The 5-Year Follow-Up Of A Real-World Observational Study Of Patients In The United Kingdom And Ireland Receiving Ibrutinib For Relapsed/Refractory Mantle Cell Lymphoma

This is a 5-year real-world study of 65 patients treated with ibrutinib for relapsed/refractory mantle cell lymphoma across the UK and Ireland. Ibrutinib was well tolerated with no fatal adverse events. The median progression-free survival and overall survival (OS) was 12 and 18 center dot 5 months, respectively. Overall, 80% of patients discontinued treatment, predominantly for progressive disease. On discontinuation, 20% received alternative immunochemotherapy with a median OS of 24 months. Ibrutinib was used as a bridge to transplant in 8% (median OS not reached). These observations are comparable with trial outcomes with encouraging responses to immunochemotherapy at relapse.
