Pilot Evaluation of the Lutronic PicoPlus System for the Treatment of Benign Pigmented Lesions of the Hands

Not Applicable

Active, not recruiting

• Conditions: Benign Pigmented Lesions

• Registration Number: NCT04208100
• Lead Sponsor: LUTRONIC Corporation

Brief Summary

Prospective, multi-site, non-randomized study of up to 40 treated subjects; subjects enrolled may be greater than subjects treated.

Detailed Description

Subjects will be enrolled to ensure a minimum number of subjects by skin type participate in the study as follows: FST I-II, at least 5 subjects; FST III, at least 10 subjects; FST IV, at least 5 subjects. Additionally, up to 20 training subjects will be enrolled that will be excluded from efficacy analysis, but will be included in safety analysis.

Standardized baseline and follow-up images will be taken using the sites' preferred camera system. No pre-treatment medication prior to study treatment.

Phase I: Study subjects will receive up to three treatments with the PicoPlus with the 595nm on one hand and the 660nm on the other hand. Subjects will receive the same wavelength for all treatments on each specific hand; treatments will alternate by subjects between the left side getting treated with the 595nm and the right side getting treated with the 660nm depending on enrollment. Treatments will be 30+7 days apart up to three treatments until desired clearance has been achieved.

Phase II: Up to 2 balancing treatments may be done if needed based on the investigator's discretion to achieve equal clearance on each hand utilizing the wavelength of the investigator's choice. Phase II will not be considered for efficacy endpoints.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Pigmentary Clearance	30 days	Percentage of pigmentary clearance by each wavelength in standard photographs from the 30-day visit post the last treatment in Phase I of the study using a score of 0-4, representing poor 0-24%, fair 25-49%, good 50-74%, excellent 75-95%, and complete 95%+ improvement was given at the day 30 follow-up visit post the last treatment as determined by three blinded physician evaluators comparing the baseline vs 30-day follow-up visit photographs.

Secondary Outcome Measures

Name	Time	Method
Clinician Global Aesthetic Scale	30 days	The Principal Investigator, sub-investigator or qualified clinician delegated by the principal investigator, will complete a Clinician Global Aesthetic Improvement Scale assessing overall aesthetic improvement by wavelength at the 30-day visit following the last treatment visit for Phase I of the study. Scale ranging 1-Very Much Improved and 5-Worse.
Subject Global Aesthetic Scale	30 days	2. The subject will complete a SGAIS assessing overall aesthetic improvement by wavelength at the 30-day visit following the last treatment visit for Phase I of the study. Scale Ranging 1-Very Much Improved and 5-Worse.
