Conditions

Chronic lymphocytic leukemia recurrent

Brief summary

The primary efficacy endpoint is the overall response of CR, CRi, nPR, or PR in Cohort 1 subjects as assessed by the investigator at the EOCT, evaluated 3 months after the EOCT with VenG (EOCT + 3, i.e., Cycle 9)., Disease assessments will be based on the 2018 International Workshop for Chronic Lymphocytic Leukemia criteria for tumor response., Overall response rate is defined as the proportion of subjects achieving a best response of CR, CRi, nPR, or PR.

Detailed description

Overall response of CR or CRi at end of treatment assessment (EOT, assessed at EOT + 3), Overall response of CR, CRi, nPR, or PR at EOT (assessed at EOT + 3), Time to response (TTR), Duration of response (DOR), Time to next treatment (TTNT) for CLL, Progression-free survival (PFS), Overall survival (OS), uMRD rate (< 10-4) at EOCT, measured in PB (assessed at EOCT+ 3), uMRD rate (< 10-4) at EOT, measured in PB (assessed at EOT + 3)
