FDA approves Leqembi Iqlik® (lecanemab-irmb) subcutaneous injection as a starting dose for early Alzheimer’s disease

STOCKHOLM, July 13, 2026 /PRNewswire/ -- BioArctic AB's (publ) (Nasdaq Stockholm: BIOA B) partner Eisai today announced that the US Food and Drug Administration (FDA) has approved a supplemental Biologics License Application (sBLA) for a once weekly lecanemab irmb subcutaneous injection (US brand name: Leqembi Iqlik®) as a starting dose for the treatment of early Alzheimer's disease. The US launch is planned for late August 2026.

Leqembi Iqlik is a first-of-its-kind anti-amyloid treatment worldwide, offering at-home dosing for initiation and maintenance. It is administered via an autoinjector, offering a convenient alternative to intravenous (IV) infusion from the start of treatment. For initiation, the approved regimen is 500 mg once weekly, delivered as two 250 mg injections, each administered in approximately 15 seconds.

Leqembi Iqlik is already approved for maintenance dosing in the US at 360 mg once weekly, once 18 months of IV or subcutaneous treatment has been completed. Patients can now receive Leqembi either as an IV infusion or as a subcutaneous injection (SC) with Leqembi Iqlik throughout the entire treatment course – from initiation through maintenance and may switch between administration methods as needed, providing greater flexibility and convenience.
