Shortage information
Tegsedi will be unavailable in the EU as of the end of 2026.
Tegsedi is a medicine used to treat nerve damage caused by hereditary transthyretin amyloidosis (hATTR), a disease in which proteins called amyloids build up in tissues around the body including around the nerves.
It is used in adults in the first two stages of the nerve damage (stage 1, when the patient can walk unaided, and stage 2, when the patient can still walk but needs help).
Tegsedi contains the active substance inotersen.
For further information on the use of the medicine please refer to the medicine’s page.
The company marketing Tegsedi, Akcea Therapeutics Ireland Ltd., is permanently discontinuing the medicine for commercial reasons, in particular low use of the medicine due to the availability of other suitable treatments. The medicine will therefore be unavailable in the EU as of the end of 2026.
The discontinuation is not related to a quality defect of the product or a safety issue.
The discontinuation affects all Member States where the product is marketed: Austria, Bulgaria, France, Germany, Greece, Ireland, Italy, Luxembourg, Poland, Portugal, Spain and Sweden.
For up-to-date information about the status of a medicine shortage in a particular Member State, consult the national shortage register, where available, or contact the national competent authority.
EMA’s Executive Steering Group on Shortages and Safety of Medicinal Products (MSSG) and EMA’s shortages working party (Medicines Shortages Single Point of Contact – SPOC - working party) are closely monitoring the supply situation and engaging with the marketing authorisation holder to mitigate the impact of the supply shortage.
The SPOC Working Party Supports EMA’s MSSG and monitors and reports events that could affect the supply of medicines in the EU.
