Brief summary

Progression-free survival (PFS)

Detailed description

Rates of undetectable MRD (uMRD, i.e. <10E-4) in peripheral blood (PB) and bone marrow (BM) at final restaging (RE), which will be at cycle 18 after start of treatment, and additional BM assessment approx. 12 months after RE, MRD levels in PB at different time points (cycle 1 before start of ther-apy, start of cycle 7, start of cycle 13 [end of VG treatment], start of cycle 16 [end of VI treatment], final restaging [cycle 18], afterwards every 6 months to end of study), Duration of undetectable MRD (uMRD), Overall response rate (ORR; defined as rate of a response of CR, CRi, or PR) as per iwCLL guidelines at final restaging, Duration of response, Complete response rate (CRR; defined as rate of a response of CR or CRi) at final restaging as per iwCLL guidelines, Overall survival (OS), Event-free survival (EFS) (I vs VG and I vs VI), Time to next treatment (TTNT), PFS2 (i.e. PFS after second-line treatment)
