Study Endpoints

Primary Endpoints

Percentage of Participants Achieving "Responder" Status Based on the Evaluating Investigator's (EI) live assessment of Mid-Face Volume Deficit Scale (MFVDS)
Month 6

A "responder" is a participant with at least 1- grade improvement (reduction) of mid face soft tissue deficit using the MFVDS. MFVDS is a validated 6-point scale (0 = None, 5 = Severe).

Number of Participants with Adverse Events
Up to approximately 25 Months

An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a study intervention which does not necessarily have a causal relationship with the treatment. The investigator assesses the relationship of each event to the use of the study intervention.

Secondary Endpoints

Change from baseline on the Rasch transformed score of the FACE-Q Satisfaction with Cheeks module
Month 6
Percentage of Participants Achieving "Responder" Status based on Evaluating Investigator (EIs) assessments of Global Aesthetic Improvement in the treatment area using the Global Aesthetic Improvement Scale (GAIS)
