About the medicinal product

The medicinal product Defitelio, with the active substance defibrotide, is a concentrate used to make a solution for infusion.

It was authorised for the treatment of a severe veno-occlusive disease of the liver that is also known as sinusoidal obstruction syndrome (impaired circulation in the small veins of the liver). It may be used in patients who are at least one month old.

This veno-occlusive disease affects the liver and is a life-threatening complication of treatments given to prepare the body of patients about to undergo blood stem cell transplantation. This complication can cause the failure of various vital organs and has a fatal outcome in 20 to 30 per cent of patients. The risk is greater in children.

Since this is a rare disease, the medicine has been authorised as an orphan drug. The term "orphan drug" refers to important medicines for rare diseases that meet specific requirements. Medicinal products of this kind benefit from simplified authorisation conditions in Switzerland.

Information on authorisation

The assessment of the clinical data was based on the assessment reports issued by the EMA and the FDA and the corresponding product information texts.

Swissmedic authorised Defitelio in Switzerland on 21 September 2020.

For further information on this authorisation application, Swissmedic would refer readers to the authorisation of the foreign comparator medicinal product.
