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 Results may not be published yet.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.

Summary

This study tests the safety and best dose of loncastuximab tesirine, a targeted antibody-drug conjugate, in people with relapsed or refractory diffuse large B-cell lymphoma or high-grade B-cell lymphoma who also have moderate or severe liver impairment. The goal is to find a dosing regimen that works for these patients, who are often excluded from clinical trials. Only 5 participants are enrolled in this early-stage, open-label study.

What this could mean

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

Active substance
loncastuximab tesirine (Zynlonta), an antibody-drug conjugate given by IV infusion
What this could lead to
If successful, this study could help determine safe and effective dosing of loncastuximab tesirine for lymphoma patients with liver problems, expanding treatment options for this group.
What could go wrong
This is a very early, small Phase 1b study with only 5 participants, so results may not apply broadly. Liver impairment can increase drug toxicity risks.
