New drug cocktail aims to tackle tough blood cancers
NCT ID NCT07520006
First seen Jun 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This study tests a new drug called NX-5948 (bexobrutideg) combined with other medicines (venetoclax, and possibly rituximab or obinutuzumab) in adults with B-cell lymphoma, chronic lymphocytic leukemia, or small lymphocytic lymphoma. The goal is to see if the combination is safe and effective for people whose cancer has returned or not responded to prior treatments, as well as for those receiving first-time therapy. About 150 participants will take part across multiple centers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NX-5948 (bexobrutideg) combined with venetoclax and possibly rituximab or obinutuzumab
- What this could lead to
- If successful, this could offer a new combination treatment option for people with certain blood cancers that have stopped responding to standard therapy.
- What could go wrong
- This is an early-phase trial (1b/2) with a small number of participants, so results may not apply broadly. Side effects from the drug combinations are possible and not yet fully known.
