Condition or disease | Intervention/treatment | Phase |
---|---|---|
Peripheral Arterial Disease | Drug: Placebo + background APT + SMT Drug: Vorapaxar 2.08 mg/d + background APT + SMT. | Phase 4 |
Primary trial objective: To evaluate whether addition of Vorapaxar 2.08 mg daily vs. placebo daily on background antiplatelet therapy, prescribed for 6 months to patients with established PAD and IC treated with standard medical therapy (SMT) would lead to an improvement in the peak walking time (PWT)
Study endpoints Primary endpoint: Change from baseline to 6 months in the PWT on a graded treadmill test (GTT per Gardner protocol) between participants enrolled in the test and control arms of the study
Secondary endpoints
- Change from baseline to 6 months in the claudication onset time (COT) on GTT between participants enrolled in the test and control arms of the study.
- Change from baseline to 6 months in the walking impairment questionnaire distance scores (WIQ) between participants enrolled in the test and control arms of the study.
- Change from baseline to 6 months in self-reported quality of life score using the Medical Outcomes Study 12-Item Short form survey (SF-12) between participants enrolled in the test and control arms of the study
Tertiary endpoints
- The first occurrence of clinically indicated lower extremity endovascular or surgical revascularization procedure during the entire study duration post-randomization in participants enrolled in the test or control arms of the study.
- The first occurrence of all-cause death, MI, ischemic stroke during the entire study duration post-randomization in participants enrolled in the test or control arms of the study.
- The first occurrence of severe bleeding defined according to the Global Utilization of Streptokinase and Tissue plasminogen activator for Occluded coronary arteries (GUSTO) classification during the entire study duration post-randomization in participants enrolled in the test or control arms of the study.
