Xenikos partners up for testing efficacy T-Guard

News / 27-02-2020

Nijmegen, the Netherlands – Xenikos B.V. announced today that they have partnered up with the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) to conduct a U.S.-based Phase 3 registration trial to test the efficacy of T-Guard in treating steroid-refractory acute graft-versus-host disease (SR-aGVHD) in patients following an allogeneic stem cell transplant. Funded by the National Heart, Lung, and Blood Institute and the National Cancer Institute, the BMT CTN includes leading transplant centers in the United States (U.S.) and will provide a total of USD 1.37 million in funding for the T-Guard trial.


Xenikos develops innovative new immunotherapies based on conjugated antibodies. This novel therapeutic approach helps reset the immune system in patients who have a severe immune disease or developed post-transplantation rejection. Xenikos’ flagship product, T-Guard®, is designed to treat steroid-resistant acute graft-versus-host disease (SR-aGVHD), a life-threatening condition common in patients following a hematopoietic stem cell transplantation.


Dr. Ypke van Oosterhout, CEO of Xenikos, is confident that the partnership with BMT CTN will help bring T-Guard to transplant patients as quickly as possible: “At Xenikos, we see BMT CTN’s access to major transplant centers in the U.S., as well as their established track record for successfully recruiting patients with acute GVHD, and vast knowledge and expertise in this field, as aiding in the development of innovative new immunotherapies for improving patient outcomes”.


“Our network often conducts large, multi-institutional clinical trials in order to test new treatments designed to improve outcomes associated with hematopoietic stem cell transplantation or HSCT,” said Dr. Mehdi Hamadani of the BMT CTN. “Acute GVHD is a life-threatening complication of HSCT and better treatments are needed for our patients. The preliminary data obtained with T-Guard is quite promising, and we believe that the Phase 3 trial is the next logical step.”


The U.S.-based Phase 3 trial will be a multi-center study involving patients who have received an allogeneic stem cell transplant for a myeloid or lymphoid malignancy and subsequently developed SR-aGVHD. Importantly, the Phase 3 trial design is based on input received from the U.S. Food and Drug Administration at the End-of-Phase 2 meeting. Xenikos plans to file an Investigational New Drug application in 2019.
