Biogen (BIIB) Receives FDA Approval for Weekly Alzheimer's Injection

Biogen and Eisai have received FDA approval for Leqembi Iqlik, a subcutaneous autoinjector for Alzheimer's disease maintenance therapy. The treatment allows for a weekly dose of lecanemab-irmb and is intended for patients with mild cognitive impairment or mild dementia stages of Alzheimer's disease. Biogen's financial health presents a mixed picture, with revenue growth at 2.9% over the past year, but declining operating and gross margins. The company's valuation metrics suggest that the stock may be undervalued. Analysts recommend a moderate buy with a target price of $168.49.

Biogen (NASDAQ: BIIB) and Eisai have received FDA approval for Leqembi Iqlik, a subcutaneous autoinjector designed for maintenance therapy in Alzheimer's disease. The device delivers a weekly dose of lecanemab-irmb, offering an at-home alternative to patients who have completed 18 months of initial intravenous (IV) treatment. This approval marks a significant advancement in Alzheimer's disease management, providing a more accessible and convenient treatment option for patients and caregivers.

Leqembi Iqlik is a subcutaneous autoinjector that can be administered in approximately 15 seconds, compared to the current IV infusion method that requires clinical visits. The device is indicated for maintenance dosing in patients with mild cognitive impairment (MCI) or mild dementia stages of Alzheimer's disease. Clinical trials demonstrated that transitioning to the weekly autoinjector maintained comparable benefits to IV dosing, with an improved safety profile. The device will launch on October 6, 2025, in the U.S., supported by patient assistance programs and dedicated navigators to help with treatment access.

Biogen's financial health presents a mixed picture. Over the past year, the company has seen revenue growth of 2.9%, but operating and gross margins have declined. Analysts recommend a moderate buy with a target price of $168.49, suggesting that the stock may be undervalued.

The FDA approval of Leqembi Iqlik represents a significant advancement in Alzheimer's disease management. The device offers an at-home injection option for patients who have completed initial treatment, improving treatment accessibility and adherence. This development will also reduce healthcare resource utilization by freeing up infusion capacity for new patients while enabling continued treatment for maintenance patients without the burden of regular infusion center visits.
