Today FDA approved Aduhelm (aducanumab) to treat patients with Alzheimer’s disease using the Accelerated Approval pathway, under which the FDA approves a drug for a serious or life-threatening illness that may provide meaningful therapeutic benefit over existing treatments when the drug is shown to have an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit to patients and there remains some uncertainty about the drug’s clinical benefit.

This approval is significant in many ways. Aduhelm is the first novel therapy approved for Alzheimer’s disease since 2003. Perhaps more significantly, Aduhelm is the first treatment directed at the underlying pathophysiology of Alzheimer’s disease, the presence of amyloid beta plaques in the brain.  The clinical trials for Aduhelm were the first to show that a reduction in these plaques—a hallmark finding in the brain of patients with Alzheimer’s—is expected to lead to a reduction in the clinical decline of this devastating form of dementia.

We are well-aware of the attention surrounding this approval. We understand that Aduhelm has garnered the attention of the press, the Alzheimer’s patient community, our elected officials, and other interested stakeholders. With a treatment for a serious, life-threatening disease in the balance, it makes sense that so many people were following the outcome of this review. Further, the data included in the applicant’s submission were highly complex and left residual uncertainties regarding clinical benefit. There has been considerable public debate on whether Aduhelm should be approved. As is often the case when it comes to interpreting scientific data, the expert community has offered differing perspectives.

At the end of the day, we followed our usual course of action when making regulatory decisions in situations where the data are not straightforward. We examined the clinical trial findings with a fine-tooth comb, we solicited input from the Peripheral and Central Nervous System Drugs Advisory Committee, we listened to the perspectives of the patient community, and we reviewed all relevant data. We ultimately decided to use the Accelerated Approval pathway—a pathway intended to provide earlier access to potentially valuable therapies for patients with serious diseases where there is an unmet need, and where there is an expectation of clinical benefit despite some residual uncertainty regarding that benefit. In determining that the application met the requirements for Accelerated Approval, the Agency concluded that the benefits of Aduhelm for patients with Alzheimer’s disease outweighed the risks of the therapy.

In a recent essay published in STAT News, PMC co-director Dr. Jason Karlawish argued that, given aducanumab’s “incomplete and contradictory” data and the results of an analysis of aducanumab’s effectiveness and value by the Institute for Clinical and Economic Review, the FDA should not approve the drug at this time and stated he will not prescribe it to his patients.

Exercise is a key component of maintaining healthy cognitive abilities among older adults. Many studies have shown that physical activity and fitness can lead to improvements in memory retention as well as a reduced risk for cognitive decline.   

The National Institute on Aging (NIA) published an exercise book focused on the methods and benefits of physical exercise for older adults. Titled “Get Fit For Life: Exercise & Physical Activity for Healthy Aging,” the book is available to order or download for free on the NIA website.  

The book is designed for beginners as well as regular exercisers and provides detailed instructions for simple exercises, worksheets to help construct fitness routines, and activity logs. Also included is a special section designated for older adults with chronic conditions such as arthritis, Alzheimer’s disease, and type 2 diabetes. From stretches between TV commercials to yoga routines, the book comes with links to organizations such as the YMCA who have designed exercise programs that build on endurance, mobility, balance, and strength.
