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 Results may not be published yet.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

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 looks at 20 people who receive nutrition through a tube at home (parenteral nutrition) at night. Researchers want to see if switching to daytime feeding or adding a small dose of melatonin can fix disrupted body clocks, improve sleep, and boost quality of life for both patients and their caregivers. The study will measure changes in genes, hormones, and sleep patterns over short trial periods.

What this could mean

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

Active substance
melatonin
What this could lead to
If successful, this could point toward simple timing changes or melatonin supplements to improve sleep and well-being for people on home parenteral nutrition.
What could go wrong
This is a very small, early study with only 20 participants. The findings may not apply to everyone, and the benefits of melatonin or timing changes may be minimal or absent.
