New targeted drug shows promise for Hard-to-Treat leukemia
NCT ID NCT02337829
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This study tested a drug called acalabrutinib in 48 adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who had a specific high-risk genetic change (deletion 17p). Some participants had already tried other treatments, while others were newly diagnosed. The goal was to see how well the drug shrank or controlled the cancer by blocking a key protein (BTK) that helps cancer cells grow. Results were measured using standard response criteria.
