Phase 2 Study of Disease Risk Mutation-Guided Finite Acalabrutinib+Venetoclax for Relapsed CLL Post-1L Finite cBTKi+BCL2i ± Obinutuzumab

80 patients around the world

Available in United States, Brazil

The purpose of this study is to explore the use of second line (2L) treatment with AV after relapse following first line (1L) cBTKi + BCL2i by assessment of ORR in participants with CLL/SLL. This study will generate efficacy and safety data needed to understand outcomes associated with AV in patients who initially responded with partial remission (PR) or better for a minimum of 2 years from the end of 1L cBTKi + BCL2i combination treatment and are experiencing clinical relapse requiring further treatment. MAVRiC explores AV as second-line (2L) CLL/SLL treatment after relapse on first-line (1L) cBTKi + BCL-2 by assessment of overall response rate (ORR) - The study duration for each participant will be up to 5 year. - The study consists of screening, treatment, and post-intervention follow-up periods. - Participants will be grouped into low or high risk cohorts based on disease risk determined by IGHV mutation and TP53 aberrancy.
