Aducanumab: The Beginning of the End of Alzheimer’s Disease?

Jason Karlawish, MD, writes in STAT:

In histories written about Alzheimer’s disease, 2019 will turn up as a landmark year, one in which researchers, clinicians, patients, and their families were whipsawed from crushing despair to giddy optimism.

The year unfolded with a string of disappointments. One of the biggest came on March 21 when Boston-based Biogen announced it had pulled the plug on two clinical trials of aducanumab, a promising treatment for individuals with Alzheimer’s disease. The drug had failed a “futility analysis,” meaning it would not be able to achieve its objectives. More bad news came in the weeks and months to follow. An entire class of drugs called BACE inhibitors (pronounced “base” as in baseball) had failed.

By the annual international meeting of Alzheimer’s investigators in Los Angeles in July, a pervasive disappointment was enmeshed with embarrassment, heightened by the meeting’s timing on the 50th anniversary of the successful Apollo mission to the moon. A half a century ago, we were able to send someone to the moon, have him walk about, and return home but, despite all our time and effort and money since then, despite all the advances in genomics, proteomics, and other “omics,” despite precision medicine, we haven’t been able to make a dent in this disease.
