MaaT Pharma Announces Second Positive DSMB Safety Assessment of Ph II Study in Acute GvHD

MaaT Pharma announced on 4/9/19 that the independent Data and Safety Monitoring Board (DSMB) recommended the continuation, without amendment, of the ongoing Phase II HERACLES study (NCT03359980). The HERACLES trial inverstigates the use of lead biotherapeutic MaaT013 in steroid-resistant, gastrointestinal-predominant, acute Graft-versus-Host-Disease (SR GI aGvHD) after allogeneic Hematopoietic Stem-Cell Transplantation (allo-HSCT). The second review assessed the safety of MaaT013 after 10 patients treated, reinforcing the absence of safety issues during the trial as confirmed after the first review. Enrollment of patients in the trial continues as planned with additional sites recently opened in Germany and Italy. As of today a total of 13 patients have been treated in the protocol.

“The high mortality rate of up to 80% after 6 months in gastrointestinal-predominant aGvHD poses a significant unmet medical need and we believe that MaaT013 will improve these patients’ outcomes through a differentiated approach of restoring their immune homeostasis,”
"The relevance of the microbiome in hemato-oncological diseases is increasingly recognized by the medical community and our mission is to develop the first, safe microbiome-based product to help patients with no other options. We look forward to communicating the top-line data of this trial later this year.”
