Liver-Friendly lymphoma treatment? new drug dosing study offers hope

NCT ID NCT05660395

First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time

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.
