Heart failure NYHA class III

In its final analysis of Pfizer Inc. 's widely used drug for transthyroid amyloid cardiomyopathy (ATRCM), the U.S. drug cost regulator called for a reduction of at least 85 percent from its current list price of nearly $268,000 a year to meet generally accepted cost-effectiveness standards. The conclusion, made official in the latest ATRCM report released Monday by the Institute for Clinical and Economic Review (ICER), makes clear that Pfizer's two tafetamines, Vyndaqel and Vyndamax, are subject to the discount requirement. According to ICER's data analysis, in order to meet the cost-effectiveness criteria of between $100,000 and $150,000 per quality-adjusted life year (QALY) or equivalent life year acquired, the annual cost of Tarfamides and the thyrotropin stabilizer category to which it belongs should be adjusted to between $13,600 and $39,000. That means a price cut of between 85 and 95 per cent. The proposed annual cost range is revised up from a preliminary draft report in July. In its response, Pfizer reiterated the challenges and biases it faces in using QALEs as a cost-effectiveness measure for rare diseases, particularly for older patients who have a shorter life expectancy and limited time to benefit from treatment. In addition, the report comes at a time when the FDA is about to make a decision on BridgeBio Pharmaceuticals' competing drug acoramidis, and Alnylam Pharmaceuticals recently submitted an application for its RNA silencer Amvuttra (vutrisiran). This could further affect the competitive landscape of the ATRCM market. It is worth noting that ICER's price assessment covered Tafamidi and acoramidis, but did not include Amvuttra. Although Amvuttra was approved by the FDA for the treatment of ATR polyneuropathy in 2022 and has an annual price tag of $463,500, ICER said there is still not enough data to build an economic model for it. ICER's chief medical officer, Dr. David Rind, noted that the reasons for the price range adjustment include a change in the mortality estimate methodology and the correction of a calculation error in the previous quality of life assessment. At the same time, he highlighted the difficulty in economic evaluation of Amvuttra, especially the lack of data on the prediction of disease change in patients with NYHA Class III heart failure. However, he expects that the information may eventually be made public to meet the requirements of the European health assessment. In the final report, ICER also raised the complexity of comparing the net health benefits of Amvuttra versus stabilizers, noting that the question of the advantages of combination therapy versus monotherapy needs further study. To that end, the group recommends that researchers work to build a comparative profile of the three drugs and stresses the importance of randomized clinical trials to answer this question.

Potential first product approval and preparing for commercial launchNEW YORK, Aug. 28, 2024 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, today provided an operational update and reported financial results for the period ended June 30, 2024. Mesoblast Chief Executive Silviu Itescu said: “During the past year we have built significant momentum in our interactions with the United States Food and Drug Administration (FDA) across each of our Phase 3 products. I am very pleased that our Biologics License Application (BLA) resubmission for approval of Ryoncil® (remestemcel-L) in the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD) was accepted by the FDA. We are in active discussions with the agency and anticipate a decision prior to or on the Prescription Drug User Fee Act (PDUFA) goal date of January 7, 2025. Concurrently we are implementing a go-to-market plan to bring RYONCIL to the many children suffering with this devastating disease, picking up the substantial amount of work completed last year.” “We have commenced enrolling patients across multiple U.S. sites in our confirmatory Phase 3 trial for inflammatory back pain which is in alignment with FDA, we have received a Rare Pediatric Disease Designation from FDA for Revascor® (rexlemestrocel-L) in children with a congenital heart disease, and have additionally been notified that FDA supports a potential accelerated approval pathway for REVASCOR in end-stage heart failure patients.” OPERATIONAL RESULTS FOR THE FULL-YEAR ENDED JUNE 30, 2024 (FY2024) 1. RYONCIL (REMESTEMCEL-L) FOR ACUTE GRAFT VERSUS HOST DISEASE IN CHILDREN Potential FDA Approval Mesoblast resubmitted its BLA for approval of RYONCIL on July 8, 2024, addressing remaining CMC (Chemistry, Manufacturing, and Controls) items in the August 2023 Complete Response Letter (CRL).FDA previously informed Mesoblast that the available clinical data from its Phase 3 study appears sufficient to support resubmission of the BLA.FDA accepted the BLA resubmission within two weeks, considering it to be a complete response.Mesoblast and FDA are in ongoing interactions in relation to the active BLA review.FDA has already conducted the Pre-License Inspection (PLI) of the manufacturing process for RYONCIL in May 2023 and this did not result in the issuance of any Form 483.Mesoblast anticipates a decision prior to or on the FDA’s Prescription Drug User Fee Act (PDUFA) goal date of January 7, 2025. Activities For Go to Market Strategy Hiring of select senior positions to build targeted commercial team has commenced.Key Pre-Launch Activities include: Market Access initiates payer outreachMedical provides education to payersCorporate leadership initiates engagement with Top 15 centersRegional sales directors lead center profilingOngoing KOL engagement with greatest experience using RYONCIL at highest volume centersNon-promotional activities including profiling high-volume centers, education on disease awareness & unmet needs, and payer engagement Post-launch - Staged approach based on centers with highest volume and experience with product.Targeted sales force with experience in bone marrow transplant centers - 15 highest volume centers account for ~50% of patients. 2. RYONCIL (REMESTEMCEL-L) FOR ACUTE GRAFT VERSUS HOST DISEASE IN ADULTS Mesoblast strategy is to first gain pediatric approval for RYONCIL, followed by label extension in the larger adult population.As part of its label extension strategy for RYONCIL, Mesoblast is planning to conduct a study in the larger adult population once it has gained pediatric approval.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 67% after RYONCIL treatment was used under expanded access in 51 adults and children with SR-aGVHD who failed to respond to at least one additional agent, such as ruxolitinib.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. 3. REXLEMESTROCEL-L FOR CHRONIC LOW BACK PAIN ASSOCIATED WITH DEGENERATIVE DISC DISEASE The confirmatory Phase 3 trial of Mesoblast’s second generation allogeneic, STRO3-immunoselected, and industrially manufactured stromal cell product 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 at multiple sites across the United States.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 BLA. 4. REVASCOR (REXLEMESTROCEL-L) FOR PEDIATRIC CONGENITAL HEART DISEASE: HYPOPLASTIC LEFT HEART SYNDROME (HLHS) During the year FDA granted REVASCOR both Rare Pediatric Disease Designation (RPDD) and Orphan-Drug Designation (ODD). This followed submission of results from the randomized controlled trial in children with hypoplastic left heart syndrome (HLHS), a potentially life-threatening congenital heart condition.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).3In 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. Without full BiV conversion the right heart chamber is under excessive strain with increased risk of heart failure and death.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. 5. REVASCOR (REXLEMESTROCEL-L) FOR CHRONIC HEART FAILURE WITH REDUCED EJECTION FRACTION (HFrEF) AND PERSISTENT INFLAMMATION Heart failure with low ejection fraction (HFrEF) occurs in approximately 50% of all heart failure patients and is associated with high mortality.Over 60% of HFrEF patients have underlying ischemia and these are at highest risk of recurrent major adverse cardiac events involving large vessels (heart attacks / strokes).REVASCOR has reduced major adverse cardiac events (MACE) (cardiovascular death, heart attacks and strokes) in a completed randomized controlled Phase 3 trial in ischemic HFrEF patients with NYHA class II /III disease and inflammation.Over 100,000 patients in the US progress annually to end-stage HFrEF and more than 2,500 life prolonging LVADs are implanted annually in these patients.Resistance to functional recovery in ischemic HFrEF patients with LVADs is thought to be due to excessive inflammation and microvascular insufficiency in the ischemic myocardium.4In a randomized controlled trial, a single administration of REVASCOR reduced inflammation, strengthened left ventricular function, reduced right ventricular failure, and reduced hospitalizations in end-stage ischemic HFrEF patients with a left ventricular assist device (LVAD).In March FDA informed Mesoblast that it supports an accelerated approval pathway for its second generation allogeneic, STRO3-immunoselected, and industrially manufactured stromal cell product rexlemestrocel-L (Revascor®), for patients with end-stage ischemic HFrEF and an LVAD.Mesoblast has received RMAT designation for rexlemestrocel-L in the treatment of end-stage heart failure in LVAD patients and intends to meet with FDA to discuss data presentation, timing and FDA expectations for an accelerated approval filing in these patients. FINANCIAL RESULTS FOR THE FULL-YEAR ENDED JUNE 30, 2024 (FY2024) Cash balance at June 30, 2024 was US$63.3 million (A$95.0 million),5 with additional US$10.0 million available from an existing facility on FDA approval of RYONCIL.Reduction in net cash usage for operating activities: 23% reduction (US$14.8 million) for FY2024 compared with FY2023 (US$48.5 million vs US$63.3 million).37% reduction (US$6.1 million) for Q4 FY2024 compared with Q4 FY2023 (US$10.2 million vs US$16.3 million).Reduction in cash usage predominantly driven by reduced manufacturing activities and lowered payroll. Continued focus on prudent cash management for operational activities as we undertake targeted commercial rollout and supply chain activities for RYONCIL (remestemcel-L). COST CONTAINMENT TARGETS ACHIEVED FOR FY2024 AND CONTINUING IN FY2025 Achievement of 23% reduction (US$14.8 million) in net cash usage for operating activities in FY2024 was due in large part to successful execution of our payroll reduction strategy.Continued focus on cost containment of headcount and payroll to be maintained in FY2025.Alignment of management salaries and incentives with shareholders as outlined below. DETAILS OF FINANCIAL RESULTS FOR THE TWELVE MONTHS ENDED JUNE 30, 2024 (FY2024) Royalties primarily on sales of TEMCELL® HS Inj.6 sold in Japan by our licensee for the FY2024 were US$5.9 million and US$6.3 million on a constant currency basis, down 17% compared with US$7.1 million for the comparative period in FY2023.7Research & Development expenses reduced by US$1.8 million (7%), down to US$25.4 million for FY2024 compared with US$27.2 million for the comparative period in FY2023. R&D expenses primarily supported preparations for the remestemcel-L BLA re-submission and preparations for pivotal studies for CLBP associated with DDD and adult SR-aGVHD.Manufacturing reduced by US$12.0 million (43%), down from US$27.7 million to US$15.7 million due to decreased inventory build and one-off FY2023 spend on FDA Pre-License Inspection (PLI).Management and Administration expenses reduced by US$1.7 million (7%), to US$23.6 million for FY2024.Revaluation of Contingent Consideration recognized in FY2024 reflects a greater probability of approval of remestemcel-L for the treatment of SR-aGVHD as compared to FY2023 which reflected the 2023 CRL. In FY2024 we recognized a loss of US$9.7 million compared to a gain of US$8.8 million in FY2023.Fair value movement of warrants recognized a gain of US$0.8 million in FY2024 on a revaluation of warrants to market value compared to a loss of US$2.2 million in FY2023.Other operating income in FY2024 was US$2.6 million compared with US$4.2 million in FY2023 due to a reduction tax incentives.Finance Costs for borrowing arrangements include US$17.2 million of non-cash expenditure for FY2024 comprising accruing interest and borrowing costs. Loss after tax for FY2024 was US$88.0 million, a 7% increase compared to US$81.9 million for FY2023. The net loss attributable to ordinary shareholders was 8.91 US cents per share for FY2024, compared with 10.53 US cents per share for FY2023.

Ryoncil BLA Submission Under FDA Review for Approval in Children with SR-aGVHDNEW YORK, July 30, 2024 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, today provided highlights of its recent activities for the fourth quarter ended June 30, 2024. Mesoblast Chief Executive Silviu Itescu said: “We are very pleased with the strong relationship we have built with FDA across our product pipeline and the positive outcomes over the past six months.” “Our BLA resubmission for approval of Ryoncil® (remestemcel-L) in the treatment of children with acute graft versus host disease (SR-aGVHD) was accepted as a complete response, we received feedback from FDA on the potential accelerated approval pathway for Revascor® (rexlemestrocel-L) in end-stage heart failure patients, and our confirmatory Phase 3 trial in inflammatory back pain is actively enrolling with a primary endpoint of pain reduction aligned with FDA.” “We are executing on our go-to-market plan to bring Ryoncil to the many children suffering with the devastating disease of acute GVHD. I look forward to an activity update at our full year financials and investor call on August 28th 6.30pm EDT (August 29th 8.30am AEST).” KEY HIGHLIGHTS Graft versus Host Disease – Pending Decision on FDA Approval FDA informed Mesoblast 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 (RYONCIL) for treatment of pediatric patients with SR-aGVHD.Mesoblast resubmitted its BLA for approval of RYONCIL on July 8, 2024, addressing remaining CMC (Chemistry, Manufacturing, and Controls) items in the August 2023 Complete Response Letter (CRL).FDA accepted the BLA resubmission within two weeks, considering it to be a complete response.Mesoblast anticipates a decision prior to or on the FDA’s Prescription Drug User Fee Act (PDUFA) goal date of January 7, 2025.FDA has already conducted the Pre-License Inspection (PLI) of the manufacturing process for RYONCIL in May 2023 and this did not result in the issuance of any Form 483.RYONCIL is being reviewed under Priority Review, a designation given to drugs that treat a serious condition and provide a significant improvement in safety or effectiveness over existing treatments. Chronic Inflammatory Low Back Pain – Phase 3 Program The confirmatory Phase 3 trial of Mesoblast’s second generation 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.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). Chronic Heart Failure with Reduced Ejection Fraction (HFrEF) and Persistent Inflammation FDA informed Mesoblast that it supports an accelerated approval pathway for its second generation allogeneic, immunoselected, and industrially manufactured stromal cell product rexlemestrocel-L (Revascor®), for patients with end-stage ischemic heart failure with reduced ejection fraction (HFrEF) and a left ventricular assist device (LVAD).In these patients, a single administration of REVASCOR reduced inflammation, strengthened left ventricular function, reduced right ventricular failure, and reduced hospitalizations.REVASCOR has also reduced major adverse cardiac events (MACE) (cardiovascular death, heart attacks and strokes) in a completed Phase 3 trial in ischemic HFrEF patients with NYHA class II /III disease and inflammation.Mesoblast has received RMAT designation for rexlemestrocel-L in the treatment of end-stage heart failure in LVAD patients and intends to meet with FDA to discuss data presentation, timing and FDA expectations for an accelerated approval filing in these patients. FINANCIAL REPORT We will take a measured approach to preparing for the commercial launch of RYONCIL for treatment of children with SR-aGVHD in anticipation of potential FDA BLA approval and ensure prudent cash management. The successful implementation of the cost containment plan from August 2023 and the re-prioritization of projects has enabled us to reduce cash expenditure whilst still making significant strides forward on key programs as outlined above. We continue to work on corporate and strategic initiatives to access commercial distribution channels and optimize our balance sheet. Fourth Quarter and Full Year Results Cash balance at June 30, 2024 is US$63.0 million, with additional US$10.0 million available from an existing facility on FDA approval of RYONCIL.Net operating cash spend of US$10.2 million for the fourth quarter FY2024.37% (US$6.0 million) reduction in net operating cash spend for the fourth quarter FY2024 versus the prior comparative quarter in FY2023.23% (US$14.8 million) reduction in net operating cash spend in FY2024 compared to FY2023.

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, and biologic-resistant inflammatory bowel disease. Rexlemestrocel-L is being developed 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).
