How does TEVIMBRA + zanidatamab + chemotherapy work?
TEVIMBRA + zanidatamab + chemotherapy are thought to work together to attack cancer from multiple angles. Each works in a distinct way: TEVIMBRA helps your immune system turn your T cells back on; zanidatamab binds to HER2 proteins on cancer cells to stop their growth and help your immune system attack them; and chemotherapy works to destroy cancer cells throughout your body.

Why are TEVIMBRA + zanidatamab-hrii + chemotherapy prescribed together?
Treatments for unresectable locally advanced or metastatic HER2+ GEA are often used in combination because different therapies work in different ways fight cancer.
Depending on whether your tumor tests positive for the HER2 biomarker, your doctor may recommend pairing TEVIMBRA with chemotherapy and zanidatamab-hrii.

How are TEVIMBRA + zanidatamab-hrii + chemotherapy given?
What is the infusion like?
The infusion may be given at your doctor’s office, an infusion center, or another healthcare location. A healthcare provider will place an IV in your arm or access your port. Your infusion appointment will likely take several hours. You can read a book, listen to music, or simply relax during this time. Your healthcare team will check on you often, and you can ask them for help if you need it. You may need to stay longer after the infusion to make sure you are not having any immediate reactions.

IMPORTANT SAFETY INFORMATION
TEVIMBRA works with your immune system. It can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.

- Liver problems: Yellowing of your skin or the whites of your eyes; severe nausea or vomiting; pain on the right side of your stomach area; dark urine; and bleeding or bruising more easily than normal.

What if I have a transplanted organ or tissue; or bone marrow transplant?
Rejection of a transplanted organ or tissue. Your healthcare provider should tell you what signs and symptoms you should report and monitor you, depending on the type of organ or tissue transplant that you have had. There may be complications, including graft-versus-host-disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells. These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with TEVIMBRA. Your healthcare provider will monitor you for these complications.
Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with TEVIMBRA. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines, or may delay or completely stop treatment with TEVIMBRA if you have severe side effects.
Before receiving TEVIMBRA, tell your healthcare provider about all of your medical conditions, including if you have immune system problems; received an organ or tissue transplant; received or plan to receive a stem cell transplant that uses donor stem cells (allogeneic); received radiation treatment to your chest area; or a condition that affects your nervous system, such as myasthenia gravis or Guillain-Barré syndrome; or are pregnant, plan to become pregnant, or are breastfeeding or plan to breastfeed. Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
Can I take TEVIMBRA while pregnant or breastfeeding?
TEVIMBRA can harm your unborn baby. If you are a female who can become pregnant, your healthcare provider will do a pregnancy test before you start treatment with TEVIMBRA. Use effective birth control during treatment and for 4 months after your last dose. Do not breastfeed during treatment and for 4 months after your last dose. Talk to your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with TEVIMBRA.
