative Medicine Advanced Therapy (RMAT) designation from FDA for treatment of CLBP. The 300-patient randomized controlled confirmatory Phase 3 trial of Mesoblast's second generation allogeneic, STRO3-immunoselected, and industryally manufactured stromal cell product candidate rexlemestrocel- lumbar disc is actively enrolling in patients with chronic low back pain (CLBP) due to inflammatory degenerative disc disease (DDD) of less than five years duration at multiple sites across the U.S. 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 effective indication. In light of the devastating opioid crisis that continues to rage in the U.S., in September 2025 FDA provided new Guidance to Industry on Development of Non-Opioid Agents for Treatment of Chronic Pain. Significant pain reduction and opioid cessation were observed in Mesoblast's first Phase 3 trial. FDA has designated rexlemestrocel-S a Regenerative Medicine Advanced Therapy (RMAT) for the treatment of chronic low back pain. The therapies from the Company's proprietary mesenchymal line 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-rknd) 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 FDA-approved mesenchymal stromal cell (MSC) therapy.

Mesoblast Limited’s RYONCIL® is the First U.S. FDA-Approves Mesenchymal Stromal Cell (MSC) Therapy Mesoblast Limited announced the Food and Drug Administration (FDA) approved Ryoncil (remestemcel-L) as the first mesenchymal stromal cell (MSC) therapy in the United States. RYONCIL is the only MSC therapy approved in the U.S. for any indication, and the only approved therapy for steroid-refractory acute graft versus host disease (SR-aGvHD) in children 2 months and older, including adolescents and teenagers. Annually in the United States approximately 10,000 patients undergo an allogeneic bone marrow transplant, 1,500 of whom are children. Approximately 50% develop aGvHD and almost half of those do not respond to steroids, the recognized first-line treatment. In a single-arm multi-center Phase 3 trial of children with SR-aGvHD, 89% of whom had high severity Grade C or Grade D disease, 70% achieved an overall response by Day 28 of treatment with RYONCIL, a measure that predicts survival in aGVHD. RYONCIL treatment was not discontinued or interrupted in any patient for any laboratory abnormality, and the full course was completed without interruption in more than 85% of patients. The full Phase 3 clinical study results are available in Biology of Blood and Marrow Transplantation. お知らせ • Dec 05
FDA Grants Revascor (Rexlemestrocel-L) Regenerative Medicine Advanced Therapy (RMAT) Designation in Children with Congenital Heart Disease Mesoblast Limited announced the United States Food and Drug Administration (FDA) has granted its second generation allogeneic, STRO3-immunoselected, and industrially manufactured stromal cell therapy Revascor (rexlemestrocel-L) Regenerative Medicine Advanced Therapy (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 this year, FDA granted REVASCOR both Rare Pediatric Disease Designation (RPDD) and Orphan-Drug Designation (ODD) for treatment of children with HLHS. RPDD demonstrates that the disease is serious or life-threatening and the manifestations primarily affect individuals aged from birth to 18 years, including age groups often called neonates, infants, children, and adolescents, and that the disease is a rare disease or condition. On FDA approval of a BLA for REVASCOR for the treatment of HLHS, 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. 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 drug 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). Results from a blinded, randomized, placebo-controlled prospective trial of REVASCOR conducted in the United States in children with HLHS were published in the December 2023 issue of the peer reviewed The Journal of Thoracic and Cardiovascular Surgery Open (JTCVS Open). In the HLHS trial conducted in 19 children, a single intramyocardial administration of REVASCOR at the time of staged surgery resulted in the desired outcome of significantly larger increases in left ventricular (LV) end-systolic and end-diastolic volumes over 12 months compared with controls as measured by 3D echocardiography, (p=0.009 & p=0.020 respectively). 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 andrexlemestrocel-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, and biologic-resistant inflammatory bowel disease. Forward-looking statements include, but are not limited to, statements about: the initiation, timing, progress and results of Mesoblast's preclinical and clinical studies, and Mesoblast's research and development programs; Mesoblast's ability to advance product candidates into, enroll and successfully complete, clinical studies, including multi-national clinical trials; Mesoblast's ability To advance its manufacturing capabilities; the timing or likelihood of regulatory filings and approvals (including any future decision that the FDA may make on the BLA for remestemcel-L for pediatric patients with SR-aGVHD), manufacturing activities and product marketing activities, if any; the commercialization of Mesoblast's product candidates, if approved; regulatory or public approval of the RMAT designation, the company's approval of the RMAT designation. お知らせ • Dec 03
Mesoblast Limited Announces Publication in the November 2024 Online Issue of the European Journal of Heart Failure Mesoblast Limited announced a key publication in the November 2024 online issue of the prestigious peer-reviewed European Journal of Heart Failure (EJHF), which reports that a single intramyocardial injection of the Company's allogeneic cell therapy Revascor®? (rexlemestrocel-L) results in improved survival in high-risk patients with ischemic heart failure and inflammation. Results from the randomized, controlled DREAM-HF trial in patients with chronic heart failure with reduced injection fraction (HFrEF) identified the control group at highest risk of cardiovascular death as being those with ischemic etiology and inflammation and showed that a single intramy Cardial injection of Mesoblast's mesenchymal precursor cell therapy (MPCs; rexlemestrocel-L) resulted in a sustained reduction in cardiovascular mortality in these high-risk patients. This identifies the target HFrEF population that is responsive to REVASCOR therapy. The newly published results showed that over a mean follow-up of 30 months in the DREAM-HF trial: Factors portending the greatest risk for cardiovascular death in control patients were inflammation (baseline plasma high-sensitivity C-reactive protein =2 mg/L; p=0.003) and ischemic HFrEF etiology (p=0.097), with increased cardiovascular death risk of 61% and 38%, respectively. A single intra-myocardial MPC administration significantly lowered the risk of cardiovascular death in HFrEF patients with inflammation regardless of whether plasma hsCRP or plasma IL-6 was used as inflammatory biomarker by 80% (p=0.003) and 60% (p=0.037) respectively. MPCs reduced 2-point MACE (heart attack or stroke) by 57% (p=0.016) and 3-point MACE (cardiovascular death, heart attack, stroke) by 35% (p=0.049) in patients with ischemic HFrEF (n=303) compared to controls. MPCs reduced 2-point and 3-point MACE by 88% (p=0.005) and 52% (p=0.018) respectively, in patients with ischemic HFrEF and inflammation (n=158) compared to controls. お知らせ • Oct 17

Mesoblast Limited Announces the United States Food and Drug Administration Has Accepted Its Biologics License Application (Bla) Resubmission for Ryoncil® Mesoblast Limited announced that the United States Food and Drug Administration (FDA) has accepted its Biologics License Application (BLA) resubmission for Ryoncil® (remestemcel-L) in the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD). FDA considers the resubmission to be a complete response and Mesoblast anticipates a decision on or before the FDA’s Prescription Drug User Fee Act (PDUFA) goal date of January 7, 2025. Mesoblast’s resubmission on July 8, 2024 addressed remaining CMC (Chemistry, Manufacturing, and Control) items after being informed by FDA at the end of March 2024 that, following additional consideration, the available clinical data from the Phase 3 study MSB-GVHD001 appears sufficient to support submission of the proposed BLA for remestemcel-L for treatment of pediatric patients with SR-aGVHD. In May 2023, FDA conducted the Pre-License Inspection (PLI) of the manufacturing process for remestemcel-L, and this did not result in the issuance of any Form 483. Mesoblast’s lead product candidate, Ryoncil® (remestemcel-L), is an investigational therapy comprising culture expanded mesenchymal stromal cells derived from the bone marrow of an unrelated donor. It is administered to patients in a series of intravenous infusions. RYONCIL has immunomodulatory properties which counteract the inflammatory processes that are implicated in SR-aGVHD by inhibiting activation and proliferation of effector T cells, down-regulating the production of pro-inflammatory cytokines, and enabling recruitment of anti-inflammatory cells to involved tissues. FDA granted remestemcel-L Fast Track designation, a process to facilitate the development and expedited review of therapies for serious conditions that fill unmet medical needs, and Priority Review designation, which is given to drugs that treat a serious condition and provide a significant improvement in safety or effectiveness over existing treatments. The Phase 3 Study GVHD001/002 was conducted in 54 children (89% Grade C/D) across 20 centers in the US where RYONCIL was used as the first line of treatment for children who failed to respond to steroids for acute GVHD.1 The trial met its pre-specified primary endpoint, Day 28 Overall Response (OR), 70.4% versus 45%, p=0.0003. An overall response at day 28 was highly predictive of improved survival through day 100 (87% compared to 47% in patients that did not achieve day 28 OR p= 0.0001). Compared with a matched control group of pediatric subjects from the contemporaneous database of the Mount Sinai Acute GVHD International Consortium (MAGIC) treated with best available therapy, treatment with Ryoncil achieved higher Day 28 OR (70% vs 43%) and higher Day 100 survival (74% vs 57%). A propensity-matched study of outcomes in 25 children from Mesoblast’s Phase 3 trial and 27 control children who received best available treatment, including ruxolitinib, from the MAGIC database showed that 67% of high-risk children (MAP scores >0.29) who received Ryoncil achieved a Day 28 overall response and were alive after 180 days compared to just 10% in both categories in the MAGIC group. In addition, results of a 4-year survival study performed by the Center for International Blood and Marrow Transplant Research (CIBMTR) on 51 evaluable patients with SR-aGVHD who were enrolled in the Phase 3 trial, demonstrated durability of the survival benefits, with 67% survival at 6 months, 63% survival at 1 year, 51% at 2 years, and 49% survival through 4 years in children with expected 2 year survival of just 25-38% using best available therapy. Acute GVHD occurs in approximately 50% of patients who receive an allogeneic bone marrow transplant (BMT). Over 30,000 patients worldwide undergo an allogeneic BMT annually, primarily during treatment for blood cancers, including about 20% in pediatric patients.5,6 SR-aGVHD is associated with mortality as high as 90% and significant extended hospital stay costs.7,8 There are currently no FDA-approved treatments in the US for children under 12 with SR-aGVHD. Survival outcomes have not improved over the past two decades for children or adults with the most severe forms of SR-aGVHD.2,9-10 The lack of any approved treatments for children under 12 means that there is an urgent need for a therapy that improves the dismal survival outcomes in children. お知らせ • Jul 22
Mesoblast Limited Announces Patient Enrollment Commences in Pivotal Phase 3 Trial of Rexlemestrocel-L for Chronic Low Back Pain Mesoblast Limited announced that the confirmatory Phase 3 trial of its allogeneic, immunoselected, and industrially manufactured stromal cell product rexlemestrocel-L in patients with chronic low back pain (CLBP) due to inflammatory degenerative disc disease of less than five years duration has commenced enrollment at multiple sites across the United States. The United States Food and Drug Administration (FDA) has previously confirmed alignment with Mesoblast on the design of the 300-patient randomized, placebo-controlled trial and the 12-month primary endpoint of pain reduction as an approvable indication. Key secondary measures include improvement in quality of life, function, and reduced opioid usage. FDA has designated rexlemestrocel-L a Regenerative Medicine Advanced Therapy (RMAT) for the treatment of chronic low back pain. 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). お知らせ • Jul 10

Mesoblast Limited Announces United States Food & Drug Administration Supports Accelerated Approval Pathway for Rexlemestrocel-L in End-Stage Heart Failure Patients with A Left Ventricular Assist Device Mesoblast Limited announced that U.S. FDA supports an accelerated approval pathway for rexlemestrocel-L, Mesoblast's allogeneic mesenchymal precursor cell (MPC) product, in patients with end-stage ischemic heart failure with reduced ejection fraction (HFrEF) and a left ventricular assist device (LVAD). FDA provided this feedback in formal minutes to the company following the Type B meeting held with FDA on February 21, 2024 for rexmestrocel-L (Revascor®?) under the existing Regenerative Medicine Advanced Therapy (RMAT) designation. Every year in the United States over 100,000 patients progress to end-stage HFrEF. Only 4.9% of ischemic patients treated with a single administration of rexlemestrocel- Ltd. died from month 2 through month 12, as compared with 26.9% of ische Micmic controls, an 82% reduction (p = 0.02). In feedback provided to Mesoblast regarding potential pathways to licensure for rexlemestrocel -L, FDA's comments indicated that the presented results may support a reasonable likelihood of clinical benefit of MPCs against mortality in LVAD patients, consistent with the criteria for accelerated approval. Mesoblast intends to request a pre-BLA meeting with FDA to discuss data presentation, timing and FDA expectations for an accelerated approval filing in end-stage ischemic HFrEF patients with LVAD implantation. REVASCOR is an allogeneic preparation of immunoselected and culture-expanded mesenchymal precursor cells (MPC) and is being developed as an immunomodulatory therapy to address the high degree of inflammation in the heart and in the circulation that is present across the spectrum of heart failure and reduced ejection fraction (H FrEF) patients, from New York Heart Association (NYHA) class II through end-stage CHF, in order to reduce the high rate of major cardiac events and complications. This investigational therapy has been trialled in two large placebo-controlled randomized studies in patients with CHF, a 565-patient trial in NYHA class II/III HFrEF patients and a 159-patient trial in end-stage HFrEF patients implanted with a left ventricular assist device ("LVAD"). Rexlemestrocel-L has US Food and Drug Administration (FDA) Regenerative Medicine Advanced Therapy (RMAT) and Orphan Drug designations for patients with end-stage HFrEF implanted with an LVAD. Chronic heart failure (CHF) is characterized by poor heart function resulting in insufficient blood flow to the body's vital organs and extremities. 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 andrexlemestrocel-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. Forward-looking statements include, but are not limited to, statements about: the initiation, timing, progress and results of Mesoblast's preclinical and clinical studies, and Mesoblast's research and development programs; Mesoblast's ability to advance product candidates into, enroll and successfully complete, clinical studies, including multi-national clinical trials; Mesoblast's ability To advance its manufacturing capabilities; the timing or likelihood of patients with LVAD's ability to advance its manufacturing capabilities. お知らせ • Jan 19
United States Food & Drug Administration Grants Mesoblast Rare Pediatric Disease Designation for Revascor®? (Rexlemestrocel-L) in Children with Congenital Heart Disease Mesoblast Limited announced that the United States Food and Drug Administration (FDA) has granted its allogeneic cell therapy Revascor® (rexlemestrocel-L) a Rare Pediatric Disease (RPD) 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. RPD Designation is granted by the FDA for certain serious or life-threatening diseases which primarily affect children. On FDA approval of a Biologics Licensing Application (BLA) for REVASCOR for the treatment of HLHS, 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. Results from a blinded, randomized, placebo-controlled prospective trial of REVASCOR conducted in the United States in children with HLHS were published in the December 2023 issue of the peer reviewed The Journal of Thoracic and Cardiovascular Surgery Open (JTCVS Open). In the HLHS trial conducted in 19 children, a single intramyocardial administration of REVASCOR at the time of staged surgery resulted in the desired outcome of significantly larger increases in left ventricular (LV) end-systolic and end-diastolic volumes over 12 months compared with controls as measured by 3D echocardiography, (p=0.009 & p=0.020 respectively). These changes are indicative of clinically important growth of the small left ventricle, facilitating the ability to have a successful surgical correction, known as full biventricular (BiV) conversion, which allows for a normal two ventricle circulation with the surgically repaired left ventricle taking over circulatory supportto the body. Without full BiV conversion the right heart chamber is under excessive strain with increased risk of heart failure and death. お知らせ • Oct 30

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 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. お知らせ • Aug 04
Mesoblast Limited Receives Complete Response from U.S. Food and Drug Administration for Biologics License Application for Steroid-Refractory Acute Graft Versus Host Disease in Children Mesoblast Limited announced that the US Food and Drug Administration (FDA) has provided a complete response to its Biologics License Application (BLA) resubmission for remestemcel-L for the treatment of pediatric steroid-refractory acute graft versus host disease (SR-aGVHD) and requires more data to support marketing approval. To obtain the data required, Mesoblast will conduct a targeted, controlled study in the highest-risk adults with the greatest mortality. This adult study is in line with its overall commercial strategy, which envisioned a sequenced progression from pediatric to adult SR-aGVHD indications. Adults comprise 80% of the SR-aGVHD market. Mesoblast intends to enroll adult patients at highest mortality risk with SR-aGVHD where existing therapy has not improved outcomes and 90-day survival remains as low as 20-30%. Mesoblast has generated pilot data through its emergency IND program in adults showing a survival benefit with remestemcel-L in this target population. In line with its overall commercial strategy to expand into the adult SR-aGVHD indication, Mesoblast has already been working with leading investigators at various US centers of excellence to establish the adult follow-on study protocol, potentially utilizing established clinical trials networks. The company will seek alignment with FDA on the trial design for the adult study at a Type A meeting within 45 days. Prior to the resubmission, FDA guided Mesoblast to resolve outstanding chemistry, manufacturing and controls (CMC) issues before initiating any additional clinical trial. FDA completed the Pre-License Inspection (PLI) of the manufacturing facility, did not issue any Form 483, and found no objectionable conditions. In addition, FDA acknowledged in the resubmission review that changes implemented appear to improve assay performance relative to the original version of the assay used in the pediatric Phase 3 trial. Mesoblast has successfully met the pre-specified primary endpoint, prospectively agreed with FDA, of a single-arm Phase 3 trial in 54 children with SR-aGvHD. While the Oncologic Drugs Advisory Committee of FDA in August 2020 voted 9:1 in favor of remestemcel-L’s efficacy in a pediatric patient population, in September 2020 FDA recommended further steps be undertaken to obtain approval. The BLA resubmission of January 2023 included long-term follow-up data from the Phase 3 trial by the Center for International Blood and Marrow Transplant Research (CIBMTR) showing 50% survival through more than 4 years of follow-up for remestemcel-L treated patients in the Phase 3 trial for whom less than 20% survival at two years was expected based on disease severity. The resubmission also included a post-hoc propensity matched study showing 6 month survival was 67% with remestemcel-L vs 10% with other unapproved therapies in highest-risk patients as identified using the Mount Sinai Acute GVHD International Consortium (MAGIC). These pediatric data provide further support for use of remestemcel-L in the proposed study in high-risk adults with SR-aGVHD. お知らせ • Jun 05
Mesoblast Limited Appoints Dr. Philip R. Krause, Member of the Board of Directors, to Formal Strategic Advisory Role Mesoblast Limited announced that it has appointed Dr. Philip R. Krause, a member of the Board of Directors, to a formal strategic advisory role. Dr. Krause was formerly Deputy Director of the Office of Vaccines Research and Review at the US Food and Drug Administration (FDA) Center for Biologics Evaluation and Research (CBER) and is an internationally recognized expert on development and regulatory aspects of biologic products. Dr. Krause will advise the company on its regulatory strategies related to broadening out the remestemcel-L platform, including the ground-breaking treatment for steroid-refractory acute graft versus host disease (SR-aGVHD), inflammatory bowel disease and inflammatory lung disease, and the second-generation platform rexlemestrocel-L, including the Phase 3 product candidates for discogenic chronic lower back pain and inflammatory heart failure. お知らせ • Feb 17
Remestemcel-L Clinical and Potency Studies Presented At Premier Meeting of Transplantation Research and Therapy Mesoblast Limited announced that two studies on the remestemcel-L development program for the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD) were selected by peerreview to be presented at the 2023 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 15-19 in Orlando, Florida. The data from both studies formed key components of Mesoblast's recent resubmission of its remestemcel-L Biologics License Application (BLA) to U.S. Food and Drug Administration (FDA) for children with SR-aGVHD. Survival outcomes have not improved over the past two decades for the most severe forms of SR-aGVHD, a life-threatening complication of an allogeneic bone marrow transplant following treatment for blood cancers and other conditions.(1-) (3) The lack of any approved treatments for children under 12 means that there is an urgent need for a therapy that improves the dismal survival outcomes. If remestemcel-L receives FDA approval, it will be the first allogeneic "off-the-shelf" cellular medicine to be approved in the United States, and the first therapy for children under 12 years old with SR-aGVHD. お知らせ • Feb 09
Mesoblast Limited Announces FDA Grants Regenerative Medicine Advanced Therapy Designation for Rexlemestrocel-L in Chronic Low Back Pain Mesoblast Limited announced that the United States Food and Drug Administration’s Office of Tissues and Advanced Therapies has granted Regenerative Medicine Advanced Therapy designation for rexlemestrocel-L in the treatment of chronic low back pain associated with disc degeneration, in combination with hyaluronic acid as delivery agent for injection into the lumbar disc. 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 drug 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). There is a significant need for a safe, effective, and durable opioid-sparing treatment in patients with CLBP associated with degenerative disc disease. Data from the completed 404-patient randomized, blinded placebo-controlled Phase 3 trial of rexlemestrocel-L combined with HA formed the basis for FDA’s determination that Mesoblast’s allogeneic cell therapy has the potential to address unmet medical needs for patients suffering from CLBP due to disc degeneration. 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): The reduction in low back pain observed in all subjects was substantially enhanced in the pre-specified population with CLBP of shorter duration than the median of 68 months for the study (n=194). Significant improvement in function and quality of life measures were observed in subjects with a shorter duration of CLBP at baseline. 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. お知らせ • Feb 01
Mesoblast Limited Resubmits Biologic License Application to FDA for Remestemcel-L in Children With Steroid-Refractory Acute Graft Versus Host Disease (Sr-aGVHD) Mesoblast Limited announced it has resubmitted to the U.S. Food and Drug Administration (FDA) its Biologics License Application (BLA) for approval of remestemcel-L in the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD). Survival outcomes have not improved over the past two decades for the most severe forms of SR-aGVHD, a life-threatening complication of an allogeneic bone marrow transplant following treatment for blood cancers and other conditions.1-3 The lack of any approved treatments for children under 12 means that there is an urgent need for a therapy that improves the dismal survival outcomes. If remestemcel-L receives FDA approval, it will be the first allogeneic “off-the-shelf” cellular medicine to be approved in the United States, and the first therapy for children under 12 years old with SR-aGVHD. The resubmission contains substantial new information as required by FDA in the Complete Response Letter (CRL) received in September 2020 to the BLA for remestemcel-L. Mesoblast has maintained an active dialogue with FDA since receiving the CRL and in October 2022 provided a high-level synopsis of the substantial new information under its Investigational New Drug (IND) application for remestemcel-L. FDA granted remestemcel-L Fast Track designation, a process to facilitate the development and expedited review of therapies for serious conditions that fill unmet medical needs, and Priority Review designation, which is given to drugs that treat a serious condition and provide a significant improvement in safety or effectiveness over existing treatments. The BLA resubmission will have a review period up to six months from filing upon acceptance by FDA. Mesoblast has responded to the CRL and the further guidance it has received from the FDA and has generated and provided new data and analyses in the resubmission which company believe provide substantial evidence of remestemcel-L's effectiveness in pediatric SR-aGVHD. Specifically, the resubmission contains the following: new long-term survival data of children enrolled in the Phase 3 trial showing durability of treatment effect through at least four years, new data showing remestemcel-L’s treatment benefit in high-risk disease activity and on survival in propensity-matched studies of children in the Phase 3 trial and controls stratified by validated biomarkers for high-risk disease, new analyses of data obtained prospectively showing that the validated potency assay which was in place and used to release product for the 54-patient Phase 3 clinical trial measures a key product attribute which reflects the primary mechanism of action of remestemcel-L in children with SR-aGVHD, correlates with the product’s in vivo bioactivity, and predicts overall survival outcomes, new analyses of data obtained prospectively relating manufacturing changes during product development prior to Phase 3 to progressive increases in potency and to improved survival outcomes in larger studies of remestemcel-L under expanded access in children with SR-aGVHD, new data showing that the validated potency assay has low variability and can adequately demonstrate manufacturing consistency and reproducibility, and establishment of a new specification for release of commercial product based on extensive clinical data which provides assurance that future batches of remestemcel-L will have attributes supportive of expected survival outcomes.
