Your watch and grocery list could spot IBD flares early

NCT ID NCT07159776

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 This study
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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 data from a wearable device and grocery loyalty cards can help detect disease flares in people with Crohn's disease or ulcerative colitis. Eighty adults will wear a smartwatch and use a store card to track their health and food purchases. The goal is to develop digital markers that signal worsening disease without extra clinic visits.

What this could mean

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

What this could lead to
If successful, this could lead to a way to detect IBD flares early using everyday data like heart rate and grocery purchases, helping doctors adjust treatment sooner.
What could go wrong
This is an early observational study with only 80 participants. The digital signals may not reliably predict flares, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

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

Who is studied

This is an open label observational trial with partially blinded data collection (wearable and shopping data blinded for the patient and treating HCP). Patients in the study will not be randomized. Patients will be recruited via planned outpatient visits and day clinic admissions. Patients will be allocated to one of the three target patient groups at the investigator's discretion. 1. Patients with IBD in longstanding remission (\>2 years) (maximum of 20 patients) 2. Patients with IBD recent event (diagnosis or flare of IBD) (\<1year) (minimum 20 patients) 3. Additional patients with IBD in standard follow up. From the moment 60 patients are included, no additional patients can be recruited in group 1 or 3 prior to completion of group 2.
