Allogeneic Stem Cell Transplant for CLL

Stopped early · Phase 1/Phase 2

Conditions studied: Allogeneic Hematopoietic Stem Cell Transplantation Recipient, Chronic Lymphocytic Leukemia, Prolymphocytic Leukemia, Richter Syndrome

In brief

This phase I/II trial studies the best dose and side effects of gemcitabine and how well it works with clofarabine and busulfan and donor stem cell transplant in treating participants with chronic lymphocytic leukemia. Drugs used in chemotherapy, such as gemcitabine, clofarabine, and busulfan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.

Men and women of reproductive potential must agree to follow accepted birth control methods for the duration of the study. Female subject is either post-menopausal or surgically sterilized or willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study. Male subject agrees to use an acceptable method for contraception for the duration of the study

You may not qualify if…

Patient with active central nervous system (CNS) disease
Pregnant (positive beta human chorionic gonadotropin [HCG] test in a woman with child bearing potential defined as not post-menopausal for 12 months or no previous surgical sterilization) or currently breast-feeding. Pregnancy testing is not required for post-menopausal or surgically sterilized women
Known infection with human immunodeficiency virus (HIV), human T-lymphotropic virus (HTLV)-I, hepatitis B, or hepatitis C
Active uncontrolled bacterial, viral or fungal infections
Patient has received other investigational drugs within 1 week before enrollment
