Participant Flow

Phase III First Patient In: 4/5/2006; Last Patient Last Visit 1/17/2008 72 centers worldwide (US, Canada, Austria, Costa Rica) Eligible patients include those on a stable dose of atorvastatin 20 mg; or patients with adjusted LDL-C pre-screen ranges who were treated with other lipid modifying therapy, or were statin and/or ezetimibe naïve.

Patients received and were blinded to atorvastatin 20 mg for a 4/5- week run-in period. Patients needed an LDL-C ≥ 100 mg/dL and ≤ 160 mg/dL at Visit 2 (week -1). Eligible patients were randomized at Visit 3 (Week 0) to either atorvastatin 40 mg or addition of ezetimibe 10 mg to their 20 mg dose of atorvastatin for a 6-week treatment period.
