Status Active, not recruiting

Clinical Trial Summary

The Ischemia-IMT (Ischemia-Intensive Medical Treatment Reduces Events in Women with Non-Obstructive CAD), subtitle: Women's Ischemia Trial to Reduce Events in Non-Obstructive CAD (WARRIOR) trial is a multicenter, prospective, randomized, blinded outcome evaluation (PROBE design) evaluating intensive statin/ACE-I (or ARB)/aspirin treatment (IMT) vs. usual care (UC) in 4,422 symptomatic women patients with symptoms and/or signs of ischemia but no obstructive CAD. The hypothesis is that IMT will reduce major adverse coronary events (MACE) 20% vs. UC. The primary outcome is first occurrence of MACE as death, nonfatal MI, nonfatal stroke/transient ischemic attack (TIA) or hospitalization for heart failure or angina. Secondary outcomes include quality of life, time to "return to duty"/work, health resource consumption, angina, cardiovascular (CV) death and primary outcome components. Events will be adjudicated by an experienced Clinical Events Committee (CEC). Follow-up will be 3-years using 50 sites: primarily VA and Active Duty Military Hospitals/Clinics and a National Patient-Centered Clinical Research Network (PCORnet) clinical data research network (CDRN)(OneFlorida Consortium).

This study is being conducted to determine whether intensive medication treatment to modify risk factors and vascular function in women patients with coronary arteries showing no flow limit obstruction but with cardiac symptoms (i.e., chest pain, shortness of breath) will reduce the patient's likelihood of dying, having a heart attack, stroke/TIA or being hospitalized for cardiac reasons. The results will provide evidence data necessary to inform future guidelines regarding how best to treat this growing population of patients, and ultimately improve the patient's cardiac health and quality of life and reduce health-care costs.

Clinical Trial Description

WARRIOR trial is a multi-site, PROBE design, that will evaluate an intensive statin/ACE-I (or ARB)/aspirin treatment strategy (IMT) vs. primary prevention risk factor therapy treatment strategy (UC) in 4,422 symptomatic (chronic angina or equivalent) women with non-obstructive CAD (<50% diameter narrowing).

There will be ~80 US sites, including VA/ military and OneFlorida CDRN sites, with a proven record in prior trials. The investigators will use web-based, real-time data entry, and management University of Florida Data Management System (UFDMS) for site selection, screening, participant eligibility confirmation, enrollment, and randomization. Participants will be recruited from screened women with symptoms suspected to be ischemic with non-obstructive CAD by invasive coronary angiogram or CT angiogram. The high dose statin (atorvastatin or rosuvastatin) and ACE-I (lisinopril) [or ARB (losartan)] are generic commonly used medications previously demonstrated effective for improving angina, stress testing, myocardial perfusion and coronary microvascular flow reserve in small size trials in this population. Additionally, aspirin will also be recommended to IMT participants without contraindications or excess bleeding risk, however aspirin will not be provided by the study. Both the groups will also receive Lifestyle Counseling (PACE Assessment), and the same visit schedule and "face-time" with site staff to reduce bias. Events will be adjudicated by the Clinical Events Committee (CEC), according to objective criteria and masked to treatment assignment clues. ;
