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

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 a chatbot called CoCo can help people understand what they're agreeing to when they join a clinical trial. Researchers want to see if using the chatbot is practical and if it improves comprehension and satisfaction compared to standard remote consent methods. The study involves 100 English-speaking adults who are being considered for enrollment in other research studies.

What this could mean

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

Active substance
CoCo Chatbot, a patient-facing chatbot designed to obtain informed consent
What this could lead to
If successful, this could make informed consent clearer and more satisfying for patients, potentially improving how clinical trials communicate with participants.
What could go wrong
This is a small feasibility study, so results may not apply broadly. The chatbot may not improve comprehension or satisfaction, and there could be technical or usability issues.

Study facts

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

Participants

About 100 people

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

Expected to start

Jan 2027

An estimate. Start dates often move.

Expected to finish

Dec 2031

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.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
