Alzheimer’s Disease Interception: Methods for Evaluating a New Generation of Therapies

Building on a 2013 GPC guidance document, this initiative provides updated guidance on methods for evaluating the efficacy of therapies to treat Alzheimer's disease.


The field of Alzheimer’s therapeutics has rapidly progressed over the past few years to focus increasingly on earlier stages of disease and on disease interception. This new focus raised issues regarding the types of evidence needed by health plan decision-makers to cover these new therapies. How can study designers assure that patients are correctly identified as candidates for therapy? How long should patients be followed to demonstrate benefit?

This initiative involved a broad, multi-stakeholder group of participants. Representatives from the following organizations participated:

  • Pfizer Innovative Health
  • Alzheimer’s Drug Discovery Foundation
  • Center for Alzheimer's Care, The University of Utah
  • FDA
  • High Lantern Group
  • Aetna
  • Faegre Baker Daniels Consulting
  • University of Utah Health Care
  • NIH/NIA
  • Johns Hopkins School of Medicine
  • United Healthcare
  • Alzheimer Disease Research Center, Icahn School of Medicine at Mt. Sinai
  • Keck School of Medicine, University of Southern California
  • Alzheimer's Foundation of America
  • Beating Alzheimer's by Embracing Science
  • UsAgainstAlzheimer's
  • GNS Healthcare, Inc.

The findings and recommendations are available in the report: "Designing Late Phase Clinical Trials of Disease-modifying Agents to Delay or Prevent Dementia due to Alzheimer’s Disease", November, 2018.
