About this update from Maat Pharma
LYON, France, May 12, 2025 --( BUSINESS WIRE )--Regulatory News: MaaT Pharma (EURONEXT: MAAT – the "Company"), a clinical-stage biotechnology company and a leader in the development of Microbiome Ecosystem Therapies TM (MET) dedicated to enhancing survival for patients with cancer through immune modulation, announced additional findings following full data readout for the exploratory single-arm, open-label Phase 1b clinical trial named IASO ( NCT05889572 ) evaluating MaaT033 in Amyotrophic Lateral Sclerosis (ALS). In November 2024 , the Company announced that the trial had met its primary endpoint assessing the safety and tolerability of MaaT033 with multiple doses, following the independent Data Safety and Monitoring Board (DSMB) conclusion. As a reminder, the exploratory Phase 1b trial enrolled a total of 15 participants across two centers in France Hôpital de la Pitié-Salpêtrière – AP-HP and the University Hospital of Lille. An external Scientific Advisory Committee took place at the end of March 2025 to review the full data. Below are the key takeaways from the Committee’s review: In addition, the Scientific Advisory Committee provided insights regarding the best population to target in a Phase 2 trial. "These encouraging findings from the IASO Phase 1b trial confirm the favorable safety and tolerability profile of MaaT033 in ALS patients. They also highlight the therapeutic potential of microbiome modulation beyond oncology and open new avenues for development in neurodegenerative diseases, as evidence continues to grow around the gut-brain connection," said Gianfranco Pittari, MD, PhD, Chief Medical Officer of MaaT Pharma. The study was conducted in close collaboration with the French patient association Tous en Selles contre la SLA (TECS) , highlighting the essential role of patients and their advocates in advancing science, and with the support of experts from the French academic networks FILSLAN and ACT4ALS-MND. "Recognizing the significant unmet medical need in ALS and with the will to support those affected, we applied our discovery platform to this new disease area, demonstrating its potential beyond our primary focus in oncology with encouraging Phase 1 data. In light of the Company’s strict financial discipline, and considering the recent successes achieved in oncology, we are actively seeking partners with a focus on ALS and the financial capacity to support new options to fight this disease," stated Hervé Affagard, CEO and co-founder of MaaT Pharma. –-- About MaaT033 MaaT033, a standardized, donor-derived, high-richness, high-diversity oral Microbiome Ecosystem Therapy TM containing anti-inflammatory Butycore TM species, is currently being developed as an adjunctive therapy to improve overall survival in patients receiving HSCT and other cellular therapies. MaaT033 is developed with the "pooling" technology, which allows pooling donations from multiple donors to create a standardized product with high microbial richness and diversity. It aims to ensure optimal microbiota function and to address a larger patient population in a chronic setting. MaaT033 has been granted Orphan Drug Designation by the European Medicines Agency (EMA). About Amyotrophic Lateral Sclerosis Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig's disease in the US and Charcot’s disease in Europe, is a progressive neurodegenerative disorder affecting motor neurons in the brain and spinal cord. This leads to muscle weakness, loss of voluntary movement, and eventually, paralysis and on an average lead to death in 3 to 5 years. ALS could affect up to 60,000 patients in US and EU by 2040 and has currently no curative treatment and few symptomatic treatments.
