abstract = {Background: The 2017 Alzheimer's disease (AD) Strategic
Biomarker Roadmap (SBR) structured the validation of AD
diagnostic biomarkers into 5 phases, systematically
assessing analytical validity (Phases 1-2), clinical
validity (Phases 3-4), and clinical utility (Phase 5)
through primary and secondary Aims. This framework allows to
map knowledge gaps and research priorities, accelerating the
route towards clinical implementation. Within an initiative
aimed to assess the development of biomarkers of tau
pathology, we revised this methodology consistently with
progress in AD research.Methods: We critically appraised the
adequacy of the 2017 Biomarker Roadmap within current
diagnostic frameworks, discussed updates at a workshop
convening the Alzheimer's Association and 8 leading AD
biomarker research groups, and detailed the methods to allow
consistent assessment of aims achievement for tau and other
AD diagnostic biomarkers.Results: The 2020 update applies to
all AD diagnostic biomarkers. In Phases 2-3, we admitted a
greater variety of study designs (e.g., cross-sectional in
addition to longitudinal) and reference standards (e.g.,
biomarker confirmation in addition to clinical progression)
based on construct (in addition to criterion) validity. We
structured a systematic data extraction to enable
transparent and formal evidence assessment procedures.
Finally, we have clarified issues that need to be addressed
to generate data eligible to evidence-to-decision
procedures.Discussion: This revision allows for more
versatile and precise assessment of existing evidence, keeps
up with theoretical developments, and helps clinical
researchers in producing evidence suitable for
evidence-to-decision procedures. Compliance with this
methodology is essential to implement AD biomarkers
efficiently in clinical research and diagnostics.Keywords:
