Filter by:This study proposes to treat patients with the combination of erlotinib and temozolomide. Patients with relapsed, recurrent, refractory, or high risk malignancies whose tumors possess a non-synonymous mutation in EGFR, ERBB2, or JAK2V617F (JAK2) will be eligible for the study. Very few phase 2 clinical trials have been performed in pediatrics using targeted agents in combination with conventional chemotherapy agents. Furthermore, since some combinations such as the combination of this study (erlotinib and temozolomide) have shown additive/synergistic effects in preclinical studies, therapy selecting for those patients who possess mutations targeted by the TKI of the study, may unveil activity that has not been previously observed. Thus, the investigators hope to determine whether the addition of additive/synergistic chemotherapy will increase efficacy of target agent and/or increase tumor susceptibility to targeted agent resulting in increased anti-tumor activity.
Background: - The anti-cancer drug RO4929097 is being tested for its ability to block blood vessel growth to tumors and slow or stop the growth of cancer cells. However, it has been used in only a small number of adults and has not yet been tested in children. Researchers are interested in determining whether RO4929097 is a safe and effective treatment for tumors or leukemia that has not responded to standard treatment. Objectives: - To determine the safety and effectiveness of RO4929097 as a treatment for children and adolescents who have been diagnosed with certain kinds of cancer that have not responded to standard treatment. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid, nervous system, or blood-based cancers that have not responded to standard treatment. Design: - Participants will be screened with a medical history, physical examination, blood and urine tests, and imaging studies. Some participants may also have a bone marrow biopsy to evaluate the state of their disease. - Participants will be separated into three groups: One group will receive RO4929097 alone, and the other two will receive RO4929097 in combination with the immune-suppressing drug dexamethasone. - RO4929097 will be given as tablets on one of two schedules: days 1 to 3 of every week (Schedule A) or days 1 to 5 of every week (Schedule B). The dosing schedule will be determined randomly. Every 4-week treatment period is one cycle, and participants may receive RO4929097 for up to 24 cycles. - Participants will have frequent blood and urine tests and imaging studies to evaluate the progress of treatment, and will be asked to keep a diary to monitor any side effects.
Background: - Pazopanib, a drug that inhibits the growth of new blood vessels in tumors, was recently approved by the Food and Drug Administration to treat advanced kidney cancer in adults. Pazopanib has been used in only a small number of adults, and more research is needed on whether it is safe and effective to use in children. Researchers are interested in determining safe and effective treatment doses of pazopanib in children, and in other studies will examine which form of pazopanib treatment (tablet or liquid) is most effective and well tolerated. Objectives: - To determine a safe and effective dose of pazopanib to treat solid tumors in children. - To study the effects of pazopanib on blood cells, blood flow, and human development. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid tumors that have not responded to treatment. Design: - Eligible participants will be screened with a physical examination, blood and tumor samples, and imaging studies. - Participants will receive pazopanib tablets for 28-day cycles of treatment. Pazopanib should be taken on an empty stomach, at least 1hour before or 2 hours after a meal. Participants may receive pazopanib for up to 24 cycles unless the tumor does not respond or participants develop serious side effects. - Blood samples will be taken on days 1, 15, 22, and 27 of the first cycle of pazopanib, with additional samples taken every 8 weeks during subsequent cycles. - An optional part of the study will collect additional blood samples at regular intervals for 24 hours after the first dose of pazopanib and at regular intervals after another dose during the second or third week of the first treatment cycle.
The Late Effects Study is being conducted in order to answer scientific questions and to serve as a resource for Wilms tumor patients and their families. Patients must have been enrolled on the NWTS-5 protocol in order to be eligible for this study.
