Topical Aprepitant (HT-001): A Novel Therapy for Epidermal Growth Factor Receptor Inhibitor-Associated Papulopustular Eruptions.

Papulopustular eruptions are the most common dermatologic side effect of epidermal growth factor receptor inhibitor (EGFRI) therapy. Topical corticosteroids and oral tetracyclines are frequently used to manage these eruptions, though these treatments are limited by their adverse effects and efficacy. Results from preclinical studies suggest a role for topical aprepitant (HT-001) in the treatment of EGFRI-induced skin toxicities. Herein a case of EGFRI-induced papulopustular eruption with rapid treatment response to topical aprepitant (HT-001) 2% cream is described and the literature reviewed.
