BioArctic

Professor Lars Lannfelt founded BioArctic together with Pär Gellerfors in 2003 to develop an antibody treatment based on Lannfelt's groundbreaking discoveries of the role of amyloid-beta protein in Alzheimer's disease. These discoveries are the basis for lecanemab, an antibody treatment developed in collaboration with the Japanese company Eisai. By binding to specific forms of amyloid-beta, which causes Alzheimer's disease, lecanemab helps to clear amyloid-beta from the brain, thereby altering the course of the disease.

Eisai serves as the lead of lecanemab development and regulatory submissions globally with both Eisai and Biogen co-commercializing and co-promoting the product and Eisai having final decision-making authority. BioArctic has the right to commercialize Leqembi in the Nordic region together with Eisai and the two companies are preparing for a joint commercialization in the region.
