Why is Atezolizumab (Tecentriq) Prescribed?
Atezolizumab is an immunotherapy that works by activating the immune system to fight against the cancer cells, and helps to slow tumor growth. Atezolizumab works for several cancers and is used:
- to treat certain types of urothelial cancer (cancer of the lining of the bladder and other parts of the urinary tract) that has spread or cannot be removed by surgery in people unable to receive platinum-containing chemotherapy (carboplatin, cisplatin) or whose condition has worsened during or after treatment with platinum-containing chemotherapy medication,
- alone or with other chemotherapy medications as a first treatment for certain types of non-small cell lung cancer (NSCLC) that has spread to other parts of the body,
- to treat a certain type of NSCLC that has spread to other parts of the body and that has worsened during or after treatment with other chemotherapy medications,
- together with other chemotherapy medications as a first treatment for a certain type of small cell lung cancer (SCLC) that has spread throughout the lung or to other parts of the body,
- together with other chemotherapy medications as a treatment for a certain type of breast cancer that has spread to other parts of the body or cannot be removed by surgery,
- in combination with bevacizumab (Avastin) to treat hepatocellular carcinoma (HCC or liver cancer) that has spread or cannot be removed by surgery in people who have not previously not received chemotherapy, and
- in combination with cobimetinib (Cotellic) and vemurafenib (Zelboraf) to treat certain types of melanoma (a type of skin cancer) that has spread or cannot be removed by surgery.
How is Atezolizumab Given?
Atezolizumab infusion is given into a vein over 30 to 60 minutes by a doctor or nurse in a hospital or medical facility. For urothelial cancer, NSCLC, SCLC, or HCC, it is usually given once every 2-4 weeks depending on your dosage for as long as your doctor recommends that you receive treatment. It is usually given on days 1 and 15 as part of a 28-day cycle for breast cancer. For melanoma, it is usually injected every 2 weeks. The length of your treatment depends on how well your body responds to the medication and the side effects that you experience.
Atezolizumab injection may cause serious reactions during the infusion of the medication. A doctor or nurse will monitor you carefully while you are receiving the medication. If you experience any of the following symptoms, tell your doctor immediately: flushing, fever, chills, shaking, dizziness, feeling faint, shortness of breath, difficulty breathing, itching, rash, back or neck pain, or swelling of the face or lips.
Your doctor may need to slow down your infusion, delay or stop your treatment, or treat you with other medications if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with atezolizumab injection.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with atezolizumab injection and each time you receive the medication. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer’s website to obtain the Medication Guide.
