Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
50

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  2. Male or female subject of at least 18 years of age.
  3. Chronic symptomatic lower limb ischemia defined as Rutherford classification 2, 3, or 4.
  4. Has screen failed from the ACTIVATE II study due to the presence of Grade C or D dissection(s).

Exclusion Criteria:

  1. Life expectancy, documented in the Investigator's opinion, of less than 1 year.
  2. Cerebrovascular accident (CVA) or transient ischemic attack (TIA) or cardiac event (e.g., PCI for STEMI/NSTEMI, unstable angina) within 6 months prior to the index procedure.
  3. Chronic renal insufficiency with serum creatinine ≥ 2.5 mg/dL or eGFR <45 ml/min within 30 days prior to the index procedure or treatment with peritoneal or hemodialysis.

  5. Receiving oral or intravenous immunosuppressive therapy.
  6. Subject has white blood cell (WBC) count < 3.0 (3,000 cells/mm3) within 30 days prior to the index procedure.
  7. History of major amputation in the target limb.
  8. Any major intervention planned at the index procedure or within 30 days post-index procedure including treatment of contralateral limb.
  9. Subject is pregnant, breastfeeding, or planning to become pregnant in the next 30 days. Subjects (male and female) of childbearing potential must agree to use effective birth control measures for 30 days after the index procedure.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
An acute reduction in arterial dissections
Time Frame: 12 months
Reduction in arterial dissection(s) of at least one grade.
12 months
Primary Patency as assessed by Doppler Ultrasound (DUS) and freedom from CD-TLR at 1 Year
Time Frame: 12 months
Primary Patency as assessed by Doppler Ultrasound (DUS)
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
