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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study compares two antiviral strategies—one using a single drug (TAF) and the other starting with two drugs (entecavir plus TAF) then switching to TAF alone—in 120 people with advanced hepatitis B-related liver cancer who are also receiving immunotherapy. The main goal is to see which approach leads to better survival at 24 months. Researchers will also track virus levels and liver function over time.

What this could mean

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

Active substance
Tenofovir alafenamide (TAF) and entecavir (ETV)
What this could lead to
If successful, this could show that combining two antivirals before switching to one helps people with hepatitis B-related liver cancer live longer during immunotherapy.
What could go wrong
This is a small, early-stage study with only 120 participants, so results may not apply to everyone. The trial hasn't started yet, and it's unclear if one strategy is truly better.

Participants

About 120 people

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

Expected to start

Expected to finish

Sep 2028

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.
