EURneffy® approved as the first needle-free anaphylaxis treatment of adults and children in the UK

Inside Information

ALK (ALKB:DC / OMX: ALK B) today announced that the Medicines and Healthcare Products Regulatory Agency (MHRA) has approved EURneffy^® 2 mg in the United Kingdom (UK) for anaphylaxis treatment of adults and children (≥30 kg). The market launch in the UK is expected within the coming months once market access negotiations are completed.

EURneffy^® (the trade name for neffy^® in the EU and the UK) constitutes the first approved adrenaline nasal spray for timely emergency treatment of allergic reactions (anaphylaxis) and holds the potential to transform the lives of patients with severe allergies in the UK. As Europe’s largest anaphylaxis market, UK represents an important market for ALK.

With an intuitive, needle-free design, EURneffy^® can help more people confidently use adrenaline when it matters most, supporting fast, reliable emergency treatment and ultimately helping improve the chances of successful outcomes and save lives. EURneffy^® offers a longer shelf life (30 months) and superior temperature stability compared to existing adrenaline auto-injectors (AAIs).

Executive Vice President of R&D, Henriette Mersebach (MD), said: “The approval of EURneffy^® 2 mg in the UK introduces an alternative and novel adrenaline treatment option for adult and adolescent patients with life-threatening allergies. EURneffy^® could improve the lives of people with severe allergic reactions and may facilitate that patients and caregivers continually carry adrenaline wherever they go."

The MHRA approval was based on the review of data from the EURneffy^® development programme involving over 700 participants. No serious adverse events were reported in clinical studies with EURneffy^®. The extensive clinical pharmacological data of EURneffy^® 2 mg was comparable to AAIs, with the pharmacodynamics and pharmacokinetics evaluated across a range of dosing conditions.

In Europe, anaphylaxis occurs in up to eight out of every 100,000 people each year, and one in 300 people experiences it at some point in their lives. In emergency situations, uncertainty and hesitation with larger auto-injectors are apparent among those at risk.

neffy^® is developed by US-based ARS Pharmaceuticals, Inc. (“ARS Pharma”). In November 2024, ALK entered into a strategic license agreement with ARS Pharma granting ALK exclusive global rights to commercialise neffy^® (including EURneffy^® in the EU) with exception of the USA, Australia, New Zealand, Japan, and China. In May 2025, the partnership was extended to include a co-promotion agreement in the USA.



The approval does not affect ALK’s financial guidance for 2025.
