- Has a length that is ≥5mm and ≤14mm
- Has a width that is ≥5mm and ≤14mm
- Has a height that is ≥2mm.
- Target cNFs on the anterior trunk or upper extremities must have the following tumor dimensions:
- 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
- Subject agrees NOT to use tanning beds
- Subject is willing to forego treatment of each Target cNF, except protocol specified therapy, during the study
- Female subjects who are women of childbearing potential must have a negative urine pregnancy test result and be willing to use a protocol approved, contraceptive method for the duration of the study
- Subject is willing and able to follow all study instructions and to attend all study visits.
Exclusion Criteria:
Subject has used any of the following topical therapies within the specified period prior to Visit 1 on or in proximity to any Target cNF that, in the investigator's opinion, impairs evaluation of any the cNFs or which exposes the subject to an unacceptable risk by study participation:
- Corticosteroids; 30 days
- Prescription retinoids (e.g., tazarotene, tretinoin, adapalene); 30 days
- > 5% of an alpha-hydroxy acid (e.g., glycolic acid, lactic acid); 30 days
- Fluorouracil; 30 days
- Imiquimod; 30 days
- LASER, light (e.g., intense pulsed light [IPL], photo-dynamic therapy [PDT]) or other energy-based therapy; 180 days
- 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:
- Retinoids (e.g., etretinate, isotretinoin); 90 days
- MEK inhibitors; 180 days
- BRAF inhibitors; 180 days
- Subject has a history of hypersensitivity to any of the ingredients in the study medications
- Subject has any known intercurrent illness or physical condition 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, in the investigator's opinion, clinically relevant history of liver disease, including viral hepatitis, current alcohol abuse, or cirrhosis
- Subject has a history of metastatic disease, or active cancer (excluding nonmelanoma skin cancer, Stage I cervical cancer, ductal carcinoma in situ of the breast, or Stage 0 chronic lymphocytic lymphoma) within the previous 5 years
- 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

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
182 days
|
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).
|
182 days
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
182 days
|
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.
|
182 days
|
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.
|
182 days
|
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
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
