Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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) [ Time Frame: Baseline to best overall response at or before the initiation of subsequent anti-cancer therapy (if any) (approximately 3 years and 5 months) ]
    ORR as assessed by independent review committee (IRC) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 criteria


Secondary Outcome Measures :
  1. Event-Free Survival (EFS) [ Time Frame: 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) ]
    EFS by IRC per iwCLL 2018 criteria

  2. Progression-Free Survival (PFS) [ Time Frame: Randomization to PD (per iwCLL 2018 criteria) or death from any cause (approximately 5 years 8 months) ]
    PFS by IRC per iwCLL 2018 criteria

  3. Duration of Response (DOR) [ Time Frame: 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) ]
    DOR

  4. Overall Survival (OS) [ Time Frame: Randomization to death from any cause (approximately 6 years) ]
    OS

  5. Time to Next Treatment (TTNT) [ Time Frame: Randomization to initiation of the next systemic anticancer therapy for CLL/SLL or death from any cause, whichever occurs first (approximately 6 years) ]
    TTNT

  6. Time to Worsening (TTW) of CLL/SLL Related Symptoms [ Time Frame: Randomization to time to worsening symptoms (approximately 6 years) ]
    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.
