In Alliance A041202, a higher than expected number of unexplained deaths were reported with front-line ibrutinib in a patient population aged at least 65 years compared to ECOG 1912, which included patients up to 70 years of age.Methods: Therefore, we conducted a retrospective analysis to investigate whether ibrutinib was associated with a greater mortality in older patients outside of a clinical trial setting. This multicenter analysis was performed by investigators at 20 academic and community practices.Results: Amongst the 391 patients included, there was no correlation between age and response rate, PFS, or OS. However, there was a trend to higher rate of deaths in patients > 65-years-old (8.7% vs 3.8%, p=0.097), with an increased number of early deaths (13 vs 4, p=0.3).Conclusion: These data suggest greater intolerance, and possibly mortality, with ibrutinib in an older population. Patients should be educated regarding the potential complications related to ibrutinib and symptoms of concern to report.Keywords: CLL, ibrutinib, elderly
