Trial Outcomes & Findings for A Study to Compare the Efficacy and Safety of Topical Administration of FMX-101 for Treatment of Moderate-to-Severe Acne (NCT NCT02815267)

Last Updated: 2022-01-18

Results Overview

To evaluate the efficacy in the treatment of acne compared to vehicle of topical FMX101 4% administered daily for 12 weeks. Changes from Baseline are calculated as Baseline value minus post-Baseline value, so that decreases appear as positive values. Inflammatory lesion count included: papules, pustules, and nodules.

Participant Flow

The study was conducted at 35 sites in the United States and one site in the Dominican Republic from 06 May 2016 to 13 October 2017.

The study consisted of a varied screening period. All participants underwent inclusion and exclusion criteria assessment and all eligible participants signed the informed consent before undergoing any study related procedures. All assessments at screening were done as per the schedule of assessment.

PRIMARY outcome

Timeframe: Baseline and Week 12

Population: An ITT population: included all randomized participants.

The IGA scale for acne vulgaris, was used by the investigators to assess the severity of a participant's acne vulgaris. The scale ranges from 0 (Clear): normal, clear skin with no evidence of acne vulgaris to 5 (Very Severe): highly inflammatory lesions predominate, variable number of comedones, many papules/pustules and many nodulocystic lesions. Higher scores indicated severe outcome. Treatment success was defined as an IGA score of 0 (score of clear) or 1 (almost clear), and at least a 2-grade improvement (decrease) from Baseline.

Timeframe: Baseline and Week 12

Population: An ITT Population: included all randomized participants.

To evaluate the efficacy in the treatment of acne compared to vehicle of topical FMX101 4% administered daily for 12 weeks. Percent change from Baseline is calculated as the Baseline value minus the post-Baseline value divided by the baseline value, expressed as a percentage. Non-inflammatory lesions included: open comedones (blackhead) and closed comedones (whitehead).

SECONDARY outcome

Timeframe: Double blind: Screening Day until Week 12; Open-label: Week 16 until Week 52

Population: Safety population: included all randomized participants who received IP. Participants who had no post-Baseline assessments were included in the Safety population unless all dispensed IP was returned unused.

To evaluate the safety compared to vehicle of topical FMX101 4% administered daily for 12 weeks and to evaluate the long-term safety of topical FMX101 4% administered daily for up to an additional 40 weeks. TEAEs of the double-blind phase were defined as AEs starting on or after date of first application of investigational product (IP), but before the date of the first application of the open-label phase, and AEs starting on or after the first application of the open-label phase are considered as TEAEs of the open-label phase.
