What it is for

Yuflyma is intended for the treatment of the following inflammatory diseases:

  • Yuflyma contains the active substance adalimumab, a medicine that acts on your body’s immune (defence)
  • system.
  • Rheumatoid arthritis
  • Polyarticular juvenile idiopathic arthritis
  • Enthesitis-related arthritis
  • Ankylosing spondylitis
  • Axial spondyloarthritis without radiographic evidence of ankylosing spondylitis
  • Psoriatic arthritis
  • Plaque psoriasis
  • Hidradenitis suppurativa
  • Crohn’s disease
  • Ulcerative colitis
  • Non-infectious uveitis The active ingredient in Yuflyma, adalimumab, is a human monoclonal antibody. Monoclonal antibodies are proteins that attach to a specific target in the body.
  • The target of adalimumab is a protein called tumour necrosis factor (TNFα), which is involved in the immune (defence) system and is present at increased levels in the inflammatory diseases listed above. By attaching to TNFα, Yuflyma decreases the process of inflammation in these diseases.
  • Rheumatoid arthritis Rheumatoid arthritis is an inflammatory disease of the joints.
  • Yuflyma is used to treat moderate to severe rheumatoid arthritis in adults. You may first be given other disease-modifying medicines, such as methotrexate. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Yuflyma can also be used to treat severe, active and progressive rheumatoid arthritis without previous methotrexate treatment.
  • Yuflyma can slow down the damage to the joints caused by the inflammatory disease and can help them move more freely.
  • Your doctor will decide if Yuflyma should be used with methotrexate or alone.
  • Polyarticular juvenile idiopathic arthritis Polyarticular juvenile idiopathic arthritis is an inflammatory disease of the joints.
  • Yuflyma is used to treat polyarticular juvenile idiopathic arthritis in patients from 2 years of age. You may first be given other disease-modifying medicines, such as methotrexate. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Your doctor will decide if Yuflyma should be used with methotrexate or alone.
  • Enthesitis-related arthritis Enthesitis-related arthritis is an inflammatory disease of the joints and the places where tendons join the bone.
  • Yuflyma is used to treat enthesitis-related arthritis in patients from 6 years of age. You may first be given other disease-modifying medicines, such as methotrexate. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Ankylosing spondylitis and axial spondyloarthritis without radiographic evidence of ankylosing spondylitis Ankylosing spondylitis and axial spondyloarthritis without radiographic evidence of ankylosing spondylitis are inflammatory diseases of the spine.
  • Yuflyma is used to treat severe ankylosing spondylitis and axial spondyloarthritis without radiographic evidence of ankylosing spondylitis in adults. You may first be given other medicines. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Psoriatic arthritis Psoriatic arthritis is an inflammatory disease of the joints that is usually associated with psoriasis.
  • Yuflyma is used to treat psoriatic arthritis in adults. Yuflyma can slow down the damage to the joints caused by the disease and can help them move more freely. You may first be given other medicines. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Plaque psoriasis Plaque psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales.
  • Plaque psoriasis can also affect the nails, causing them to crumble, become thickened and lift away from the nail bed which can be painful.
  • Yuflyma is used to treat
  • moderate to severe chronic plaque psoriasis in adults and
  • severe chronic plaque psoriasis in children and adolescents aged 4 to 17 years for whom topical therapy and phototherapies have either not worked very well or are not suitable.
  • Hidradenitis suppurativa Hidradenitis suppurativa (sometimes called acne inversa) is a chronic and often painful inflammatory skin disease. Symptoms may include tender nodules (lumps) and abscesses (boils) that may leak pus. It most commonly affects specific areas of the skin, such as under the breasts, the armpits, inner thighs, groin and buttocks. Scarring may also occur in affected areas.
  • Yuflyma is used to treat
  • moderate to severe hidradenitis suppurativa in adults and
  • moderate to severe hidradenitis suppurativa in adolescents aged 12 to 17 years.
  • Yuflyma can reduce the number of nodules and abscesses caused by the disease and the pain that is often associated with the disease. You may first be given other medicines. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Crohn’s disease Crohn’s disease is an inflammatory disease of the digestive tract.
  • Yuflyma is used to treat
  • moderate to severe Crohn’s disease in adults and
  • moderate to severe Crohn’s disease in children and adolescents aged 6 to 17 years.
  • You may first be given other medicines. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Ulcerative colitis Ulcerative colitis is an inflammatory disease of the large intestine.
  • Yuflyma is used to treat
  • moderate to severe ulcerative colitis in adults and
  • moderate to severe ulcerative colitis in children and adolescents aged 6 to 17 years.
  • You may first be given other medicines. If you do not respond well enough to these medicines, you will be given Yuflyma.
  • Non-infectious uveitis Non-infectious uveitis is an inflammatory disease affecting certain parts of the eye.
  • Yuflyma is used to treat
  • adults with non-infectious uveitis with inflammation affecting the back of the eye
  • children with chronic non-infectious uveitis from 2 years of age with inflammation affecting the front of the eye.
  • This inflammation may lead to a decrease of vision and/or the presence of floaters in the eye (black dots or wispy lines that move across the field of vision). Yuflyma works by reducing this inflammation.
  • You may first be given other medicines. If you do not respond well enough to these medicines, you will be given Yuflyma.

How it works

From the US prescribing label for the same active substance (Adalimumab-aacf). It describes the substance, not this exact product.

Adalimumab products bind specifically to TNF-alpha and block its interaction with the p55 and p75 cell surface TNF receptors.

Adalimumab products also lyse surface TNF expressing cells in vitro in the presence of complement.

Warnings and precautions

  • Talk to your doctor or pharmacist before using Yuflyma.
  • Allergic reactions
  • If you get allergic reactions with symptoms such as chest tightness, wheezing, dizziness, swelling or rash do not inject more Yuflyma and contact your doctor immediately since, in rare cases, these reactions can be life threatening.
  • Infections
  • If you have an infection, including long-term infection or an infection in one part of the body (for example, leg ulcer) consult your doctor before starting Yuflyma. If you are unsure, contact your doctor.
  • You might get infections more easily while you are receiving Yuflyma treatment. This risk may increase if you have problems with your lungs. These infections may be serious and include:
  • tuberculosis
  • infections caused by viruses, fungi, parasites or bacteria
  • severe infection in the blood (sepsis)
  • In rare cases, these infections can be life-threatening. It is important to tell your doctor if you get symptoms such as fever, wounds, feeling tired or dental problems. Your doctor may tell you to stop using Yuflyma for some time.
  • Tell your doctor if you live or travel in regions where fungal infections (for example, histoplasmosis, coccidioidomycosis or blastomycosis) are very common.
  • Tell your doctor if you have had infections which keep coming back or other conditions that increase the risk of infections.
  • If you are over 65 years you may be more likely to get infections while taking Yuflyma. You and your doctor should pay special attention to signs of infection while you are being treated with Yuflyma. It is important to tell your doctor if you get symptoms of infections, such as fever, wounds, feeling tired or dental problems.
  • Tuberculosis
  • It is very important that you tell your doctor if you have ever had tuberculosis, or if you have been in close contact with someone who has had tuberculosis. If you have active tuberculosis, do not use Yuflyma.
  • As cases of tuberculosis have been reported in patients treated with Yuflyma, your doctor will check you for signs and symptoms of tuberculosis before starting Yuflyma. This will include a thorough medical evaluation including your medical history and appropriate screening tests (for example, chest X-ray and a tuberculin test). The conduct and results of these tests should be recorded on your Patient Reminder Card.
  • Tuberculosis can develop during therapy even if you have received treatment for the prevention of tuberculosis.
  • If symptoms of tuberculosis (for example, cough that does not go away, weight loss, lack of energy, mild fever), or any other infection appear during or after therapy tell your doctor immediately.
  • Hepatitis B
  • Tell your doctor if you are a carrier of the hepatitis B virus (HBV), if you have active HBV or if you think you might be at risk of getting HBV.
  • Your doctor should test you for HBV. In people who carry HBV, Yuflyma can cause the virus to become active again.
  • In some rare cases, especially if you are taking other medicines that suppress the immune system, reactivation of HBV can be life-threatening.
  • Surgery or dental procedure
  • If you are about to have surgery or dental procedures, please inform your doctor that you are taking Yuflyma. Your doctor may recommend temporary discontinuation of Yuflyma.
  • Demyelinating disease
  • If you have or develop a demyelinating disease (a disease that affects the insulating layer around the nerves, such as multiple sclerosis), your doctor will decide if you should receive or continue to receive Yuflyma. Tell your doctor immediately if you experience symptoms like changes in your vision, weakness in your arms or legs or numbness or tingling in any part of your body.
  • Vaccinations
  • Certain vaccines may cause infections and should not be given while receiving Yuflyma.
  • Check with your doctor before you receive any vaccines.
  • It is recommended that children, if possible, be given all the scheduled vaccinations for their age before they start treatment with Yuflyma.
  • If you received Yuflyma while you were pregnant, your baby may be at higher risk for getting such an infection for up to approximately five months after the last Yuflyma dose you received during pregnancy. It is important that you tell your baby's doctors and other health care professionals about your Yuflyma use during your pregnancy so they can decide when your baby should receive any vaccine.
  • Heart failure
  • If you have mild heart failure and are being treated with Yuflyma, your heart failure status must be closely monitored by your doctor. It is important to tell your doctor if you have had or have a serious heart condition. If you develop new or worsening symptoms of heart failure (e.g. shortness of breath, or swelling of your feet), you must contact your doctor immediately. Your doctor will decide if you should receive Yuflyma.
  • Fever, bruising, bleeding or looking pale
  • In some patients the body may fail to produce enough of the blood cells that fight off infections or help you to stop bleeding. Your doctor may decide to stop treatment. If you develop a fever that does not go away, develop light bruises or bleed very easily or look very pale, call your doctor right away.
  • Cancer
  • There have been very rare cases of certain kinds of cancer in children and adult patients taking Yuflyma or other TNF blockers.
  • People with more serious rheumatoid arthritis that have had the disease for a long time may have a higher than average risk of getting lymphoma (a cancer that affects the lymph system) and leukaemia (a cancer that affects the blood and bone marrow).
  • If you take Yuflyma the risk of getting lymphoma, leukaemia, or other cancers may increase. On rare occasions, an uncommon and severe type of lymphoma, has been seen in patients taking Yuflyma. Some of those patients were also treated with azathioprine or 6- mercaptopurine.
  • Tell your doctor if you are taking azathioprine or 6-mercaptopurine with Yuflyma.
  • Cases of non-melanoma skin cancer have been observed in patients taking Yuflyma.
  • If new skin lesions appear during or after therapy or if existing lesions change appearance, tell your doctor.
  • There have been cases of cancers, other than lymphoma in patients with a specific type of lung disease called Chronic Obstructive Pulmonary Disease (COPD) treated with another TNF blocker. If you have COPD, or are a heavy smoker, you should discuss with your doctor whether treatment with a TNF blocker is appropriate for you.
  • Autoimmune disease
  • On rare occasions, treatment with Yuflyma could result in lupus-like syndrome. Contact your doctor if symptoms such as persistent unexplained rash, fever, joint pain or tiredness occur.
  • Children and adolescents
  • Vaccinations: if possible, children should be up to date with all vaccinations before using Yuflyma.

From the package leaflet in EMA’s product information, p. 177–179.

Pregnancy and breastfeeding

  • You should consider the use of adequate contraception to prevent pregnancy and continue its use for at least 5 months after the last Yuflyma treatment.
  • If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice about taking this medicine.
  • Yuflyma should only be used during a pregnancy if needed.
  • According to a pregnancy study, there was no higher risk of birth defects when the mother had received Yuflyma during pregnancy compared with mothers with the same disease who did not receive Yuflyma.
  • Yuflyma can be used during breast-feeding.
  • If you receive Yuflyma during your pregnancy, your baby may have a higher risk for getting an infection.
  • It is important that you tell your baby’s doctors and other health care professionals about your Yuflyma use during your pregnancy before the baby receives any vaccine. For more information on vaccines see the “Warnings and precautions” section.

From the package leaflet in EMA’s product information, p. 180.

Other medicines

  • Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. You should not take Yuflyma with medicines containing the following active substances due to increased risk of serious infection:
  • anakinra
  • abatacept.
  • Yuflyma can be taken together with:
  • methotrexate
  • certain disease-modifying anti-rheumatic agents (for example, sulfasalazine, hydroxychloroquine, leflunomide and injectable gold preparations)
  • steroids or pain medications including non-steroidal anti-inflammatory drugs (NSAIDs).
  • If you have questions, please ask your doctor.

From the package leaflet in EMA’s product information, p. 179–180.

  • When needed (for example when you are travelling), a single Yuflyma pre-filled syringe with needle guard may be stored at room temperature (up to 25°C) for a maximum period of 31 days – be sure to protect it from light. Once removed from the refrigerator for room temperature storage, the syringe must be used within 31 days or discarded, even if it is returned to the refrigerator.
  • You should record the date when the syringe is first removed from refrigerator and the date after which it should be discarded.
  • Do not throw away any medicines via wastewater or household waste. Ask your doctor or pharmacist how to throw away medicines you no longer use. These measures will help protect the environment.
