Trial Summary

What is the purpose of this trial?

The masseter muscle is one of the muscles in the lower face used for chewing. The prominence of the masseter muscle can appear as a widened lower face which some individuals deem as aesthetically undesirable and can be treated by selectively weakening the masseter muscles with small quantities of botulinum toxin. The purpose of this study is to assess how safe and effective injection of onabotulinumtoxinA (BOTOX) is in adult participants with Masseter Muscle Prominence (MMP). BOTOX is being investigated for the treatment of Muscle Masseter Prominence. In Period 1, participants are placed in 1 of 2 groups, called treatment arms. Each group receives a different treatment, placebo or BOTOX. There is a 1 in 4 chance that participants will be assigned to placebo. In Period 2, eligible participants can receive an optional open-label retreatment of BOTOX. Approximately 200 adult participants with MMP will be enrolled in the study at approximately 20 sites in the United States. Participants will receive intramuscular injections across both the right and left masseter muscle of either BOTOX or placebo on Day 1. Participants who are eligible for re-treatment will be given a BOTOX injection on either the Day 180, 210, 240, or 270 visit and will be followed up for up to 6 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular monthly visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects, and completing questionnaires.

Eligibility Criteria

Adults with Masseter Muscle Prominence, which causes a widened lower face, can join this study. They must be willing to receive injections and attend monthly visits at the clinic or hospital. People who don't meet these requirements or have conditions that could interfere with the trial may not participate.

Inclusion Criteria

Investigator and participant scoring of MMPS and MMPS-P must be the same

My jaw muscles are very prominent, rated as the highest on a specific scale.

Participant's Body mass index (BMI) must be ≤ 30 kg/m^2

Exclusion Criteria

I have or might have jaw joint (TMJ) problems.

Asymmetry of left and right sides of the face that could prevent identical MMPS or MMPS-P grading on both sides of the face

I have noticeable lower facial fat or loose skin that might affect facial grading.

Treatment Details

Interventions

• BOTOX (Neuromodulator)

Trial Overview The trial is testing BOTOX injections against a placebo to see if they can safely reduce the size of masseter muscles in adults. Participants are randomly assigned to get either BOTOX or a placebo, with a follow-up period where eligible participants might receive additional BOTOX treatments.

Participant Groups

Group I: Open-Label Period: BOTOX Experimental Treatment 1 Intervention

Participants who are eligible for re-treatment will receive BOTOX injections on either the Day 180, 210, 240, or 270 visit and will be followed for up to 6 months.

Group II: Double-Blind Period: BOTOX Experimental Treatment 1 Intervention

Participants will receive BOTOX injections across both the right and left masseter muscle on Day 1.

Group III: Double-Blind Period: Placebo Placebo Group 1 Intervention

Participants will receive placebo injections across both the right and left masseter muscle on Day 1.
