  3. Number of Participants With Adverse Events (AEs) (Safety Run-in Period) [ Time Frame: Up to approximately 5 years ]
    An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.

  4. Overall response rate (ORR) (Safety Run-in Period) [ Time Frame: approximately 1 year after last subject has stopped treatment with study drug(s) ]
    ORR is defined as CR or PR per investigator assessment according to the Revised Response Criteria for Malignant Lymphoma.

  5. Duration of Response (DOR) (Safety Run-in Period) [ Time Frame: Up to approximately 5 years ]

    To evaluate PFS of ibrutinib and venetoclax compared to ibrutinib and placebo.

  9. Complete Response (CR) (Treatment-Naive Arm) [ Time Frame: approximately 1 year after last subject has stopped treatment with study drug(s) ]
    To evaluate the complete response (CR) rate with the combination of ibrutinib and venetoclax in subjects with treatment-naive MCL


Secondary Outcome Measures :
  1. Complete Response (CR) (Randomization Period) [ Time Frame: approximately 1 year after last subject has stopped treatment with study drug(s) ]
    Complete response rate (CR) based on the best overall response per investigator assessment according to the Revised Response Criteria for Malignant Lymphoma.

  2. Overall response rate (ORR) (Randomization Period and Treatment-Naive Arm) [ Time Frame: approximately 1 year after last subject has stopped treatment with study drug(s) ]

  3. MRD-negative remission rate in participants who achieve CR per investigator assessment (Randomization Period and Treatment-Naive Arm) [ Time Frame: approximately 1 year after last subject has stopped treatment with study drug(s) ]
    MRD-negative remission is defined as undetectable MRD at documented CR in subjects who were MRD positive at screening as assessed by flow cytometry in bone marrow and/or peripheral blood, with requirement of confirmation of MRD negativity in the subsequent peripheral blood 12 weeks later.

  4. Overall Survival (OS) (Randomization Period and Treatment-Naive Arm) [ Time Frame: Up to approximately 5 years ]
    OS is defined as the time from the date of the first dose of study treatment to death from any cause.

  5. Duration of Response (DOR) (Randomization Period and Treatment-Naive Arm) [ Time Frame: Up to approximately 5 years ]
    DOR is defined as participants who achieve an overall response as the time from the first occurrence of response (CR or PR) to disease progression or death, whichever occurs first.

  6. Time to Next Treatment (TTNT) (Randomization Period and Treatment-Naive Arm) [ Time Frame: Up to approximately 5 years ]
    TTNT is defined as the duration from the date of randomization to the start date of any anti-lymphoma treatment subsequent to study treatment.
