NCT ID NCT04075292

First seen Nov 21, 2025 · Last updated May 14, 2026 · Updated 25 times

Summary

This study tests whether a targeted drug called acalabrutinib works better than a standard combination of chemotherapy (chlorambucil) and an antibody (rituximab) for people with untreated chronic lymphocytic leukemia (CLL). About 155 adults aged 65 or older (or younger with certain health issues) took part. The main goal was to see how long patients lived without their cancer getting worse.
