Polymeric Microspheres vs Sculptra® in the Treatment of Moderate to Severe Nasolabial Folds

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participant whose age is ≥ 18 and ≤ 65 years old.

  • Participant is able to understand and comply with protocol requirements and instructions and likely to complete the study as planned.
  • Participant who has moderate to severe nasolabial folds on two sides of face, WAS Score ≥ 3. WAS Score is determined by investigator.

Treatment and study plan

PBF PLLA microsphere (injectable poly-L-lactic acid)

Device

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.

Sculptra®

Device

Sculptra®

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®

    Time frame: 26 weeks

    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

Secondary outcomes

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

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

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

  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®

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

    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

    Grade 1: No visible nasolabial fold; continuous skin line Grade 2: Shallow but visible nasolabial fold with a slight indentation; minor facial feature; the implant is expected to produce a slight improvement in appearance Grade 3: Moderately deep nasolabial folds; clear facial feature visible at normal appearance but not when stretched; excellent correction is expected with injectable implant Grade 4: Very long and deep nasolabial folds; prominent facial feature; 2mm visible fold when stretched; significant improvement is expected with injectable implant Grade 5: Extremely deep and long nasolabial folds, detrimental to facial appearance; 2-4mm visible V-shaped fold when stretched; unlikely to have satisfactory correction with injectable implant alone

  7. Number of subjects scored either 'Much Improved' or 'Improved' on GAIS evaluated by the Investigator for PLLA(PBF) versus Sculptra®
