Abstract
PURPOSE:Erlotinib is an epidermal growth factor receptor inhibitor approved for patients with advanced non-small-cell lung cancer (NSCLC) whose epidermal growth factor receptor expression status is positive or unknown. Although it is efficacious, erlotinib can cause skin toxicity. This prospective, randomized phase III trial examined the effect of prophylactic treatment of erlotinib-induced skin rash. PATIENTS AND METHODS: Patients receiving erlotinib in the second- or third-line setting for advanced NSCLC were randomly assigned to prophylactic minocycline (100 mg twice per day for 4 weeks), reactive treatment (after rash developed, per grade of rash), or no treatment unless severe (grade 3). Rash incidence and severity, time to maximal rash, time to resolution, and overall survival (OS) were compared among treatment groups. RESULTS: In all, 150 patients were randomly assigned, 50 to each of three treatment arms. The incidence of skin toxicity was 84% regardless of treatment arm. Prophylactic treatment with minocycline significantly lengthened the time to the most severe grade of rash. Grade 3 rash was significantly higher in the no-treatment arm. OS was not significantly different among treatment arms, but patients receiving prophylactic or reactive treatments had a longer OS (7.6 and 8 months, respectively) than those who received no rash treatment (6 months). Rash was not self-limiting. CONCLUSION: The incidence of all grades of rash did not differ statistically among the three arms, so the trial was negative. The incidence of grade 3 skin toxicities was reduced in patients who were treated with prophylactic minocycline or reactive treatment. Efficacy was not compromised. Prophylactic minocycline and reactive treatment are both acceptable options for the necessary treatment of erlotinib-induced rash in the second- or third-line setting of metastatic NSCLC.
