Two-Drug combo targets leukemia that outsmarted its first treatment
NCT ID NCT06191263
First seen Sep 15, 2026 · Last updated Sep 18, 2026 · Updated 2 times
Summary
Researchers are testing whether adding an experimental drug called RVU120 to venetoclax can help adults with acute myeloid leukemia (AML) that has come back or stopped responding to earlier venetoclax-based treatment. The trial enrolls about 98 adults who have already failed a hypomethylating agent plus venetoclax and have few other options. It runs in three parts: first to find safe doses of the two drugs together, then to check safety and response rates, and finally to confirm those results in a larger group. The main goal is to see how many participants achieve complete remission or complete remission with incomplete blood count recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- RVU120, an experimental drug that blocks the CDK8 and CDK19 proteins, given with venetoclax
- What this could lead to
- If the combination works, it could offer a new option for people with AML whose cancer has stopped responding to venetoclax-based therapy, a group with few remaining choices.
- What could go wrong
- This is a mid-stage trial in a hard-to-treat population, and combining two drugs can add side effects. The combination may not shrink the leukemia, and results in this small group may not apply to everyone.
