Plain Language Summary of the iNNOVATE study: ibrutinib plus rituximab is well-tolerated and effective in people with Waldenström's macroglobulinemia.

This article provides a short summary of 5-year results from the iNNOVATE trial. The original paper was published in the During the 5 years of monitoring, more people who took ibrutinib plus rituximab experienced an improvement in their disease and lived longer without their disease getting worse compared to those who took placebo plus rituximab. Side effects from ibrutinib and rituximab were manageable and generally decreased over time. Participants in both study groups reported improvements in quality of life, but those who took ibrutinib plus rituximab reported significantly greater improvement in their quality of life (as measured by FACT-An score) compared to those who took placebo plus rituximab. These results show that ibrutinib plus rituximab is better than rituximab alone in people with WM and that ibrutinib plus rituximab is safe and effective in the long term. This information confirms the role of ibrutinib plus rituximab as a standard of care for WM.
