Early results from an ongoing study show that ibrutinib (Imbruvica) keeps relapsed chronic lymphocytic leukemia (CLL) from worsening for longer than ofatumumab (Arzerra), a standard treatment option for relapsed or refractory CLL. CLL is the most common type of leukemia in adults. Relapsed CLL is when the disease returns after remission, a time when there are no signs or symptoms of the disease. Refractory CLL is when the disease worsens despite treatment.
