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

14 years to 61 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Moderate or severe submental fat
  • Dissatisfaction with submental area
  • History of stable body weight

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 From Baseline in Clinician-Reported Submental Fat Rating Scale Scores
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
The CR-SMFRS score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme. A negative change from Baseline indicates improvement.
Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Change From Baseline in Patient-Reported Submental Fat Scale Rating Scale (PR-SMFRS)
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
The PR-SMFRS is based on the participant's response to the question "How much fat do you have under your chin right now?" answered on a 5-point ordinal scale (0-4) with 0 = no chin fat at all, 1 = a slight amount of chin fat, 2 = a moderate amount of chin fat, 3 = a large amount of chin fat, and 4 = a very large amount of chin fat. A negative change from Baseline indicates improvement.
Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Change From Baseline in Patient-Reported Submental Fat Impact Scale (PR-SMFIS)
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
The PR-SMFIS assesses the impact of submental fat on self-perception of 6 emotional and visual characteristics related to the appearance of submental fullness (unhappy, bothered, self-conscious, embarrassed, look older, and look overweight) as evaluated by the participant. Each item is rated on an 11-point numeric scale from 0 to 10. Scores for the 6 items were averaged to generate a PR-SMFIS total scale score ranging from 0 to 10 where 0 is a positive outcome and 10 is a negative outcome. A negative change from Baseline indicates improvement.
Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)

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 From Baseline in Submental Fat Volume
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Submental fat volume was measured by magnetic resonance imaging (MRI).
Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Change From Baseline in Submental Fat Thickness
Time Frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Submental fat thickness was measured by magnetic resonance imaging (MRI).
Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
