January 11, 2021 updated by: Stavros Spiliopoulos, Attikon Hospital

Multi-center, Randomized Trial Comparing Dual Antiplatelet Therapy With CILOstazol Plus Aspirin Versus Aspirin Alone Following PERipheral Endovascular Procedures

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multi-center, randomized, single-blinded, phase III, controlled trial investigating the safety and effectiveness of dual antiplatelet therapy with cilostazol 100 mg twice daily and aspirin 100 mg daily versus monotherapy with aspirin 100 mg daily in patients undergoing peripheral, infrainguinal angioplasty or stenting or both for the management of peripheral arterial disease (intermittent claudication or critical limb ischemia). The study will include in total 200 patients randomized on a 1:1 basis to receive either dual antiplatelet therapy for 6 months cilostazol 100 mg once daily and aspirin 100 mg daily versus monotherapy with aspirin 100 mg daily for 12 months. The study's primary endpoint will be the composite of major adverse cardiovascular events (cardiovascular death, myocardial infarction, stroke, major amputation, target limb open surgical or endovascular revascularization). Additional therapy with clopidogrel 75mg daily will be added in either group for one month in case of stent placement. Secondary endpoints will include quality of life assessment using dedicated questionnaires, drug- and procedure-related complication rates, target-limb revascularization rates, clinical improvement (ABI and Rutherford-Becker classification changes). Clinical follow up will be performed at 1, 6 and 12 months and will include physical examination, ABI measurements, Rutherford-Becker classification. Maximum follow up period will be 2 years after the index procedure.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers
