A phase II study to evaluate prophylactic treatment of dacomitinib-induced dermatologic adverse events in EGFR-mutated advanced non-small cell lung cancer

Phase 2

• Conditions: non-small cell lung cancer

• Registration Number: JPRN-jRCTs071190015
• Lead Sponsor: Takayama Koichi

Brief Summary

This prospective trial aimed to evaluate the effect of prophylactic intervention for skin toxicities, due to dacomitinib treatment. We enrolled 41 patients. As for Primary endpoint,18 patients(43.9%) had skin toxicities(>= grade2) in initial 8 weeks. The Upper limit of 90%CI was over pre-planned threshold. Skin toxicities caused dose reduction of dacomitinib treatment in 8 patients(19.5%). Grade3 or more adverse events was 17 patients (41.5%). The most common adverse event was anorexia in 6 patients(14.6%).
