RHA® 4 With New Anesthetic - Nasolabial Folds

Completed · Not applicable

Conditions studied: Aging, Pain

In brief

This is a randomized, controlled, double-blinded, within-subject (split-face), multicenter, prospective study to investigate whether RHA® 4 with New Anesthetic Agent is non-inferior to RHA® 4 (with lidocaine) in terms of injection site pain felt by the subject during injection. At screening, the Treating Investigator (TI) evaluated subjects' NLF severity (using the Wrinkle Severity Rating Scale; WSRS) to confirm eligibility and to establish a pre-treatment score for assessing aesthetic improvement. At Visit 1, RHA® 4 With New Anesthetic Agent was administered in a random sequence (first or second injection) and side of the face (left or right) and RHA® 4 with lidocaine was administered to the other side. Study subjects and the TI injecting study devices were blinded. Immediately after injection of each side, subjects rated injection site pain experienced during injection using a 100 mm Visual Analog Scale (VAS). Injection site pain in each side of the face was also assessed at 15, 30, 45 and 60 minutes post-injection. 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 will be conducted. Subjects who present with an unresolved clinically significant device related AE at Visit 2 received the 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.

Who can join

Age: 22 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• 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.
• Moderate to severe bilateral nasolabial folds (grade 3 or 4 on the five-point WSRS).
• Nasolabial folds of the same WSRS grade on the left and right sides of the face.
• Able to follow study instructions and complete all required visits.
• 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.

You may not qualify if…

• Female subjects who are pregnant, breast-feeding, or of childbearing potential and not practicing reliable birth control.
• Known hypersensitivity or previous allergic reaction to any component of the study devices.
• Use of a prohibited treatment/procedure within time periods defined in the protocol
• Known sensitivity to local anesthetics of the amide type, history of multiple severe allergies, or history of anaphylactic shock.
• History of active chronic debilitating systemic disease that, in the opinion of the investigator, would make the subject a poor candidate in the study.
• History of connective tissue disease.
• Malignancy (excluding non-melanoma skin cancer) within the past 5 years.
• History of skin cancer in the treatment area.
• Clinically active disease or infection in the NLF area.
• Medical or psychiatric conditions that may increase the risk associated with study participation or may interfere with the interpretation of study results or compliance of the subject and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study.
• Clinically significant alcohol or drug abuse, or history of poor cooperation or unreliability.
• Exposure to any other investigational drug/device within 90 days of entering the study.
