The Worldwide Alzheimer's Disease Neuroimaging Initiative: ADNI-3 updates and global perspectives.

The Worldwide Alzheimer's Disease Neuroimaging Initiative (WW-ADNI) is a collaborative effort to investigate imaging and biofluid markers that can inform Alzheimer's disease treatment trials. It is a public-private partnership that spans North America, Argentina, Australia, Canada, China, Japan, Korea, Mexico, and Taiwan. In 2004, ADNI researchers began a naturalistic, longitudinal study that continues today around the globe. Through several successive phases (ADNI-1, ADNI-GO, ADNI-2, and ADNI-3), the study has fueled amyloid and tau phenotyping and refined neuroimaging methodologies. WW-ADNI researchers have successfully standardized analyses and openly share data without embargo, providing a rich data set for other investigators. On August 26, 2020, the Alzheimer's Association convened WW-ADNI researchers who shared updates from ADNI-3 and their vision for ADNI-4.
Competing Interests: WJ has served as a consultant to Bioclinica, Biogen, CuraSen, Grifols, and Roche/Genentech. CRJ serves on an independent data monitoring board for Roche, has served as a speaker for Eisai, and consulted for Biogen, but he receives no personal compensation from any commercial entity. He receives research support from NIH, the GHR Foundation, and the Alexander Family Alzheimer's Disease Research Professorship of the Mayo Clinic. AJS and the Indiana University ADRC receives in‐kind PET precursor support from Avid Radiopharmaceuticals, a subsidiary of Eli Lilly. CS is a full‐time employee of Merck and Co., Inc. and owns shares in the company. CCR has received institutional research grants from Cerveau Technologies, Biogen, Eisai, Abbvie, Roche, and Janssen, and is also participating in Scientific Advisory Boards for Cerveau Technologies and Biogen Australia. LMS is supported by the NIA ADNI‐3 grant for which he provides QC oversight for CSF analyses using the Roche Elecsys automated platform and reagents, and has also received IIS grant support for AD biomarker studies from Roche.
