We aren't doctors. Always consult your mD about BMS-247550 to Treat Children with Solid Tumors conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. BMS-247550 to Treat Children with Solid Tumors Clinical research trials and BMS-247550 to Treat Children with Solid Tumors health trials occur in a lot of of places throughout the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectivity of new does drugs. The role of the studies / projects is to resolve certain human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector corporations to detect remedies for all varieties of circumstances, such as BMS-247550 to Treat Children with Solid Tumors. BMS-247550 to Treat Children with Solid Tumors Clinical Trials and other clinical trials allow volunteers to obtain health treatment choices before they are available to the general public. Most times the human subjects recieve professional assistance for free of charge, and every now and again they are paid for their time. Sometimes there is a cost for a BMS-247550 to Treat Children with Solid Tumors clinical trial. Human subjects frequently get the finest healthcare available for their BMS-247550 to Treat Children with Solid Tumors condition. Risks are a reality, however, and may include extra or frequent physician visits, medical dangers (possibly life-threatening), and/or the treatment being uneffective. Trials are federally governed with strict guidelines to protect clinical trials patients.

BMS-247550 to Treat Children with Solid Tumors
For Condition: Neoplasms,Optic Glioma,Neoplasm by Histologic Type,Brainstem Tumor
Status: Recruiting
Sponsor(s): National Cancer Institute (NCI) ,
Synopsis: 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 tumors. BMS-247550 belongs to a class of drugs called epothilones. These drugs are similar to another class called taxanes, which includes paclitaxel (Taxol) and docetaxel (Taxotere). The epothilones are able to kill cancer cells that are resistant to Taxol. 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 and third treatment cycles, 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.
Details: BMS-247550 is a semi-synthetic analog of the natural product epothilone B. The epothilones are a novel class of microtubule-stabilizing agents obtained from the fermentation of the cellulose degrading myxobacteria, Sorangium cellulosum. Nanomolar concentrations of BMS-247550 are cytotoxic against a broad range of tumors in in vitro and in vivo preclinical models, and BMS-247550 has demonstrated activity in tumor cell lines that are naturally insensitive to or have developed resistance to paclitaxel. In phase I trials for adults with solid tumors objective responses were observed in patients refractory to taxanes. The mechanism of action, expanded range of activity and potency in preclinical studies, and preliminary results from early clinical trials make BMS-247550 a potentially important new agent for timely evaluation in the pediatric population. A pediatric phase I trial of BMS-247550 will be performed in children with refractory solid tumors to define the MTD, toxicity profile, dose-limiting toxicities, pharmacokinetics and pharmacodynamics. BMS-247550 will be administered intravenously over 1 hour daily for 5 consecutive days every 21 days. Results of this pediatric phase I trial will be compared to those of an ongoing Medicine Branch, NCI, phase I trial with BMS-247550 for adult patients with solid tumors, which uses the same dosing schedule and study endpoints.

INFORMED CONSENT: All patients or their legal guardians (if the patient is less than 18 years old) must sign a document of informed consent (screening protocol) prior to performing studies to determine patient eligibility. After confirmation of patient eligibility all patients or their legal guardians must sign the protocol specific informed consent to document their understanding of the investigational nature and the risks of this study before any protocol related studies are performed (other than the studies which were performed to determine patient eligibility). DURABLE POWER OF ATTORNEY (DPA): Patients who have brain tumors and who are 18 years of age will be offered the opportunity to assign a DPA so that another person can make decisions about their medical care if they become incapacitated or cognitively impaired.
