In multiple sclerosis, the immune system (the body’s natural defences) attacks and damages the protective insulation around the nerves and the nerves themselves in the brain and spinal cord. The active substance in this medicine, dimethyl fumarate, is thought to work by activating a protein called ‘Nrf2’ that regulates certain genes that produce ‘antioxidants’ involved in protecting cells from damage. Dimethyl fumarate has been shown to reduce inflammation and modulate the activity of the immune system.

Studies on the benefits and risks of the active substance in the authorised use have already been carried out with the reference medicine, Tecfidera, and do not need to be repeated for Dimethyl fumarate Accord.

As for every medicine, the company provided studies on the quality of Dimethyl fumarate Accord. The company also carried out studies that showed that it is ‘bioequivalent’ to the reference medicine. Two medicines are bioequivalent when they produce the same levels of the active substance in the body and are therefore expected to have the same effect.

Because Dimethyl fumarate Accord is a generic medicine and is bioequivalent to the reference medicine, its benefits and risks are taken as being the same as the reference medicine’s.

The European Medicines Agency concluded that, in accordance with EU requirements, Dimethyl fumarate Accord has been shown to have comparable quality and to be bioequivalent to Tecfidera. Therefore, the Agency’s view was that, as for Tecfidera, the benefits of Dimethyl fumarate Accord outweigh the identified risks and it can be authorised for use in the EU.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Dimethyl fumarate Accord have been included in the summary of product characteristics and the package leaflet.

As for all medicines, data on the use of Dimethyl fumarate Accord are continuously monitored. Suspected side effects reported with Dimethyl fumarate Accord are carefully evaluated and any necessary action taken to protect patients.

Dimethyl fumarate Accord received a marketing authorisation valid throughout the EU on 15 February 2023.
