Official title

A Phase I, Open Label Study Employing the Topical Immunomodulator Diphencyprone to Treat Cutaneous Neurofibromas Associated With NF1

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
