Trial summary

Interventional strategies aim to restore tissue perfusion. However, despite the simple reopening of a narrowed artery they affect endothelial function, perpetuating dysfunctional vascular homeostasis. PTA and atherectomy might alter the endothelial function but the mechanisms are incompletely understood. Read more about this study

About this study

Official title: Safety and Efficacy of Interventional Treatment Through Atherectomy to Improve Vascular Functions and Patency in Symptomatic Peripheral Artery Disease - Pilot Study

Interventional strategies aim to restore tissue perfusion. However, despite the simple reopening of a narrowed artery they affect endothelial function, perpetuating dysfunctional vascular homeostasis. PTA and atherectomy might alter the endothelial function but the mechanisms are incompletely understood. The primary goal of atherectomy is vessel preparation and improving compliance, which could aid in preserving vessel functions. Aim of this study is to determine safety, efficacy, patency and vessel functions in the femoropopliteal artery following atherectomy and DCB.

Being tested
Atherectomy, POBA and DCB
Medical subject headings
Peripheral Arterial Disease, Intermittent Claudication

What participants receive

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

  • AtherectomyOther

    Straub Rotarex S atherectomy and drug-coated balloon DCB. Predilation of the lesion with a predefined ballon (180 sec, Passeo-18). Thus, no direct DCB will be conducted. All DCB lengths (40mm to 200 mm) and Diameters (3mm to 7mm) are eligible for the Trial as long as used in the superficial femoral artery (SFA).

  • POBA and DCBOther

    Standard predilation (POBA) and DCB. Predilation of the lesion with a predefined ballon (180 sec, Passeo-18). Thus, no direct DCB will be conducted. All DCB lengths (40mm to 200 mm) and Diameters (3mm to 7mm) are eligible for the Trial as long as used in the superficial femoral artery (SFA).

What is being measured

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

  1. Treatment-Emerged Adverse Events

    Incidence of Treatment-Emerged Adverse Events as assessed by angiography and adverse event assessment

    Measured: 6 months Follow Up

  2. Primary patency

    determined through doppler ultrasound

    Measured: 6 months Follow Up

Secondary outcomes (8)
  1. Bail-out stent rate

    success of atherectomy in the SFA including the bail-out stenting rates

    Measured: 6 months Follow Up

  2. FMD local

    Local endothelial function and vasomotion testing as determinded by FMD of the femoral artery

    Measured: 6 months Follow Up

  3. Vessel stiffness

    Vascular stiffness determined through pulse wave velocity (PWV)

    Measured: 6 months Follow Up

  4. target lesion revascularization

    freedom from Target Lesion Revascularization (FTLR) is defined as the Need for percutaneous or interventional revascularization

    Measured: 6 months Follow Up

  5. ABI (Ankle Brachial Index)

    Ankle Brachial Index assessed by Doppler

    Measured: 6 months Follow Up

  6. Systemic endothelial function

    Change of endothelial function, assessed by the change in the vasodilation after reactive hyperaemia of the brachial artery (flow-mediated dilation = FMD)

    Measured: 6 months Follow Up

  7. Change in Plaque burden

    Change in plaque burden is measured by plaque volume change using intravascular ultrasound (IVUS)

    Measured: during baseline visit

  8. Change in plaque characteristic

    Change in plaque characteristic is quantified using virtual histology using intravascular ultrasound (IVUS)

    Measured: during baseline visit

Questions about this trial

What is this clinical trial studying?

A study testing Atherectomy and POBA and DCB in people with Peripheral Arterial Disease and Claudication, Intermittent, run by University Hospital, Essen at 1 site in Germany.

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 8 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 25 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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?

Results are not available in the source record.

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

Contact Christos Rammos (020172384808, Christos.Rammos@uk-essen.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Treatment-Emerged Adverse Events (time frame: 6 months Follow Up). The study lists 2 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 NCT04092972, which also lists 1 linked publication.

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 25 Jan 2021.
