Background: Clinical trials addressing the acneiform rash associated with epidermal growth factor receptor inhibitors are lacking. Objective: We evaluated the ability of topical pimecrolimus to reduce the severity of cetuximab-related facial rash. Methods: In all, 24 patients with metastatic colorectal cancer with cetuximab facial rash received twice daily pimecrolimus application for 5 weeks to half of the face. At baseline, week 2, and week 5, a dermatologist performed facial lesion counts, patients reported perceived severity of rash-related symptoms, and standardized facial photographs were obtained for blinded evaluation of global rash severity. Results: Treatment sides had greater decrease in lesion counts than observation sides of face at weeks 2 (P < .001) and 5 (P = .02). However, there were no significant differences in patients' assessment of symptoms and in review of facial photographs for rash severity between treatment and observation sides. Limitations: This study was not placebo controlled. Conclusions: Pimecrolimus application did not translate into clinically meaningful benefit for patients with cetuximab-related facial rash.
