A Clinical Trial to Assess the Efficacy and Safety of MK-0653C in Japanese Participants With Hypercholesterolemia (MK-0653C-383)

Phase 3

Completed

• Conditions: Hypercholesterolemia
• Interventions: Drug: Ezetimibe 10 mg; Drug: Atorvastatin 10 mg; Drug: Placebo for Ezetimibe 10 mg tablet; Behavioral: Diet control/Daily Exercise; Drug: Placebo for Atorvastatin 10 mg capsule

• Registration Number: NCT02550288
• Lead Sponsor: Organon and Co

Brief Summary

This study will evaluate the efficacy and safety of MK-0653C (Ezetimibe \[EZ\] 10 mg/Atorvastatin \[Atora\] 10mg or 20 mg) compared to EZ 10 mg, Atora 10 mg, or Atora 20 mg alone when administered to Japanese participants with hypercholesterolemia. The primary hypothesis is that MK-0653C (EZ 10 mg/Atorva 10 mg) is superior to EZ 10 mg and is superior to Atorva 10 mg and that MK-0653C (EZ 10 mg/Atorva 20 mg) is superior to EZ 10 mg and is superior to Atorva 20 mg in percent change from baseline in low-density lipoprotein cholesterol (LDL-C) after 12 weeks of treatment.
