Study summary

This is a single-dose, randomized, double-blind, active-controlled, split-face, multiple centers, non-inferiority study. Approximately 50 nasolabial fold subjects will be enrolled. Each enrolled subject will be randomized equally into one of the following groups:

  1. Group 1: right face will be injected with PBF PLLA microsphere, and left face with Sculptra®
  2. Group 2: right face will be injected with Sculptra® and left face with PBF PLLA microsphere Subjects will be administrated on Visit 1 by applying PBF PLLA microsphere on one side of face and Sculptra® on the other.

Interventions

  • DevicePBF PLLA microsphere (injectable poly-L-lactic acid)

    Poly-L-lactic acid (PLLA) is a collagen stimulator, helps restore the deep, underlying structure of the skin to diminish facial wrinkles. PLLA microparticles are absorbable for human body, and it works with human body within the deep dermis to help revitalize collagen production and help restore human skin's inner structure and volume. PLLA can rebuilt collagen strands begin gradually helping to restore facial volume and the look of fullness to wrinkles and folds.

What researchers measure

Primary outcomes

  1. Delta of the WAS score between the Baseline and 26 weeks after treatment assessed by the Independent Evaluators of PLLA(PBF) versus Sculptra®

    Wrinkle Assessment Scale (WAS): 0 No wrinkles; 1 Just perceptible wrinkle; 2 Shallow wrinkles; 3 Moderately deep wrinkle; 4 deep wrinkle, well-defined edges; 5 Very deep wrinkle, redundant fold

    Time frame: 26 weeks

Secondary outcomes

  1. Overall operation time during subcutaneous injection of PLLA(PBF) versus Sculptra®

    To compare the operational smoothness for physicians between the two medical devices

    Time frame: First week from the Start of administration to the end of administration

  2. Delta of the WAS score assessed by the Investigator between each follow-up visit (13th, 26th, 39th and 52nd week post-administration) and the Baseline of PLLA(PBF) versus Sculptra®

    Wrinkle Assessment Scale (WAS): 0 No wrinkles; 1 Just perceptible wrinkle; 2 Shallow wrinkles; 3 Moderately deep wrinkle; 4 deep wrinkle, well-defined edges; 5 Very deep wrinkle, redundant fold

    Time frame: 13th, 26th, 39th and 52nd week post-administration
