What it is for

  • What Usrenty is Usrenty contains the active substance ‘ustekinumab’, a monoclonal antibody. Monoclonal antibodies are proteins that recognise and bind specifically to certain proteins in the body.
  • Usrenty belongs to a group of medicines called ‘immunosuppressants’. These medicines work by weakening part of the immune system.
  • What Usrenty is used for Usrenty is used to treat Moderate to severe Crohn’s disease - in adults.
  • Crohn’s disease is an inflammatory disease of the bowel. If you have Crohn’s disease you will first be given other medicines. If you do not respond well enough or are intolerant to these medicines, you may be given Usrenty to reduce the signs and symptoms of your disease.

How it works

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

Ustekinumab is a human IgG1қ monoclonal antibody that binds with specificity to the p40 protein subunit used by both the IL-12 and IL-23 cytokines.

IL-12 and IL-23 are naturally occurring cytokines that are involved in inflammatory and immune responses, such as natural killer cell activation and CD4+ T-cell differentiation and activation.

From the package leaflet in EMA’s product information, p. 88.

Warnings and precautions

  • Talk to your doctor or pharmacist before using Usrenty. Your doctor will check how well you are before treatment. Make sure you tell your doctor about any illness you have before treatment. Also tell your doctor if you have recently been near anyone who might have tuberculosis. Your doctor will examine you and do a test for tuberculosis, before you have Usrenty. If your doctor thinks you are at risk of tuberculosis, you may be given medicines to treat it.
  • Look out for serious side effects Usrenty can cause serious side effects, including allergic reactions and infections. You must look out for certain signs of illness while you are taking Usrenty. See ‘Serious side effects’ in section 4 for a full list of these side effects.
  • Before you use Usrenty tell your doctor:
  • If you ever had an allergic reaction to Usrenty. Ask your doctor if you are not sure.
  • If you have ever had any type of cancer – this is because immunosuppressants like Usrenty weaken part of the immune system. This may increase the risk of cancer.
  • If you have been treated for psoriasis with other biologic medicines (a medicine produced from a biological source and usually given by injection) – the risk of cancer may be higher.
  • If you have or have had a recent infection or if you have any abnormal skin openings (fistulae).
  • If you have any new or changing lesions within psoriasis areas or on normal skin.
  • If you are having any other treatment for psoriasis and/or psoriatic arthritis – such as another immunosuppressant or phototherapy (when your body is treated with a type of ultraviolet (UV) light). These treatments may also weaken part of the immune system. Using these therapies together with Usrenty has not been studied. However, it is possible it may increase the chance of diseases related to a weaker immune system.
  • If you are having or have ever had injections to treat allergies – it is not known if Usrenty may affect these.
  • If you are 65 years of age or over – you may be more likely to get infections.
  • If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before using Usrenty.
  • Some patients have experienced lupus-like reactions including skin lupus or lupus-like syndrome during treatment with ustekinumab. Talk to your doctor right away if you experience a red, raised, scaly rash sometimes with a darker border, in areas of the skin that are exposed to the sun or with joint pains.
  • Heart attack and strokes Heart attack and strokes have been observed in a study in patients with psoriasis treated with Usrenty.
  • Your doctor will regularly check your risk factors for heart disease and stroke in order to ensure that they are appropriately treated. Seek medical attention right away if you develop chest pain, weakness or abnormal sensation on one side of your body, facial droop, or speech or visual abnormalities.
  • Children and adolescents Usrenty is not recommended for use in children under 18 years of age with Crohn’s disease because it has not been studied in this age group.
  • Other medicines, vaccines and Usrenty Tell your doctor or pharmacist:
  • If you are taking, have recently taken or might take any other medicines.
  • If you have recently had or are going to have a vaccination. Some types of vaccines (live vaccines) should not be given while using Usrenty.
  • If you received Usrenty while pregnant, tell your baby’s doctor about your Usrenty treatment before the baby receives any vaccine, including live vaccines, such as the BCG vaccine (used to prevent tuberculosis). Live vaccines are not recommended for your baby in the first twelve months after birth if you received Usrenty during the pregnancy unless your baby’s doctor recommends otherwise.

From the package leaflet in EMA’s product information, p. 88–89.

Pregnancy and breastfeeding

  • If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
  • A higher risk of birth defects has not been seen in babies exposed to Usrenty in the womb.
  • However, there is limited experience with Usrenty in pregnant women. It is therefore preferable to avoid the use of Usrenty in pregnancy.
  • If you are a woman of childbearing potential, you are advised to avoid becoming pregnant and must use adequate contraception while using Usrenty and for at least 15 weeks after the last Usrenty treatment.
  • Usrenty can pass across the placenta to the unborn baby. If you received Usrenty 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 if you received Usrenty during your pregnancy before the baby receives any vaccine. Live vaccines such as the BCG vaccine (used to prevent tuberculosis) are not recommended for your baby in the first twelve months after birth if you received Usrenty during the pregnancy unless your baby’s doctor recommends otherwise.
  • Ustekinumab may pass into breast milk in very small amounts. Talk to your doctor if you are breast-feeding or are planning to breast-feed. You and your doctor should decide if you should breast-feed or use Usrenty - do not do both.

From the package leaflet in EMA’s product information, p. 90.

Driving and using machines

  • Usrenty has no or negligible influence on the ability to drive and use machines.
  • Usrenty contains sodium This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially ‘sodium- free’. However, before Usrenty is given to you, it is mixed with a solution that contains sodium. Talk to your doctor if you are on a low salt diet.
  • Usrenty contains Polysorbate 80 This medicine contains 10.4 mg of polysorbate 80 (E 433) in each 130 mg/26 mL vial which is equivalent to 0.4 mg/mL (0.6 mg/kg/day). Polysorbates may cause allergic reactions. Tell your doctor if you have any known allergies.
  • 3. How Usrenty will be given Usrenty is intended for use under the guidance and supervision of a doctor experienced in the diagnosis and treatment of Crohn’s disease.
