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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 Phase 2 trial tests whether adding venetoclax to ibrutinib can improve complete responses in Japanese adults with mantle cell lymphoma that has returned or not responded to treatment. Participants take both oral drugs for about 104 weeks, then continue ibrutinib alone until the disease worsens or side effects become intolerable. The study measures how many people achieve a complete response, meaning no detectable cancer, and also tracks safety and quality of life.

What this could mean

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

Active substance
venetoclax combined with ibrutinib
What this could lead to
If the combination works, it could offer a more effective treatment option for people with mantle cell lymphoma that has returned or stopped responding to prior therapy.
What could go wrong
This is a small, early-phase study with about 12 participants, so results may not apply broadly. The combination may cause side effects, and the added benefit over ibrutinib alone is not yet proven.
