Pharmacokinetics of Ridaforolimus (MK-8669) in Chinese Participants (MK-8669-059)

A Study to Assess the Pharmacokinetics of Ridaforolimus in Chinese Patients

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.

• Female participants must be post-menopausal.
• Male participants must agree to use a medically-acceptable method of contraception/barrier protection during the study and for 30 days after the last dose of study treatment.
• Participants must be healthy enough to receive the study treatments (that is, meet certain laboratory value parameters).
• Life expectancy of >3 months.
