Mesoblast Limited announced FDA clearance to proceed directly to a registrational clinical trial for Ryoncil® (remestemcel-L-rknd) in Duchenne muscular dystrophy (DMD). The trial will randomize 76 patients aged 5-9 years to receive either Ryoncil® or placebo over 9 months, with time-to-stand at nine months as the primary endpoint. The company is partnering with Parent Project Muscular Dystrophy to support patient identification and trial awareness.

Mesoblast Limited announced Q1 2026 net sales of US$30.3 million for Ryoncil (remestemcel-L-rknd), its FDA-approved mesenchymal stromal cell therapy for steroid-refractory acute graft-versus-host disease in children. Strong February and March sales offset January seasonality, with first-year revenue approaching US$100 million since launch. The company will host an inaugural R&D Day on April 8, 2026, to outline growth strategy and late-stage pipeline programs.

Avaí Bio announced it has initiated manufacturing of a Master Cell Bank of genetically modified cells that overexpress the α-Klotho protein, a key anti-aging protein that naturally declines by 50% after age 40. The milestone represents a transition from research to production infrastructure for their Klothonova anti-aging platform using Cell-in-a-Box® encapsulation technology. The cell therapy sector is rapidly expanding, with the global market projected to grow from $10.4 billion to over $45 billion by 2035.

Mesoblast Limited announced its inaugural R&D Day scheduled for April 8, 2026 in New York City. The event will feature presentations on the company's corporate strategy, commercialization of its flagship product Ryoncil®, and its pipeline opportunities in inflammatory pain and cardiovascular disease. The company will also unveil new technology for cellular medicines innovation.

Mesoblast Limited announced the appointment of Teresa Montagut MD, PhD as Head of Clinical Development and Medical Affairs, a newly created position reporting to the Chief Medical Officer. Montagut brings extensive experience from Regeneron, Novartis, Genentech, and Atara Biotherapeutics, and will lead efforts to expand Ryoncil® indications in pediatric and adult inflammatory conditions and advance the company's cell therapy pipeline.

The global cell therapy market is projected to surpass $8.2 billion in 2026, with CAR T-cell therapy expanding at 18% annually. Several companies are advancing manufacturing milestones and clinical breakthroughs: Avaí Bio initiated Master Cell Bank production for α-Klotho anti-aging therapy; FibroBiologics secured a patent for fibroblast cell therapy for osteoporosis; Fate Therapeutics achieved same-day hospital discharge for off-the-shelf CAR T-cell patients; Mesoblast presented favorable survival data for Ryoncil® in graft-versus-host disease; and Longeveron published Phase 2b results showing stem cell therapy improved physical condition in age-related frailty patients.

Mesoblast Limited reported H1 FY2026 financial results showing significant improvement with total revenue of US$51.3 million, primarily driven by successful U.S. commercial launch of Ryoncil®. The company generated US$48.7 million in product revenue with gross profit of US$44.2 million. Net loss improved to US$40.2 million from US$47.9 million year-over-year. Mesoblast has onboarded 49 transplant centers toward a target of 64, secured coverage for 280 million U.S. lives, and is advancing pipeline programs including Phase 3 trials for chronic low back pain and heart failure indications. Full-year FY2026 Ryoncil® revenue guidance is US$110-120 million.

Mesoblast reported that Ryoncil® (remestemcel-L-rknd), the first FDA-approved mesenchymal stromal cell therapy, achieved high survival outcomes in steroid-refractory acute graft-versus-host disease across children and adults in an EIND program. Data showed 15% mortality in third-line patients versus 2% in second-line Phase 3 trial patients, emphasizing the importance of earlier treatment initiation. The company plans to commence a pivotal Phase 3 trial in adults this quarter, potentially supporting label extension to a population three times larger than the pediatric market.

Mesoblast Limited reported a 60% quarter-over-quarter increase in Ryoncil gross sales to US$35 million for Q2 FY2026. Real-world data showed 84% survival rate in pediatric SR-aGvHD patients completing 28-day treatment. The company secured a new US$125 million non-dilutive credit facility at 8% interest and received positive FDA feedback on rexlemestrocel-L for chronic low back pain, with a Phase 3 confirmatory trial actively recruiting.

Mesoblast reported that 84% of the first 25 children treated with Ryoncil® (remestemcel-L-rknd) in real-world clinical settings completed the initial 28-day treatment regimen for steroid-refractory acute graft-versus-host disease. The company has onboarded 45 transplant centers with a target of 64, and has secured coverage extending to over 260 million U.S. lives. A pivotal trial in adults with severe SR-aGvHD is expected to commence enrollment this quarter.

The FDA provided positive feedback on Mesoblast's rexlemestrocel-L, an allogeneic cell therapy for chronic discogenic low back pain, acknowledging that pain reduction effects favor the active treatment over placebo at 12 months. The FDA confirmed this clinically meaningful reduction can support product efficacy and that opioid reduction results can be included in product labeling. A second Phase 3 trial (MSB-DR004) is over 50% enrolled with completion expected within three months.

Mesoblast Limited reported gross revenue of US$35.1 million for Ryoncil® in Q2 2025, representing a 60% increase from the prior quarter. The company secured a new US$125 million five-year facility with substantially lower costs, enabling repayment of prior senior debt and providing flexibility for strategic partnerships and label expansion efforts.
