Trial Outcomes & Findings for Excimer Light Treatment for Idiopathic Guttate Hypomelanosis: A Pilot Study (NCT NCT01956435)
NCT ID: NCT01956435
Last Updated: 2017-12-02
Results Overview
Effectiveness will be graded by the blinded observer scal via photographic comparisons at the end of the study. Efficacy was assessed by improvement from baseline using the following scale: -1 = Worsening of IGH; 0 = No Improvement (IGH remained stable); 1 = Mild improvement of IGH (some re-pigmentation on \<50% IGH); 2 = Moderate improvement (some re-pigmentation on \>50% or full re-pigmentation on \<75% IGH); 3 = Full re-pigmentation on \>75% IGH.

PRIMARY outcome
Timeframe: 12 weeksPopulation: healthy adult patients with bilateral IGH lesions on lower extremities
Effectiveness will be graded by the blinded observer scal via photographic comparisons at the end of the study. Efficacy was assessed by improvement from baseline using the following scale: -1 = Worsening of IGH; 0 = No Improvement (IGH remained stable); 1 = Mild improvement of IGH (some re-pigmentation on \<50% IGH); 2 = Moderate improvement (some re-pigmentation on \>50% or full re-pigmentation on \<75% IGH); 3 = Full re-pigmentation on \>75% IGH.

SECONDARY outcome
Timeframe: 12 weeksPopulation: healthy adult patients with bilateral IGH lesions on lower extremities
Subject reported level of re-pigmentation for treated lesions was assessed by improvement from baseline using a scale from 1 - 4 with 1 being the least amount of re-pigmentation and 4 being the most re-pigmentation: 1 = Worsening of the light spots that were treated (the light spots seem to have gotten lighter or I have more light spots in the areas that were treated); 2 = No Improvement of the light spots (light spots have not changed since starting this study); 3 = Mild improvement of the light spots (there is some darkening of the light spots, but not in more than half of them); 4 = Moderate improvement (there is some darkening of the light spots in more than half of the light spots, but not more than 75% of them).
