MaaT Pharma presented new in vitro data characterizing the metabolites produced by MaaT034 and their impact on immune modulation at the American Association for Cancer Research (AACR) Annual Meeting 2024 in San Diego, California. MaaT034, the first product from MaaT Pharma?s MET-C platform is a ground-breaking full ecosystem synthetic microbiota product, developed in combination with immune checkpoint inhibitors to improve treatment efficacy in large market solid tumor indications. The MET-C platform enables MaaT Pharma to produce microbiome therapies at a large-scale to meet the needs of larger market indications.

The first-in-human study is expected to be initiated in 2025. The data published represents significant advancements in understanding the mechanism of action (MoA) of co-cultured microbiome therapies developed by MaaT Pharma, marking a major step towards clinical evaluation. The results demonstrate that MaaT034 produced key metabolites, recognized as promoting gut barrier restoration and modulating immune responses, such as Short-Chain Fatty Acids (SCFA), secondary bile acids, and tryptophan derivatives.

These findings support the role of MaaT034 in gut barrier repair and in T cell reactivation either in combination with Nivolumab (anti-PD1) or with Atezolizumab (anti-PD-L1). By enhancing gut barrier repair and modulating immune responses, MaaT034 is expected to complement the action of these immunotherapeutic agents, potentially improving their efficacy in treating solid tumors cancer.
