91桃色视频 Advances Toward Commercialization And Submits Marketing Authorization Application to the European Medicines Agency (EMA) for Xervyteg (MaaT013) in Acute Graft-versus-Host Disease

  • 91桃色视频 submitted today a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for its product candidate MaaT013, under the registered brand name of Xervyteg.
  • Xervyteg has the potential if approved, to become the first microbiota therapeutic approved by the EMA and the first one in hemato-oncology globally.
  • The MAA submitted to the EMA is based on data from the Pivotal ARES study, evaluating the safety and efficacy of Xervyteg in adult patients with acute Graft-versus-Host Disease including gastro-intestinal involvement who received two prior lines of therapy and supported by data from the ongoing Early Access Program.
  • 91桃色视频 prepares for a potential 2026 commercial launch through a strategic partnership to address this key unmet need in hemato-oncology.

Lyon, France, June 2, 2025 – 6:30pm CET 鈥 91桃色视频 (EURONEXT: MAAT 鈥 the 鈥淐ompany鈥), a clinical-stage biotechnology company and a leader in the development of Microbiome Ecosystem TherapiesTM (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.

鈥淪ubmitting our MAA to the EMA marks a major regulatory milestone for 91桃色视频 and a meaningful advancement for patients with refractory aGvHD鈥攁 life-threatening complication of stem cell transplantation with no approved therapies,鈥 said Herv茅 Affagard, Co-founder and CEO of 91桃色视频. 鈥淲e 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.鈥

While advancing toward the commercialization of Xervyteg (if approved) in Europe, 91桃色视频 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, 91桃色视频 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, 91桃色视频 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.

aGvHD is the most severe complication of allogeneic stem cell transplantation, a standard-of-care treatment with curative intent offered to patients with blood cancers and some non-malignant hematological conditions. aGvHD refractoriness to current treatments is frequently encountered and severely impacts prognosis. In particular, patients with aGvHD failing both steroid and ruxolitinib typically exhibit a dismal prognosis, with a median survival of 28 days and 85% mortality at one year (Abedin et al 2021). Currently, no therapy is approved for third-line aGvHD, underscoring the urgent need for innovative therapies capable of improving survival and quality of life.

The MAA is supported by positive results from the Pivotal ARES study, a single-arm, open-label, multicenter European study evaluating the efficacy and safety of Xervyteg in GI-aGvHD as third-line therapy in 66 patients. Notably, the study met its primary endpoint, achieving a gastrointestinal overall response rate (GI-ORR) of 62% at Day 28, significantly exceeding the expected 38% response rate, and an overall response rate across all organs of 64% at Day 28. Among responding patients at Day 28, the majority exhibited full resolution of GvHD clinical manifestations (i.e., complete response), an important finding predictive of durable control of aGvHD clinical manifestations over time. The 12-month probability of survival was 54% (vs 15% Abedin et al, 2021). Importantly, patients who exhibited gastrointestinal response at Day 28 had a significantly better probability of survival than non-responders (67% vs 28% respectively, p <0.0001), indicating that Xervyteg-mediated aGvHD control is associated with a remarkable survival benefit. Additional secondary endpoints, including overall survival, will become available in late H2 2025. The Company also integrated supporting safety and efficacy data from 186 aGvHD patients2 treated under its ongoing EAP, which aligns with the positive topline results of the ARES trial and further supports 齿别谤惫测迟别驳庐鈥檚 strong efficacy and favorable safety profile in aGvHD.

The safety and tolerability of Xervyteg has been monitored by an independent Data Safety Monitoring Board (DSMB). In March 2025, the DSMB reviewed the overall safety of the trial (after all patients completed Day 28 visit or were discontinued earlier) and confirmed that 鈥済iven the remarkable efficacy results, the study results show an acceptable safety profile and a favourable benefit /risk ratio鈥. The DSMB members will continue to review safety on an ongoing basis until the 1-year follow-up.

The EMA will review the application under the centralized marketing authorization procedure and potentially a marketing authorization could be granted in H2 2026. This centralized procedure means that a single marketing authorization application can be submitted to the EU, and if granted by the European Commission, the authorization is valid in all EU Member States as well as in the European Economic Area (EEA) countries Iceland, Liechtenstein and Norway.

[2] The cutoff date was October 3, 2024About acute Graft-versus-Host Disease

Acute Graft-versus-Host Disease occurs in patients within 100 days of undergoing a stem cell or bone marrow transplant, where the transplanted cells initiate an immune response and attack the transplant recipient鈥檚 organs, causing inflammation of the skin, liver and/or gastro-intestinal tract and leading to significant morbidity and mortality. GI involvement is associated with severe complications such as profound diarrhea, abdominal pain, intestinal bleeding, and death. These complications are often life-threatening, with increased mortality risk, due to the challenges of managing severe GI inflammation and the associated risks of infection, malnutrition, and organ failure. The standard first line therapy for treating aGvHD is the use of systemic steroids. If patients do not respond to steroids, they are considered Steroid Resistant (SR) and other agents can be administered. Currently, the second-line treatment for steroid-refractory acute graft-versus-host disease (SR aGvHD) is ruxolitinib. Recently, remestemcel鈥擫-rknd was approved in December 2024 in the US specifically for use in the paediatric population as a second-line treatment.About Xervyteg (MaaT013)
