NCT ID: NCT00703846

Last Updated: 2017-01-30

Results Overview

An AE is any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, which does not necessarily have a causal relationship with the treatment. For a list of all adverse events occurring at or above a frequency threshold of 5% during the course of the study, see the table entitled "Other (Non-Serious) Adverse Events."

Number of Participants With Any Adverse Event (AE)
282 participants

SECONDARY outcome

Timeframe: Baseline and Weeks 4, 8, 16, 26, 39, and 52 (or early termination)

Population: Safety Analysis Set. Participants withdrew from the study as the study progressed, and data were missing for some participants. There were no imputation methods used for missing data for any analysis.

Mean change from baseline was calculated as the Week 4, 8, 16, 26, 39, and 52 (or early termination) value minus the baseline value. The grading scale for erythema ranges from 0 to 4; 0=Normal skin without erythema; may have residual hyper/hypopigmentation; 1=Faint erythema; may have residual hyper/hypopigmentation; 2=Light red erythema; may have residual hyper/hypopigmentation; 3=Moderate red coloration; 4=Dusky to deep red coloration. Erythema was defined as redness of the skin caused by increased blood circulation in the capillaries found in the deeper layers of the skin.

Mean change from baseline in skin assessments for scaling was calculated as the Week 4, 8, 16, 26, 39, and 52 (or Early Termination) value minus the baseline value. The grading scale for scaling ranges from 0 to 4; 0=Normal skin with rare fine scale; 1=Minimal: occasional fine scales over less than 10% of the lesions; 2=Mild: fine scales predominate; 3=Moderate: coarse scales predominate; 4=Severe: thick tenacious scales predominate. Scaling of skin is the loss of the outer layer of the epidermis in large, scale-like flakes.

Mean change from baseline was calculated as the Week 4, 8, 16, 26, 39, and 52 (or Early Termination) value minus the baseline value. The grading scale for pruritis ranges from 0 to 4; 0=No itching; 1=Minimal: rarely aware of itching; 2=Mild: only aware of itching at times; only present when relaxing; not present when focused on other activities; 3=Moderate: often aware of itching; annoying; sometimes disturbs sleep and daytime activities; 4=Severe: constant itching; distressing; frequent sleep disturbance; interferes with activities. Pruritus is defined as an itching/scratching sensation.

This seborrhoeic dermatitis-specific ISGA scale (range=0-4) is used to assess skin condition severity without considering changes over time ("static"). 0=clear, except for minor residual discoloration; 1-4=majority of lesions have average scaling/erythema scores of 1-4, respectively. 1=almost clear, occasional fine scale, faint erythema/barely perceptible plaque thickness; 2= mild, fine scale with light coloration/mild plaque elevation; 3=moderate, coarse scale with moderate red coloration/moderate plaque thickness; 4=severe, thick tenacious scale with deep coloration/severe plaque thickness.

SECONDARY outcome

Timeframe: From baseline through 52 weeks

Population: Safety Analysis Set

The median number of flares for all participants was calculated based on data self-reported in diaries that participants kept during the study. A flare is defined as a clinical diagnosis and presentation of seborrheic dermatitis that shows as an erythematous, thin, scaly patch with a greasy sandpaper texture that varies depending on disease severity. Flares are commonly seen on the scalp, nasal folds, eyebrows, glabella, upper eyelids, retroauricular/external ear canal, and midchest areas.

The median number of flares for all participants was calculated based on data self-reported in diaries that participants kept during the study.

Skindex-29 is a 3-component (symptomatic, emotional, and functional) self-administered questionnaire (comprised of 30 questions) used to comprehensively measure the complex effects of skin diseases on a participant's quality of life. Participants were asked to answer questions based on a 5-point scale concerning their feelings over the past 4 weeks about the skin condition that has bothered them the most: 1, never; 2, rarely; 3, sometimes; 4, often; 5, all the time. The Global Score is the sum of the 30 question scores; total score ranges from 30 to 150.
