CMS proposes Medicare coverage policy for Aduhelm for the treatment of Alzheimer’s disease

Jan. 12, 2022

The Centers for Medicare & Medicaid Services (CMS) released a proposed National Coverage Determination (NCD) decision memorandum. Currently, Aduhelm (aducanumab) is the only monoclonal antibody directed against amyloid beta approved by the Food and Drug Administration (FDA) for the treatment of Alzheimer’s disease.

The proposed National Coverage Determination would cover FDA approved monoclonal antibodies that target amyloid for the treatment of Alzheimer’s disease through coverage with evidence development (CED) – which means that FDA-approved drugs in this class would be covered for people with Medicare only if they are enrolled in qualifying clinical trials.

If the proposed National Coverage Determination is finalized, CMS will review each submitted clinical trial to determine whether it meets the criteria specified in the proposed National Coverage Determination. All CMS-approved clinical trials would be posted on the CMS Coverage website.

In addition to CMS-approved trials, National Institutes of Health (NIH) sponsored clinical trials would be covered under this proposed National Coverage Determination as well. Medicare patients participating in these trials would be eligible to receive coverage of the drug, related services, and other routine costs, which may include PET scans if required by a clinical trial protocol.

“This proposed National Coverage Determination is the result of robust evidence analysis conducted through a thorough review process that found while there may be the potential for promise with this treatment, there is also the potential for harm to patients. This harm may range from headaches, dizziness, and falls, to other potentially serious complications such as brain bleeds,” said Dr. Lee Fleisher, CMS Chief Medical Officer and Director of the Center for Clinical Standards and Quality. “We believe that any appropriate assessment of patient health outcomes must weigh both harm and benefit before arriving at a final decision. Therefore, based on the public comments submitted previously and evidence CMS reviewed, the potential for harm, and important questions that remain, we have determined that coverage with evidence development through clinical trials is the right decision for Medicare patients, clinicians, and caregivers, and we look forward to receiving feedback on the proposal.” 

The proposed National Coverage Determination follows an evidence-based analysis CMS initiated in July 2021 to examine whether Medicare will establish a national policy for coverage of monoclonal antibodies directed against amyloid for the treatment of Alzheimer’s disease. During the 2021 national coverage analysis public comment period, CMS held two national listening sessions in which each session was attended by over 360 people, and reviewed 131 public comments and more than 250 relevant peer-reviewed documents.

Currently, in the absence of a national coverage policy, the Medicare Administrative Contractors, which are local contractors that pay Medicare claims, decide whether the drug is covered for a Medicare patient on a claim-by-claim basis.

After reviewing all comments received on the proposed determination, CMS will announce its final decision by April 11, 2022.
