New combo aims to tackle returning blood cancer
NCT ID NCT07024706
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 3 times
Summary
This phase 2 trial tests a combination of two drugs, acalabrutinib and venetoclax, in 80 people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) whose cancer has returned after initial treatment. Participants must have responded well to their first therapy and stayed in remission for at least two years. The study aims to see if this finite-duration combo can effectively control the disease again.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- acalabrutinib and venetoclax
- What this could lead to
- If successful, this could offer a new treatment option for people with CLL/SLL whose cancer returns after initial therapy, potentially extending remission without continuous medication.
- What could go wrong
- This is a small, early-phase study (80 people) with no results yet. The treatment may not work as well as hoped, and side effects like low blood counts or infections are possible.
