Rationale and design of a phase II study to evaluate prophylactic treatment of dacomitinib-induced dermatologic adverse events in epidermal growth factor receptor-mutated advanced non-small cell lung cancer (SPIRAL-Daco study)

Dacomitinib is the first second-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) to significantly improve overall survival in the patients of EGFR mutation-positive inoperable or postoperative recurrent non-small cell lung cancer (NSCLC). However, dermatologic adverse events (AEs) increase with dacomitinib treatment, and the management strategy for dermatologic AEs is crucial. In particular, a proactive strategy has become desirable in clinical practice settings. We designed a trial to assess a proactive strategy for dermatologic AEs associated with dacomitinib treatment.
