Uses of Atezolizumab

Atezolizumab is a prescription medication used to treat urothelial carcinoma, a type of bladder and urinary tract cancer. This medication may be given to those:

  • whose cancer has spread or cannot be removed by surgery (advanced urothelial carcinoma), and
  • who are not able to take chemotherapy that contains a medicine called cisplatin, or
  • who have tried chemotherapy that contains platinum, and it did not work or is no longer working

Atezolizumab may be given to those who cannot receive chemotherapy that contains platinum as well as for those whose cancer has spread after chemotherapy that contains platinum as well as those whose cancer has spread within 12 months of receiving chemotherapy before surgery or after surgery.

Atezolizumab is also approved to treat non-small cell lung cancer (NSCLC) that has spread to other parts of the body and has progressed during or after receiving chemotherapy containing platinum. For those with a tumor that has an abnormal EGFR or ALK gene, atezolizumab can be given if an FDA-approved therapy for tumors with these abnormal genes has been tried and it did not work or is no longer working

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information
