Groups in this outcome

IBR+OB

Ibrutinib (IBR) given orally at a dose of 420 mg/day until progressive disease or unacceptable toxicity. Intravenous obinutuzumab (OB) given on Days 1 and 2 (100 mg on Day 1 and 900 mg on Day 2), 1000 mg on Days 8 and 15 of Cycle 1 and 1000 mg on Day 1 of each cycle up to 6 cycles or until progressive disease or unacceptable toxicity.

CLB+OB

Chlorambucil (CLB) given orally at a dose of 0.5 mg/kg body weight up to a total of 6 cycles on Days 1 and 15 of each cycle or until disease progression or unacceptable toxicity. Intravenous obinutuzumab (OB) given on Days 1 and 2 (100 mg on Day 1 and 900 mg on Day 2), 1000 mg on Days 8 and 15 of Cycle 1 and 1000 mg on Day 1 of each cycle up to 6 cycles or until disease progression or unacceptable toxicity.
