Primary outcomePrimary: Lag Time (Tlag) of Ridaforolimus: Day 1 — 2.00 Hours
Summary
Part 1 of the study will assess the pharmacokinetics, safety, and tolerability of ridaforolimus (MK-8669) 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 treatment in a weekly regimen of daily oral doses of ridaforolimus 40 mg for five consecutive days followed by two days off-treatment.
