Sculptra for Correction of Midface Volume Deficit and/or Midface Contour Deficiency

A Randomized, Multi-center, Evaluator-blinded, No-treatment Controlled Study to Evaluate the Effectiveness and Safety of Sculptra for Correction of Midface Volume Deficit and/or Midface Contour Deficiency

This is a randomized, evaluator-blinded, no-treatment controlled study in participants with Midface Volume Deficit and/or Midface Contour Deficiency.

For Group A, after screening, eligible participants will be treated from day 1 and followed up for 24 months. The purpose of Group A was to confirm investigator's use of correct injection technique.

For Group B, the study includes two phases as follows:

Main study phase: It is randomized, evaluator-blinded and no-treatment controlled. After screening, all eligible participants will be randomized either to the Treatment Group or the Control Group in a 2:1 ratio. All the participants will be followed up for 12 months.

Extension study phase: After the main study phase, the Treatment Group will be followed up for additional 12 months.

Each subject assigned to Group A and Treatment Group will receive up to 4 injection sessions with 5(±1) weeks intervals.

Participants assigned to the Control Group will not receive treatment during the study.

Inclusion Criteria:

1. Signed and dated informed consent to participate in the study.
2. Men or women aged 18 years of age or older of Chinese origin.
3. Participants seeking augmentation therapy for the midface.
4. MMVS score of 2, 3 or 4 on each side of the face as assessed by the blinded evaluator.

Exclusion Criteria:

1. Known/previous allergy or hypersensitivity to any of the constituents of the product.

Other condition preventing the subject from entering the study in the Investigator's opinion, e.g. participants not likely to avoid other facial cosmetic treatments, participants anticipated to be unreliable, unavailable or incapable of understanding the study assessments or having unrealistic expectations of the treatment result.
