Acute Graft Versus Host Disease in Intestine

This is a pilot, prospective, non-profit, multicenter, uncontrolled, open-label study to evaluate the safety and feasibility of FMT in patients aged between 3 months and 25 years suffering from acute intestinal GVHD resistant to conventional steroid therapy. Eligible patients will receive 1-3 FMT via naso-jejunal tube or endoscopy.

MaaT013 is still in clinical development phase and is not approved yet for marketing in any region. During the development program, MaaT Pharma has undertaken initial development with closely related product candidates, leading to the Phase II HERACLES study in which MaaT013 preliminary safety and efficacy were assessed in the context of steroid-resistant, gastrointestinal aGraft versus Host Disease (SR-GI-aGvHD). In addition, a pivotal Phase III study (ARES trial) is planned. In the absence of medical options in patients with gastrointestinal acute GvHD refractory to multiple lines of treatment, this early access program has been implemented.
