Docetaxel Plus Ramucirumab With Primary Prophylactic Pegylated Granulocyte-Colony Stimulating Factor Support for Elderly Patients With Advanced NSCLC: A Multicenter Prospective Single Arm Phase 2 Trial: DRAGON Study (WJOG9416L)

Docetaxel plus ramucirumab could be a promising treatment for chemo-naive elderly patients with NSCLC, but high incidence of febrile neutropenia (FN) is a critical concern. We thus adopted a routine primary prophylactic pegylated-granulocyte-colony stimulating factor (PEG-G-CSF) to reduce FN and maximize the efficacy of docetaxel plus ramucirumab in elderly patients.
