Trial Outcomes & Findings for Randomized, Split-body, Single-blinded Clinical Trial of NB-UVB Treatment for Vitiligo (NCT NCT02506101)

NCT ID: NCT02506101

Last Updated: 2018-04-03

Results Overview

VASI scores of treated versus untreated symmetrical body sites.The percentage of vitiligo involvement is calculated in terms of hand units. One hand unit is approximately equivalent to 1% of the total body surface area. The degree of pigmentation is estimated to the nearest of one of the following percentages: 100% - complete depigmentation, no pigment is present; 90% - specks of pigment present; 75% - depigmented area exceeds the pigmented area; 50% - pigmented and depigmented areas are equal; 25% - pigmented area exceeds depigmented area; and 10% - only specks of depigmentation present. The VASI for each body region is determined by the product of the area of vitiligo in hand units and the extent of depigmentation within each hand unit measured patch. Total body VASI = S All body sites \[Hand Units\] ´ \[Residual depigmentation\].

Measure
Narrow-band Ultraviolet B Phototherapy
We will use the 3 Series PC \& SP Phototherapy Cabinet for treatment of vitiligo. narrow-band ultraviolet B phototherapy: There are two types of UVB: broad band and narrow band, with the major difference being that narrow band emits a smaller range of ultraviolet light, typically 311-312 nm. NB-UVB is a clinically indicated treatment for vitiligo lesions and treatments are usually administered in an outpatient setting 3 times a week.

PRIMARY outcome

Timeframe: 24 weeks

Population: No participants' data were analyzed, as no pertinent data for the outcome was obtained due to participants drop-out for personal reasons.

VASI scores of treated versus untreated symmetrical body sites.The percentage of vitiligo involvement is calculated in terms of hand units. One hand unit is approximately equivalent to 1% of the total body surface area. The degree of pigmentation is estimated to the nearest of one of the following percentages: 100% - complete depigmentation, no pigment is present; 90% - specks of pigment present; 75% - depigmented area exceeds the pigmented area; 50% - pigmented and depigmented areas are equal; 25% - pigmented area exceeds depigmented area; and 10% - only specks of depigmentation present. The VASI for each body region is determined by the product of the area of vitiligo in hand units and the extent of depigmentation within each hand unit measured patch. Total body VASI = S All body sites \[Hand Units\] ´ \[Residual depigmentation\].
