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 Results may not be published yet.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 study collects tissue samples like blood, urine, skin, and fat from both healthy volunteers and people with certain conditions. The goal is to give researchers the materials they need to better understand diseases and design future studies. Up to 5,000 adults aged 18 and older will participate, and samples will be coded to protect privacy.

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 provide researchers with valuable tissue samples to better understand diseases and design future studies that may lead to new treatments.
What could go wrong
This is a sample collection study, not a treatment trial. It is designed to support future research, so direct benefits to participants are unlikely.
