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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether peginterferon alfa-2b injections plus tenofovir alafenamide pills can help adults with HBeAg-negative chronic hepatitis B clear the virus. The trial enrolls 210 previously untreated patients and compares continuous treatment with a pulsed schedule over 48 weeks. The main goal is to see how many participants lose hepatitis B surface antigen, a marker of functional cure.

What this could mean

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

Active substance
Peginterferon alfa-2b combined with tenofovir alafenamide
What this could lead to
If it works, this could offer a path to a functional cure for chronic hepatitis B, letting people stop daily antiviral pills and reducing liver damage risk.
What could go wrong
This is a mid-stage trial, and interferon shots can cause flu-like symptoms, fatigue, and mood changes. Many patients do not clear the virus, and the pulse schedule may prove less effective than continuous treatment.
