New pill KQB198 tested for tough blood cancers
NCT ID NCT06645886
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests a new oral drug called KQB198, alone or with another drug (dasatinib), in 13 adults with advanced blood cancers that have not responded to prior treatments. The main goals are to find a safe dose and see if the drug can shrink tumors. Participants take the drug daily and visit the clinic regularly for monitoring.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- KQB198 (oral drug) and dasatinib (oral drug)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced blood cancers that have stopped responding to other therapies.
- What could go wrong
- This is a very early (Phase 1) trial with only 13 participants, so it is mainly checking safety and dosing. It is too small and early to know if the drug will work or be safe for wider use.
