Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether drinking whey protein before meals can help adults aged 75-90 with type 2 diabetes keep their blood sugar in a healthy range. Participants will take whey protein or a placebo before each meal for a week, and their blood sugar will be tracked continuously. The goal is to see if this simple dietary change can improve daily glucose control.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
whey protein
What this could lead to
If it works, this could point toward a simple dietary supplement to help older adults with type 2 diabetes manage their blood sugar levels better.
What could go wrong
This is a very small, early-stage trial with only 32 participants. The effect may be small or not apply to everyone. It is not a treatment for diabetes, just a potential aid.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
