Brief summary:
The purpose of this research study is to test the safety and effectiveness of VELCADE® in the treatment of acute graft-versus-host disease (GVHD) that has not responded to steroids or has worsened when the steroid dose was decreased. VELCADE® is a drug that inhibits certain immune reactions that happen when lymphocytes encounter foreign substances. We are doing this research to determine if VELCADE® may be useful in treating GVHD.

Detailed description:
Graft-versus-host disease (GVHD) is a serious complication after bone marrow transplantation from another donor. GVHD is caused by certain cells called lymphocytes. Normally these cells make immune reactions that help protect the body from foreign substances that cause infection. Here, these cells attack the normal tissues of the body as if they were foreign substances. This interferes with the normal function of vital organs and results in their damage. In GVHD these cells attack the skin, liver and bowel. GVHD also increases the chances of infection.

VELCADE® is a drug that inhibits certain immune reactions that happen when lymphocytes encounter foreign substances. We are doing this research to determine if VELCADE® may be useful in treating GVHD.

VELCADE® is approved by the Food and Drug Administration (FDA) for the treatment of multiple myeloma in patients who have received at least two prior therapies and have demonstrated disease progression on their last therapy. Its effectiveness is also being tested in other cancers. The dose of the drug being used in this research study is the same as what is used for the treatment of multiple myeloma. It has not been approved by the FDA for use in GVHD. Therefore, using VELCADE® for GVHD is experimental in this research study.

Arms:
arm 1: To determine if bortezomib (VELCADE®) will successfully inhibit T-cell responses in clinically acute graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT).

Interventions: intervention 1: Bortezomib
Intervention descriptions: intervention 1: Bortezomib at 1.3 mg/m2/dose given twice weekly for two weeks followed by a 10-day rest period. If patients have a complete response, they will receive additional cycles of bortezomib.
