To Evaluate the Safety and Efficacy of Poly-L-lactic Acid Implants for the Correction of Nasolabial Folds
Taiwan121 participantsStarted 2026-02-01
Plain-language summary
The goal of this clinical trial is to evaluate the safety and effectiveness of a poly-L-lactic acid (PLLA) dermal implant for the correction of nasolabial folds. The study also aims to determine whether the investigational product (FUYANMEI Poly-L-Lactic Acid) is non-inferior to the control product (Sculptra).
The main questions it aims to answer are:
* Is the effectiveness rate based on the Wrinkle Severity Rating Scale (WSRS) at 6 months after injection for the investigational group non-inferior to that of the control group?
* How does the investigational product perform in terms of global aesthetic improvement as assessed by blinded evaluators and by subjects?
* What is the safety profile of the investigational product, including the incidence, severity, and relatedness of adverse events (AEs), serious adverse events (SAEs), and device deficiencies (DDs)?
Researchers will compare the investigational PLLA implant to an approved PLLA implant using a prospective, randomized, evaluator- and subject-blinded, single-center, split-face controlled study design. Approximately 121 eligible participants will be enrolled.
Participants will:
* Receive treatment with the investigational product and the control product according to the split-face design
* Be followed for 24 months after injection
* Return to the clinic at 1, 3, 6, 12, 18, and 24 months post-injection for follow-up visits
* Undergo blinded evaluator assessments of WSRS and Global Aesthetic Improvement Scale (GAIS)
* Complete subject self-assessments of GAIS and treatment satisfaction
* Be monitored throughout the study for adverse events, serious adverse events, and medical device deficiencies
