According to preliminary results of a phase II trial, the combination of obinutuzumab (Gazyva), ibrutinib (Imbruvica), and venetoclax (Venclexta) is a safe initial therapy for treatment-na&iuml;ve patients with chronic lymphocytic leukemia (CLL).

According to Neil E. Kay, MD, novel agents,&nbsp;such as&nbsp;ibrutinib (Imbruvica), venetoclax (Venclexta), idelalisib (Zydelig), and acalabrutinib (Calquence), are revolutionizing treatment for patients with chronic&nbsp;lymphocytic leukemia. However, the best way to sequence these agents to maximize the benefit to patients is still unclear.
