Trial Outcomes & Findings for GA YAZ ACNE in China Phase III (NCT NCT00818519)

NCT ID: NCT00818519

Last Updated: 2015-08-25

Results Overview

Acne lesions were counted by the trained designee over the entire face. All types of lesions were to be identified and separately counted, i.e., non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (total lesion count at Baseline - total lesion count at Cycle 6)/(total lesion count at Baseline)\*100, so that improvement is indicated by a larger percent change.

Participant Flow

Analyzed: 179 participants randomized, 173 in the FAS (Full Analysis Set): 87 in YAZ, 86 in placebo groups, 143 in the PPS (Per Protocol Set): 74 in YAZ, 69 in placebo groups

193 participants screened, 14 failed screening: withdrawal of consent (7), inclusion/exclusion criteria not met (6), participant lost/no further information available (1). study drug intake was unknown (3) and 3 participants to whom study drug was never administered (withdrawal of consent or lost to follow-up) were excluded from FAS.

PRIMARY outcome

Timeframe: Cycle 6 (Day 15±3 days of Treatment Cycle 6) and Baseline

Population: FAS

Acne lesions were counted by the trained designee over the entire face. All types of lesions were to be identified and separately counted, i.e., non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (total lesion count at Baseline - total lesion count at Cycle 6)/(total lesion count at Baseline)\*100, so that improvement is indicated by a larger percent change.
