About this study

This is a prospective, multi-center, observational registry to document the baseline, 24-hour and 30-day inflammatory response and procedural outcomes out to 12 month follow-up after femoropopliteal angioplasty or atherectomy-based revascularization procedures.

Read the detailed description

This is a prospective, multi-center, observational registry to document the baseline, 24-hour and 30-day inflammatory response and procedural outcomes out to 12 month follow-up after femoropopliteal angioplasty or atherectomy-based revascularization procedures.

  1. To observe the femoropopliteal revascularization outcomes post-angioplasty and/or atherectomy and to observe potential correlation between patency outcomes and the levels of MCP-1, C-reactive protein and MMP-9 from baseline to 24 hours and 30 days post-procedure.
  2. To provide a comparator dataset to the investigational DANCE trial, which has the same enrollment criteria as this observational trial but includes the investigational use of a local drug therapy to limit inflammation caused by mechanical revascularization.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT02469532
Study groupRoleWhat they receive
AtherectomyUp to 20 atherectomy procedures at up to 5 sites in the United States. Change in inflammatory biomarkers (hs-CRP, MCP-1 and MMP-9) from baseline to 24 hours post-procedure and 30-days post-revascularization procedure. This registry will also observe outcomes (target lesion revascularization rates, 6 and 12 month duplex ultrasound-detected binary restenosis with PSVR>2.4) post-atherectomy revascularization procedures.
Receives: Device: Atherectomy System
AngioplastyUp to 20 angioplasty procedures at up to 5 sites in the United States. Change in inflammatory biomarkers (hs-CRP, MCP-1 and MMP-9) from baseline to 24 hours post-procedure and 30-days post-revascularization procedure. This registry will also observe outcomes (target lesion revascularization rates, 6 and 12 month duplex ultrasound-detected binary restenosis with PSVR>2.4) post-angioplasty revascularization procedures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in inflammatory biomarkers

    Change in inflammatory biomarkers (hs-CRP, MCP-1 and MMP-9) from baseline to 24 hours post-procedure and 30-days post-revascularization procedure.

    Measured: Baseline to 24-hours post-procedure and 30-days post-procedure

Secondary outcomes (2)
  1. Target Lesion Revascularization

    This registry will prospectively collect data from patients diagnosed with peripheral arterial disease to observe the restenosis rates in peripheral arteries compared with subjects enrolled in the DANCE trial (Mercator MedSystems TSP0149).

    Measured: 6 and 12 months post-procedure

  2. Comparing biomarker (hs-CRP, MCP-1 and MMP-9) results

    This registry will prospectively collect data from patients diagnosed with peripheral arterial disease to observe the correlation between the levels of MCP-1, C-reactive protein and MMP-9 after angioplasty or atherectomy procedures in peripheral arteries compared with subjects enrolled in the DANCE trial (Mercator MedSystems TSP0149). Objective measurement of biomarkers will be performed by a contract laboratory to avoid bias.

    Measured: Baseline to 24 hours post-procedure and 30-days post-revascularization procedure

Questions about this trial

What is this clinical trial studying?

An observational study of Peripheral Arterial Disease, run by Mercator MedSystems, Inc. at 6 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 10 inclusion and 22 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: finished, as of the sponsor's last update on 8 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in inflammatory biomarkers (time frame: Baseline to 24-hours post-procedure and 30-days post-procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Mar 2018.
