Trial Outcomes & Findings for Efficacy and Safety of AN2898 and AN2728 Topical Ointments to Treat Mild-to-Moderate Atopic Dermatitis (NCT NCT01301508)

NCT ID: NCT01301508

Last Updated: 2019-02-22

Results Overview

ADSI score was used to measure the severity of participant's atopic dermatitis (AD) affected lesion. It evaluated 5 signs of AD (erythema, pruritus, exudation, excoriation and lichenification) in each lesion. Each sign was rated by investigator on a scale of 0 (none) to 3 (severe), where higher score indicated more severe condition. Total ADSI score for each lesion was sum of scores of the 5 signs and ranged from 0 (none) to 15 (most severe), where higher score indicated more severe condition.

Measure
AN2898 Ointment, 1% + Ointment Vehicle
Participants with mild to moderate atopic dermatitis (AD) applied AN2898 ointment, 1 percent (%) to one target lesion (active lesion), topically twice daily from Day 1 to 42 and AN2898 ointment vehicle applied twice daily from Day 1 to 42 to a second target lesion (vehicle lesion). Target lesions were identified at Baseline (Day 1) by investigator.
AN2728 Ointment, 2% + Ointment Vehicle
Participants with mild to moderate AD applied AN2728 ointment, 2% to one target lesion (active lesion), topically twice daily from Day 1 to 42 and AN2728 ointment vehicle applied twice daily from Day 1 to 42 to a second target lesion (vehicle lesion). Target lesions were identified at Baseline (Day 1) by investigator.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline (Day 1) up to Day 42

Population: Safety analysis population included all randomized participants with confirmed usage of the study medication.

An AE was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. The SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death, initial or prolonged inpatient hospitalization, life-threatening experience (immediate risk of dying), persistent or significant disability or incapacity, congenital anomaly. Treatment-emergent were events between first dose of study medication and up to the end of study treatment (Day 42) that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events.
