3 Clinical Trials for Various Conditions
This is a two-part, open-label, Phase I/II study in subjects with relapsed or refractory TdT-positive leukemia for which no standard therapies are expected to result in durable remission.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of chemotherapy consisting of cordycepin plus pentostatin in treating patients with refractory acute lymphocytic or chronic myelogenous leukemia.
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells are rejected by the body's normal tissues. Transplanting donated cells that have been treated with psoralen may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of chemotherapy, radiation therapy, and psoralen-treated donor cells in treating patients who are undergoing peripheral stem cell transplantation for hematologic cancer.
