New hope for tough lymphomas? early trial of NB02 begins
NCT ID NCT07114367
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial is testing a new drug called NB02 (posseltinib) in 9 adults with certain types of Non-Hodgkin lymphoma (follicular, mantle cell, or marginal zone) that have returned or not responded to at least two prior treatments. The main goals are to find a safe dose and check for side effects, while also looking for signs that the drug might fight the cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NB02 (posseltinib)
- What this could lead to
- If this works, it could point toward a new treatment option for people with certain types of Non-Hodgkin lymphoma that have not responded to other therapies.
- What could go wrong
- This is a very early, small Phase 1 trial with only 9 participants, so it is mainly checking safety and dosing. It is too soon to know if the drug will effectively shrink tumors or help patients feel better.
