- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: Commercial claims of patients who underwent endovascular interventional treatment of the femoral or popliteal arteries for symptomatic PAD between 1/1/15 and 12/31/2019 will form the study population. Three separate safety analyses will be performed. 1. Paclitaxel Drug coated balloons (DCB) as compared with propensity-matched patients treated with plain transluminal balloon angioplasty (PTA). 2. Paclitaxel delivering Drug-Eluting Stents (DES) as compared with propensity-matched cases using bare-metal stents (BMS). 3. Patients treated with either paclitaxel DCB or paclitaxel DES (any PTX) compared with propensity-matched controls (non-PTX,with DCB patients, matched to patients treated with PTA, and DES patients matched to patients treated with BMS).
Who may be able to join
- All patients, age 18 or older, who had a health insurance claim for outpatient endovascular treatment of the femoral or popliteal arteries for symptomatic PAD will be included. The diagnosis and treatment of PAD in the femoral and popliteal arteries will be identified by CPT/HCPCS and ICD-9 and ICD-10 PCS codes.
- Presence of at least one additional outpatient or inpatient claims, at least 12 months following the index procedure, in order to demonstrate continued enrollment in health insurance coverage.
Who cannot join
- Age <18 years
- No qualifying peripheral arterial endovascular procedure
- Inpatient procedure
- Patients without any linked claim record more than 12 months after the index procedure, not known to have died or entered hospice care within the first 12 months

About this study
Treatment with paclitaxel-based endovascular devices (PED) has become a common treatment option for patients with peripheral artery disease (PAD) involving the femoral-popliteal artery. However, an aggregate level meta-analysis identified an association between the use of PED and increased all-cause mortality at both two and five-year follow-up intervals, though there are significant limitations of these analyses. Exploration of real-world data has been suggested as a means to further investigate the safety of PED. The current study explores the association of PED and mortality in real-world data using U.S. commercial claims from the FAIR Health data warehouse.

Treatment with paclitaxel-based endovascular devices (PED) has become a common treatment option for patients with peripheral artery disease (PAD) involving the femoral-popliteal artery. However, an aggregate level meta-analysis identified an association between the use of PED and increased all-cause mortality at both two and five-year follow-up intervals, though there are significant limitations of these analyses. Exploration of real-world data has been suggested as a means to further investigate the safety of PED. The current study explores the association of PED and mortality in real-world data using U.S. commercial claims from the FAIR Health data warehouse.
This study aims to evaluate the relative safety of paclitaxel used as an antiproliferative agent in the treatment of symptomatic PAD in a real-world scenario. We will analyze Paclitaxel Drug-Coated Balloons (DCB) and Paclitaxel Drug-Eluting Stents (DES), in aggregate and as unique exposures using propensity score-matched survival analysis. (Inverse probability of Treatment Weighting).
Commercial claims of patients who underwent endovascular interventional treatment of the femoral or popliteal arteries for symptomatic PAD between 1/1/15 and 12/31/2019 will form the study population. Three separate safety analyses will be performed. 1. Paclitaxel Drug coated balloons (DCB) as compared with propensity-matched patients treated with plain transluminal balloon angioplasty (PTA). 2. Paclitaxel delivering Drug-Eluting Stents (DES) as compared with propensity-matched cases using bare-metal stents (BMS). 3. Patients treated with either paclitaxel DCB or paclitaxel DES (any PTX) compared with propensity-matched controls (non-PTX,with DCB patients, matched to patients treated with PTA, and DES patients matched to patients treated with BMS).
All proposed analyses will be performed using R 4.01 implemented within the DELTA analytic engine. DELTA is an active surveillance safety system that can monitor clinical data repositories for safety signals and has been validated to support risk-adjusted prospective safety surveillance analyses of complex clinical datasets.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Treatment with paclitaxel-based endovascular devices (PED) has become a common treatment option for patients with peripheral artery disease (PAD) involving the femoral-popliteal artery. However, an aggregate level meta-analysis identified an association between the use of PED and increased all-cause mortality at both two and five-year follow-up intervals, though there are significant limitations of these analyses. Exploration of real-world data has been suggested as a means to further investigate the safety of PED. The current study explores the association of PED and mortality in real-world data using U.S. commercial claims from the FAIR Health data warehouse.

Questions about this trial
What is this clinical trial studying?
An observational study of Peripheral Arterial Disease, run by Lahey Clinic 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 4 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 14 Feb 2022. 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?
Survival (time frame: 4 years post intervention). 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 NCT04647643, which also lists 13 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 14 Feb 2022.
