Weekly physiologic insulin sessions to improve insulin sensitivity and memory in Alzheimer’s
Official title: Effect of Physiologic Insulin Intervention on Insulin Sensitivity and Cognition
Run by Pennington Biomedical Research Center · NCT07265323 · Data updated 2026-11-12
This trial will test whether weekly short (up to two-hour) physiologic insulin sessions can improve how the body uses glucose and help thinking and memory in adults with Alzheimer’s disease.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with Alzheimer’s disease who have an MMSE score below 25, can attend weekly visits at the Baton Rouge site, and are not pregnant or taking daily benzodiazepines.
✕Probably not a fit
People without impaired insulin sensitivity, those with severe medical conditions that prevent safe insulin administration, or those unable to attend weekly visits are unlikely to gain benefit from this intervention.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults with Alzheimer’s disease will receive a physiologic insulin intervention once a week for six months, with each session lasting up to two hours. Participants will have measures of insulin sensitivity, cognitive testing including the MoCA and the RMBPC, and brain glucose uptake measured by FDG-PET before and after the intervention. Adverse events and feasibility will be tracked throughout the study to determine safety and tolerability. The trial enrolls adults with MMSE scores below 25 and excludes those taking daily benzodiazepines, pregnant women, prisoners, and others judged unsuitable by the investigative team.
Why it matters
Potential benefit: If successful, this approach could improve insulin sensitivity and produce measurable gains in thinking and memory for some people with Alzheimer’s.
How similar studies have gone: Prior studies of insulin for cognition, including intranasal insulin trials, have shown mixed results and this specific weekly physiologic infusion approach is largely novel.
