Generic name:  atezolizumab  [ A-te-zoe-LIZ-ue-mab ]
Drug class:  Anti-PD-1 monoclonal antibodies

What is Tecentriq?

Tecentriq is a monoclonal antibody that affects the actions of the body’s immune system. It works to strengthen your immune system to help your body fight against tumor cells.

Tecentriq belongs to a class of drugs called programmed death-ligand 1 (PD-L1) inhibitors. It blocks interactions in the PD-1/PD-L1 pathway (proteins found on the body’s immune cells and some cancer cells) to help the body’s immune system fight cancer cells.

What is Tecentriq used to treat?

Tecentriq is used to treat adults with:

• a type of  bladder and urinary tract cancer  called urothelial carcinoma. Tecentriq may be used when your bladder cancer has spread or cannot be removed by surgery, and if you have any one of the following conditions:
  • you are not able to take chemotherapy that contains a medicine called cisplatin, and your cancer tests positive for “PD-L1”, or
  • you are not able to take chemotherapy that contains any platinum regardless of “PD-L1” status.
• a type of lung cancer called  non-small cell lung cancer  (NSCLC).
  • Tecentriq may be used alone as a treatment for your lung cancer:
    • to help prevent your lung cancer from coming back after your tumor(s) has been removed by surgery and you have received platinum-based chemotherapy, and
    • you have stage 2 to stage 3A NSCLC (talk to your healthcare provider about what these stages mean), and
    • your cancer tests positive for “PD-L1”.
  • Tecentriq may be used alone as your first treatment when your lung cancer:
    • has spread or grown, and
    • your cancer tests positive for “high PD-L1”, and
    • your tumor does not have an abnormal “EGFR” or “ALK” gene.
  • Tecentriq may be used with the medicines bevacizumab, paclitaxel, and carboplatin as your first treatment when your lung cancer:
    • has spread or grown, and
    • is a type called “non-squamous NSCLC”, and
    • your tumor does not have an abnormal “EGFR” or “ALK” gene.
  • Tecentriq may be used with the medicines paclitaxel protein-bound and carboplatin as your first treatment when your lung cancer:
    • has spread or grown, and
    • is a type called “non-squamous NSCLC”, and
    • your tumor does not have an abnormal “EGFR” or “ALK” gene.
  • Tecentriq may also be used alone when your lung cancer:
    • has spread or grown, and
    • you have tried chemotherapy that contains platinum, and it did not work or is no longer working.
    • if your tumor has an abnormal “EGFR” or “ALK” gene, you should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working.
• a type of lung cancer called  small cell lung cancer  (SCLC). Tecentriq may be used with the chemotherapy medicines carboplatin and etoposide as your first treatment when your lung cancer
  • is a type called “extensive-stage SCLC,” which means that it has spread or grown.
• a type of  liver cancer  called hepatocellular carcinoma (HCC). Tecentriq may be used with the medicine bevacizumab when your liver cancer:
  • has spread or cannot be removed by surgery, and
  • you have not received other medicines by mouth or injection through your vein (IV) to treat your cancer.
• a type of skin cancer called  melanoma . Tecentriq may be used with the medicines cobimetinib and vemurafenib when your melanoma:
  • has spread to other parts of the body or cannot be removed by surgery, and
  • has a certain type of abnormal “BRAF” gene. Your healthcare provider will perform a test to make sure this Tecentriq combination is right for you.

It is not known if this medicine is safe and effective in children.

Your doctor may perform a biopsy to test your cancer for a protein called “PD-L1,” or a specific genetic marker (an abnormal “EGFR” or “ALK” or “BRAF” gene).

Warnings

Tecentriq affects your immune system and may cause it to attack normal healthy tissues or organs, leading to serious or life-threatening medical problems.

Call your doctor at once if you have new or worsening symptoms such as: chest pain, cough, breathing problems, stomach pain, vomiting, changes in appetite or weight, increased thirst or urination, headaches, neck stiffness, vision problems, tiredness, mood changes, muscle weakness, bleeding or bruising, bloody or tarry stools, dark urine, or yellowing of the skin or eyes.

Before taking this medicine

You should not use Tecentriq if you are allergic to atezolizumab.

To make sure Tecentriq is safe for you, tell your doctor if you have:

• an infection;
• an immune system disorder such as  lupus ,  ulcerative colitis , or  Crohn’s disease ;
• an  organ transplant ;
• radiation treatment to your chest area;
• a breathing disorder;
• liver disease ; or
• a nervous system disorder such as  myasthenia gravis  or Guillain Barré syndrome.

Tell your doctor if you plan to receive a stem cell transplant using donor stem cells.

You may need to have a negative pregnancy test before starting this treatment.

Do not use Tecentriq if you are pregnant. It could harm the unborn baby. Use effective  birth control  to prevent pregnancy while you are using this medicine and for at least 5 months after your last dose.

Tecentriq may affect fertility (ability to have children) in women. However, it is important to use birth control to prevent pregnancy because atezolizumab can harm an unborn baby.

You should not breastfeed while using atezolizumab and for at least 5 months after your last dose.

How is Tecentriq given?

Tecentriq is given as an infusion into a vein, usually once every 2 or 4 weeks. A healthcare provider will give you this injection.

This medicine must be given slowly, and the infusion can take up to 60 minutes to complete.

If you receive Tecentriq to treat a type of skin cancer called melanoma, you will also be given two other medications to take by mouth. Follow your doctor’s dosing instructions very carefully.

You may be given other medications to help treat certain serious side effects. Keep using these medicines for as long as your doctor has prescribed.

Tecentriq helps your immune system fight against tumor cells, but your immune system may attack normal healthy tissues or organs. When this happens, you may develop serious or life-threatening medical problems. You will need frequent medical tests.

Your doctor will determine how long to treat you with this medicine.
