Bill Gates, the second-richest man in the world, is already backing an effort to build better ways to diagnose and track Alzheimer’s disease. Now, he's helped sign on the world's richest man to back the effort as well. With new support from Amazon founder Jeff Bezos and other donors, the Diagnostic Accelerator "venture philanthropy" project at the Alzheimer's Drug Discovery Foundation (ADDF) is poised to name its first grantees in the near future and has begun taking applications for a second round of grants focused on fast-tracking digital tools for the disease and its related dementias. The accelerator fund launched last July with plans to deliver nearly $35 million in grants over three years for the development of new clinical biomarkers and tests. With the additions of Bezos and his wife MacKenzie, plus other funding commitments, that total has now grown to nearly $50 million. Virtual Clinical Trials Online This virtual event will bring together industry experts to discuss the increasing pace of pharmaceutical innovation, the need to maintain data quality and integrity as new technologies are implemented and understand regulatory challenges to ensure compliance. “It’s hard to overstate how important finding a reliable, affordable, and easy-to-use diagnostic is for stopping Alzheimer’s,” Gates wrote in a post on his blog, pointing to technologies on the horizon that could involve simple blood tests or analyses of voice recordings to spot early signs of the disease.

Gates highlighted work by Boston University researcher Rhoda Au, who heads up neuropsychology work for the decades-long Framingham Heart Study that has gathered thousands of audio recordings of its participants spanning several years, including patients that eventually developed Alzheimer’s disease. “There’s a lot going on when you speak,” Gates wrote. “The whole assembly process of how you string words together and form sentences is complicated.” “If you could use a computer to analyze how an Alzheimer’s patient speaks over the years, you might be able to pick up on subtle changes—and then look for those same patterns in younger patients who show no other signs of the disease,” he added, but noted the work is still in its early stages and researchers aren’t yet sure which speech patterns to look for.

By expanding its work into digital biomarkers such as audio analyses and other cognitive assessments, the ADDF hopes to augment traditional, wet laboratory tests and imaging tools with more cost-effective or remotely accessible approaches used in both clinical research and general practice. “This real-world evidence has the potential to add significant value to clinical trials, increasing patient engagement, enhancing monitoring, and greatly improving treatment outcomes,” Fillit said.
The Diagnostic Accelerator project at the Alzheimer's Drug Discovery Foundation is set to welcome Amazon founder Jeff Bezos as one of its backers. Bezos joins Bill Gates and other donors in supporting the “venture philanthropy” fund, which was launched in July 2018 to provide grants for the development of digital tools to diagnose and track Alzheimer’s disease. The fund has exceeded its original $close to $50mm target and has now reached 35.
