Opinion

EMA has issued an opinion on this medicine

Lecanemab

Overview

On 14 November 2024, the Committee for Medicinal Products for Human Use (CHMP), following a re-examination procedure, adopted a positive opinion, recommending the granting of a marketing authorisation for the medicinal product Leqembi, intended for the treatment of early Alzheimer’s disease in apolipoprotein E ε4 (ApoE ε4) non-carriers or heterozygotes. The applicant for this medicinal product is Eisai GmbH.

Leqembi will be available as a 100 mg/ml concentrate for solution for infusion. The active substance of Leqembi is lecanemab, a monoclonal antibody (ATC code: N06DX04) that binds to aggregated soluble and insoluble forms of amyloid beta and, by doing so, reduces beta plaques.

The benefit of Leqembi is a reduced progression of the cognitive and functional deficits associated with Alzheimer’s disease. The most common side effects are amyloid-related imaging abnormalities.

The full indication is:

Leqembi is indicated for the treatment of adult patients with a clinical diagnosis of mild cognitive impairment and mild dementia due to Alzheimer’s disease (Early Alzheimer’s disease) who are apolipoprotein E ε4 (ApoE ε4) non-carriers or heterozygotes with confirmed amyloid pathology (see section 4.4).

Treatment should be initiated and supervised by physicians experienced in the diagnosis and treatment of Alzheimer’s disease with timely access to magnetic resonance imaging (MRI). Leqembi infusions should be administered by qualified healthcare professionals trained to monitor for, recognize and manage infusion-related reactions. Leqembi will only be prescribed in the context of controlled access programmes.

Detailed recommendations for the use of this product will be described in the summary of product characteristics (SmPC), which will be published in the European public assessment report (EPAR) and made available in all official European Union languages after the marketing authorisation has been granted by the European Commission.
