Summary

This Phase 3 trial compares the drug acalabrutinib to a combination of chlorambucil and rituximab in people with previously untreated chronic lymphocytic leukemia (CLL). The study includes 155 participants and measures how long the cancer stays under control (progression-free survival). The goal is to see if acalabrutinib works better or has fewer side effects than the current standard therapy.
