NCT ID NCT04049825
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This early-phase trial tested an experimental drug called OPB-111077 combined with two standard chemotherapy drugs (bendamustine and rituximab) in 36 people whose diffuse large B-cell lymphoma had come back or stopped responding to treatment. The main goal was to check the safety and find the right dose, not to measure how well it works. The study is already completed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- OPB-111077 (an experimental drug) combined with bendamustine and rituximab (standard chemotherapies)
- What this could lead to
- If successful, this could point toward a new combination treatment option for people with relapsed or refractory diffuse large B-cell lymphoma.
- What could go wrong
- This is a very early (Phase 1) trial with only 36 participants, focused on safety and dosing. It is not designed to prove effectiveness, and the combination may cause significant side effects or fail to work in larger studies.
