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 Results may not be published yet.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.

Summary

This observational study will compare nasal immune responses to respiratory viruses like SARS-CoV-2 in 40 adults, including immunocompromised patients and healthy volunteers. Researchers aim to understand how underlying conditions and treatments affect immune cell activity in the nose. The study does not test any treatment but may guide future vaccine or therapy strategies.

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 study could help researchers understand how immune system weaknesses affect protection against respiratory viruses like COVID-19.
What could go wrong
This is a small observational study, not a treatment trial. It may not lead to direct medical advances, and results may not apply to all patients.
