Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To determine the uMRD rate in PB and BM by flow cytometry	measured by 8-color flow cytometry with a quantitative lower limit of detection of at least 10-4 (1 in 10,000 cells).	2 year
Secondary	ORR	The ORR will be measured by the proportion of subjects having achieved a CR/CRi (CR with incomplete recovery in BM) or partial response (PR) according to the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) guidelines (2018)	2 years
Secondary	Progression Free Survival	PFS will be measured as the time from first dose date until progression according the iwCLL criteria or death from any cause.	5 years
