Brief Summary
The purpose of this study is to assess progression-free survival (PFS) from treatment with ibrutinib plus venetoclax (I+VEN) compared with obinutuzumab plus chlorambucil (G-Clb) as assessed by an Independent Review Committee (IRC).

Outcome Measures
Primary Outcomes (1)
Progression Free Survival (PFS)
PFS: time between date of randomization and date of disease progression, as assessed by IRC, or date of death due to any cause, whichever occurs first, regardless of use of subsequent anti-cancer therapy prior to PD or death using iWCLL2008 criteria : New enlarged lymph nodes \>15 mm, new hepatomegaly or splenomegaly, or other organ infiltrates, bone lesion, ascites or pleural effusion due to CLL; \>=50% increase in longest diameter (LDi) from nadir in existing lymph node (LDi \>15 mm) or \>=50% increase from nadir in sum of diameters of multiple nodes (and at least 1 node with LDi \>15 mm); \>=50% increase from nadir in enlargement of liver/spleen; \>=50% increase from baseline in lymphocyte count (ALC; to \>=5\*10\^9/L); or \>=50% increase from nadir in ALC in \>=2 serial assessments if ALC is \>=30000\*10\^9/L and lymphocyte doubling time is rapid unless considered treatment-related lymphocytosis; new cytopenia attributable to CLL; transformation to more aggressive histology.

Study Arms (2)
Treatment Arm A: Ibrutinib and Venetoclax (I+VEN)
EXPERIMENTALParticipants will initially receive ibrutinib (420 mg \[milligrams\]/day) for 3 cycles. Venetoclax dose ramp up (from 20 to 400 mg over 5 weeks) will begin at Cycle 4 and the combination of ibrutinib and venetoclax will be given for 12 cycles (each cycle is equivalent to 28 days). Participants who subsequently develop progressive disease may enter to Subsequent Therapy Phase to receive single-agent ibrutinib until disease progression or unacceptable toxicity.
Treatment Arm B: Chlorambucil and Obinutuzumab (G-Clb)
ACTIVE COMPARATORParticipants will receive chlorambucil and obinutuzumab (G-Clb) for 6 cycles. Participants will receive obinutuzumab, 1000 mg intravenously (IV) on Days 1, 8 and 15 of Cycle 1, and on Day 1 of Cycles 2 to 6 and chlorambucil 0.5 milligrams per kilogram (mg/kg) body weight, on Days 1 and 15 of Cycles 1 to 6. Participants who subsequently develop progressive disease may enter to Subsequent Therapy Phase to receive single-agent ibrutinib until disease progression or unacceptable toxicity.
Interventions
Participants will receive ibrutinib 420 mg orally once daily up to 15 cycles.
Participants will receive venetoclax in combination with ibrutinib for a total of 12 cycles, beginning at Cycle 4. For the first 5 weeks of venetoclax treatment, the treatment dose will be ramped up from 20 to 400 mg.
Participants will receive chlorambucil at a dose of 0.5 mg/kg body weight on Days 1 and 15 of Cycles 1 to 6.
Participant will receive obinutuzumab 1000 mg intravenously on Days 1, 8, and 15 of Cycle 1, and Day 1 of Cycles 2 to 6.
Participants will receive ibrutinib 420 mg orally once daily until disease progression or unacceptable toxicity during the subsequent therapy phase.
Eligibility Criteria
You may qualify if:
- Adult participants who are: (a) greater than or equal to (\>=) 65 years old or, (b) 18 to 64 years old and have at least 1 of the following:

- Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) Grade less than or equal to (\<=) 2
- Active CLL/SLL requiring treatment per the iwCLL criteria
You may not qualify if:
- Prior anti-leukemic therapy for CLL or SLL
- Presence of deletion of the short arm of chromosome 17 (del17p) or known TP53 mutation detected at a threshold of \>10 percent (%) variable allele frequency (VAF)
- Major surgery within 4 weeks of first dose of study treatment
- Known bleeding disorders (example, von Willebrand's disease or hemophilia)
- Central nervous system (CNS) involvement or suspected Richter's syndrome
