Brief summary

This study is intended to evaluate the efficacy and safety of a new diode fractional laser for skin resurfacing and treatment of pigmented lesions.

Detailed description

This study is a prospective, open-label, clinical trial to study the effects of the nonablative, fractional diode laser for skin resurfacing. Up to 60 eligible participants will be enrolled at up to three (3) sites. Participants will receive up to 4 treatments to the face, and other off-face locations may be treated. Participants will complete follow-up visits for clinical evaluation and photography at 1 and 3 months after the final treatment.

Interventions

DEVICENonablative Fractional Diode Laser

The FRAX 1940 is a fractional 1940 nm solid-state diode laser that delivers linear arrays of microbeams to create nonablative microscopic treatment zones (MTZs) in the skin.

Outcome results

Primary

Pigmented Lesion Improvement by Blinded Evaluation

The primary efficacy endpoint was defined as improvement in the clearance of pigmented lesions, as assessed by three (3) blinded evaluators comparing photographs taken at Baseline/Pre-treatment and at the 1-month follow-up (post final treatment)

Time frame: 1 month follow-up post treatment series, where treatment could last up to 10 weeks from baseline

Population: Data from FRX19004 study was combined with FRX19005 study (NCT04202419) for ad-hoc primary efficacy analysis via blinded evaluation. Both trials assessed the 'treatment of pigmented lesions' and are directly comparable due to equivalence of patient populations and efficacy endpoints, therefore, the exact same analyses were performed. The treated area was considered a success if at least 2 of the 3 reviewers correctly identified the post-treatment photograph (i.e. left or right side).
