Clinical Trial Summary

Randomized, double-blind, placebo-controlled, research pilot study. 30 subjects aged 22-55 years old of all skin types will be asked to sign an informed consent form prior to any study procedures. Subjects must have at least 1 but up to 3 acne scars ≥3 mm or ≤ 10 mm located on the cheeks or forehead. Subjects will receive one treatment (Restylane® Silk or Placebo) in each scar at day 0, and Month 1 (2 total treatments per scar during the study). Subjects will be asked to come to 10 visits: Screening visit (up to 35 days prior to Baseline), Baseline (Day 0), Day 7, Day 14, Month 1, Month 2, Month 3, Month 4, Month 5, and Month 6 (study exit visit). The treatment area will be evaluated at each visit by the unblinded investigator regarding erythema, bruising, inflammation, itching, stinging/burning, brightness, fullness, smoothness, and clarity. Safety and adverse events will be captured at each visit only by the unblinded investigator.

Description:

Randomized, double-blind, placebo-controlled, research pilot study. 30 subjects aged 22-55 years old of all skin types will be asked to sign an informed consent form prior to any study procedures. Subjects must have at least 1 but up to 3 acne scars ≥3 mm or ≤ 10 mm located on the cheeks or forehead. Subjects will receive one treatment (Restylane® Silk or Placebo) in each scar at day 0, and Month 1 (2 total treatments per scar during the study). Subjects will be asked to come to 10 visits: Screening visit (up to 35 days prior to Baseline), Baseline (Day 0), Day 7, Day 14, Month 1, Month 2, Month 3, Month 4, Month 5, and Month 6 (study exit visit). The blinded investigators will evaluate the target scar using the Acne Scar Rating Scale (ASRS), rate the target acne scar regarding treatment effect on a -5 ("Markedly worse"), to 0 ("Neutral Improvement"), to 5 (Markedly Improved (Clear or nearly clear)) point scale, and evaluate the skin quality (regarding brightness, fullness, smoothness, and clarity). Subjects will give the acne scar a score on the subject VAS acne scar satisfaction scale marking between 0 ("Not satisfied with Acne Scar at Day 0") and 10 ("Extremely Satisfied with Acne Scar at Day 0"). The treatment area will be evaluated at each visit by the unblinded investigator regarding erythema, bruising, inflammation, itching, stinging/burning, brightness, fullness, smoothness, and clarity. The subject will have their vital signs taken, complete a symptom diary (only if the subject experiences side effects or adverse events), complete a DLQI, and have photos (VECTRA and 2D digital photographs) taken of the treatment area. Efficacy measures will only be completed by the blinded investigator. Safety and adverse events will be captured at each visit only by the unblinded investigator.

Exclusion Criteria:

1. Subjects with active cystic acne at screening (> 2 nodules or any cysts present at Baseline).

2. Use of antibiotics 2-weeks prior to screening.

3. Use of retinoids 2-weeks prior to screening.

4. Use of salicylic acid or benzoyl peroxide 7 days prior to screening.

10. Acne scars that are considered post-inflammatory erythematous, post-inflammatory hyperpigmentation, varicella (chicken pox) scars, or perifollicular elastolysis will not be allowed to be identified as the target acne scars. These types of scars are still allowed to be present but cannot be selected.

11. Acne scars that are located in the glabella and temple regions. Acne scars located in these regions will not be allowed to be selected as a target or additional acne scar. As well, scars located in these areas will not be allowed to be treated during the study. Subjects are allowed to have acne scars located in these areas but cannot have them selected for evaluation or treated during the study.

12. Laser or light (red and blue) treatments for acne 3 months prior to screening.

13. Resurfacing procedures (CO2 , Erbium, Fraxel, etc.) performed 6 months prior to screening.

14. Any chemical peels in the last 30 days prior to screening.

19. History of abuse with the use of alcohol or drugs.

20. Participation in a clinical trial or use of an investigational product in the past 30 days.
