Participants will receive placebo and standard premedications on Days 1 and 2 of Cycle 1 (cycle length= 28 days) along with obinutuzumab and chlorambucil administered for 6 cycles.

Participants will receive tocilizumab and standard premedications on Days 1 and 2 of Cycle 1 (cycle length= 28 days) along with obinutuzumab and chlorambucil administered for 6 cycles.

Chlorambucil at a dose of 0.5 milligrams per kilogram (mg/kg) will be administered orally per local prescribing information, on Days 1 and 15 of Cycles 1 to 6.

Obinutuzumab at a dose of 100 milligrams (mg) as an intravenous (IV) infusion will be administered on Cycle 1 Day 1; 900 mg as IV infusion on Cycle 1 Day 2; 1000 mg as IV infusion on Cycle 1 Days 8 and 15; and 1000 mg as IV infusion on Day 1 of each subsequent cycle for up to 6 cycles.

Placebo matching to tocilizumab will be administered as IV infusion on Cycle 1 Day 1 (prior to the first dose of obinutuzumab).

Placebo

Standard-of-care premedication consisting of antipyretic, antihistamine, and corticosteroid will be administered as per United States Package Insert/ Summary of Product Characteristics on Cycle 1 Days 1 and 2 (prior to the first and second dose of obinutuzumab, respectively).

Standard Premedication

Tocilizumab at a dose of 8 mg/kg or adjusted dose (up to a maximum threshold of 20 mg/kg) will be administered as IV infusion on Cycle 1 Day 1 (prior to the first dose of obinutuzumab).

Tocilizumab

Clinical Trials

This multicenter, double-blind, randomized, placebo-controlled study will evaluate the safety of a single infusion of tocilizumab versus placebo, administered in addition to standard premedications (antipyretic, antihistamine, and corticosteroid) prior to the first infusion of obinutuzumab administered in combination with oral chlorambucil to participants with previously untreated B-CLL who have comorbidities. All eligible participants will be treated with a total of 6 cycles of obinutuzumab + chlorambucil (cycle length = 28 days).
