Multicenter Study to Evaluate the Safety and Efficacy of Revanesse® Ultra Retreatment

Study Overview
=================
Brief Summary
-----------------
To compare improvement with retreatment for all subjects undergoing correction of nasolabial folds (NLFs) in the initial SYM2014-02 study, who were retreated with Revanesse Ultra at Visit 6/Week 24 and to determine the safety of repeat injections of Revanesse Ultra. The retreatment phase was optional.

Detailed Description
-----------------
The subjects completing the initial phase of the SYM2014-02 study (NCT02987205) who had returned to baseline Wrinkle Severity Rating Scale (WSRS) score or as needed for optimal correction if WSRS scores had not returned to baseline, were offered the option for retreatment with Revanesse Ultra Visit 6/Week 24 (± 7 days) optional open-label retreatment with Revanesse Ultra for subjects who had returned to baseline Wrinkle Severity Rating Scale (WSRS) score or as needed for optimal correction if WSRS scores had not returned to baseline; End of Study for subjects not being retreated Visit 7/Week 28 (± 7 days) follow-up for retreated subjects Visit 8/Week 52 (± 7 days) End of Study for retreated subjects A telephone contact was performed at Week 40 (± 7 days) for retreated subjects to assess adverse events (AEs) and concomitant medications. This report presents the results for all subjects who received optional open-label retreatment with Revanesse Ultra at Visit 6/Week 24. This study was performed in compliance with Good Clinical Practice (GCP), including the archiving of essential documents. Number of Subjects (Planned and Analyzed): Seventy-one subjects received retreatment.

Official Title
-----------------
A Multicenter, Double-Blind, Randomized, Split-Face Study to Evaluate the Safety and Efficacy of Revanesse® Ultra (Retreatment)

Conditions
-----------------
Nasolabial Fold Correction

Intervention / Treatment
-----------------
* Device: Revanesse Ultra


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Subjects from the SYM2014-02 initial study who were: Men or women at least 22 years of age with two fully visible bilateral nasolabial folds each with a WSRS score of 3 or 4 (moderate or severe) that may have been corrected with an injectable dermal filler. Subjects were eligible for retreatment when WSRS scores had returned to baseline for either or both NLFs (retreatment group). If scores had not returned to baseline, subjects were also eligible to be injected for either one or both NLFs as needed to achieve optimal correction (optimal correction group).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the Wrinkle Severity Rating Scale (WSRS) With Subjects From Both the Retreatment and the Optimal Correction Groups - WSRS Scores at Visit 8/Week 52 | Change in the Wrinkle Severity Rating Scale (WSRS) With Subjects From Both the Retreatment and the Optimal Correction Groups Achieving Similar WSRS Scores at Visit 8/Week 52 - WSRS Score categories: 1. Absent - No visible fold; continuous skin line. 2. Mild - Shallow but visible fold with a slight indentation; minor facial feature; implant is expected to produce a slight improvement in appearance. 3. Moderate - Moderately deep folds; clear facial feature visible at normal appearance but not when stretched; excellent correction is expected from injectable implant. 4. Severe - Very long and deep folds; prominent facial feature; less than 2 mm visible when stretched; significant improvement is expected from injectable implant. 5. Extreme - Extremely deep and long folds, detrimental to facial appearance; 2 to 4 mm visible V-shaped fold when stretched; unlikely to have satisfactory correction with injectable implant alone. An increase in the WSRS score indicates a worsening of severity. | Visit 8/Week 52 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Retreatment Safety Assessed by the Incidence of Adverse Events (AEs), Which Were Defined, Recorded, Reported, and Evaluated, by Number and Severity | Assess safety concerns with retreatment of Revanesse Ultra for men or women at least 22 years of age with NLFs with a moderate or severe WSRS score at baseline who had previously received 1 or 2 treatments with Restylane or Revanesse Ultra, Adverse Events (AEs), which were defined, recorded, reported, and evaluated | Visit 6/Week 24, Visit 7/Week 28, Visit 8/Week 52 | 
| Patient Global Aesthetic Improvement (pGAI) Score | Subjects were evaluated on the Patient Global Aesthetic Improvement (pGAI) Patient Global Aesthetic Improvement (pGAI) Score: 1 = Worse, 2 = No change, 3 = Improved, 4 = Much improved, 5 = Very much improved | Visit 8/Week 52 |
