Abstract

Abstract Background The selective BCL2 inhibitor venetoclax (Ven) achieves an overall response rate of approximately 75-80% as a single agent in relapsed and refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (RR-CLL/SLL)1. At one year ~75% of patients (pts) are progression-free at the approved monotherapy dose of 400 mg/day1,2 and Ven is the only novel agent with a significant rate of minimal residual disease (MRD) negativity (MRD-neg)3. The temporal pattern of MRD levels and systematic long term follow up of pts stratified by their MRD status on Ven have not been reported. We report the long term outcomes according to MRD status for 59 pts with RR-CLL/SLL who..
