NFX-179
Brief summary
This study will enroll and treat subjects with cutaneous neurofibromas with NFX-179, a topical study drug. Eligible subjects will receive treatment for 28 days and be observed by a study doctor for approximately 56 days. Subjects will be randomly assigned to 1 of 4 treatment groups. 3 of the treatment groups will receive a specific dose NFX-179, and 1 group will receive placebo. The subject, study doctor, and NFlection Therapeutics will not know what treatment group each subject is assigned. Study participation requires at least 7 clinic visits, blood, urine, and tissue collection, images of the treated cutaneous neurofibromas, electrocardiograms, and information regarding the subject's medical and disease history.

Phospho-erk (p-ERK) Levels of Target cNF Tumors in NFX-179 Gel Group and Vehicle Gel Group After 28 Days of Once-daily (QD) Application
Pharmacodynamic activity (biochemical and physiologic effects of drugs) of NFX-179 Gel as defined by suppression of phospho-ERK (p-ERK) levels in Target cNF Tumors in each NFX-179 Gel group compared with the Vehicle Gel group after 28 days of once-daily (QD) application will be measured at Week 4
Time frame: Baseline through Week 4
Population: The p-ERK analysis included all available p-ERK data from tumors determined by histology to be cNF tumors. Missing data were due to missing or non-analyzable tumor samples or tumor samples shown to come from non-cNF tumors upon histologic review. Therefore the number of participants is not the same as those in the participant flow.
