Trade Name: Portrazza®
For which conditions is this drug approved? Portrazza is approved for use in combination with the chemotherapy drugs Gemzar® (gemcitabine) and Platinol® cisplatin for first-line treatment of patients with metastatic squamous non-small cell lung cancer.
What is the mechanism of action? Portrazza belongs to a class of drugs known as monoclonal antibodies (a type of protein made in the laboratory that can bind to substances in the body, including cancer cells). Specifically, Portrazza targets the epidermal growth factor receptor (EGFR), a protein located on the surface of many cancer cells that is involved in cancer growth. By blocking the EGFR pathway, Portrazza helps keep cancer cells from growing.
How is Portrazza typically given (administered)? You’ll receive Portrazza as an intravenous (into the vein) infusion. A healthcare professional will give you the infusion, which will take 60 minutes, on the first and eighth day of each three-week cycle. After the Portrazza infusion, you’ll receive the Gemzar and Platinol infusion.
