What is Yervoy (ipilimumab)?

How Yervoy (ipilimumab) works

Yervoy (ipilimumab) is an immunotherapy medication. More specifically, it's a CTLA-4 inhibitor. It's also called a checkpoint inhibitor.

Yervoy (ipilimumab) works by blocking a protein called CTLA-4. CTLA-4 acts like a brake on certain immune cells in your body. This brake helps keep your immune system from becoming too active. But it can also make it harder for your immune cells to attack cancer cells.

By blocking CTLA-4, Yervoy (ipilimumab) takes the brake off your immune system. This helps your immune cells become more active and better able to attack cancer cells.

Pharmacist tips for Yervoy (ipilimumab)

pharmacist
  • Plan enough time for your Yervoy (ipilimumab) infusion appointments. The infusion takes about 30 minutes, but your full visit can take longer. You might need time to check in or receive other cancer medications. Consider bringing a book or something else to do while you wait.
  • Yervoy (ipilimumab) can be given by itself or with other cancer medications. If you get Opdivo (nivolumab) on the same day, you'll get Opdivo first and then Yervoy. If chemotherapy is also part of your treatment, you'll get it after Yervoy.
  • Tell your nurse right away if you don't feel well during the Yervoy (ipilimumab) infusion. Rarely, infusion reactions can happen. Signs can include itching, feeling warm, nausea, trouble breathing, or a fast heartbeat. Your care team can slow or stop the infusion if needed and help treat these symptoms.
  • Tell your cancer care team early about any new or worsening symptoms. Yervoy (ipilimumab) can cause your immune system to attack healthy parts of your body. Watch for symptoms like diarrhea, rash, itching, trouble breathing, or feeling very tired. These problems can happen during treatment or even after you stop Yervoy (ipilimumab).
  • Talk to your care team before treating new side effects on your own. For example, diarrhea from Yervoy (ipilimumab) might need more than an over-the-counter medication. Some side effects might need a steroid or other treatment.
  • Keep your lab appointments while taking Yervoy (ipilimumab). Your care team will check how well your liver, kidneys, and thyroid are working. These tests can help find immune-related problems before you notice symptoms.
  • If you can become pregnant: Use reliable birth control during treatment and for 3 months after your last Yervoy (ipilimumab) dose. This medication can harm an unborn baby. Tell your oncologist right away if you become pregnant during treatment.
  • If you're breastfeeding or plan to breastfeed: Don't breastfeed during treatment with Yervoy (ipilimumab) or for 3 months after your last dose. It's not known if the medication can pass into breast milk. But it could cause serious side effects in a breastfed baby. Talk to your oncologist or a lactation consultant about safe ways to feed your baby.

Risks and warnings for Yervoy (ipilimumab)

Yervoy (ipilimumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Immune-related side effects

Immunotherapy medications like Yervoy (ipilimumab) can cause immune-related adverse events (irAEs). These side effects happen when your immune system becomes too active. It causes your immune system to start attacking healthy cells, not just cancer cells.

These side effects can happen anywhere in your body and at any time while receiving Yervoy (ipilimumab). They can also sometimes appear after stopping the medication. These side effects can be mild or very serious.

Some side effects show up on your lab test results. These include liver, kidney, or thyroid problems. That's why it's important to get your blood work done on time, even if you feel fine. This helps your care team check for any side effects that you can't easily spot.

Other side effects can cause symptoms you can feel. Examples include diarrhea, rash, and trouble breathing. Tell your care team right away if you notice these symptoms or anything unusual. Depending on how severe your symptoms are, you might need to stop Yervoy (ipilimumab) for a while and take a steroid to help you feel better.

Infusion reactions

Rarely, serious reactions can happen during the Yervoy (ipilimumab) infusion. Tell your nurse right away if you feel itchy or warm, have trouble breathing, feel nauseous, or have a fast heartbeat during your infusion. Your care team might slow or stop the infusion to help. If the reaction is severe, you might need to stop Yervoy (ipilimumab) treatment.

Complications from stem cell transplants

  • Risk factors: People who’ve had a stem cell (bone marrow) transplant

Some people who take Yervoy (ipilimumab) either before or after a stem cell transplant can have serious problems. They can develop a problem called graft-versus-host disease (GVHD).

Before starting Yervoy (ipilimumab), tell your oncologist if you’ve had a stem cell transplant. They can weigh the risks and benefits of treatment. Also tell them if you have a stem cell transplant after Yervoy (ipilimumab). Your care team will follow up with you often to watch for GVHD.

Harm to an unborn baby

Based on animal studies and how it works, Yervoy (ipilimumab) might harm an unborn baby. If you can become pregnant, your care team might give you a pregnancy test before starting Yervoy (ipilimumab). Use birth control during treatment and for 3 months after your last dose. Tell your care team right away if you become pregnant during treatment.
