Tacrolimus and Sirolimus as Prophylaxis After Allogenic Non-myeloablative Peripheral Blood Stem Cell Transplantation
The purpose of this study is to extend the use of Tacrolimus and Sirolimus to determine how effective it is in preventing graft versus host disease (GVHD)in patients that have received non-myeloablative peripheral blood stem cell transplantation.

|Official Title:||Tacrolimus and Sirolimus as Graft Versus Host Disease Prophylaxis After Allogeneic Non-myeloablative Peripheral Blood Stem Cell Transplantation|
- Incidence of Grade II-IV Acute GVHD (aGVHD) Developing by Day 100 Following Non-myeloablative PBSC Transplantation Using Tacrolimus and Sirolimus. [ Time Frame: 100 days ] [ Designated as safety issue: Yes ]All participants received tacrolimus and sirolimus in this one arm study. There were no participants considered unevaluable for this measure (deceased prior to day 100). The total number of people who developed grade II-IV aGVHD before day 100 are reported here.
- Percentage of Participants With ≥90 Percent Donor-derived Hematopoeisis Around 100 Days Post Transplantation [ Time Frame: 100 days ] [ Designated as safety issue: No ]The percentage of participants with ≥90 percent donor-derived hematopoeisis was assessed around day +100 using peripheral blood chimerism.
- Disease Response. [ Time Frame: 2 years ] [ Designated as safety issue: No ]Disease response was assessed as 2 year progression-free survival. The median follow-up time was 1.84 years. The percentage of participants with who reached this timepoint with no disease progression are reported.

- After the screening procedures confirm that the patient is eligible to participate in the research study, they will be admitted to the hospital to receive chemotherapy and stem cell transplantation (SCT). The duration of the hospitalization for the procedure is approximately 8 days.
- Patients will receive fludarabine once daily over 30 minutes intravenously for 4 days and busulfex once daily over 3 hours intravenously each day for the same 4 days.
- Just prior to the transplant and following the transplant the patient will receive sirolimus and tacrolimus to help prevent Graft versus Host Disease (GvHD). Both medications are taken orally.
- Patients will also take medications to help prevent possible infections (e.g. acyclovir). Filgrastim, a white blood cell growth factor, will be given daily in an injection under the skin, starting the day after the stem cell transplant and until the patients blood counts have recovered.
- After the stem cell infusion, the patient will be examined and have blood tests weekly for 1 month. At about the 1-month visit, a bone marrow biopsy and/or blood tests will be performed to determine the percentage of donor's cells in the blood or bone marrow. These tests will be repeated at 3-4 months after transplant.
- At 3-4 months after the transplant, patients will also have tests to reassess the response of your disease to transplant. This may involve a bone marrow biopsy, blood tests, and/or radiology studies depending upon the type of cancer.
- Follow-up will continue for the remainder of the patients life.
