MaaT Pharma Advances Toward Commercialization And Submits Marketing Authorization Application to the European Medicines Agency (EMA) for Xervyteg (MaaT013) in Acute Graft-versus-Host Disease

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, today announced the submission of the Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for its lead drug candidate MaaT013, under the registered brand name of Xervyteg. If approved, the Marketing Authorization would establish Xervyteg as the first microbiota therapeutic approved by the EMA, and the first one globally for a hematology indication. Xervyteg would also be the first approved therapy for the treatment of acute Graft-versus-Host Disease including gastro-intestinal involvement (GI-aGvHD) following 2 prior lines of systemic therapy.

“Submitting our MAA to the EMA marks a major regulatory milestone for MaaT Pharma and a meaningful advancement for patients with refractory aGvHD—a life-threatening complication of stem cell transplantation with no approved therapies,” said Hervé Affagard, Co-founder and CEO of MaaT Pharma. “We are now closer to providing a much-needed treatment option and remain deeply committed to advancing immunomodulating microbiota technologies in hemato-oncology, where new solutions are urgently needed.”

While advancing toward the commercialization of Xervyteg (if approved) in Europe, MaaT Pharma is also actively exploring strategic partnerships to ensure broad access in timely fashion. The Company has active discussions with experienced partners who share its mission of delivering meaningful advancements to patients.

In parallel to the MAA submission, MaaT Pharma continues to provide access to Xervyteg in Europe and the U.S. through its Early Access Program (EAP)¹ for patients with aGvHD and other indications. In 2024, physician demand for Xervyteg under the EAP (n=107) increased by 75% compared to 2023, driven by growing adoption across Europe and in the U.S. In France where the EAP first started, MaaT Pharma has captured 25% of the addressable market on a yearly basis in 2024. Overall, this position reflects the increasing recognition of Xervyteg as a valuable treatment option for GI-aGvHD patients.
