Summary
This early-stage trial tests an experimental oral drug called ABBV-525 in people with B-cell blood cancers like lymphoma and leukemia. The study aims to find a safe dose and check for side effects. About 78 adults will take the drug in different dose groups over up to 64 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ABBV-525 (MALT1 inhibitor)
- What this could lead to
- If this drug works, it could offer a new treatment option for people with certain blood cancers that haven't responded to other therapies.
- What could go wrong
- This is a very early (Phase 1) trial with only 78 participants, so it's mainly checking safety and dosing. The drug may not work well or could have side effects.
