Mesoblast Reports Financial Results and Operational Update for Fiscal Year Ended June 30, 2024

Potential first product approval and preparing for commercial launch

NEW 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 outreach
- Medical provides education to payers
- Corporate leadership initiates engagement with Top 15 centers
- Regional sales directors lead center profiling
- Ongoing KOL engagement with greatest experience using RYONCIL at highest volume centers
- Non-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).³
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. 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.⁴
In 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.

COST CONTAINMENT TARGETS ACHIEVED FOR FY2024 AND CONTINUING IN FY2025

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 FY2023.⁷
Research & 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.
