Phase 2 Study of Disease Risk Mutation-Guided Finite Acalabrutinib+Venetoclax for Relapsed CLL Post-1L Finite cBTKi+BCL2i ± Obinutuzumab
brief summary
This study will evaluate the efficacy and safety of finite-duration acalabrutinib plus venetoclax therapy in patients with relapsed CLL or SLL, and have previously responded to first line (1L) cBTKi + BCL2i therapy (± obinutuzumab) and maintained a response for at least two years post-treatment.
detailed description
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.
