To Evaluate Ezetimibe Plus Atorvastatin Versus Atorvastatin in Patients With High Cholesterol Not Controlled on Atorvastatin 20 mg. - Study Results

Study Type:	Interventional
Study Design:	Randomized, Double Blind (Subject, Investigator), Active Control, Parallel Assignment
Condition:	Hypercholesterolemia
Interventions:	Drug: Comparator: atorvastatin Drug: Comparator: Placebo Drug: Comparator: ezetimibe Drug: Comparator: Placebo.

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
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.

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
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.

Number of Participants Who Attained Target LDL-C <100 mg/dL at Week 6 [ 6 weeks ]

Measure Type	Secondary
Measure Title	Number of Participants Who Attained Target LDL-C <100 mg/dL at Week 6
Measure Description	No text entered.
Time Frame	6 weeks
Safety Issue	No

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Full Analysis Set (FAS): The FAS population includes all randomized patients who took at least 1 dose of study medication and had a baseline (BL) value and at least one post BL value. Post BL measurements up to 3 days following the last dose of double-blind study medication were included in the analysis.
