PCI (optimal catheter-based coronary revascularization) + intensive medical therapy is superior to intensive medical therapy alone using the combined endpoint of all-cause mortality or nonfatal MI.

Study Type: | Interventional |
Study Design: | Randomized, Open Label, Uncontrolled, Single Group Assignment, Efficacy Study |
Official Title: | CSP#424 - Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation |
Estimated Enrollment: | 3260 |
Study Start Date: | December 1998 |
Estimated Study Completion Date: | June 2006 |
Primary Hypothesis: The strategy of PCI plus intensive medical therapy will be superior to intensive medical therapy alone in reducing all cause mortality or nonfatal MI in patients with documented myocardial ischemia who meet an AHA task force Class I indication for PCI.
Secondary Hypotheses: Resource utilization and QOL comparisons and hospitalization for acute coronary syndromes will be superior in PCI plus medical therapy compared to medical therapy alone.
Primary Outcomes: All cause mortality, nonfatal MI.
Interventions: All patients will be treated with intensive medical therapy. In addition half of them will receive percutaneous coronary intervention (PCI).
Study Abstract: The COURAGE Trial is a large-scale, multicenter, randomized controlled trial comparing medical therapy and PCI plus medical therapy that is powered for "hard" clinical endpoints. Patients eligible for inclusion in COURAGE will comprise all but very high-risk subjects, and will include those with chronic angina pectoris (Canadian Cardiovascular Society [CCS] Class I-III), recent uncomplicated MI, and asymptomatic (or "silent") myocardial ischemia. Patients may have single- or multi-vessel coronary artery disease and may have had prior bypass graft surgery or PCI. We project cumulative 3-year event rates of 16.4% and 21%, respectively, which yields an absolute difference of 4.6% or relative difference of 22%. With a minimum duration of follow-up of 2 1/2 years, a maximum of 7 years, using a two-sided test of significance at the 0.05 level, and assuming a 3% crossover rate then 2% then 1% each for 2 years from meds to PCI, and annual loss to follow-up rate of 1% these event rates indicate that a sample size of 2,270 will be needed to test the hypothesis with 85% power. Fifteen VA, 19 U.S. non-VA, and 16 Canadian sites enrolled in the study. The planned study duration was 7 years, with 4 1/2 years of patient intake and 2 1/2 - 7 years of follow-up. Study operations began in January 1999 and enrollment began in June 1999. The Data and Safety Monitoring Board approved reducing the sample size to 2,270 subjects based on increasing the length of randomization and follow-up and updating the definition of MI to include biomarker positive (troponin) ACS. Enrollment is complete with 2,287 patients enrolled.

Accepts Healthy Volunteers: | No |
It is important to emphasize that as many types of CAD patients as possible--reflecting the spectrum of patients encountered in contemporary clinical practice--will be enrolled in COURAGE.
