NCT ID NCT05562492

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a hybrid closed-loop system (CamAPS FX) can improve blood sugar control in people aged 16 and older with cystic fibrosis-related diabetes. The system combines an insulin pump, continuous glucose monitor, and smartphone app to automatically adjust insulin. Over 26 weeks, researchers will compare this approach to standard insulin therapy with glucose monitoring in 128 participants.

What this could mean

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

Active substance
CamAPS FX hybrid closed-loop system (insulin pump, continuous glucose monitor, and smartphone app)
What this could lead to
If successful, this could offer a more automated and effective way to manage blood sugar in cystic fibrosis-related diabetes, potentially reducing complications and improving quality of life.
What could go wrong
This is a relatively small, early-stage trial (128 participants) and the technology may not work for everyone. There are risks of device malfunction or hypoglycemia, and the system requires 24/7 wear and training.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 128 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2023

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

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.
