Standard of Care vs. Bortezomib in Graft-Versus Host Disease After Hematopoietic Stem Cell Transplant

Study Summary

This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA has not yet approved bortezomib to treat or prevent graft-versus-host disease. Bortezomib is approved by the FDA to treat other human malignancies. Bortezomib is a drug that has an anti-cancer effect that involves inhibiting cell growth and causing cell death. This drug has been used in other research studies, and information from thos other research studies suggests that bortezomib may help to lower the risk of GVHD after allogeneic stem cell transplantation in patients who have matched unrelated, unmatched related or unrelated donors in this research study. Allogeneic stem cell transplantation is a procedure in which selected blood cells taken from your sibling or unrelated donor are given to you. Lower doses of chemotherapy drugs are given before the donor cells are infused in a process known as reduced-intensity conditioning. Stem cell transplant destroys cancer in two ways: The conditioning regimen destroys cancer cells and teh immune cells from the donor can recognize cancer cells and kill them. A common problem after stem cell transplant is graft-versus-host disease (GVHD). The word "graft" refers to the donor blood cells that you will receive during your transplant. The word "host" refers to the person (in this case, you) receiving the cells. GVHD is a complication of transplantation where the donor graft attacks and damages some of your tissues. GVHD can cause skin rash, intestinal problems such as nausea, vomiting or diarrhea. GVHD may also damage your liver and cause hepatitis or jaundice.

Primary Outcome

The primary outcome of this study is the cumulative incidence of grade II-IV acute GVHD up to Day 180 after stem cell infusion. Acute GHVD is graded according to the modified Glucksberg criteria (adapted from Thomas et al., NEJM ,1975, pp. 895-90), which is based on criteria by which the provider classifies acute GVHD per its objective organ staging. Acute GVHD is assessed in weekly standard of care visits post stem cell infusion and is captured in the protocol EDC upon evaluation of clinical no
