Academic Distinctions
Dr. Grill has been the recipient of the National Alzheimer’s Coordinating Center Junior Investigator Award, the Alzheimer’s Association Turken Research Prize, the Community Spirit Award from OPICA Adult Day Services, and the P. Gene and Elaine Smith Term Chair in Alzheimer’s Disease Research. He has been funded by the National Institute on Aging, the National Institute of Neurological Disorders and Stroke, the Alzheimer’s Association, the BrightFocus Foundation, the Hartford Foundation, the American Federation for Aging Research, and the University of California. He is the co-leader of the Internal Ethics Committee and the Recruitment Unit for the NIA-funded Alzheimer's Clinical Trial Consortium. He is the Chair of the Internal Ethics Committee for the Alzheimer’s Disease Cooperative Study. He is a member of the Scientific Advisory Board for Maria Shriver’s Women’s Alzheimer’s Movement and for HFC (formerly Hilarity for Charity). In 2017, he co-chaired a workgroup as part of the NIH’s Inclusion Across the Lifespan workshop, a congressional mandate in the 21st Century Cures Act (P.L. 114-255). He is part of a working group sponsored by the National Institute on Aging and the Alzheimer’s Association charged with creating a national strategy for recruitment to Alzheimer’s disease clinical research. In 2021, he was an invited presenter and contributor to "A Workshop on Biomarkers and Other Pre-Clinical Diagnostics of Alzheimer's Disease," sponsored by the National Institute on Aging and convened by the National Academies of Science, Engineering, and Medicine.
Research Abstract
For any new Alzheimer’s disease drug to achieve FDA approval and widespread clinical use, it must be tested in human beings and demonstrated as both safe and efficacious. Studies to test the safety and efficacy of new treatments are called clinical trials. Clinical testing now represents the most costly and difficult phase of developing improved therapies. A major challenge of completing human clinical trials is the timely enrollment of participants who will enable adequate examination of therapeutic hypotheses. Alzheimer’s disease clinical trials now enroll people with Alzheimer’s dementia, people with mild cognitive impairment, and people with healthy memories but who are at increased risk to some day develop dementia. We are engaged in a variety of studies that aim to
• Identify means to improve Alzheimer’s disease clinical trial designs to enable adequate testing in fewer participants,
• Elucidate barriers to clinical trial enrollment in each Alzheimer’s disease population, so that trials and recruitment campaigns can be designed in a manner that maximizes the speed of accrual,
• Understand better which participants are at risk to be lost to follow-up, to guide clinician scientists when enrolling participants in Alzheimer’s disease trials, and
• Investigate the ethical challenges in clinical trials, especially those related to Alzheimer’s disease disclosure, including the disclosure of diagnosis, biomarker results, and genetic testing.
