Safety and Effectiveness of ELLANSÉ®-S Dermal Filler in the Treatment of Nasolabial Folds

The study will be a prospective, randomized, multi-center, split-face, controlled, double-blind clinical trial to evaluate the safety and effectiveness of ELLANSÉ®-S for the treatment of NLFs. Subjects will be randomized to receive treatment (ELLANSÉ®-S) in one NLF and control (Radiesse®) in the contralateral NLF. A total of 126 subjects will be treated. The control and test articles will be supplied in sterile ready-to-use, pre-filled syringes. Initial treatment and any 4-week touch-up will be done consistent with initial randomization. Any retreatment(s) in either NLF will be with ELLANSÉ®-S. Subjects who meet Inclusion/Exclusion criteria will receive an initial treatment, an optional touch up at the 4-week visit, and may be eligible to receive retreatment at either 12 or 18 months after treatment (determined by when the fold has returned to baseline score, or the fold has lost at least 1 point on the Wrinkle Severity Rating Scale (WSRS) from optimal improvement). Retreatment to one side is allowed if only one side qualifies, but the other side may not be retreated at a later visit. If retreatment occurs, the subject may also be eligible to receive an optional touch up at the 4-week follow up visit. If a touch up occurs after the initial or retreatment injection, the subject will return for an additional safety visit 2 weeks after each injection. A week 4 safety visit will occur after retreatment touch-up. Primary effectiveness will be assessed at 6 months. All subjects will be followed for a minimum of 24 months after the initial treatment phase. After each injection, subjects will be contacted by telephone call/email after 72 hours and will return for a safety visit 2 weeks after treatment. At the week 4 visit, subjects will be assessed for a touch up. If a touch up is indicated as determined by the investigator, the investigator will use the same material as that used for initial treatment for the respective side. In addition, subjects will be seen at 6 weeks
