Trial Outcomes & Findings for Long-term Study of Efficacy/Safety of Adapalene/Benzoyl Peroxide Topical Gel in Acne Vulgaris Subjects (NCT NCT00446043)

NCT ID: NCT00446043

Last Updated: 2023-07-11

Results Overview

Percent change in inflammatory, noninflammatory and total lesions at Month 12 was measured from baseline lesions. The noninflammatory lesion count was the sum of open comedones (a mass of sebaceous material that is impacted behind an open follicular orifice (blackhead) and closed comedones (a mass of sebaceous material that is impacted behind a closed follicular orifice (whitehead). The inflammatory lesion count was the sum of papules (a small, solid elevation less than 1.0 cm in diameter) and pustules (a small, circumscribed elevation of the skin that contains yellow-white exudate). The total lesion count was the sum of inflammatory and noninflammatory lesions. Missing adapalene and benzoyl peroxide data were imputed using last observation carried forward (LOCF).

Timeframe: Baseline up to Month 14

Population: The safety population was defined as all participants enrolled who had applied study medication at least once.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. 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/incapacity; congenital anomaly.
