Overview
Brief Summary
To demonstrate the effectiveness of Restylane Defyne for chin augmentation and correction of chin retrusion by demonstrating the superiority in responder rates relative to no treatment.
Detailed Description
This was a randomized, no-treatment-controlled, evaluator-blinded, multi-center study to evaluate the effectiveness and safety of Restylane Defyne in the chin for augmentation and correction of chin retrusion.
This study was designed to enroll and randomize approximately 140 subjects in a 3:1 ratio of treatment to Restylane Defyne or no-treatment-control, including at least 21 subjects of Fitzpatrick skin type IV through VI. All randomized subjects were to have a Galderma Chin Retrusion Scale (GCRS) score of 1 (Mild) or 2 (Moderate).
Eligible subjects randomized to receive treatment were injected by the Treating Investigator at Day 1. The method of injection was at the discretion of the Treating Investigator. A sufficient amount of product was injected to achieve optimal correction of the chin, in the opinion of the Treating Investigator and subject. Optimal appearance was defined as at least 1 GCRS grade improvement from baseline and the best correction that could be achieved as agreed by the Treating Investigator and the subject.
At the 48-week visit, after all study procedures for the visit were completed, treated subjects had the option of receiving an additional treatment if optimal aesthetic improvement was not maintained with Restylane Defyne. Non-treated control subjects also had the option of receiving treatment with Restylane Defyne in the chin at Week 48. If an optional treatment was performed, a safety follow-up visits were scheduled

Outcomes
Primary Outcomes
Evaluate Effectiveness of the Treatment Using the Galderma Chin Restrusion Scale
Time Frame: 12 weeks after baseline
subjects achieving at least 1-grade improvement from baseline using the Galderma Chin Retrusion Scale (GCRS; 0=no retrusion, 1=mild retrusion, 2=moderate retrusion, 3=substantial retrusion) as assessed by blinded evaluator
Secondary Outcomes
- Evaluate Effectiveness of the Treatment Using the Galderma Chin Retrusion(24, 36, and 48 weeks after last injection)
- Assess Overall Aesthetic Improvement Using the Global Aesthetic Improvement Scale(12, 24, 36, and 48 weeks after last injection)
- Evaluate Subject Satisfaction Using the FACE-Q (Baseline to Week 12)(12 weeks after last injection)
- Evaluate Volume Change in the Treated Area Using 3D Imaging(12, 24, 36, and 48 weeks after last injection)
- Evaluate Subject Satisfaction Using the FACE-Q (From Baseline to Week 24)(24, 36, and 48 weeks after last injection)
