Foamix Announces Positive Results from Phase 3 Open-Label Safety Study Evaluating FMX103 Topical Minocycline Foam for Treatment up to 1 Year
The open-label safety study enrolled a total of 505 patients, all of whom had completed 12 weeks of FMX103 or vehicle treatment in the preceding double-blind studies (FX2016-11 or FX2016-12). Patients continued on open-label treatment with FMX103 for up to an additional 40 weeks.
Four hundred and sixty-five (465) patients received FMX103 therapy for at least 26 weeks and 272 patients received FMX103 therapy for a total of 52 weeks, which is in excess of the subject sample size requirements specified in the regulatory guidance for this type of safety evaluation (ICH E1A, 1995). A total of 410 patients completed participation in the study. The key safety findings from the study are as follows:
- Non-cutaneous adverse events were comparable in type and frequency with those reported during the double-blinded portion of studies FX2016-11 and FX2016-12. The most frequently reported treatment-emergent adverse event was upper respiratory tract infection i.e. common cold (3.8%). Four (4) patients discontinued the study due to a non-application site adverse event – mydriasis, anemia/leukocytosis, appendicitis and enchondromatosis. No serious drug-related adverse events were reported.
- Cutaneous adverse events occurred in 1% or less of patients during the additional 40 weeks of open-label treatment with FMX103 with the most frequently reported treatment emergent adverse event being contact dermatitis (1.0%). Two (2) patients discontinued in the study for an application site adverse event – worsening of rosacea and contact dermatitis. In the assessment of facial dermal tolerability at Week 52, more than 95% of patients had either no signs or symptoms, or signs/symptoms that were classified “mild” (burning/stinging, flushing/blushing, dryness, itching, peeling and hyperpigmentation). The severity of key clinical manifestations of rosacea - erythema and telangiectasia - had both significantly improved when compared to Baseline of the preceding double-blind studies.
- Patient satisfaction with FMX103 treatment remained high when re-assessed at Week 52 which was consistent with scores obtained at Week 12 (end of double-blind studies).
Open label efficacy was also assessed as a secondary objective throughout the additional 40-week FMX103 treatment course. The key efficacy findings from the study were:
- Mean absolute reduction of inflammatory lesion count, compared to Baseline of the preceding double-blinded study (FX2016-11 or FX2016-12), was -23.0 for subjects treated with FMX103 for 52 weeks and –22.5 for subjects treated for 40 weeks. Corresponding mean inflammatory lesion counts at Baseline of the preceding double-blind studies for these groups were 28.8 and 28.7, respectively (all observed cases).
- The proportion of subjects achieving Investigator Global Assessment (IGA) treatment success at Week 52, defined as at least a 2-step improvement resulting in a 0 (clear) or 1 (almost clear) score compared to Baseline of the preceding double-blinded study (FX2016-11 or FX2016-12), was 81.6% for subjects treated with FMX103 for 52 weeks and 76.0% for subjects treated for 40 weeks (all observed cases).
“We are encouraged that our comprehensive safety evaluation has validated prior data from studies FX2016-11 and FX2016-12 demonstrating that FMX103 appears to be well tolerated with an acceptable overall safety profile and high patient satisfaction in the treatment of moderate-to-severe papulopustular rosacea,” said
“These impressive safety results underscore our belief that FMX103 has the potential to address significant unmet needs in the management of this difficult to treat condition. We are also pleased to see evidence of continued improvements in both inflammatory lesion reduction and in IGA treatment success scores beyond what was reported for the co-primary endpoints at Week 12,” said Dr
About Papulopustular Rosacea
Papulopustular rosacea is a chronic skin disease causing inflammatory lesions (papules and pustules) on the nose, cheeks, chin and forehead.
