Brief summary

This is a randomized, controlled, double-blinded, within-subject (split-face), multicenter, prospective study to investigate whether RHA® Redensity with new anesthetic agent is non-inferior to RHA® Redensity with lidocaine in terms of injection site pain felt by the subject during injection. At screening, the Treating Investigator (TI) evaluated subjects' perioral rhytid severity (using the Perioral Rhytid Severity Rating Scale; PR-SRS) to confirm eligibility and to establish a pre-treatment score for assessing aesthetic improvement. At Visit 1, RHA® Redensity with new anesthetic agent was administered in a random sequence (first or second injection) and side of the mouth (left or right) and RHA® Redensity with lidocaine was administered to the other side. Study subjects and the TI injecting study devices were blinded. Immediately after injection of an upper perioral quadrant, subjects rated the injection site pain experienced during injection using a 100 mm Visual Analog Scale (VAS). Injection site pain in each side of the mouth was also assessed at 15, 30, 45 and 60 minutes after injection of the upper quadrant. Safety evaluation consisted of AE assessments, a 30-day CTR (Common Treatment Response) diary and a follow-up call performed by the study site at 72 hours after injection. Subjects attended Visit 2 (30 days post-injection) where efficacy and safety assessments were conducted. Subjects who presented with an unresolved clinically significant device related AE at Visit 2 received a optional follow-up phone call no later than 30 days after Visit 2. If the clinically significant AE remained unresolved, the Investigator requested that the subject attended the optional in-clinic follow-up visit (i.e., Visit 3) within 5 working days. Follow-up of the clinically significant AE continued until the AE was resolved or the TI determines that additional follow-up was not necessary.

Interventions

A sterile, biodegradable, biocompatible, viscoelastic, clear, colorless, homogenized gel implant. It consists of cross-linked hyaluronic acid produced by fermentation of Streptococcus zooepidemicus, formulated to a concentration of 15 mg/g and 0.3% w/w of new anesthetic agent in a physiologic buffer.

Inclusion criteria

1. Outpatient, male or female of any race, 22 years of age or older. Female subjects of childbearing potential must have a negative UPT at Visit 1 and practice a reliable method of contraception throughout the study. 2. Moderate to severe bilateral perioral rhytids (grade 2 or 3 on PR-SRS). 3. Perioral rhytids of the same PR-SRS grade on the left and right sides of the mouth. 4. Able to follow study instructions and complete all required visits. 5. Sign the IRB-approved ICF, Photographic Release Form, the Authorization for Use and release of Health and Research Study Information (HIPAA) form, and if applicable the California Experimental Research Subject's Bill of Rights prior to any study-related procedures being performed.

History or presence of condition or feature that may confound the interpretation of the results in the perioral region, for example, tattoo, significant facial hair, acne scaring, prior surgery in the area, potential for active disease or infection flare up such as herpes simplex. 8. History of skin cancer in the treatment area. 9. Elective, clinically significant facial procedures that may confound the interpretation of the results in the perioral region (TI discretion), prior to study enrollment. 10.

Subject's Perception of Treatment Effectiveness as Per the FACE-Q (Perioral Rhytids Domain) Questionnaire.Visit 1 (Baseline) and Visit 2 (Day 30)The FACE-Q measures the experience and outcomes of aesthetic facial procedures from the patient's perspective. FACE-Q questionnaire is composed of 6 questions with a score linked to answers (1 being 'Not at all' and 4 being 'Extremely'). The subject will be instructed as follows: These questions ask about how you look right now. For each question, circle only one answer. With the area around your lips in mind, in the past week, how much have you been bothered by:, and will provide response. To calculate the FACE-Q, outcomes from all 6 questions were pooled, data were transformed so that higher scores reflected a superior outcome, and adapted to a scale of 100 units (i.e. lowest score = 0, highest score = 100).

The diary will be discussed during follow-up phone-call and visit. Subjects were instructed to complete the diary at approximately the same time each day (i.e., am or pm). The subject diary captured the following Common Treatment Responses (CTR) that occur following the injection of a dermal filler; specifically, redness, pain, tenderness, firmness, swelling, lumps/bumps, bruising, itching, discoloration, and other. The 30-day patient CTR diary included a detailed glossary describing all signs/symptoms listed in the diary; an option was provided to report other reactions if the subject experienced a sign/symptom that was not listed.

Subject's Perception of Treatment Effectiveness as Per the FACE-Q (Perioral Rhytids Domain) Questionnaire.

The FACE-Q measures the experience and outcomes of aesthetic facial procedures from the patient's perspective. FACE-Q questionnaire is composed of 6 questions with a score linked to answers (1 being 'Not at all' and 4 being 'Extremely'). The subject will be instructed as follows: These questions ask about how you look right now. For each question, circle only one answer. With the area around your lips in mind, in the past week, how much have you been bothered by:, and will provide response. To calculate the FACE-Q, outcomes from all 6 questions were pooled, data were transformed so that higher scores reflected a superior outcome, and adapted to a scale of 100 units (i.e. lowest score = 0, highest score = 100).
