    Exploring the Nexus of Alzheimer’s Disease and Related Dementias with Cancer and Cancer Therapies
    (Elsevier, 2017-03) Snyder, Heather M.; Ahles, Timothy; Calderwood, Stuart; Carrillo, Maria C.; Chen, Honglei; Chang, Chung-Chou; Craft, Suzanne; De Jager, Philip; Driver, Jane A.; Fillet, Howard; Knopman, David; Lotze, Michael; Tierney, Mary C.; Petanceska, Suzana; Saykin, Andrew; Seshadri, Sudha; Shineman, Diana; Ganguli, Mary; Radiology and Imaging Sciences, School of Medicine
    Recent population studies suggest an intriguing inverse relationship between several types of cancer and neurodegenerative diseases, including Alzheimer’s disease. Understanding the intersection of the underlying biology for these two distinct families of diseases with one another may offer novel approaches to identify new therapeutic approaches and possible opportunities to repurpose existing drug candidates. The Alzheimer’s Association and the Alzheimer’s Drug Discovery Foundation convened a one day workshop to delve into this discussion. Workshop participants outlined research focus areas, potential collaborations and partnerships for future action.

    Unlike familial Alzheimer’s disease, we have been unable to accurately predict symptom onset in presymptomatic familial frontotemporal dementia (f-FTD) mutation carriers, which is a major hurdle to designing disease prevention trials. We developed multimodal models for f-FTD disease progression and estimated clinical trial sample sizes in C9orf72, GRN, and MAPT mutation carriers. Models included longitudinal clinical and neuropsychological scores, regional brain volumes, and plasma neurofilament light chain (NfL) in 796 carriers and 412 non-carrier controls. We found that the temporal ordering of clinical and biomarker progression differed by genotype. In prevention-trial simulations employing model-based patient selection, atrophy and NfL were the best endpoints, whereas clinical measures were potential endpoints in early symptomatic trials. F-FTD prevention trials are feasible but will likely require global recruitment efforts. These disease progression models will facilitate the planning of f-FTD clinical trials, including the selection of optimal endpoints and enrollment criteria to maximize power to detect treatment effects.
