A Study to Assess Adverse Events and Change in Disease Activity of HArmonyCa Lidocaine Injectable Gel for Mid Face Soft Tissue Augmentation in Adult Participants

The cumulative effect of aging and environmental exposures (ie, ultraviolet, infrared, and visible light radiation and pollution) leads to wrinkles, discoloration, laxity, and roughness of sun exposed skin. The rapid restoration of soft tissue augmentation is commonly achieved by the use of dermal fillers. HArmonyCa Lidocaine injectable gel is a dermal filler intended for facial soft tissue augmentation. The purpose of this study is to assess adverse events and effectiveness of HArmonyCa Lidocaine injectable gel in adults seeking mid face soft tissue augmentation. HArmonyCa Lidocaine Injectable Gel is an investigational device being developed for soft tissue augmentation in the mid face. Participants are placed in 1 of 2 groups, called treatment arms. There is a 1 in 3 chance that participants will be assigned to the control group. Around 160 adult participants seeking soft tissue augmentation will be enrolled in the study at approximately 15 sites worldwide. Participants in the treatment group will receive HArmonyCa Lidocaine injectable gel at Day 1 and followed for up to 25 Months. Participants will have the opportunity to receive optional touch-up and optional repeat treatment of HArmonyCa Lidocaine injectable gel during the follow-up duration period. Participants in the control group are followed for 3 months and then can opt to receive HArmonyCa Lidocaine Injectable Gel at the end of month 3. The control group will participate in the study for up to 25 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
