Subcutaneous Leqembi BLA Accepted for Review
FDA has accepted for review an Eisai BLA for Leqembi (lecanemab-irmb) subcutaneous autoinjector weekly maintenance dosing for treating Alzheimer’s disease in patients with mild cognitive impairment or mild dementia stage of disease. The submission is based on data from the Clarity AD (Study 301) open-label extension and “modeling of observed data,” the company says. The agency has set a user fee review action target date of 8/31.
Leqembi was first approved 1/2023 under the accelerated approval pathway, and it was converted to traditional approval 7/2023 following an FDA determination that a confirmatory trial verified clinical benefit. The agency at the time said the drug works by reducing amyloid plaques that form in the brain, which is a “defining pathophysiological feature of the disease.”
