About this study

Official title: Vascular Implant Surveillance and Interventional Outcomes Network and the Vascular Quality Initiative Paclitaxel Safety Analysis

Objectives

  1. The VQI-VISION Paclitaxel Device Safety Analysis seeks to assess the comparative safety of paclitaxel-coated balloons and stents in the treatment of PAD through analysis of the Vascular Quality Initiative (VQI) Peripheral Vascular Intervention (PVI) registry module with linkage to claims. By linking VQI patients to Medicare claims retrospectively from 2012 to 2016, we will be able to identify additional paclitaxel devices enabling longitudinal follow-up of mortality out to 5 years for paclitaxel-eluting stents and 3 years for paclitaxel-coated balloons.
  2. To analyze factors associated with mortality, specifically comparing paclitaxel patients surviving vs. paclitaxel patients with mortality. The goal is to identify independent factors predictive of mortality in US pivotal trials and model registry data exposures with sufficient factors to track competing risk paradox and show emulation or not of mortality outcomes with both PTX and PTA exposures.
  3. To confirm the effectiveness of paclitaxel devices by comparing reintervention for paclitaxel and non-paclitaxel devices. In-hospital mortality from open and percutaneous target vessel revascularization (TVR) will be reported to determine the impact of subsequent revascularizations on survival. Major amputation will be comparted for patients with chronic limb-threatening ischemia.
Read the detailed description

The proposed safety analyses will evaluate two types of paclitaxel-coated interventional devices used to treat PAD and compare patient outcomes with propensity score-matched patients of similar risk who receive non-paclitaxel devices.

The primary outcome will be freedom from all-cause death using propensity-matched survival analysis.

Three principle analyses are planned:

  1. Paclitaxel DCB (including the Bard Lutonix, Medtronic In.Pact Admiral, and Philips Spectranetics Stellarex DCB's) as compared with propensity-matched patients treated with plain balloons.
  2. Paclitaxel delivering DES (Cook Zilver PTX) as compared with propensity-matched cases using bare-metal stents (BMS).
  3. Patients treated with either Paclitaxel DCB or Paclitaxel DES compared with propensity-matched controls (with DCB patients matched to patients treated with plain balloons, and DES patients matched to patients treated with BMS).

Note that this analysis is planned at the device class level and is not intended to compare early or late mortality between specific devices or brands.

Questions about this trial

What is this clinical trial studying?

An observational study of PAD, run by University of Vermont Medical Center.

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 5 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 19 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

overall mortality (time frame: 1 year). The study lists 3 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 NCT04204564, which also lists 15 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 19 Dec 2019.
