Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Achieving Complete Response (CR), Complete Remission with Incomplete Hematologic Recovery (Cri), Nodular Partial Remission (nPR) or Partial Response (PR): Overall Response Rate (ORR)	ORR as assessed by independent review committee (IRC) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 criteria	Baseline to best overall response at or before the initiation of subsequent anti-cancer therapy (if any) (approximately 3 years and 5 months)
Secondary	Event-Free Survival (EFS)	EFS by IRC per iwCLL 2018 criteria	Randomization to first occurrence of treatment discontinuation due to adverse event/toxicity, treatment-emergent atrial fibrillation or atrial flutter of any grade, progressive disease (PD) or death (approximately 4 years)
Secondary	Progression-Free Survival (PFS)	PFS by IRC per iwCLL 2018 criteria	Randomization to PD (per iwCLL 2018 criteria) or death from any cause (approximately 5 years 8 months)
Secondary	Duration of Response (DOR)	DOR	Time from the date of the first documented response of CR, CRi, nPR or PR to the earlier of documentation of definitive PD (per iwCLL 2018 criteria) or death from any cause (approximately 2 years)
Secondary	Overall Survival (OS)	OS	Randomization to death from any cause (approximately 6 years)
Secondary	Time to Next Treatment (TTNT)	TTNT	Randomization to initiation of the next systemic anticancer therapy for CLL/SLL or death from any cause, whichever occurs first (approximately 6 years)
Secondary	Time to Worsening (TTW) of CLL/SLL Related Symptoms	Using symptom questions identified from the EORTC item library. The range of raw scores for these items could be from 0 to 52 with highest score being worse symptoms.	Randomization to time to worsening symptoms (approximately 6 years)
