Trial Outcomes & Findings for Treatment of Moderate to Severe Facial Acne Vulgaris (NCT NCT00612573)
NCT ID: NCT00612573
Last Updated: 2013-04-22
Results Overview
IGA: 0/clear (clear skin no lesions, inflammatory or non-inflammatory), 1/almost clear (rare non-inflammatory lesion w/no more than 1 small inflammatory lesion), 2/mild (some non-inflammatory lesions with no more than a few inflammatory lesions, papules/pustules only, no nodular lesions), 3/moderate (up to many non-inflammatory lesions, some inflammatory lesions, no more than 1 small nodular lesion), 4/severe (many non-inflammatory \& inflammatory lesions, no more than a few nodular lesions. Lower score improvement in score. Success=IGA decrease of at least 2 grades from baseline score.

PRIMARY outcome
Timeframe: Baseline to Week 12Population: ITT Population
Change derived as Baseline evaluation minus the Week 12 evaluation. Thus a positive change reflects a reduction in lesion count. Inflammatory Lesion Count includes nodules, papules and pustules.
