A Multiple Ascending Dose Study of R1507 in Children and Adolescents With Advanced Solid Tumors.

This study has been completed.
Information provided by (Responsible Party):
Hoffmann-La Roche Identifier:
First received: November 16, 2007
Last updated: October 29, 2016
Last verified: October 2016
This 3 arm study will determine the dose of R1507 which will achieve a mean drug exposure in children and adolescents with advanced solid tumors equivalent to the exposure achieved in adults at the recommended dose of 9mg/kg/week. It will also determine the maximum tolerated dose (if appropriate) and the pharmacokinetic profile of R1507. Groups of patients will be sequentially enrolled in one of up to 3 dose levels (3,9mg/kg or a PK-derived dose, not to exceed 16 mg/kg) of R1507 administered weekly by intravenous infusion.An expanded cohort of patients will be enrolled at the optimal dose/MTD. The anticipated time on study treatment is until disease progression or dose limiting toxicity, and the target sample size is <100 individuals.
