Design outcomes

Primary

MeasureTime frameDescription
Percentage of Responders Based on Blinded Evaluators' Live Assessment of the Galderma Jawline Scale (GJS)At Month 3The GJS is a validated 5-point scale (ranges 0-4) for assessment of the jawline. Each score in the GJS is represented by photographic images of the scale, where 0 = none to minimal, 1 = mild, 2 = moderate, 3 = severe and 4 = very severe volume deficiency posterior to the jowl along the jawline. The Blinded Evaluator performed live assessment of the participant's left and right jawline separately. Here, a higher score indicated more volume deficiency in the treatment area. A responder was defined as a participant having at least a 1-grade improvement from baseline on both jawlines concurrently.

Recruitment details

This study was conducted at 15 investigative sites in the United States from 15 November 2021 to 23 October 2024.

Pre-assignment details

A total of 245 participants were screened for the study, of which 21 were screen failures. Of the 224 randomized participants, 56 were randomly assigned to the no treatment group and 168 were randomly assigned to receive GP0109 injection at baseline stratified by injection tool (needle, cannula and both needle and cannula combined) and Fitzpatrick skin type (FST) group (I-III, IV and V-VI).
