8 Clinical Trials for Various Conditions
While neurocognitive impairments in attention, memory and executive functioning are commonly reported sequelae of childhood leukemia and brain tumors, studies have only recently begun to examine the treatment of attention deficits in this population. Numerous studies have examined the effectiveness of methylphenidate in the treatment of children with attention deficit hyperactivity disorder (ADHD). However, the effectiveness of this medication for improving attention and behavioral functioning in children with medical illnesses or brain injury are less clear. Patients will be randomized to receive one week of Metadate CD (a controlled release form of methylphenidate, similar to Ritalin) and one week of placebo in a double-blind fashion.
The purpose of this clinical research study is to provide dasatinib treatment to patients with advanced chronic myelogenous leukemia (CML) or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) who no longer can tolerate treatment with imatinib. The safety of the treatment will also be studied.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of 506U78 in treating patients who have recurrent or refractory acute lymphocytic leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and combining drugs in different ways may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of chemotherapy in treating children who have very high risk acute lymphocytic leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and giving the drugs in different combinations may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of standard combination chemotherapy treatment with more intensive combination chemotherapy in treating children with acute lymphocytic leukemia.
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy with or without bone marrow transplantation in treating patients who have acute lymphocytic leukemia.
RATIONALE: A peripheral stem cell transplant or an umbilical cord blood transplant from a donor may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells can make an immune response against the body's normal cells. Methotrexate, cyclosporine, tacrolimus, or methylprednisolone may stop this from happening. PURPOSE: This clinical trial is studying how well a donor stem cell transplant or donor white blood cell infusions work in treating patients with hematologic cancer.
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.
