There is actually a lot of research that has been done looking at cardiotoxicity with BTK inhibitors especially with ibrutinib, the first generation BTK inhibitor. One of the side effects that has been far less reported are pericardial side effects, things like pericarditis, even up to tamponade. So for this study we looked at pericardial events on the AL41202 study of ibrutinib or ibrutinib plus rituximab in older adults, as well as the E1912 study of ibrutinib plus rituximab in younger adults, all as frontline treatment...

And we did see a small, but I think significant increase in pericardial events in those patients treated with ibrutinib regimens when compared to the chemoimmunotherapy control arms, suggesting that this is in fact a real side effect that we need to be monitoring for. That being said, it is very uncommon. So while it’s something that we should be asking questions about and being clinically aware of, it’s probably not something that we need to be using as a reason to determine a therapy.
