What Tecentriq is

Tecentriq is an anti-cancer medicine that contains the active substance atezolizumab.

• It belongs to a group of medicines called monoclonal antibodies.
• A monoclonal antibody is a type of protein designed to recognise and attach to a specific target in the body.
• This antibody can help your immune system fight your cancer.

What Tecentriq is used for

Tecentriq is used in adults to treat:

• A kind of bladder cancer, called urothelial carcinoma
• A kind of lung cancer, called non-small cell lung cancer
• A kind of lung cancer, called small cell lung cancer

Patients get Tecentriq when their cancer has spread to other parts of the body or come back after previous treatment.

Tecentriq may be given in combination with other anticancer medicines. It is important that you also read the package leaflets for the other anticancer medicines you may be receiving. If you have any questions about these medicines, ask your doctor.

How Tecentriq works

Tecentriq works by attaching to a specific protein in your body called programmed death-ligand 1 (PD-L1). This protein suppresses the body’s immune (defense) system, thereby protecting cancer cells from being attacked by the immune cells. By attaching to the protein, Tecentriq helps your immune system to fight your cancer.

You must not be given Tecentriq if:

• you are allergic to atezolizumab or any of the other ingredients of this medicine (listed in section 6).

If you are not sure, talk to your doctor or nurse before you are given Tecentriq.

• have had serious side effects because of other antibody therapies that help your immune system to fight cancer
