Study of Dalotuzumab Alone and With Ridaforolimus in Pediatric Participants With Advanced Solid Tumors (MK-8669-062 AM1)

For Part 1: dalotuzumab, intravenously (IV) over 60 minutes every three weeks, dose based on participant body surface area (BSA), starting dose of 900 mg/m\^2, and escalated for successive cohorts of participants until MTD is found

For Part 2: dalotuzumab IV over 60 minutes every three weeks, dose based on participant BSA, starting at the lowest tolerated dose that met PK target levels in Part 1. For Part 3: dalotuzumab IV over 60 minutes every three weeks, dose based on participant BSA, at the dose level identified for combination therapy in Part 2

For Part 2: ridaforolimus 10 mg enteric coated tablets, orally, on 5 consecutive days each week, dose based on participant BSA, at 1 dose level lower than the MTD or highest dose level used in the companion study MK-8669-056. For Part 3:ridaforolimus 10 mg enteric coated tablets, orally, on 5 consecutive days each week, dose based on participant BSA, at the dose level identified for combination therapy in Part 2
