Final Recommendation from Canada's Drug Agency

BioArctic AB's partner Eisai announced that Canada's Drug Agency (CDA-AMC) has issued a final recommendation supporting public reimbursement of Leqembi (lecanemab) for eligible patients in Canada with mild cognitive impairment or mild dementia due to Alzheimer's disease (early AD). The announcement, made on September 1, 2026, marks a milestone for broader access to the treatment in Canada.

The final recommendation follows a reconsideration by CDA-AMC and represents an important step toward broadening access to Leqembi in Canada. Next steps include negotiations through the pan-Canadian Pharmaceutical Alliance, followed by reimbursement decisions by public drug plans across Canada's provinces and territories.

Background on Leqembi

Leqembi is the result of a strategic research alliance between BioArctic and Eisai. It is a humanized immunoglobulin gamma 1 (IgG1) monoclonal antibody directed against aggregated soluble (protofibril) and insoluble forms of amyloid-beta (Aβ). The treatment targets the underlying pathology of Alzheimer's disease rather than just its symptoms.

According to the announcement, Leqembi is approved in 53 countries and is under regulatory review in 6 countries. Following an initial phase with treatment every two weeks for 18 months, intravenous (IV) maintenance dosing with treatment every four weeks is approved in 8 countries, including the United Kingdom, China, the US and Japan, with applications filed in 12 countries and regions. In the US, Leqembi Iqlik is approved for subcutaneous dosing with an autoinjector.

The US FDA approved Eisai's Biologics License Application (BLA) for subcutaneous maintenance dosing with LEQEMBI IQLIK in August 2025. For subcutaneous initiation treatment (500 mg), approval was obtained in the United States in July 2026, and applications are under review in four countries, including Japan and China. In China, the application has been granted Priority Review designation. Since December 2025, lecanemab (IV) has been included in the "Commercial Insurance Innovative Drug List," recently introduced by the National Healthcare Security Administration (NHSA) of China.

Ongoing Clinical Trials

Since July 2020, the Phase 3 clinical study AHEAD 3-45 for individuals with preclinical AD—meaning they are clinically normal and have intermediate or elevated levels of amyloid in their brains—is ongoing. The study is conducted as a public-private partnership between the Alzheimer's Clinical Trial Consortium, funded by the National Institute on Aging, part of the National Institutes of Health, Eisai, and Biogen. Since January 2022, the Tau NexGen clinical study for Dominantly Inherited AD (DIAD) is also ongoing, with lecanemab serving as the backbone anti-amyloid therapy.

Dementia Prevalence in Canada

More than 770,000 people in Canada were estimated to be living with dementia in 2025, and that number is projected to increase to 1.7 million by 2050, according to the announcement. These figures highlight the growing need for effective treatments for Alzheimer's disease in Canada.

BioArctic, a Swedish biopharmaceutical company, noted that the information was released for public disclosure on September 1, 2026, at 07:00 CEST. The press release includes forward-looking statements that involve substantial risks and uncertainties, as is standard for such announcements.
