Recruitment details

The objective of this non-treatment, double-blind, placebo-controlled follow-up study was to evaluate the long-term efficacy and safety of subcutaneous (SC) injections of deoxycholic acid (ATX-101) in the submental area. No treatment was administered in this study.

Pre-assignment details

Participants who previously received deoxycholic acid or placebo injections in studies ATX-101-11-22 and ATX-101-11-23 were enrolled in this non-treatment, double-blind, placebo-controlled follow-up study to further evaluate safety and efficacy.

The investigator evaluated the participant's chin and neck area using the Clinician-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=absent submental convexity (best) to 4= extreme submental convexity (worst). Non-responders at LTFU baseline in each treatment group (including placebo) were not included in the analysis.

Time frame: From 12 weeks after last treatment (in the predecessor study) to up to 36 months after last treatment

Population: Participants who had at least a 1-grade reduction from baseline on the CRSMFRS (ie, CR-1 responder) at 12-weeks after last treatment in the predecessor studies.
