Trial of Regulatory T-cells Plus Low-Dose Interleukin-2 for Steroid-Refractory Chronic Graft-versus-Host-Disease

• Status: Active, not recruiting
• Trial end date: 2021-12-01

Summary

This research study is a Phase I clinical trial, which tests the safety of an investigational combination of IL-2 plus donor anti-inflammatory Treg cells and also tries to define the appropriate dose of the investigational combination of IL-2 plus donor anti-inflammatory Treg cells to use for further studies. IL-2 is involved with cell signaling and regulation of white blood cells (WBCs). WBCs are part of the immune system. Treg cells are also part of the immune system; they are involved with anti-inflammatory responses. "Investigational" means that the combination of IL-2 and anti-inflammatory Treg cell infusion is being studied. It also means that the FDA (U.S. Food and Drug Administration) has not approved the combination of IL-2 and anti-inflammatory Treg cell infusion for use in people with cGVHD.

Chronic GVHD is a medical condition that may occur after you have received your bone marrow, stem cell or cord blood transplant from a donor. The donor's immune system may recognize your body (the host) as foreign and attempt to 'reject' it. This process is known as graft-versus-host disease.

Traditional standard therapy to treat cGVHD is prednisone (steroids). Participants on this trial have not responded to steroid therapy. The investigators are looking to assess the safety and optimal dose for the combination of IL-2 plus donor anti-inflammatory Treg cells, that may help control cGVHD by stopping the donor's immune system from 'rejecting' your body.
