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.
