The HERACLES results include data from 24 patients with grade III-IV, steroid-resistant, gastrointestinal (GI)-predominant, acute Graft-versus-Host-Disease (aGvHD) that were treated with MaaT013 as second line therapy. The EAP results include data from 52 patients treated with MaaT013, with steroid-resistant or steroid-dependent aGvHD with GI involvement, who had previously failed 1 to 6 lines (median: 3) lines of systemic therapy; MaaT Pharma provided the product to hospitals under a compassionate access program in France ("accès compassionnel"- EAP). MaaT013 is a high-richness, high-diversity Microbiome Ecosystem Therapy (MET) derived from pooled donations from strictly vetted healthy individuals and is presented as an enema.

The data will be presented by Prof. Mohamad Mohty, professor and head of the Hematology and Cellular Therapy Department at the Saint-Antoine Hospital and Sorbonne University.
