Ibrutinib and venetoclax as primary therapy in symptomatic, treatment-naïve Waldenström macroglobulinemia
This combination had impressive results but led to a high rate of ventricular arrythmias (9%), hence the combination is not recommended. Another study with the combination and rituximab was also suspended, the etiology of the higher rate of Vent arrhythmias is not known. This combination in another lymphoid malignancies did not lead to that rate of toxicity.
