Abstract
PurposeTo describe the outcomes of a pharmacist-led multi-center, collaborative patient education and proactive adverse event management program in a community-based oncology setting.MethodsPatients with EGFR mutation-positive (EGFRm+) non-small cell lung cancer, newly prescribed with oral afatinib, and monitored as part of the Florida Cancer Specialists patient management program, were included in a retrospective, observational analysis. During follow-up, data were collected on adverse event frequency, and changes in afatinib dosing. Data analyses were descriptive and exploratory in nature.ResultsThe mean age of the 123 patients included in the analysis was 69 years, and 78% were female. At the time of the analysis, 3 patients had discontinued before receiving treatment, 89 patients had discontinued afatinib treatment, and 31 patients were continuing to receive afatinib treatment. The most common afatinib-related adverse events were diarrhea (85%), rash/skin reactions (58%), stomatitis/mucositis (19%), and paronychia (16%). Overall, 13% of patients discontinued due to afatinib-related adverse events. The median duration of treatment was 4 months in patients who discontinued due to adverse events, 6 months in those who discontinued for other reasons, and 18 months in those who were continuing to receive therapy. Afatinib dose-reductions were more frequent in patients continuing treatment versus those who discontinued due to adverse events (77% vs. 42%, respectively).ConclusionsFindings suggest that adverse events in patients with EGFRm + non-small cell lung cancer receiving afatinib can be successfully managed in a community-based, real-world setting with the help of collaborative pharmacist-led patient education, adverse event monitoring, and continuous support.
