Active Accrual, Protocols Recruiting New Patients

Title:
Phase I Trial and Pharmacokinetic Study of BMS-247550 (NSC 710428, Ixabepilone), an Epothilone B Analog, in Pediatric Patients with Refractory Solid Tumors and Leukemias
Number:
02-C-0031
Summary:
This study will determine the highest dose of the experimental anticancer drug BMS-247550 that can be given safely to children. It will examine how the body handles the drug, its side effects, and its effect on the tumor. BMS-247550 belongs to a class of drugs called epothilones. These drugs are similar to another class called taxanes, which includes paclitaxel (Taxol® (Registered Trademark)) and docetaxel (Taxotere® (Registered Trademark)). The epithiones are able to kill cancer cells that are resistant to Taxol® (Registered Trademark).

Children 2 to 18 years of age and older with solid tumor cancers that do not respond to standard therapy may be eligible for this study. Cancers may include rhabdomyosarcoma and other soft tissue sarcomas, Ewing's sarcoma tumors, osteosarcoma, neuroblastoma, Wilms' tumor, liver tumors, germ cell tumors, brain tumors, and others. Candidates will be screened with a medical history and physical and neurological examinations; height, weight, and body surface area measurements; blood and urine tests; and x-ray studies to determine the extent of disease.

Participants will receive BMS-247550 intravenously (through a vein) over a 60-minute period for 5 consecutive days in 21- to 28-day cycles (i.e., 5 days of drug treatment followed by 15 to 22 days without drug, depending on the amount of time needed to recover from the drug side effects). The drug dose will be increased in successive small groups of patients, if the side effects at the previous dose are acceptable, until the optimum dose is achieved. Patients may continue treatment indefinitely unless their cancer worsens or they develop side effects that persist for more than 2 weeks.

Patients will be followed with a physical examination every week and routine blood tests twice a week. They will have computed tomography (CT) or magnetic resonance imaging (MRI) scans after the first treatment cycle and then after every other treatment cycle to evaluate the size of their tumor. In addition, they will have the following blood studies:

-Pharmacology studies: During the first treatment cycle, blood samples will be drawn frequently to examine how the body absorbs and uses the drug. For this study, 12 blood samples of 1.5 teaspoons each will be drawn after the first dose of BMS-247550; two samples each will be drawn on treatment days 2 through 5; and, if possible, one sample will be drawn at 24 and 48 hours after the fifth dose of drug. To avoid multiple needle sticks for the first day's samples, the blood will be collected through the child's permanent venous catheter (Hickman line or port-a-cath) or through an IV heparin lock (a small plastic catheter inserted into the vein).

-Drug effects on normal cells: To determine the effect of the drug on normal cells circulating in the blood, samples will be collected before, and 1 hour, 6 hours, and 24 hours after the first dose of drug in the first treatment cycle.

-Measurement of nerve growth factor: Blood will be collected to measure the effect of BMS-247550 on a substance called nerve growth factor to determine which patients may be at risk for developing nervous system side effects. Blood samples will be collected before the first dose of treatment, before the second and third treatment cycles, at the end of the study, and in the event that the child develops signs of nerve damage, such as pain, tingling, or changes in sensation in the hands and feet.
