NCT02660866

Brief Summary

This is a Phase 4, randomized clinical trial 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 peripheral artery disease (PAD) and Intermittent Claudication (IC) treated with standard medical therapy (SMT) would lead to an improvement in the peak walking time (PWT).

Outcome Measures

Primary Outcomes (1)

  • 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

    6 months

Secondary Outcomes (1)

  • 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.

PLACEBO COMPARATOR

Standard Medical Therapy (SMT): Presence of any two of the listed classes of agents \[angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), statin therapy and beta-blocker drugs\] + ability to perform at least 15 min of home walking a day, at least 3 times/week, at ≥20 steps/min Background Antiplatelet Therapy (APT) :At least one aspirin dose within 5 days prior to randomization at 325 mg dose in aspirin naïve patients (0-5 days of prior aspirin use) or at least one aspirin dose within 5 days prior to randomization at 81 mg dose in patients on chronic (\>5 days of prior use) aspirin therapy.

Drug: Placebo + background APT + SMTDrug: Vorapaxar 2.08 mg/d + background APT + SMT.
