This clinical trial is focused on studying a condition known as chronic graft-versus-host disease (cGVHD). This condition can occur after a bone marrow or stem cell transplant, where the donated cells attack the recipient’s body. The study will explore the effects of a treatment combining two medications: Axatilimab and Ruxolitinib. Axatilimab, also known by its code name INCA034176, is given as a solution for infusion, which means it is administered directly into the bloodstream. Ruxolitinib, also known as Jakavi, is taken in tablet form and works by selectively inhibiting certain enzymes involved in the immune response.
The purpose of this study is to evaluate the safety and effectiveness of the combination of Axatilimab and Ruxolitinib in people who have been newly diagnosed with cGVHD. Participants in the study will receive these medications over a period of up to 24 months. Some participants may receive a placebo, which is a substance with no active medication, to help compare the effects of the treatment. The study will monitor how well the treatment works and any side effects that may occur.
Throughout the study, participants will have regular check-ups to assess their response to the treatment and to ensure their safety. The study aims to provide valuable information on whether the combination of Axatilimab and Ruxolitinib can improve outcomes for individuals with cGVHD. This research could potentially lead to better treatment options for those affected by this challenging condition.
