| Measure | Time frame |
|---|---|
| Main Objective: - To evaluate the efficacy of 6 cycles ibrutinib/obinutuzumab in converting patients who are not in CR or who have detectable MRD on combination ibrutinib and venetoclax in uMRD (BM) CR ;Secondary Objective: - To explore the kinetics of CLL clearance on protocol and in follow up within the different compartments (PB, BM, LN) by regular test methods (MRD, PET -CT and BM) - To measure the conventional response and outcomes of the combination ibrutinib/venetoclax and intensification with ibrutinib/obinutuzumab - To evaluate prognostic parameters for response on ibrutinib/venetoclax and intensification with ibrutinib/obinutuzumab - To evaluate safety of ibrutinib/venetoclax and intensification with ibrutinib/obinutuzumab Exploratory - To explore kinetics of CLL clearance on protocol and in follow up within different compartments (PB, BM, LN) by novel test methods (MRD, PET -CT, fine needle aspiration (FNA) of LN) - To evaluate the impact on immunity (e.g. expression of CD20 and CXCR4/CD5) of ibrutinib/venetoclax and intensification with ibrutinib/obinutuzumab - To evaluate quality of life (QoL) during and after ibrutinib/venetoclax and intensification with ibrutinib/obinutuzumab ;Primary end point(s): • BM uMRD CR 3 months after end of intensification with ibrutinib/obinutuzumab in patients who were not in CR or who had detectable MRD on combination ibrutinib and venetoclax;Timepoint(s) of evaluation of this end point: When relevant data of all patients are available and validated | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • BM uMRD CR 9 months after registration 2 in all subjects • Best BM MRD level during on protocol • MRD level in BM and PB at different time points on protocol and in follow up • Best response by IWCLL on protocol • Response by IWCLL at different time points • Response by Deauville criteria on PET scan at different time points • Progression free survival (PFS), defined as time from registration 1 and from registration 2 to progression or death from any cause, whichever comes first • Event free survival (EFS), defined as time from registration 1 and from registration 2 to start new CLL treatment, progression or death, whichever comes first • Overall survival (OS), defined as time from registration 1 and from registration 2 to death from any cause • Treatment free interval (TFI), defined as date of last protocol treatment to start date of first CLL treatment off protocol, or death from any cause whichever comes first • Predictive value of prognostic markers at diagnosis on uMRD and ORR by IWCLL and Deauville criteria at end of ibrutinib/venetoclax and ibrutinib/obinutuzumab • CTCAE grade =2 toxicities • IWCLL hematological grade = 2 toxicities Exploratory endpoints • MRD level in BM and PB at different time points on protocol and in follow up by novel techniques • Quantification of lesions on 18F-FDG PET-CT at different time points • Amount of CLL cells in LN biopsy and FNA • Immune cell subsets and function at different time points • QoL at different time points on protocol and in follow up ;Timepoint(s) of evaluation of this end point: When relevant data of all patients are available and validated | — |
