A Study of Pegylated rhG-CSF as Support to Advanced Non-Small-Cell Lung Cancer (NSCLC) Patients Receiving Chemotherapy Receiving Chemotherapy

A Double-Blind, Placebo-Controlled, Multicenter, Randomized Study Evaluating the Prophylactic Use of Pegylated Recombinant Human Granulocyte Colony Stimulating Factor (rhG-CSF) on the Incidence of Neutropenia in Subjects With Advanced Non-Small-Cell Lung Cancer (NSCLC) Treated With Myelosuppressive Chemotherapy

Neutropenia is one of the most frequent adverse effects of chemotherapy, and the main factor to limit the dosage and the continuation of chemotherapy. A newly pegylated rhG-CSF was independently developed by JIANGSU HENGRUI Medicine Co., Ltd, China. Phase 1a, 1b and phase 2 trials have shown that pegylated rhG-CSF has decreased renal clearance, increased plasma half-life, and prolonged efficacy in compare with filgrastim. The purpose of this study is to determine the safety and effectiveness of pegylated rhG-CSF in preventing neutropenia following chemotherapy in patients with advanced NSCLC.
