Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 66 years and older
  • All sexes
  • No healthy volunteers
  • Older adult

Study population: The study cohort will include all Medicare fee-for-service beneficiaries who underwent femoropopliteal artery revascularization with either drug-coated devices (drug-eluting stent [DES] ± drug-coated balloon [DCB], bare metal stent [BMS] with DCB, or DCB alone) or non-drug-coated devices (BMS ± percutaneous transluminal angioplasty [PTA] or PTA alone). Each group will additionally be composed of two device-specific subgroups: a DCB sub-group and DES sub-group in the drug-coated group, and a PTA sub-group and a BMS sub-group in the non-drug group.

Who may be able to join

  • All fee-for-service Medicare beneficiaries who underwent femoropopliteal artery revascularization. Patients are allowed to undergo simultaneous revascularization of lesions outside this target vessel during the same procedure.
  • All patients with ≥1 year of Medicare claims data prior to their index procedure.

Who cannot join

  • Patients without 1 year of Medicare claims data prior to their index revascularization procedure.
  • Patients that do not have both a carrier file charge and an institutional file charge on the date of an outpatient procedure. This removes procedures performed in certain clinical settings, such as office-based clinics, that do not submit the Healthcare Common Procedure Coding System (HCPCS) code needed to identify drug-coated devices.

About this study

The SAFE-PAD Study aims to evaluate the long-term safety of paclitaxel-coated devices compared with non-paclitaxel-coated devices for femoropopliteal artery revascularization among a broad, real-world population of patients with peripheral artery disease. This multi-year analysis aims to create an ongoing mechanism to evaluate the safety of paclitaxel-coated devices in real world practice. The null hypothesis is that the paclitaxel-coated devices are associated with an increase in mortality relative to the non-drug-coated devices beyond an acceptable magnitude (i.e. the non-inferiority margin), and the alternative hypothesis is that paclitaxel-coated devices are not associated with an increase in mortality relative to the non-drug-coated devices beyond the non-inferiority margin.

Read the detailed description

This is an observational retrospective cohort study using claims data to evaluate the long-term safety of paclitaxel-coated devices compared with non-drug coated devices for femoropopliteal artery revascularization, with median follow-up time for the population surpassing 5 years. A series of supplemental sensitivity analyses will be conducted to assess and mitigate the potential for unmeasured confounding and to determine the impact of repeat interventions and paclitaxel exposure on survival. Finally, sub-group analyses will be performed to investigate whether there is differential safety of paclitaxel-coated devices across different patient profiles.

What is being measured

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

  1. All-cause mortality

    All-cause mortality of patients who underwent femoropopliteal artery revascularization with drug-coated devices or non-drug-coated devices

    Measured: Time from index procedure date to the date of death, to be updated periodically until the median duration of follow-up for the cohort reaches 5 years

Secondary outcomes (5)
  1. Repeat hospitalization

    Rates of repeat hospitalization

    Measured: 1, 2 and 3 years after index procedure

  2. Repeat endovascular or surgical revascularization

    Rates of repeat endovascular or surgical revascularization

    Measured: 1, 2 and 3 years after index procedure

  3. Target vessel revascularization

    Rates of target vessel revascularization among inpatient procedures

    Measured: 1, 2 and 3 years after index procedure

  4. Lower extremity amputation

    Rates of lower extremity amputation

    Measured: 1, 2 and 3 years after index procedure

  5. Optimal medical therapy

    Rates of optimal medical therapy

    Measured: 1, 2 and 3 years after index procedure

Questions about this trial

What is this clinical trial studying?

An observational study of Peripheral Arterial Disease and Paclitaxel Adverse Reaction, run by Beth Israel Deaconess Medical Center at 1 site 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 2 inclusion and 2 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 9 Aug 2024. 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 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?

All-cause mortality (time frame: Time from index procedure date to the date of death, to be updated periodically until the median duration of follow-up for the cohort reaches 5 years). 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 NCT04496544, which also lists 2 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 9 Aug 2024.
