Pazopanib Paediatric Phase II Trial Children's Oncology Group (COG) in Solid Tumors
The purpose of this study is to find out what effects, good or bad, pazopanib (GW786034), National Service Center (NSC) # 737754, has on children, adolescents and young adults between 12 months and less than or equal to 18 years of age with relapsed or refractory rhabdomyosarcoma, non rhabdomyosarcomatous soft tissue sarcoma, Ewing sarcoma, relapsed or refractory osteosarcoma, neuroblastoma (measurable and/or evaluable), or hepatoblastoma. This is a two-stage open label phase II trial of pazopanib in children, adolescents and young adults with recurrent or refractory solid tumors. Eligible subjects will receive pazopanib daily as an oral tablet (450 mg/m^2/dose) or as a powder for suspension (225 mg/m^2/dose) in 28 day cycles. The maximum dose to be administered daily for tablets is 800 mg and for suspension 400 mg. Subjects will be closely monitored with clinical and laboratory observations for side effects. Response to treatment will be evaluated using appropriate imaging studies. In the absence of severe toxicity or progressive disease, subjects may continue receiving pazopanib.
Stanford is currently not accepting patients for this trial.
