Trial Outcomes & Findings for Safety Study of Deoxycholic Acid for the Reduction of Localized Subcutaneous Fat in the Submental Area in Subjects 65 to 75 Years of Age (NCT NCT02123134)

NCT ID: NCT02123134

Last Updated: 2020-02-17

Results Overview

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). The participant evaluated their chin and neck area using the Patient-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=no chin fat at all (best) to 4= a very large amount of chin fat (worst).

PRIMARY outcome

Timeframe: Baseline and up to Week 32 (12 weeks after last treatment)

Population: Intent-to treat (ITT) population included all randomized participants, whether or not they received the assigned study drug.

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). The participant evaluated their chin and neck area using the Patient-Reported Submental Fat Rating Scale (a 5-point scale) where: 0=no chin fat at all (best) to 4= a very large amount of chin fat (worst).

The SMSLG is an integration of three features: skin wrinkling, adherence to underlying neck structures (bone and muscle) and redundancy (horizontal and vertical folds). Each grade (1=none, 2=mild, 3=moderate and 4=severe) defines the maximal allowed limit for skin wrinkling, adherence to underlying structures and redundancy.
