Atezolizumab is a type of targeted therapy drug called an immune checkpoint inhibitor. It is a monoclonal antibody that works by binding to the protein PD-L1 on the surface of some cancer cells, which keeps cancer cells from suppressing the immune system. This allows the immune system to attack and kill the cancer cells.
Use in Cancer
Atezolizumab is approved to be used alone or with other drugs to treat:
- Alveolar soft part sarcoma that has spread to other parts of the body or cannot be removed by surgery. Atezolizumab is used alone in adults and children aged 2 years and older.
- Hepatocellular carcinoma (a type of liver cancer) that has spread to other parts of the body or cannot be removed by surgery. Atezolizumab is used with bevacizumab in patients who have not received systemic therapy.
- Melanoma that has a certain mutation in the BRAF gene. Atezolizumab is used with cobimetinib fumarate and vemurafenib in adults whose cancer has spread to other parts of the body or cannot be removed by surgery.
- Non-small cell lung cancer. Atezolizumab is used:
- After surgery and platinum chemotherapy in adults with stage IIA, stage IIB, or stage IIIA cancer that has the PD-L1 protein.
- As the first treatment in adults whose cancer has spread to other parts of the body, has the PD-L1 protein, and does not have a mutation in the EGFR gene or the ALK gene.
- With bevacizumab, paclitaxel, and carboplatin or paclitaxel albumin-stabilized nanoparticle formulation and carboplatin as the first treatment in adults with non-squamous cancer that does not have a mutation in the EGFR gene or ALK gene that has spread to other parts of the body.
- In adults whose cancer has spread to other parts of the body and got worse during or after treatment with platinum chemotherapy. For patients whose cancer has a mutation in the EGFR gene or ALK gene, atezolizumab is used if their cancer has gotten worse after treatment with FDA-approved therapy for these mutations.
- Small cell lung cancer. Atezolizumab is used with carboplatin and etoposide as the first treatment in adults with extensive-stage cancer.
Atezolizumab is also being studied in the treatment of other types of cancer.
