June 26, 2025 updated by: 10xBio, LLC

A Multi-Center, Randomized, Double-Blinded, Vehicle-Controlled Study of the Safety and Efficacy of 10XB-101 in Adult Subjects With Submental Fat

The purpose of this research study is to determine the safety and efficacy of 10XB-101 vs. vehicle (placebo) for adults with excessive submental fat (SMF).

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.

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:

  • Subject is a male or non-pregnant female 18 to 65 years old.
  • Subject has provided written informed consent.
  • Subject has qualifying Submental Fat evaluation score.
  • Subject has had a stable body weight for the past 6 months prior to starting study.
  • Subject is willing to undergo test article injections as directed, comply with study instructions, and commit to all follow-up visits for the duration of the study.

Exclusion Criteria:

  • Subject is pregnant, lactating, or is planning to become pregnant during the study.
  • Subject has loose skin in the submental area, diffuse SMF, or prominent platysmal bands at rest that may interfere with evaluation of localized fat, in the opinion of the investigator.
  • Subject has had any prior treatment for SMF (e.g., deoxycholic acid, cryotherapy, liposuction, surgery).
  • Subject has any medical condition that affects clotting and/or platelet function
  • Subject has a history of allergy or sensitivity to polidocanol or any of the other ingredients in the test articles.

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
Clinician Submental Fat Scale (CSFS)
Time Frame: 24 weeks after final injection treatment
Change from Baseline after final treatment. CSFS is a 5 point scale, with a higher score indicating higher severity
24 weeks after final injection treatment
Patient Submental Fat Scale (PSFS)
Time Frame: 24 weeks after final injection treatment
Change from Baseline after final treatment. PSFS is a 5 point scale, with a higher score indicating higher severity
24 weeks after final injection treatment
