- Patients who relapse after autologous stem cell transplant may be enrolled if they are at least three months after transplant, and after allogeneic transplant if they are at least one year posttransplant; patients should have no active related infections (i.e., fungal or viral); in the case of allogeneic transplant relapse, there should be no active acute graft versus host disease (GvHD) of any grade, and no chronic graft versus host disease other than mild skin, oral, or ocular GvHD not requiring systemic immunosuppression
