Brief Summary

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 3, 6, 9, 12, 18, and 24 months (from the end of the initial treatment phase). Subjects receiving a retreatment (at 12 or 18 months after treatment) will return for additional safety visits at 2 weeks and 3 and 6 months after this retreatment (the 6 month coincides with regularly scheduled visit). Subjects will have the option of a retreatment touch up injection at 4 weeks after retreatment, and if they do will have another call at 72hrs and a week 2 safety visit. The validated Wrinkle Severity Rating Scale will be used for assessment of the primary effectiveness endpoint (1). Assessment of the secondary effectiveness endpoints will include use of WSRS, the Global Aesthetic Improvement Scale (GAIS), VAS pain assessment, the validated FACE-Q Appraisal of Nasolabial Folds Questionnaire, the FACE-Q Satisfaction with Treatment Outcome Scale and the FACE-Q Age Appraisal VAS. The study will last approximately 30 months. All subjects will be recruited within approximately 6 months after the recruitment of the first subject and followed for a minimum of 24 months after the initial treatment visit. Subjects receiving a retreatment (at 12 or 18 months) will receive a telephone call/email 72 hours after retreatment and they will return for an additional safety visit 2 weeks after retreatment. Subjects may receive a retreatment touch up at 4 weeks after retreatment, and if touched up, will have safety visits at 2 and 4 weeks. All retreated subjects will also be asked to attend month 3 and month 6 safety visits. The 6-month safety visit will correspond with the next study visit (e.g., 18 month or 24-month visit depending on when they are reinjected) 126 male and female subjects will be enrolled. This enrollment number accounts for a 20% attrition rate, to ensure an adequate safety population for long-term follow-up, and a Per Protocol Set (PPS) of at least 101 NLFs per treatment arm. At least 20% of treated subjects will have Fitzpatrick Skin Types IV, V, and VI. Of these, at least, 10% will be Type IV, 5% Type V and 5% Type VI. The investigative sites will be encouraged to enroll both male and female subjects. In addition, up to 2 non-randomized, non-split-face run-in subjects will be treated with ELLANSÉ®-S by each investigator to allow the investigator to become familiar with injection characteristics. This run-in cohort will be required to meet all study inclusion/exclusion criteria and will be followed in the same manner as the non-run-in cohort. Up to seven US sites will participate.

Outcome Measures

Primary Outcomes (1)

• Mean Change in NLF WSRS score from baseline at 6 months by a live, masked reviewer

  The primary effectiveness endpoint uses the 6-month and baseline Wrinkle Severity Rating Scale (WSRS) scores as determined by a live, masked reviewer. The change from baseline on the WSRS at 6 months of NLFs in the ELLANSÉ®-S treatment arm will be compared to that of NLFs in the Radiesse® control arm. The statistical objective is to demonstrate non-inferiority of WSRS improvement in the NLF indication of ELLANSÉ®-S to Radiesse®. Note: the WSRS provides 5 scoring options from 1 Absent to 5 Extreme. A lower score is a better clinical outcome.

  6 months

Secondary Outcomes (16)

• Difference in mean change from baseline on the Wrinkle Severity Rating Scale (WSRS) at 12 months as rated by a live, masked reviewer

  12 months

• Global Aesthetic Improvement Scale (GAIS) response rate at 6 months as rated by the live, masked reviewer

  6 months

• Difference in mean change in total score on the FACE-Q Appraisal of Nasolabial Folds Questionnaire at 6 months.

• Difference in mean change in total score on the FACE-Q Appraisal of Nasolabial Folds Questionnaire at 12 months

• Difference in mean change from baseline on the Wrinkle Severity Rating Scale (WSRS) at 18 months as rated by a live, masked reviewer.

Other Outcomes (1)

Eligibility Criteria

You may qualify if:

• Subject is male or female aged at least 22 years.

• Subject is willing to provide written informed consent for their participation in the study.
• Subject has best corrected visual acuity of 20/40 or better (in each eye), and have normal confrontational visual fields, and normal extraocular motility.

You may not qualify if:

• Subjects having any of the following criteria, either at screening or at baseline, will not be included in the study:
• Subject is a female of childbearing potential (e.g., not postmenopausal for at least one year or has not had a hysterectomy or tubal ligation) not using medically effective birth control (e.g., hormonal methods in use at least 30 days prior to injection or barrier methods such as condom and spermicide in use at least 14 days prior to injection) or is pregnant, lactating, or plans to become pregnant during the study.

• Subject has a serious or progressive disease, which, in the investigator's judgment, puts the subject at undue risk (e.g., uncontrolled diabetes, autoimmune disease, cardiac pathologies).
• Subject has an acute inflammatory process or infection, or history of chronic or recurrent infection or inflammation with the potential to interfere with the study results or increase the risk of adverse events.
• Subject has a disorder that may impact wound healing such as connective tissue or immunosuppressive disorder.
• Subject has a history of precancerous lesions/skin malignancies.
• Subject has had an active skin disease within the past 6 months.
• Subject has scars, infection, rosacea, herpes, acne, blotches or other pathology in the NLFs that in the Investigator's opinion will affect evaluation or treatment.
