RHA® Redensity With New Anesthetic Agent Perioral Rhytids (PAS)

Sponsor: Teoxane SA

View on ClinicalTrials.gov

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 Principal Investigator (PI) 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 PI 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 effectiveness 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.

DEVICE

RHA® Redensity with new anesthetic agent

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.

DEVICE

RHA® Redensity with lidocaine

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. Perioral rhytids of the same PR-SRS grade on the left and right sides of the mouth. 3. Able to follow study instructions and complete all required visits. 4. 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. Exclusion Criteria: 1. Female subjects who are pregnant, breast-feeding, or of childbearing potential and not practicing reliable birth control. 2. Known hypersensitivity or previous allergic reaction to any component of the study devices. 3. Known sensitivity to local anesthetics of the amide type, history of multiple severe allergies, or history of anaphylactic shock. 4. Clinically significant active skin disease or infection in the perioral area within 6 months prior to study entry (TI discretion). 5. History of active chronic debilitating systemic disease that, in the opinion of the investigator, would make the subject a poor candidate in the study. 6. Malignancy (excluding non-melanoma skin cancer) within the past 5 years. 7. 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. Clinically active disease or infection in the perioral area or mouth (e.g., dental abscess). 11. Clinically significant alcohol or drug abuse, or history of poor cooperation or unreliability.
