  • A participant using oral contraceptives must use an additional contraceptive method
  • A participant must agree not to be pregnant, breastfeeding, or planning to become pregnant while enrolled in this study or until 1 month after last dose or per local label if more conservative (for example, 3 months in European Union or Canada and 1 month in United States)

Exclusion criteria

  • Uncontrolled autoimmune hemolytic anemia or idiopathic thrombocytopenia purpura, such as those participants with a declining hemoglobin level or platelet count secondary to autoimmune destruction within the 4 weeks prior to first dose of study treatment, or the need for prednisone greater than (>) 20 milligrams (mg) daily (or corticosteroid equivalent) to treat or control the autoimmune disease

320 participants in 4 patient groups

Cohort 1a: Ibrutinib Lead-in+Fixed Duration Ibrutinib+Venetoclax
Experimental group
Description:
Participants will receive ibrutinib 420 milligrams (mg) capsule every day (QD) for a lead-in of 3 cycles (1 cycle = 28 days). From Cycle 4, venetoclax 400 mg tablet dose ramp-up (from 20 to 400 mg over 5 weeks) will begin, and venetoclax 400 mg QD will be administered with ibrutinib 420 mg QD, orally for 12 cycles through Cycle 15.
Treatment:
Drug: Ibrutinib
Drug: Venetoclax
Cohort 1b: Ibrutinib Lead-in+Fixed Duration Ibrutinib+Venetoclax
Experimental group
Description:
Participants will receive ibrutinib 420 mg capsule QD for a lead-in of 3 cycles (1 cycle = 28 days). From Cycle 4, venetoclax 400 mg tablet dose ramp-up (from 20 to 400 mg over 5 weeks) will begin and ibrutinib dose will be reduced to 280 mg and will be administered QD, venetoclax 400 mg tablets QD will be administered with ibrutinib 280 mg for 12 cycles through Cycle 15.
Treatment:
Drug: Ibrutinib
Drug: Venetoclax
Cohort 2a: Continuous Ibrutinib Monotherapy
Experimental group
Description:
Participants will receive ibrutinib 420 mg QD (or last tolerated dose) until disease progression (PD) or unacceptable toxicity.
Treatment:
Drug: Ibrutinib
Cohort 2b: Continuous Ibrutinib Monotherapy
Experimental group
Description:
Participants will receive ibrutinib 420 mg QD for 1 cycle (1 cycle = 28 days) followed by Ibrutinib 280 mg QD (or last tolerated dose) and continue until disease progression or unacceptable toxicity.
Treatment:
Drug: Ibrutinib
