Safety and Efficacy Study of GCSF Therapy to Treat Patients at High Risk for Chemotherapy Induced Severe Neutropenia

An Open-Label, Dose Finding, Prospective, Multi Center, Randomized, Parallel Group Study to Assess the Efficacy and Safety of Three Different Dose Levels of AVI 014 (G-CSF) Compared With a Standard Dose of Neupogen® in Breast Cancer Patients at High (>20%) Risk for Chemotherapy Induced Severe Neutropenia

The overall purpose of this study is to assess the dose response, efficacy, and safety of three different dose levels of AVI 014 (granulocyte colony-stimulating factor [G-CSF]) in breast cancer patients at high (>20%) risk for chemotherapy-induced severe neutropenia.

Study Overview

• Status: Completed
• Conditions: Breast Cancer; Neutropenia
• Intervention / Treatment: Drug: AVI-014 versus Filgrastim

Detailed Description

Filgrastim is a recombinant human G-CSF (rhG-CSF) developed in the mid 1980s, and was approved by the United States (US) Food and Drug Administration (FDA) for use in chemotherapy induced neutropenia in 1991 under the trade name Neupogen®. Filgrastim was first approved in the EU in Germany in 2001 under the same trade name. Filgrastim is a non glycosylated protein, produced in E. coli bacteria transfected with rhG-CSF copy deoxyribonucleic acid (cDNA). Filgrastim differs from native human G CSF only in the addition of an N terminal methionine required for expression in a bacterial host. In 2002, a pegylated filgrastim with extended duration of action relative to the naked filgrastim was approved by the FDA and the EU Commission under the trade name Neulasta.

AviGenics has generated transgenic hens carrying rhG CSF cDNA, which express a glycosylated form of rhG-CSF protein in their egg white. The purified rhG-CSF is biologically active, as assessed by its in vitro binding and cell proliferation activities, and has been fully characterized by AviGenics. AviGenics intends to develop this product to treat chemotherapy-induced neutropenia.

The overall goal of this study is to assess dose response, efficacy, and safety of three different dose levels of AVI-014 (G-CSF) in breast cancer patients at high (>20%) risk for chemotherapy induced severe neutropenia.
