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.

Detailed Description

A total of approximately 300 adult participants that has received at least one study drug treatment and completed one follow-up visit in the parent studies will be enrolled. Each participant will undergo three follow-up visits, scheduled every three months in Stage 1.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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
Time Frame
Percentage of participants with at least 1 TEAE
Time Frame: 6,9, and 12 months after last treatment of parent studies
6,9, and 12 months after last treatment of parent studies

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
Percentage of participants with at least 1 AESI
Time Frame: 6,9, and 12 months after last treatment of parent studies
6,9, and 12 months after last treatment of parent studies
Percentage change from baseline in abdominal fat
Time Frame: From baseline to 6,9, and 12 months after last treatment in parent studies
Measured by MRI
From baseline to 6,9, and 12 months after last treatment in parent studies
Percentage of participants who maintain at least a 1-grade improvement on both Participant Reported Abdominal Fat Rating Scale (PR-AFRS) and Clinician Reported Abdominal Fat Rating Scale (CR-AFRS)
Time Frame: From baseline to 6,9, and 12 months after last treatment in parent studies
Measured by 5-point ordinal scales from Grade 1 to Grade 5 for assessing the severity of abdominal fat. The higher the grade, the more the abdominal fat.
