Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Combination	NCT03249831 ↗	A Blood Stem Cell Transplant for Sickle Cell Disease	Recruiting	California Institute for Regenerative Medicine (CIRM)	Phase 1	2019-01-04	Blood stem cells can produce red blood cells (which carry oxygen), white blood cells of the immune system (which fight infections) and platelets (which help the blood clot). Patients with sickle cell disease produce abnormal red blood cells. A blood stem cell transplant from a donor is a treatment option for patients with severe sickle cell disease. The donor can be healthy or have the sickle cell trait. The blood stem cell transplant will be given to the patient as an intravenous infusion (IV). The donor blood stem cells will then make normal red blood cells - as well as other types of blood cells - in the patient. When blood cells from two people co-exist in the patient, this is called mixed chimerism. Most children are successfully treated with blood stem cells from a sibling (brother/sister) who completely shares their tissue type (full-matched donor). However, transplant is not an option for patients who (1) have serious medical problems, and/or (2) do not have a full-matched donor. Most patients will have a relative who shares half of their tissue type (e.g. parent, child, and brother/sister) and can be a donor (half-matched or haploidentical donor). Adult patients with severe sickle cell disease were successfully treated with a half-matched transplant in a clinical study. Researchers would like to make half-matched transplant an option for more patients by (1) improving transplant success and (2) reducing transplanted-related complications. This research transplant is being tested in this Pilot study for the first time. It is different from a standard transplant because: 1. Half-matched related donors will be used, and 2. A new combination of drugs (chemotherapy) that does not completely wipe out the bone marrow cells (non-myeloablative treatment) will be used to prepare the patient for transplant, and 3. Most of the donor CD4+ T cells (a type of immune cells) will be removed (depleted) before giving the blood stem cell transplant to the patient to improve transplant outcomes. It is hoped that the research transplant: 1. Will reverse sickle cell disease and improve patient quality of life, 2. Will reduce side effects and help the patient recover faster from the transplant, 3. Help the patient keep the transplant longer and 4. Reduce serious transplant-related complications.

NCT00038025 ↗	A Study Of Deoxycoformycin(DCF)/Pentostatin In Lymphoid Malignancies	Completed	M.D. Anderson Cancer Center	Phase 2	1994-09-06	The purpose of this study is to determine the side effects and antitumor response of patients with lymphoid malignancies to Deoxycoformycin (DCF)/Pentostatin.
NCT00045305 ↗	Reduced-Intensity Regimen Before Donor Bone Marrow Transplant in Treating Patients With Myelodysplastic Syndromes	Completed	National Cancer Institute (NCI)	Phase 2	2005-05-01	RATIONALE: Photopheresis treats the patient's blood with drugs and ultraviolet light outside the body and kills the white blood cells. Giving photopheresis, pentostatin, and radiation therapy before a donor bone marrow or stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving pentostatin before transplant and cyclosporine or mycophenolate mofetil after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving pentostatin together with photopheresis and total-body irradiation work before donor bone marrow transplant in treating patients with myelodysplastic syndromes.
