Outcome Measures

Primary Outcome Measures :

1. Progression-free Survival (PFS) [ Time Frame: Until progressive disease (PD) [assessed Up to 6.6 Years]. ]
   To assess whether minimal residual disease (MRD)-driven finite AV treatment is NI to MRD-driven finite VO treatment with respect to PFS. PFS is defined as the time from the date of randomization until date of objective progressive disease per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 criteria as assessed by the investigator or death from any cause in the absence of progression.

Secondary Outcome Measures :

1. Rate of peripheral blood (PB) undetectable minimal residual disease (uMRD) based on a clonoSEQ^® [ Time Frame: Screening (Days -45 through -1); Arm A (AV): Day 28 of Cycles 8, 14 and 24 and post treatment follow up visits; Arm B (VO): Day 28 of Cycles 6, 12 and 24 and post treatment follow up visits ]
   To assess the effect of AV treatment compared with VO treatment on uMRD at sequential time points. Rate of PB uMRD is defined as proportion of participants achieving remission based on a clonoSEQ^® assay result of < 1 CLL cell per 100,000 leukocytes (< 10 ^-5 ), after completion of 6 and 12 cycles of venetoclax (assessed at approximately 7/13 and 9/15 months for VO and AV, respectively), and at 24, 36, 48 and 60 months.
2. Rate of peripheral blood (PB) and Bone marrow (BM) undetectable minimal residual disease (uMRD) by flow cytometry [ Time Frame: Cycle 14 (each Cycle length 28 days) Day 28 for Arm A (AV); Cycle 12 Day 28 for Arm B (VO) and Post treatment follow-up visits (assessed Up to 6.6 Years) ]
   To assess the effect of AV treatment compared with VO treatment on uMRD at sequential timepoints. Rate of PB and BM uMRD is defined as < 1 CLL cell per 10,000 leukocytes (< 10^-4) by flow cytometry, after completion of 12 cycles of venetoclax (assessed at approximately 13 and 15 months for VO and AV, respectively) and at 36 months.
3. Overall Survival (OS) [ Time Frame: Date of randomization until death from any cause (Assessed Up to 6.6 Years) ]
   To assess the effect of AV treatment compared with VO treatment on OS. OS is defined as the time from the date of randomization until death from any cause.
4. Event-free Survival (EFS) [ Time Frame: Date of randomization until first occurrence of disease progression (Assessed Up to 6.6 Years) ]
   To assess the effect of AV treatment compared with VO treatment on EFS. EFS is defined as the time from the date of randomization to the first occurrence of disease progression, initiation of subsequent CLL therapy, or death from any cause.
5. Overall Response Rate (ORR) [ Time Frame: Date of randomization until PD (Assessed Up to 6.6 Years) ]
   To assess the effect of AV treatment compared with VO treatment on ORR. ORR is defined as the proportion of participants who achieve best response of Complete Response (CR), complete response with incomplete marrow recovery (Cri), nodular partial remission (nPR), or partial remission (PR) per iwCLL 2018 criteria as assessed by the investigator.
6. Complete Response (CR) rate [ Time Frame: Date of randomization until PD (Assessed Up to 6.6 Years) ]
   To assess the effect of AV treatment compared with VO treatment on ORR. CR rate (uMRD per iwCLL guidelines 2018) after completion of 12 cycles of venetoclax.
7. Change from baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 scales [ Time Frame: For AV: Cycle 1-Cycle 2, Cycle 3-Cycle 14; After End of Treatment (EoT); Post treatment follow-up For VO: Cycle 1 Day 1-21, Cycle 1 Day 22-Cycle 6, Cycle 7-Cycle 24 (Each cycle is 28 days); After EoT, Post treatment follow-up (assessed Up to 6.6 years) ]

   To assess symptoms, functional status and global health status/quality of life (QoL), in participants treated with AV versus VO using the EORTC QLQ-C30.

   EORTC QLQ-C30 consists of 30 items and measures symptoms, functioning, and global health status/QoL for all cancer types. Questions are grouped into 5 multi-item functional scales, 3 multi-item symptom scales, a 2-item global QoL scale, 5 single items assessing additional symptoms commonly reported by cancer participants, and 1 item on the financial impact of the disease.

   The EORTC QLQ-C30 will be scored according to the EORTC QLQ-C30 Scoring Manual. An outcome variable consisting of a score from 0 to 100 will be derived for each of the symptom scales, each of the functional scales, and the global measure of health status scale. Higher scores on the global measure of health status and functional scales indicate better health status/function, but higher scores on symptom scales represent greater symptom severity.

8. Change from baseline in EORTC QLQ-CLL17 scales [ Time Frame: For AV: Cycle 1-Cycle 2, Cycle 3-Cycle 14; After End of Treatment (EoT); Post treatment follow-up For VO: Cycle 1 Day 1-21, Cycle 1 Day 22-Cycle 6, Cycle 7-Cycle 24 (Each cycle is 28 days); After EoT, Post treatment follow-up (assessed Up to 6.6 years) ]

   To assess symptoms, functional status, and global health status/QoL, participants treated with AV versus VO using the EORTC QLQ-CLL17.

   EORTC QLQ-CLL17 comprises 17 items grouped into 3 multi-item scales: 1) symptom burden, 2) physical condition/fatigue, and 3) worries/fears about health and functioning.

   The EORTC QLQ-CLL17 will be scored according to the EORTC QLQ-C30 Scoring Manual. An outcome variable consisting of a score from 0 to 100 will be derived for each of the symptom scales, each of the functional scales, and the global measure of health status scale. Higher scores on the global measure of health status and functional scales indicate better health status/function, but higher scores on symptom scales represent greater symptom severity.

9. Proportion of participants experiencing bruising as measured by the National Cancer Institute (NCI) Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) item for Bruising [ Time Frame: For AV: Cycle 1-Cycle 2, Cycle 3-Cycle 14; After End of Treatment (EoT); Post treatment follow-up For VO: Cycle 1 Day 1-21, Cycle 1 Day 22-Cycle 6, Cycle 7-Cycle 24 (Each cycle is 28 days); After EoT, Post treatment follow-up (assessed Up to 6.6 years) ]

   To assess symptomatic toxicities patient perceived benefit-risk in participants treated with AV versus VO using the NCI PRO-CTCAE item for Bruising.

   It was designed to be used as a companion to the Common Terminology Criteria for Adverse Events (CTCAE), the standard lexicon for adverse event reporting in cancer trials. The bruising item, which has a dichotomous yes/no response option, will be included in this study to capture patient-reported bruising.

10. Proportion of participants reporting each response option of the Patient Global Impression of Benefit-Risk (PGI-BR) [ Time Frame: For AV: Cycle 1-Cycle 2, Cycle 3-Cycle 14 (Each cycle is 28 days); and End of treatment, E/D, disease progression, and post-treatment follow-up visits (assessed up to 6.6 years) ]

    To assess patient perceived benefit-risk of treatment in participants treated with AV versus VO using the PGI-BR.

    PGI-BR consists of 4 study medication-related questions, one each on efficacy, side effects, convenience of use, and overall benefit-risk. Each item is scored separately, with the final item providing a single metric of a participant's overall benefit-risk assessment.

    The response from each question will be semi-quantitative. Each question ranges from Very (negative, Somewhat [negative]), Neutral, Somewhat [positive], Very [positive].

11. Number of participants with adverse events (AEs) [ Time Frame: From screening (Days -45 through -1) until survival follow-up (Up to 6.6 years) ]
    To assess the safety and tolerability of AV treatment versus VO treatment in participants with previously untreated CLL/SLL.
