Abstract

8028 Background: Ven + rituximab (VenR) has a manageable safety profile and improves survival in patients (pts) with R/R CLL, but discontinuation/interruption is frequent. We present new data from the Phase III MURANO study on the impact of Ven early discontinuation/interruption on outcomes in pts with R/R CLL. Methods: Time-dependent Cox proportional hazards regression models, stratified by 17p deletion and risk status, evaluated the impact of Ven discontinuation/interruption on investigator-assessed PFS and OS. Analyses were performed retrospectively (without type-1 error control) in intent-to-treat pts with R/R CLL from the fixed-duration VenR arm of MURANO (NCT02005471; data cut-off: Ma..
