Study Summary

Neurofibromatosis type 1 (NF1) is the most common genetic tumor predisposition syndrome, affecting up to 1 in 2500 individuals. Cutaneous neurofibromas are benign with self-limited growth; however, tumor burden may be excessive, tumors do not regress, and they can be disfiguring, painful, and itchy. Currently, the only treatment is surgery or laser ablation; however, outcomes are limited by the number of tumors that can be simultaneously removed, operating room availability, and painful recovery, with significant risk of regrowth. There is a strong need for noninvasive topical treatments for cutaneous neurofibromas. Diphencyprone (DPCP) is a "hapten" medication, a small molecule that activates the immune system when applied topically, which has been investigated as a cutaneous immunotherapy for other skin conditions. This is an open label Phase I study looking at safety and tolerability of this treatment as a primary endpoint, and tumor treatment as a secondary endpoint. Approximately 30 subjects will be enrolled at a single center within the US. Subjects with a clinical diagnosis of NF1 who have measurable disease and at least 4 cutaneous neurofibromas, will have DPCP applied topically to their neurofibromas once weekly for 10 weeks.

Primary Outcome

Safety of DPCP will be measured as the proportion of subjects with a grade 3 on the Common Terminology Criteria for Adverse Events (CTCAE) criteria. Specifically, the safety of DPCP will be assessed as per CTCAE for eczema, version 5.0.
