A Study of Ridaforolimus in Pediatric Participants With Advanced Solid Tumors (MK-8669-056)

Summary

The main objectives of this trial are to determine the recommended dose of ridaforolimus for pediatric participants with advanced solid tumors by measuring the number of participants experiencing dose-limiting toxicities (DLTs) while on different doses of ridaforolimus, and to characterize the pharmacokinetics of ridaforolimus in these participants. The primary hypotheses of this study are that 1) the DLTs observed will be dose-dependent and allow for definition of a maximum tolerated dose (MTD) and 2) at a safe and well tolerated dose, ridaforolimus geometric mean (GM) Day-5 blood area under the concentration-time curve at 24 hours (AUC0-24) exceeds 75% (or 1304-ng\*hr/mL) of the estimated GM Day-5, 40-mg AUC0-24 in adults. Study-related visits concluded in August 2013. Participants who did not have disease progression, adequately tolerated therapy, and continued to meet eligibility criteria for 6 months after the enrollment period had been completed could continue treatment in an extension phase until they met discontinuation criteria or voluntarily withdrew.
