Clinical trials

This is a prospective, multi-center, randomized, no-treatment controlled, evaluator-blinded clinical investigation to identify whether TEOSYAL RHA® 1 is superior to no treatment for the correction of moderate to severe tissue volume deficiencies in the infraorbital region in Chinese adults. Eligible subjects will be enrolled and randomized either to the treatment group or control group in a 3:1 ratio on Day 0. Each subject assigned to the treatment group will receive TEOSYAL RHA® 1 in both Infraorbital Hollows (IOH), whereas subjects assigned to the control group will not receive any treatment. The subjects in the treatment group will be treated with RHA1 for the treatment of moderate to severe tissue volume deficiencies in the infraorbital region on Day 0. All treated subjects will return to the site at 2, 4, 12, 24, 36, and 52 weeks after the last treatment for effectiveness and safety assessments. Each treated subjects will receive a safety phone call 3 days after the initial treatment at baseline, and after the touch-up treatment, if any. Their participation in the trial ends after the completion of the follow up period. All non treated subjects (control group) will return to the site at 2, 4, and 12 weeks after randomization for effectiveness and safety assessments. Their participation in the investigation ends after the effectiveness and safety assessments at 12 weeks after randomization.
