Trial Outcomes & Findings for A Study (Study 1) to Evaluate the Safety and Efficacy of FMX103 1.5% Topical Minocycline Foam in the Treatment of Facial Papulopustular Rosacea (NCT NCT03142451)

NCT ID: NCT03142451

Last Updated: 2021-01-29

Results Overview

To determine the efficacy of FMX103 1.5% minocycline foam applied topically once daily for 12 weeks in the treatment of rosacea. Lesion counts included the number of papules, pustules, and nodules. Change from Baseline was calculated as the value at Baseline minus the post-Baseline value. Thus, a positive change reflects a reduction in lesion count.

PRIMARY outcome

Timeframe: Baseline and Week 12

Population: The intent-to-treat (ITT) population included all randomized participants. Analyses using the ITT population were based on the randomized treatment.

To determine the efficacy of FMX103 1.5% minocycline foam applied topically once daily for 12 weeks in the treatment of rosacea. Lesion counts included the number of papules, pustules, and nodules. Change from Baseline was calculated as the value at Baseline minus the post-Baseline value. Thus, a positive change reflects a reduction in lesion count.

PRIMARY outcome

Timeframe: Week 12

Population: The ITT population included all randomized participants. Analyses using the ITT population were based on the randomized treatment.

To determine the efficacy of FMX103 1.5% minocycline foam applied topically once daily for 12 weeks in the treatment of rosacea. The Investigator assessed the global severity of rosacea using the IGA scale. The scale ranges from 0 (Clear): No inflammatory papules or pustules to 4 (Severe): Many inflammatory papules or pustules, and up to 2 nodules. Higher scores indicated severe outcome. Treatment success was defined as an IGA score of 0 (clear) or 1 (almost clear), and at least a 2-step improvement (decrease) from Day 0/Baseline.

SECONDARY outcome

Timeframe: From Day 0/Baseline until the Safety Follow-up (4 weeks after Week 12 [Final Visit])

Population: The Safety (SAF) population included all randomized participants who used at least 1 dose of study drug, including participants who had no post-Baseline assessments unless all dispensed study drug was returned unused.

To evaluate the tolerability and safety of topical minocycline foam applied once daily for 12 weeks. A treatment-emergent adverse events (TEAE) was defined as any AE with an onset date on or after the first application of study drug, and before to the last application of study drug plus 3 days, having been absent pre-treatment or worsening relative to the pre-treatment state.
