About this study
Official title: Vascular Trial Associated Registry Pilot: Antiplatelet Therapies for Patients Undergoing Lower Extremity Endovascular Revascularization
The purpose of this investigator-initiated, multicenter, open label, randomized trial is to evaluate 1 month vs. 6 months of dual antiplatelet therapy (DAPT) in patients undergoing lower extremity endovascular revascularization. We hypothesize that extending dual antiplatelet therapy (DAPT) to six months, compared to one month, will improve patency rates of target vessels following peripheral vascular intervention (PVI) without significantly increasing complications, particularly bleeding events.
Read the detailed description
The Main Objective of this study is to create an investigator-initiated, multicenter, open label, randomized trial to evaluate 1 month vs. 6 months of DAPT in patients undergoing lower extremity endovascular revascularization. The randomization will be 1:1 within one strata (diabetes yes/no), using blocks of varying sizes. All patients will be on DAPT for one month. At the time of the one-month visit, eligible patients who consent will be randomized to single antiplatelet therapy (SAPT) indefinitely (Arm 1) or to DAPT for 5 more months (followed by SAPT) (Arm 2). Follow-up will continue for 12-months post-procedure and will include assessment of MACE and MALE, as well as adverse bleeding events. Data for this trial will be collected via nested participation in the VQI Peripheral Vascular Intervention (PVI) registry's existing Procedural and Follow-up data collection modules.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Clopidogrel (Plavix) Pharmacogenetic Test Reagents in people with Peripheral Arterial Disease, run by Corewell Health West at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 16 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Stephen C Orey, MS (6163916660, Stephen.orey@corewellhealth.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The proportion of patients eligible who are offered study enrollment (time frame: 1 year). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07076082, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jul 2026.
