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

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)

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
Change in Waist Circumference 12 Weeks After Treatment as Compared to Baseline
Time Frame: 12 weeks
Change from baseline in waist circumference 12 weeks after treatment was assessed by blinded evaluators.
12 weeks

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
Time Frame
Change in Waist Circumference 4,8, and16 Weeks After Treatment as Compared to Baseline
Time Frame: 4 weeks, 8 weeks, 16 weeks
Change from baseline in waist circumference 4, 8, and 16 weeks after treatment was assessed by blinded evaluators.
4 weeks, 8 weeks, 16 weeks
Investigator Assessment of Improvement Using Global Aesthetic Improvement Scale (GAIS)
Time Frame: 4, 8, 12, and 16 weeks

GAIS evaluations were performed by Investigators at the 4, 8, 12, and 16 week visits. Investigators used direct visual assessment (live assessment) compared to photographs of subjects taken before treatment (baseline) to assess improvement in the treatment area.

Scoring was based upon a five point grading System: 5 - Much Improved, 4 - Improved, 3 - No Change, 2 - Worse, or 1 - Much Worse. The definition of an improvement of the GAIS score included either a GAIS score of 'Improved' or 'Much Improved'.
4, 8, 12, and 16 weeks
Subject Assessment of Improvement Using Global Aesthetic Improvement Scale (GAIS)
Time Frame: 4, 8, 12, and 16 weeks
Subjects self-assessed improvement in the treatment area and assigned a GAIS score at each visit. Scoring was based upon a five point grading System: 5 - Much Improved, 4 - Improved, 3 - No Change, 2 - Worse, or 1 - Much Worse. The definition of an improvement of the GAIS score included either a GAIS score of 'Improved' or 'Much Improved'.
4, 8, 12, and 16 weeks
Subject Satisfaction With Treatment
Time Frame: 4, 8, 12, and 16 weeks
Subjects rated their satisfaction with treatment results using a 5-point Likert Satisfaction Scale (5: very satisfied; 4: satisfied; 3: neither satisfied nor dissatisfied; 2: dissatisfied; 1: very dissatisfied). The subject satisfaction score was analyzed as the proportion of subjects showing improvement as defined as a score of 4 or greater ('satisfied' or 'very satisfied').
