Clinical Study for the Evaluation of the Safety and Effectiveness of Use of a Poly-L Lactic Acid Injectable Filler for the Aesthetic Treatment of Nasolabial Folds

Not Applicable

Completed

Conditions: Wrinkle

Interventions: Device: Gana V®
Device: Sculptra®

Registration Number: NCT05215054

Lead Sponsor: GCS Co., Ltd

Brief Summary: The purpose of this study is to assess the effectiveness and safety of Gana V, a Poly L-lactic acid filler for the aesthetic treatment of nasolabial folds, in comparison with Sculptra.

Detailed Description: A screening visit will allow to inform and preselect the participants.

On D0, baseline scoring, fringe projection acquisitions and photographs will be done before injection. Eligible participants will receive a first injection of the two products according to the randomization list. Immediately after injection, injector's treatment satisfaction will be collected. Investigator evaluator will collect Adverse Events (AEs) and Injection Site Reactions (ISRs) immediately after injection.

A month and a half after initial injection (M11/2), clinical scoring, fringe projection acquisitions and photographs will be done before touch-up (if applicable). Participant's treatment satisfaction and injector's treatment satisfaction (if applicable) will be collected. A touch-up injection will be made if necessary, according to injector and participant opinion. Investigator evaluator will collect AEs and ISRs before and after touch-up if applicable.

Three (M3), six (M6), nine (M9), twelve (M12), eighteen (M18) and twenty-four (M24) months after initial injection, clinical scoring, fringe projection acquisitions and photographs will be done. Participant's treatment satisfaction will be collected. Investigator evaluator will collect AEs and ISRs

Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Gana V versus Sculptra	Sculptra®	Participants will receive both Gana V and Sculptra: one in each nasolabial folds
Gana V versus Sculptra	Gana V®	Participants will receive both Gana V and Sculptra: one in each nasolabial folds

Primary Outcome Measures

Name	Time	Method
Change From Baseline in the Nasolabial Folds Severity Score on the Wrinkle Severity Rating Scale (WSRS) 6 Months After Treatment	Baseline and Month 6	The Wrinkle Severity Rating Scale is a scale for measurement of the nasolabial folds wrinkles severity. The scale ranges from Grade 1 (absent-better outcome) to Grade 5 (extreme-worse outcome) Change of grades was calculated as the value at 6 months minus the value at baseline. To observe an improvement of the nasolabial folds wrinkles, a decrease of the mean score was expected.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in the Nasolabial Folds Severity Score on the Wrinkle Severity Rating Scale (WSRS)	Baseline, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	The Wrinkle Severity Rating Scale is a scale for measurement of the nasolabial folds wrinkles severity. The scale ranges from Grade 1 (absent-better outcome) to Grade 5 (extreme-worse outcome) Change of grades was calculated as the value at month X minus the value at baseline. To observe an improvement of the nasolabial folds wrinkles, a decrease of the mean score was expected.
WSRS Responders Rate	Baseline, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	The Wrinkle Severity Rating Scale is a scale for measurement of the nasolabial folds wrinkles severity. The scale ranges from Grade 1 (absent-better outcome) to Grade 5 (extreme-worse outcome) Responders rate = percentage of participants with an improvement of at least one grade in WSRS compared to baseline score. An improvement represents a decrease in WSRS (from grade 5 to grade 4 for instance)
Global Aesthetic Improvement Scale (GAIS) Responder Rate	Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	Percentage of participants with an improvement on GAIS. A responder is defined as a subject having "Improved", "Much improved" or "Very much improved" score according to GAIS.
Change From Baseline in Nasolabial Folds Average Depth (mm)	Baseline, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	The average depth of the nasolabial folds wrinkles was calculated using a fringe projection system. An increase of the mean value means a positive outcome. Change was calculated as the value at each follow-up visit minus the value at baseline
Change From Baseline in Nasolabial Folds Volume	Baseline, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	The volume of the nasolabial folds wrinkles was calculated using a fringe projection system. A decrease of the volume means a positive outcome.
Proportion of Satisfied Participants	Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	Percentage of participants with positive answers to an internal questionnaire
Injector Satisfaction	After initial injection (Day 0) and touch-up if applicable (Month 1^1/2)	Percentage of participants
Collection of Injection Site Reactions	Day 0, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24	Proportion of subjects presenting at least one ISR of any severity
Collection of Adverse Events	Day 0 to Month 24	Number of Adverse Events (AEs) Number of Adverse Device Effects (ADEs) Proportion of subjects with at least one AE Proportion of subject with at least one ADE
