Alzheimer's drug development: What's in the pipeline?

More than 5 million Americans are living with Alzheimer’s disease, and many millions more are eagerly
awaiting new medications to treat it.

We often hear the Alzheimer’s drug development pipeline is dry, but that’s not necessarily true, according to a new report.

“I hear over and over when I give talks around the country, 'There’s nothing going on. There’s no hope. There’s nothing, no progress being made.' When I know that this is an $8 billion industry and
there’s massive amounts of research going on to the tune of 75 drugs in clinical trials right now,” said
Dr. Marwan Sabbagh, lead author of the research and director of Cleveland Clinic Lou Ruvo Center for Brain Health.

Sabbagh said the annual report looks at drugs being developed, how far along they are and how they

Earlier this year, researchers experienced a major setback when a highly anticipated drug targeting amyloid, a type of protein linked to Alzheimer’s that accumulates in the brain, failed.

Sabbagh said while amyloid-targeting drugs aren’t making as much progress as researchers had
hoped, there are new ideas and products moving forward.

For example, more individualized Alzheimer’s treatments based on certain genetic characteristics are

And some scientists are looking at bacteria’s role in Alzheimer’s disease.

Meanwhile, a blood test to potentially detect Alzheimer’s risk is on the horizon, as well.

While we may not have a cure for Alzheimer’s yet, Sabbagh said every discovery helps doctors better understand the disease and leads science in the right direction.

“I know we’re in baseball season now. We’re not going to hit the home run here. We’re going to hit base hits and we’re just going to keep chipping away at this incremental progress,” Sabbagh said. “That’s how we’re going to make this disease something we can manage better.”
