Last Reviewed by C. H. Weaver M.D., Medical Editor 8/1/2018

Class: Tumor necrosis factor (TNF)-alpha inhibitor

For which conditions is this drug approved? Simponi is approved for use with the medicine methotrexate to treat adults with moderately to severely active rheumatoid arthritis (RA). Simponi is also approved for patients with active psoriatic arthritis, alone or with methotrexate, and for patients with active ankylosing spondylitis.

What is the mechanism of action? Simponi works by blocking the inflammatory effects of a protein called tumor necrosis factor alpha (TNF alpha) in RA and other conditions associated with inflammation. The body produces TNF when there is inflammation. In RA, untreated inflammation can lead to joint damage.

How is Simponi typically given (administered)? Simponi is given as an injection under the skin (subcutaneous injection) one time each month. The injections come in a prefilled syringe or SmartJect® autoinjector. Your doctor may decide you can give the injections to yourself at home of have a caregiver give them. Your doctor will provide training in how to administer home injections.

How are patients typically monitored? Simponi affects your immune system and can lower its ability to fight infections, so your doctor will watch you for signs of infection during treatment, including invasive fungal infections. If you carry the hepatitis B virus, your doctor will monitor you for reactivation of the virus (a risk during treatment with Simponi). Your doctor will also watch for: serious allergic reaction and hypersensitivity, lymphoma and other types of cancer, heart failure, and damage to the protective covering (myelin sheath) surrounding the nervous system.

What are some of the side effects of treatment with Simponi (occur in 10% to 29% of patients)?

  • Upper respiratory infection

This is not a complete list of side effects. Some patients may experience other side effects that are not listed here. Patients may wish to discuss with their physician the other less common side effects of this drug, some of which may be serious.

Some side effects may require medical attention. Other side effects do not require medical attention and may go away during treatment. Patients should check with their physician about any side effects that continue or are bothersome.

What can patients do to help alleviate or prevent discomfort and side effects?

  • Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.
  • Be especially sure to tell your doctor if you use the RA medicines Orencia® (abatacept) or Kineret® (anakinra). You should not receive Simponi while you’re also taking Orencia or Kineret.
  • Tell you doctor if you use other TNF-blocker medicines, including Remicade® (infiiximab), Humira® (adalimumab), Enbrel® (etanercept), or Cimzia® (certolizumab pegol). Also tell your doctor if you receive RA treatment with Rltuxan® (rituximab) or Actemra® (tocilizumab).

  • Do not try to give yourself Simponi injections until your doctor or nurse has shown you how to do it correctly and safely.
  • Try not to miss any doses of Simponi. If you do miss a dose, inject that dose as soon as you remember. Take your next dose at your regular scheduled time.
