CHICAGO, Jan. 31, 2024 — Despite today’s announcement from Biogen, the Alzheimer’s Association is extremely optimistic about the future of Alzheimer’s treatments; a new era that started with the Food and Drug Administration (FDA) accelerated approval of Aduhelm in 2021.

Approval of Aduhelm was a landmark event for the Alzheimer’s field and, most importantly, provided hope for the millions of people living with early Alzheimer’s, and their families. It was the first FDA-approved treatment to address one of the underlying causes of the disease, not just the symptoms. And the field has continued to advance. 
  • Leqembi is FDA-approved and available now, and is covered by Medicare when the prescribing physician participates in a CMS-approved registry.
  • Donanemab is in review at the FDA; a decision is expected in the coming months.
  • The Alzheimer’s treatment pipeline is robust, with a wide variety of treatment targets being investigated.
The Alzheimer’s Association recommends that people receiving Aduhelm through a clinical trial or by prescription, and their families, should connect with their study contact and/or their personal health care provider to talk through how these changes will impact their treatment and care.

CMS denied Medicare coverage to this treatment — approved by the FDA using the accelerated approval pathway — unless the patient was enrolled in a clinical trial. We believe this contributed to limiting the number of people living with Alzheimer’s, a fatal disease, who could get access to the approved treatment, and created significant confusion for patients and doctors.
