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.
