ASH 2017: Highlights on Chronic Lymphocytic Leukaemia

Speaker: Christian Buske

Reporting from ASH 2017 on Chronic Lymphocytic Leukaemia, Christian Buske discusses studies investigating chemo-free approaches aiming to achieve MRD negativity and/or stopping treatment.  Increased MRD negativity was shown in MURANO with venetoclax+rituximab vs bendamustine+rituximab and in CLARITY with ibrutinib+venetoclax.

The phase III MURANO trial randomised patients with relapsed/refractory CLL to either venetoclax+rituximab vs bendamustine+rituximab. In the VR arm there was >80% risk reduction for PFS and >50% risk reduction for death: this represents a new treatment option for these patients. The CLARITY trial included ~50 patients with relapsed/refractory CLL and >30% MRD negativity was reported at 8 months. These data are encouraging and, in the future, could lead to stopping treatment once MRD negativity is achieved.
