MaaT Pharma (EURONEXT: MAAT – the “Company”), a French clinical-stage biotech and a pioneer in the development of Microbiome Ecosystem Therapies^TM (MET) dedicated to improving survival outcomes for patients with cancer, today reported its cash position as of June 30, 2022, and its revenues for the second quarter of 2022.

“The second quarter of 2022 saw further progress in our pipeline and the achievement of a crucial milestone for MaaT Pharma. The announcement of data showing a satisfactory safety profile and robust engraftment for MaaT033, our second drug candidate, opens an attractive market opportunity to expand the development to a wider patient population as we focus on preventing complications in patients receiving allo-HSCT² and in haematological malignancies overall,” said Hervé Affagard, CEO and co-founder of MaaT Pharma.

Second quarter operational and clinical highlights

Clinical development

• In June 2022, the Company confirmed positive results from its Phase 1b study evaluating MaaT033, the Company’s second drug candidate, in blood cancer patients; the clinical trial was completed early due to promising interim results.
• MaaT Pharma also indicated that preparations are on track for the upcoming Phase 2/3 trial to evaluate MaaT033’s efficacy in improving overall survival and preventing complications in patients with blood cancers receiving allogeneic hematopoietic stem cell transplantation; based on current plans, this study is expected to start in Q4 2022.
• In Europe, MaaT013, the Company’s leading drug candidate, is currently being evaluated in two clinical trials launched in Q1 2022, which are moving forward according to the Company’s expected timelines:
  • Phase 3 open label, single arm trial for drug candidate MaaT013 in the treatment of acute Graft-versus-Host Disease: in addition to France, Germany, and Spain where the trial is ongoing, the Company has received regulatory approvals to start the clinical trial in Austria and Belgium. An interim review of preliminary data is expected in the first half of 2023.
  • Phase 2a trial, sponsored by AP-HP³, evaluating MaaT013 in combination with immune checkpoint inhibitors for patients with melanoma, is ongoing.
  • In the US, interactions with the U.S. Food and Drug Administration (FDA) are ongoing regarding MaaT013, for which US development is currently on clinical hold.
