黑料社 Announces Update on U.S. FDA Investigational New Drug Application for MaaT013 in Patients with Acute Graft-versus-Host Disease

Lyon, France, August 10th, 2022, 6:00 pm CET 鈥� 黑料社 (EURONEXT: MAAT 鈥� the 鈥淐ompany鈥�), a French clinical-stage biotech and a pioneer in the development of Microbiome Ecosystem TherapiesTM (MET) dedicated to improving survival outcomes for patients with cancer, today announced that it received a communication from the U.S. Food and Drug Administration (鈥淔DA鈥� or 鈥渢he Agency鈥�) related to the Company鈥檚 Investigational New Drug (IND) application filed in June 2021 to initiate in the U.S. an open-label, single-arm Phase 3 clinical trial of the Company鈥檚 drug candidate, MaaT013, in patients with steroid-resistant acute Graft-versus-Host Disease (aGvHD). Following questions raised by the FDA in August 2021 on this application in a clinical hold letter, the Company had previously submitted a request for a Type A meeting, as well as detailed responses to the Agency鈥檚 questions.A response letter was received in the evening on August 8th, 2022, Central European Time (CET). It indicates that the Agency maintains the clinical hold on MaaT013 in the U.S. and details the FDA鈥檚 position on the clinical trial. The Agency acknowledged that it received satisfactory answers from the Company on multiple clinical and manufacturing-related questions that the Agency had initially raised. However, the Agency requires additional information, notably regarding the safety and efficacy of the Company鈥檚 鈥減ooling鈥� approach (i.e. mixing donations from multiple donors to achieve higher richness, diversity and better standardization of the product). The Company is also evaluating additional recommendations made by the Agency regarding the trial design.

鈥淲e value the FDA鈥檚 continued engagement as we seek to extend the Phase 3 clinical trial of MaaT013 to the U.S. and we intend to work with the Agency to resolve the issues raised in the communication, while implementing a defined strategic plan to continue to deliver on our key milestones,鈥� said Herv茅 Affagard, CEO and co-founder of 黑料社. 鈥�To date, data gathered from more than 120 patients with aGvHD who received MaaT013 in Europe as part of our early access program in France and our completed Phase 2 trial in Europe, indicated a positive safety and efficacy profile for MaaT013. We remain focused on bringing innovative and safe microbiome therapies to patients with refractory aGvHD.鈥�

黑料社 is now in the process of preparing the next steps in the interaction with the FDA, potentially including a Type A meeting dedicated to discussing the remaining questions. In parallel and in line with its goal to reach patients globally, the Company will continue the development of MaaT013 in Europe and expand European recruitment for its ongoing Phase 3 trial evaluating MaaT013 in 75 patients. There are currently 19 active clinical sites in France, Germany, and Spain and the Company has submitted clinical trial applications in three additional European countries. The overall expected timelines for the Phase 3 trial and, if approved, commercialization of MaaT013 in Europe remain unchanged.

In parallel, the Company continues to prepare for the initiation of a Phase 2/3 trial in Europe to evaluate its second native (donor-derived) asset, MaaT033, in patients with blood cancers receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT). This clinical study is expected to start in Q4 2022.

The Company also continues to prepare a first-in-human trial of its first co-fermented MaaT03X candidate in both Europe and the U.S. This new class of drug candidates aims to improve the anti-cancer efficacy of immune checkpoint inhibitors in patients with a yet undisclosed solid tumor having a high unmet need.
