- Patients may be enrolled who relapse after autologous stem cell transplant if they are at least three months after transplant, and after allogeneic transplant if they are at least six months post transplant; to be eligible after either type of transplant, patients must have achieved platelet counts greater than 100,000/mcL, and white blood cell (WBC) greater than 1,000/mcL at some point after their transplant, and 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
