What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests whether daily consumption of freeze-dried grape powder can improve immune function and reduce inflammation in healthy adults aged 50 to 75. Participants will drink a grape powder beverage or a placebo for four weeks each, while avoiding grapes and other polyphenol-rich foods. Researchers will measure immune markers and inflammatory responses from blood samples to see if grapes can positively influence age-related changes in immunity.

What this could mean

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

Active substance
Freeze-dried whole grape powder
What this could lead to
If it works, this could point toward a simple dietary addition that supports immune health and reduces inflammation in older adults.
What could go wrong
This is a small, early-stage study, and the effects may be modest or not translate to real-world benefits. Participants must avoid grapes and other polyphenol-rich foods, which may be challenging.
