Part 1 of the study will assess the pharmacokinetics, safety, and tolerability of ridaforolimus after administration of single and multiple 40 mg doses in Chinese participants with advanced cancer. Part 2 of the study is optional; participants can continue to receive the study drug in a weekly regimen of daily oral doses of ridaforolimus 40 mg for 5 consecutive days followed by 2 days off-drug.

- AUC [0-24 Hours] of Ridaforolimus [ Time Frame: Cycle 1 Day 1 and Day 19 ] [ Designated as safety issue: No ]
- Maximum Concentration (Cmax) of Ridaforolimus [ Time Frame: Cycle 1 Day 1 and Day 19 ] [ Designated as safety issue: No ]
- Concentration at 24 Hours (C[24 hr]) of Ridaforolimus [ Time Frame: Cycle 1 Day 1 and Day 19 ] [ Designated as safety issue: No ]
- Time to Maximum Concentration (Tmax) of Ridaforolimus [ Time Frame: Cycle 1 Day 1 and Day 19 ] [ Designated as safety issue: No ]
- Apparent Terminal Half-life (t1/2) of Ridaforolimus [ Time Frame: Cycle 1 Day 1 and Day 19 ] [ Designated as safety issue: No ]
