12-week Study of NFX-179 Gel in Subjects With Epidermal Nevi

• Status: Not yet recruiting
• Trial end date: 2023-11-01
• Target enrollment: 0
• Participant gender: All

Summary

This study of NFX-179 is an open-label study, evaluating safety, tolerability, pharmacodynamic activity, and the clinical effect in subjects with Epidermal Nevus(ENS). NFX-179 is formulated as a gel for topical administration. NFX-179 has been shown in animal studies and in human extracts to suppress p-ERK with systemic absorption of NFX-179 following topical application to be extremely low, based on serum values observed in animal studies.

Primary objectives:

• To determine the pharmacodynamic activity of NFX-179 Gel as defined by suppression of phospho-ERK (p-ERK) levels in Target EN in treatment group after 12 weeks of once-daily (QD) application

• To determine the safety and tolerability of treatment with NFX-179 Gel 1.50% applied QD for 12 weeks.

Secondary objectives:

-Clinical effect of NFX-179 Gel 1.5% defined as the percent change in EN volume after 12 weeks of QD application

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

No waivers to the inclusion criteria are permitted.

Exclusion Criteria A potential subject who meets any of the following criteria will be excluded from participation in this study:

1. Subject has applied any of the following topical products in the previous 30 days on or in proximity to the Target EN that, in the investigator's opinion, impairs evaluation of the Target EN or which exposes the subject to an unacceptable risk by study participation:

• Topical glucocorticoid steroids

• Topical retinoids (e.g., tazarotene, tretinoin, adapalene)

• > 5% of an alpha-hydroxy acid (e.g., glycolic acid, lactic acid)

• Fluorouracil

• Imiquimod

2. The Target EN has ever been treated with a topical MEK inhibitor or a topical BRAF inhibitor

3. The Subject has used any of the following systemic medications in the noted time period:

• Systemic retinoids (e.g., etretinate, isotretinoin) in the previous 90 days

• Systemic MEK inhibitors in the previous 180 days

• Systemic BRAF inhibitors in the previous 180 days

4. Subject has a history of hypersensitivity to any of the ingredients in the study medications

5. Subject has any know intercurrent illness or physical condition that would, in the investigator's opinion, impair evaluation of the Target EN or which exposes the subject to an unacceptable risk by study participation

6. Subject has, in the Investigator's opinion, a clinically relevant history of liver disease, including viral hepatitis, current alcohol abuse, or cirrhosis

7. Subject has a history of metastatic disease, or active cancer (excluding non-melanoma skin cancer, Stage I cervical cancer, ductal carcinoma in situ of the breast, or Stage 0 chronic lymphocytic lymphoma) within the previous 5 years

8. 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 the Target EN or which exposes the subject to an unacceptable risk by study participation

9. Subject has participated in an investigational drug trial in which administration of an investigational study medication occurred within the previous 30 days No waivers to the exclusion criteria are permitted.
