NCT03757910

Brief Summary

This is a cross-sectional pilot study of Alzheimer's disease (AD) brain imaging biomarkers in Diabetes Prevention Program (DPP) outcomes study (DPPOS) participants from the New York City sites (Columbia and Einstein), comparing 10 persons originally randomized to metformin and 10 persons randomized to placebo in DPP. All study procedures will be conducted at Columbia University Irving Medical Center. Eligible participants will receive a PET scans and a brain MRI, which may be conducted in one, two, or three separate visits.

Outcome Measures

Primary Outcomes (2)

  • Brain Amyloid SUVR

    Whole brain amyloid (11C-PIB) standardized uptake volume ratio (SUVR)

    Up to 1 hour post-injection

  • Brain Tau SUVR

    Tau (18F-MK-6240) SUVR in medial and inferior temporal lobes

    Up to 1 hour post-injection

Secondary Outcomes (2)

  • Hippocampal Cortical Thickness

    Up to 1 hour post-injection

  • White Matter Hyper Intensity Volume

    Up to 1 hour post-injection

Study Arms (2)

DPPOS Exposed to Metformin

EXPERIMENTAL

DPPOS participants with exposure to metformin will be scanned with 18F-MK-6240 and 11C-PIB.

Drug: 18F-MK-6240Drug: 11C-PIB

DPPOS Exposed to Placebo

ACTIVE COMPARATOR

DPPOS participants with no exposure to metformin but only placebo will be scanned with 18F-MK-6240 and 11C-PIB.

Drug: 18F-MK-6240Drug: 11C-PIB

Interventions

This radiotracer will be used to detect Tau.The injected activity will equal 5 millicuries (mCi).

DPPOS Exposed to MetforminDPPOS Exposed to Placebo

This radiotracer will be used to detect amyloid. Participants will be injected with an intravenous bolus of up to 5-15 mCi.
