Eisai Starts Rolling BLA for Leqembi Autoinjector

Eisai and Biogen say that Eisai has initiated a rolling submission BLA for lecanemab-irmb (Eisai/Biogen’s Leqembi) subcutaneous autoinjector for weekly maintenance dosing. Leqembi is indicated for treating Alzheimer’s disease in patients with mild cognitive impairment or mild dementia stage of the disease (known as early Alzheimer’s).

An Eisai statement says the BLA is based on data from the Clarity AD study and modeling of observed data.

FDA has granted the autoinjector a fast-track designation.
