What is Ipilimumab (Yervoy) used for?
Ipilimumab is a cancer medicine that is used alone or in combination with other medicines to treat certain types of cancer such as:
- Skin cancer (melanoma);
- Non-small cell lung cancer (NSCLC);
- Pleural mesothelioma (cancer that affects the lining of the lungs and chest wall);
- Squamous cell cancer of the esophagus;
- Kidney cancer;
- Liver cancer; or
- Colorectal cancer that has certain specific DNA mutations.
Ipilimumab is often given when the cancer has spread to other parts of the body, or cannot be surgically removed, or has come back after prior treatment.
Ipilimumab is given for NSCLC only if your tumor tests positive for “PD-L1” and does not have an abnormal “EGFR” or “ALK” (a specific genetic marker).
Ipilimumab may also be used for purposes not listed in this medication guide.

Mechanism of action
Cytotoxic T-lymphocyte antigen-4 (CTLA-4) is an inhibitory molecule that competes with the stimulatory CD28 for binding to B7 on antigen presenting cells.3 CTLA-4 and CD28 are both presented on the surface of T-cells. Ipilimumab is a human IgG1 that binds CTLA-4, preventing the inhibition of T-cell mediated immune responses to tumors.
Drug Interactions
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Other Interactions
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

What is the dosage of ipilimumab (Yervoy)?
Yervoy alone is given to you into your vein through an intravenous (IV) line over 90 minutes.
- When Yervoy is used in combination with nivolumab, nivolumab is given to you into your vein through an IV line over 30 minutes. Then Yervoy is also given through an IV over 30 minutes on the same day.

What special precautions should I follow?
Before receiving ipilimumab injection,
- Tell your doctor and pharmacist if you are allergic to ipilimumab injection, any other medications, or any of the ingredients in ipilimumab injection. Ask your pharmacist or check the Medication Guide for a list of the ingredients.
- Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- Tell your doctor if you have received or plan to receive a stem cell transplant that uses donor stem cells (allogeneic) or have ever had an organ transplant. Also, tell your doctor if you have or have ever had an autoimmune disease (condition in which the immune system attacks a healthy part of the body) such as Crohn’s disease (condition in which the immune system attacks the lining of the digestive tract causing pain, diarrhea, weight loss, and fever), ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum), lupus (a condition in which the immune system attacks many tissues and organs including the skin, joints, blood, and kidneys); any condition that affects your nervous system such as myasthenia gravis (a disorder of the nervous system that causes muscle weakness) or Guillain-Barré syndrome (weakness, tingling, and possible paralysis due to sudden nerve damage); thyroid problems; or liver disease.
- Tell your doctor if you are pregnant or plan to become pregnant. You will need to take a pregnancy test before you receive ipilimumab. You should use effective birth control to prevent pregnancy during your treatment with ipilimumab injection and for 3 months after your final dose. Talk to your doctor about birth control methods that will work for you. If you become pregnant while receiving ipilimumab injection, call your doctor immediately. Ipilimumab injection may harm the fetus.
