Clinical Trial Summary

This randomized, single-center, double-blinded, split-face, controlled clinical trial was conducted to investigate the tolerability, safety, and efficacy of a post-procedure cream when used immediately after fractional ablative CO2 laser treatment and for 14 days post-procedure with three times daily application in healthy female subjects aged 35 to 65 with moderate to severe global facial overall photodamage (score of 4 to 9 out of the 10-point Modified Griffiths' scale). Furthermore, this clinical trial compared the active post-procedure cream to a comparator anhydrous formulation often paired with skin rejuvenation procedures. This is a cosmetic study with a FDA-regulated device.

A total of 22 healthy female subjects completed the study.

Description:

This randomized, single-center, double-blinded, split-face, controlled clinical trial was conducted to investigate the tolerability, safety, and efficacy of a post-procedure cream when used immediately after fractional ablative CO2 laser treatment and for 14 days post-procedure with three times daily application in healthy female subjects aged 35 to 65 with moderate to severe global facial overall photodamage (score of 4 to 9 out of the 10-point Modified Griffiths' scale). The ability of the post-procedure cream to soothe skin and improve patient downtime post-procedure was investigated by evaluating tolerability parameters (erythema, edema, dryness, burning, itching, stinging) and pain over the course of the study. Furthermore, this clinical trial compared the active post-procedure cream to a comparator anhydrous formulation often paired with skin rejuvenation procedures.

A 14-day washout period was required of all subjects prior to CO2 laser treatment. Tolerability (investigator: erythema, edema, dryness; subject: burning, itching, stinging) and safety were assessed through grading at screening, pre-procedure, post-procedure, post-procedure/post-product application, and days 1, 3, 5, 7, and 14 post-procedure. Pain evaluations were completed by subjects using the 11-point Wong Baker Faces® Pain Rating scale post-procedure, post-procedure/post-product application, and days 1, 3, 5, 7, and 14 post-procedure.

In addition, efficacy evaluation using the Modified Griffiths' scale was performed at screening, pre-procedure, and days 1, 3, 5, 7, and 14 post-procedure. Self-assessment questionnaires were completed by subjects post-procedure/post-product application and days 1, 3, and 14 post-procedure. Clinical photography was completed at all timepoints (screening to day 14 post-procedure).

A total of 22 subjects completed study participation.

Intervention

Procedure:
• Fractional Ablative CO2 Laser
A fractional ablative DEKA SmartXide Tetra CO2 laser treatment was performed after a 14-day washout period. Subjects were numbed for 1 hour prior to procedure with topical numbing cream (lidocaine 23%, tetracaine 7%). The global face was treated with a single pass. Treatment parameters include power 20 W, spacing 500 um (13% density), Dwell time 1200 us DEKA pulse mode, spray mode on.

Other:
• Facial Cleanser
Facial cleanser was to be used by subjects twice daily during the 14-day washout period and three times daily during the 14-day post-procedure timeline.
• Facial Moisturizer
A bland facial moisturizer was to be used by subjects twice daily during the 14-day washout period and three times daily between day 3 and 14 post-procedure. Two pumps were to be applied to the face (avoiding the upper eyelid) after applying the active and comparator.
• Sunscreen
During the 14-day washout period, a bland sunscreen was to be used by subjects in the morning after cleansing and facial moisturizer application with reapplications as needed throughout the day per FDA recommendations. For days 3-14 post-procedure, the bland sunscreen was to be used daily by subjects in the morning and afternoon after cleansing, split-face application of the active post-procedure cream and comparator anhydrous formulation, and facial moisturizer application.
• Basic Ointment
The basic ointment was used only on the comparator side for three days (72 hours) post-procedure. This was a requirement of the comparator anhydrous formulation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Investigator Tolerability	The primary tolerability endpoint will be Investigator Tolerability Assessment of erythema, edema, and dryness. A change in score or lack of significant change post product application, Day 1 (24 hours), Day 3, Day 5, Day 7, and Day 14 in comparison to baseline (immediately post-procedure) indicates tolerability / safety of the test material.; A four-point scale will be used with a lower score indicating a better outcome: 0 = None; = Mild; = Moderate; = Severe	14 days
Primary	Incidence of Adverse Events	The primary safety endpoint will be determined by the incidence and severity of adverse events in healthy subjects, including immediately post-procedure and throughout the length of the study.	14-days
Primary	Subject Tolerability	The subject tolerability endpoint will be Subject Tolerability Assessment of burning, itching, and stinging. A change in score or lack of significant change post product application, Day 1 (24 hours), Day 3, Day 5, Day 7, and Day 14 in comparison to baseline (immediately post-procedure) indicates tolerability / safety of the test material.; A four-point scale will be used with a lower score indicating a better outcome: 0 = None; = Mild; = Moderate; = Severe	14 days
Secondary	Self-Assessment Questionnaire	A change in response values at Day 1 (24 hours), Day 3, and Day 14 compared to post-procedure/post-product application response values indicates an improvement. Baseline responses will be set to post-procedure/post-product application. Subjects are asked to rate based on a scoring system of the following: from 5 (completely agree) to 1 (completely disagree). The best outcome is to Completely Agree with the statement / question being asked.	14 days
