IMPROVE-IT: Examining Outcomes in Subjects With Acute Coronary Syndrome:Vytorin (Ezetimibe/Simvastatin) vs Simvastatin (Study P04103) - Full Text View

Purpose

This is a randomized, active-control, double-blind study of subjects with stabilized high-risk acute coronary syndrome (ACS). The primary objective is to evaluate the clinical benefit of Ezetimibe/Simvastatin Combination 10/40 (single tablet, under the brand VYTORIN in the United States) compared with Simvastatin 40 mg. If LDL-C response is inadequate, the dose of simvastatin in the VYTORIN arm or simvastatin arm, as appropriate, may be increased to 80 mg. Clinical benefit will be defined as the reduction in the risk of the occurrence of the composite endpoint of CV death, major coronary events, and stroke.

Official Title:	A Multicenter, Double-Blind, Randomized Study to Establish the Clinical Benefit and Safety of Vytorin (Ezetimibe/Simvastatin Tablet) vs Simvastatin Monotherapy in High-Risk Subjects Presenting With Acute Coronary Syndrome (IMProved Reduction of Outcomes: Vytorin Efficacy International Trial - IMPROVE IT)

Further study details as provided by Schering-Plough:

Primary Outcome Measures:

To measure the effect of treatment with ezetimibe/simvastatin compared with simvastatin monotherapy on death due to any cardiovascular events, non-fatal coronary events (such as heart attack), and non-fatal strokes [ Time Frame: Trial will continue until a minimum of 5,250 subjects have a primary endpoint event and each subject is followed for a minimum of 2.5 years. Thus, the anticipated completion dates below may be adjusted on the basis of actual event occurrence. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To measure the effect of treatment with ezetimibe/simvastatin compared with simvastatin monotherapy on death due to any cause, non-fatal coronary events (such as heart attack), and non-fatal stroke [ Time Frame: Trial will continue until a minimum of 5,250 subjects have an primary endpoint event and each subject is followed for a minimum of 2.5 years ] [ Designated as safety issue: No ]
To measure the effect of treatment with ezetimibe/simvastatin compared with simvastatin monotherapy on coronary heart disease-related death, non-fatal heart attack, and by-pass surgery [ Time Frame: Trial will continue until a minimum of 5,250 subjects have an primary endpoint event and each subject is followed for a minimum of 2.5 years ] [ Designated as safety issue: No ]
To measure the effect of treatment with ezetimibe/simvastatin compared with simvastatin monotherapy on death due to any cardiovascular events, non-fatal heart attack, angina leading to hospitalization, by-pass surgery, and non-fatal stroke [ Time Frame: Trial will continue until a minimum of 5,250 subjects have an primary endpoint event and each subject is followed for a minimum of 2.5 years ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
ezetimibe/simvastatin: Experimental	Drug: ezetimibe/simvastatin ezetimibe/simvastatin 10/40 mg per day from randomization through the end of participation (if LDL-C response is inadequate, the dose of simvastatin may be increased to 80 mg)
simvastatin: Active Comparator	Drug: simvastatin simvastatin 40 mg per day from randomization through the end of participation (if LDL-C response is inadequate, the dose of simvastatin may be increased to 80 mg)
