A Study Comparing Pegylated rhG-CSF and rhG-CSF as Support to Breast Cancer Patients Receiving Chemotherapy

January 5, 2013 updated by: Jiangsu HengRui Medicine Co., Ltd.
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 rhG-CSF. The purpose of this study is to determine the safety and effectiveness of pegylated rhG-CSF in preventing neutropenia following chemotherapy in patients with breast cancer.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Pegylated rhG-CSF: 100µg/kg
Chemtherapy naive patients receiving chemotherapy and Pegylated rhG-CSF 100µg/kg
Patients were administered pegylated rhG-CSF 100 ug/kg once at the 3rd day of every chemotherapy cycle. Chemotherapy regimen: EC (epirubicin 100 mg/m2 +cyclophosphamide 600 mg/m2) or ET (epirubicin 75 mg/m2 + docetaxel 75 mg/m2).
Experimental: Pegylated rhG-CSF: 6mg
Chemtherapy naive patients receiving chemotherapy and Pegylated rhG-CSF 6mg
Patients were administered pegylated rhG-CSF 6mg once at the 3rd day of every chemotherapy cycle. Chemotherapy regimen: EC (epirubicin 100 mg/m2 +cyclophosphamide 600 mg/m2) or ET (epirubicin 75 mg/m2 + docetaxel 75 mg/m2).
Active Comparator: rhG-CSF 5ug/kg/day
Chemtherapy naive patients receiving chemotherapy and rhG-CSF 5ug/kg/day
Patients were administered pegylated rhG-CSF 6 ug/kg/day from the 3rd day of every chemotherapy cycle. Chemotherapy regimen: EC (epirubicin 100 mg/m2 +cyclophosphamide 600 mg/m2) or ET (epirubicin 75 mg/m2 + docetaxel 75 mg/m2).
