Purpose
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).
Detailed Description
The hypothesis is treatment with combination of I+VEN will result in longer PFS compared with
G-Clb in participants with previously untreated chronic lymphocytic leukemia (CLL)/ small
lymphocytic lymphoma (SLL) who meet International Workshop on CLL (iwCLL) treatment criteria.
The study includes screening (30 days), treatment (from randomization until treatment
discontinuation) and follow-up phase (from treatment discontinuation until Subsequent Therapy
Phase [if applicable], death, lost to follow up, consent withdrawal, or study end, whichever
occurs first). Participants without progression will continue disease evaluations until
disease progression or death. Participants from either treatment arm that develop progressive
disease may be eligible to receive single-agent ibrutinib until disease progression or
unacceptable toxicity (Subsequent Therapy Phase). Participation in this phase of the study is
not mandatory and is based on investigator's discretion. Study duration is approximately 6
years. Safety includes review of adverse events and laboratory tests performed over time.
Trial Arms
Name | Type | Description | Interventions |

Treatment Arm A: Ibrutinib and Venetoclax (I+VEN) | Experimental | Participants 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. | - Ibrutinib
- Venetoclax
- Ibrutinib (as Subsequent Therapy)

Treatment Arm B: Chlorambucil and Obinutuzumab (G-Clb) | Active Comparator | Participants 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. | - Chlorambucil
