How ACTEMRA Works
How ACTEMRA is thought to work for systemic JIA
To understand how ACTEMRA may work, let’s start with what may contribute to systemic JIA (SJIA). SJIA occurs when the immune system, the system that protects the body by attacking harmful bacteria and viruses, starts targeting healthy cells.
In a healthy immune system, many different cells protect the body by fighting harmful bacteria and viruses. Our immune system uses messengers called cytokines to tell these cells when and where to attack.
There are many different types of cytokines, including:
- Interleukin-1 (IL-1)
- Interleukin-6 (IL-6)
In most patients with systemic JIA (SJIA), there are too many cytokine messengers in their bodies. This causes the immune system to attack healthy cells, which can contribute to the signs and symptoms of SJIA.
Take the cytokine IL-6, for example. In order for IL-6 to cause cell
activation, it needs to connect to the cell. ACTEMRA works by blocking
IL-6 from connecting to the cell.
Important Safety Information
Before taking ACTEMRA, tell your child’s healthcare provider if he or she has had diverticulitis (inflammation in parts of the large intestine) or ulcers in his or her stomach or intestines. Some people taking ACTEMRA get tears in their stomach and intestines. This happens most often in people who are also taking nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate. Tell your child’s healthcare provider right away if your child has fever and stomach-area pain that does not go away and a change in his or her bowel habits.

INDICATION AND IMPORTANT SIDE EFFECT INFORMATION
What is ACTEMRA?
ACTEMRA is a prescription medicine called an Interleukin-6 (IL-6) receptor antagonist. ACTEMRA is used to treat:
- Adults with moderately to severely active rheumatoid arthritis (RA) after at least one other medicine called a Disease Modifying Anti-Rheumatic Drug (DMARD) has been used and did not work well.
- People with active polyarticular juvenile idiopathic arthritis (PJIA) ages 2 and above.
- People with active systemic juvenile idiopathic arthritis (SJIA) ages 2 and above.
ACTEMRA is not approved for subcutaneous use in people with PJIA or SJIA.
It is not known if ACTEMRA is safe and effective in children with PJIA or SJIA under 2 years of age or in children with conditions other than PJIA or SJIA.
What is the most important information I should know about ACTEMRA?
ACTEMRA can cause serious side effects including:
1. Serious Infections.
ACTEMRA is a medicine that affects your immune system. ACTEMRA can lower the ability of your immune system to fight infections. Some people have serious infections while taking ACTEMRA, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections.
Your doctor should test you for TB before starting ACTEMRA.
- Your doctor should monitor you closely for signs and symptoms of TB during treatment with ACTEMRA.
You should not start taking ACTEMRA if you have any kind of infection unless your healthcare provider says it is okay.
Before starting ACTEMRA, tell your healthcare provider if you:
- think you have an infection or have symptoms of an infection, with or without a fever, such as:
- sweating or chills
- muscle aches
- shortness of breath
- blood in phlegm
- weight loss
- warm, red, or painful skin or sores on your body
- diarrhea or stomach pain
- burning when you urinate or urinating more often than normal
- feel very tired
- are being treated for an infection
- get a lot of infections or have infections that keep coming back
- have diabetes, HIV, or a weak immune system. People with these conditions have a higher chance for infections.
- have TB, or have been in close contact with someone with TB
- live or have lived, or have traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance for getting certain kinds of fungal infections (histoplasmosis, coccidiomycosis, or blastomycosis). These infections may happen or become more severe if you use ACTEMRA. Ask your healthcare provider, if you do not know if you have lived in an area where these infections are common.
- have or have had hepatitis B
After starting ACTEMRA, call your healthcare provider right away if you have any symptoms of an infection. ACTEMRA can make you more likely to get infections or make worse any infection that you have.
2. Tears (perforation) of the stomach or intestines.
- Tell your healthcare provider if you have had diverticulitis (inflammation in parts of the large intestine) or ulcers in your stomach or intestines. Some people taking ACTEMRA get tears in their stomach or intestine. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate.
- Tell your healthcare provider right away if you have fever and stomach-area pain that does not go away, and a change in your bowel habits.
3. Changes in certain laboratory test results.
Your healthcare provider should do blood tests before you start receiving ACTEMRA, after the first 4 to 8 weeks for rheumatoid arthritis (after which tests should be done every 3 months), every 4 to 8 weeks for PJIA and every 2 to 4 weeks for SJIA during treatment to check for the following side effects of ACTEMRA:
- low neutrophil count. Neutrophils are white blood cells that help the body fight off bacterial infections.
- low platelet count. Platelets are blood cells that help with blood clotting and stop bleeding.
- increase in certain liver function tests.
You should not receive ACTEMRA if your neutrophil or platelet counts are too low or your liver function tests are too high.
Your healthcare provider may stop your ACTEMRA treatment for a period of time or change your dose of medicine if needed because of changes in these blood test results.
- increase in blood cholesterol levels. You may also have changes in other laboratory tests, such as your blood cholesterol levels. Your healthcare provider should do blood tests to check your cholesterol levels 4 to 8 weeks after you start receiving ACTEMRA, and then every 6 months after that.
ACTEMRA may increase your risk of certain cancers by changing the way your immune system works. Tell your healthcare provider if you have ever had any type of cancer.
See “What are the possible side effects with ACTEMRA?” for more information about side effects.
