Brief Summary:
This is a randomized, double-blind, vehicle-controlled, parallel group dose response study evaluating the safety and effectiveness of 2 concentrations of NFX-179 Gel in subjects with cutaneous neurofibromas. At Visit 1, the investigator will identify 10 Target cNFs that fulfil the enrollment criteria. The Target cNFs must be located on the subject's face, anterior trunk, or upper extremities. Two Target cNFs must be on the face and 8 must be on the anterior trunk or upper extremities. The study medication will be applied topically QD to the Target cNFs for 182days (26 weeks). During the duration of the study subjects will be evaluated for safety and efficacy.

Primary Outcome Measures :
- Safety and effectiveness of once daily NFX-179 gel treatment for 182 days measured by local tolerability assessments, safety laboratory tests, and target cNF volume reduction [ Time Frame: 182 days ]Safety will be measured by routine safety laboratory tests (CBC/differential, serum chemistry, urinalysis), and local tolerability assessment where the investigator will assess erythema, edema, scabbing/crusting, vesiculation, and erosion. The subject will assess stinging, burning, and pruritus. All assessments are performed using a 4-point scale (0 none, 1 mild, 2 moderate, 3 severe). Effectiveness will be measured by the percent of treated subjects with at least a 50% reduction in cNF volume after 6 months of treatment.
- Safety of once daily NFX-179 gel treatment for 182 days by adverse events and serious adverse events assessments [ Time Frame: 182 days ]Safety of NFX-179 gel compared to the vehicle group will be measured by the assessment and occurrence of new and ongoing adverse events (AEs)/serious adverse events (SAEs).
Secondary Outcome Measures :
- Percent of subjects with at least 50% Target cNF volume reduction after 182 days [ Time Frame: 182 days ]Treatment effectiveness will be measured by the percent of treated subjects with at least a 50% reduction in cNF volume after 6 months of treatment. Tumor volume will be measured by ruler measurements and two-dimensional photography. All modes of tumor volume measurement are reported in cubic millimeters.
- Percent change in cNF volume over 182 days [ Time Frame: 182 days ]Percent change of tumor volume will be calculated through ruler measurements and two-dimensional photography throughout the course of treatment. All modes of tumor volume measurement are reported in cubic millimeters.
- Physician's Tumor Assessment of Target cNF severity over 182 days [ Time Frame: 182 days ]Effect of treatment with The Physician Tumor Assessment is the investigator's assessment of the average overall severity of each Target cNF tumor at a particular time point. The Physician Tumor Assessment is a 5-point measuring tumor severity (0 clear/none, 1 almost clear, 2 mild, 3 moderate, 4 severe). This assessment is performed at Screening, Baseline/Day 1, Days 58, 183, and 211.
- Subject's Self-Assessment of Target cNF severity over 182 days [ Time Frame: 182 days ]The Subject Self-Assessment is the subject's assessment of the average overall severity of each Target cNF at a particular time point and is not a comparison with any other time point. The Subject Self-Assessment is a 5-point measuring tumor severity (0 clear/none, 1 almost clear, 2 mild, 3 moderate, 4 severe). This assessment is performed at Screening, Baseline/Day 1, Days 58, 183, and 211.
Other Outcome Measures:
- Patient Reported Outcome Measure to assess Target cNF symptoms over 182 days [ Time Frame: 182 days ]This assessment is performed via the subject's assessment of their experience over the previous week with 9 items for each Target cNF (sensitivity, pain, itch, noticeability, size, appearance, care to avoid irritation, how much the cNF bothers the subject, self-consciousness). Each item is assessed by using a 5-point scale.

Criteria
Inclusion Criteria:
- Subject is at least 18 years of age
- Subject must provide written informed consent prior to any study procedures
- Subject must have a clinical diagnosis of NF1
-
Subject has 10 clinically diagnosed Target cNFs with preferably 2 Target cNFs located on the face and 8 Target cNFs located on the anterior trunk or upper extremities. Alternatively, at least 1 Target cNF is located on the face, in which case 9 Target cNFs must be located on the anterior trunk or upper extremities. Each Target cNF must meet the following criteria:
- Has, in the investigator's opinion, a clinically typical appearance

- Is a discrete cNF surrounded by sufficient non-affected skin that, in the investigator's opinion:
- The dimensions can be measured
- The perimeter can be outlined in the study photographs
- Is not irritated (e.g., bleeding, inflamed)
- Is not in an area subject to repeated trauma (e.g., area that is shaved, on the beltline, under a bra strap, etc.)
- Does not have an active cutaneous infection

- Has a length that is ≥7mm and ≤14mm
- Has a width that is ≥5mm and ≤14mm
- Has a height that is ≥2mm.
- Subject agrees to avoid exposure of Target cNFs to excessive sunlight and to use her/his routine sunscreen if excessive exposure cannot be avoided

- MEK inhibitor or BRAF inhibitor; ever.
-
The subject has used any of the following systemic medications therapies within the specified period prior to Visit 1:

- Subject has any condition (e.g., other skin conditions or diseases, metabolic dysfunction, physical examination findings, clinical laboratory findings) or situation (e.g., vacation, scheduled surgery) that would, in the investigator's opinion, impair evaluation of a Target cNF or which exposes the subject to an unacceptable risk by study participation
- Subject has participated in an investigational drug trial in which administration of an investigational study medication occurred within the previous 30 days
