Abstract

Background: The incidence of epidermal growth factor receptor inhibitor (EGFRI)-induced papulopustular rash is 60-85%. Objective: To investigate prophylactic topical treatment for EGFRI-induced rash. Methods: A single-center, randomized, double-blind, placebo-controlled trial. Adult cancer patients initiating treatment with EGFRIs were randomized to receive facial topical treatment with chloramphenicol 3% + prednisolone 0.5% (CHL-PRED) ointment, chloramphenicol 3% (CHL) ointment, or aqua cream (AQUA). The primary end points were the incidence of ≥grade 3 rash using the Common Terminology Criteria for Adverse Events (CTCAE), on days 14 and 30. A subanalysis was conducted for incidence of a protocol-specified significant rash, defined as ≥10 facial papulopustular lesions. Results: The per-protocol analysis on day 14 included 69 patients, who received CHL-PRED (21), CHL (23), or AQUA (25). The incidence of CTCAE ≥grade 3 rash was not statistically significant between arms; however, the incidence of the protocol-specified significant rash was: CHL-PRED 14%, CHL 39%, and AQUA 48% (p = 0.03, CHL-PRED vs. AQUA). At 30 days, the CTCAE ≥grade 3 incidence was similar, but the incidences of protocol-specified significant rash were 6%, 16%, and 43% (p = 0.03, CHL-PRED vs. AQUA). No significant differences were found between CHL and CHL-PRED and between CHL and AQUA. Conclusions: Prophylactic topical CHL-PRED was efficacious when compared to AQUA, in the treatment of EGFRI-induced facial papulopustular rash.
