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
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
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

Summary

This study tested a drug called tislelizumab, which helps the immune system fight cancer, against standard chemotherapy in people with Hodgkin lymphoma that returned or didn't respond to treatment. Only 3 people took part before the study was stopped early. Because of this, we don't have enough information to know if tislelizumab works better or is safer than chemotherapy.

What this could mean

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

Active substance
Tislelizumab (a type of immunotherapy that helps the immune system attack cancer cells)
What this could lead to
If it works, this could offer a new treatment option for people with Hodgkin lymphoma that hasn't responded to other therapies.
What could go wrong
The trial was terminated early with only 3 participants, so we have very little data. It's unclear if tislelizumab is effective or safe compared to standard chemotherapy.
