Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.
Interventional

Enrollment (Actual)

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.

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 to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria

  1. Male or female subjects > 18 years of age and < 65 years of age.
  2. Subject has clearly visible fat on intended treatment area, which in the investigator's opinion, may benefit from the treatment(s).
  3. Subject has not had weight change exceeding 10 pounds in the preceding month.
  4. Subject with body mass index (BMI) less than 30. BMI is defined as weight in pounds multiplied by 703 divided by the square of the height in inches.
  5. Subject agrees to maintain his/her weight (i.e., within 5 pounds) by not making any major changes in their diet or lifestyle during the course of the study.
  6. Subject has read and signed a written informed consent form.

Exclusion Criteria

  1. Subject presents a significant asymmetry of intended treatment areas.
  2. Subject has had a surgical procedure(s) in the area of intended treatment in the past 5 years.
  3. Subject has had an invasive fat reduction procedure (e.g., liposuction, abdominoplasty, mesotherapy) in the area of intended treatment in the past 5 years.
  4. Subject has had a non-invasive fat reduction and/or body contouring procedure in the area of intended treatment within the past 6 months.
  5. Subject needs to administer, or has a known history of subcutaneous injections into the area of intended treatment (e.g., heparin, insulin) within the past month.
  6. Subject has a known history of cryoglobulinemia, cold urticaria, or paroxysmal cold hemoglobinuria.
  7. Subject has a known history of Raynaud's disease, or any known condition with a response to cold exposure that limits blood flow to the skin.
  8. Subject has a history of bleeding disorder or is taking any medication that in the investigator's opinion may increase the subject's risk of bruising.
  9. Subject is taking or has taken diet pills or weight control supplements within the past month.
  10. Subject has any dermatological conditions, such as moderate to excessive skin laxity, or scars in the location of the treatment sites that may interfere with the treatment or evaluation (stretch marks is not an exclusion).
  11. Subject has an active implanted device such as a pacemaker, defibrillator, or drug delivery system.
  12. Subject is pregnant or intending to become pregnant in the next 5 months.
  13. Subject is lactating or has been lactating in the past 6 months.
  14. Subject has a history of hernia in the areas to be treated.
  15. Subject is unable or unwilling to comply with the study requirements.
  16. Subject is currently enrolled in a clinical study of any other unapproved investigational drug or device.
  17. Any other condition or laboratory value that would, in the professional opinion of the investigator, potentially affect the subject's response or the integrity of the data or would pose an unacceptable risk to the subject.

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
Percentage of Before and After Side-by-side Photographs Correctly Identified by At Least 2 of 3 Blinded Reviewers From the Independent Physician Reviewer (IPR) Panel
Time Frame: Baseline, Week 16
Photographs of the treatment areas were taken at baseline, and at 16-weeks after the first treatment with the ZELTIQ System were assessed for any visual changes. The photographs were assessed by blinded independent reviewers (IPR) to correctly identify the 16-weeks post-treatment photographs from randomly placed side-by-side comparison of before and after photographs. Reported here is the percentage (%) of images that were correctly identified by at least 2 out of 3 blinded independent reviewers.
Baseline, Week 16

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
Time Frame
Change From Baseline in Reduction of Fat Layer Thickness as Assessed by Ultrasound
Time Frame: Baseline, Week 16
