Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - obinutuzumab
Treatment: Drugs - rituximab
Treatment: Drugs - chlorambucil

Experimental: obinutuzumab + chlorambucil (GClb) - Participants received 1000 mg obinutuzumab intravenous (IV) infusion, on Days 1 \[first infusion split 100 mg on Day 1 and 900 mg on Day 2 as per protocol amendment\], 8 and 15 in Cycle 1 and Day 1 in Cycles 2-6 (28-day cycles) plus chlorambucil 0.5 mg/kg orally on Day 1 and 15 of each 28-day cycle (6 Cycles).

Active comparator: rituximab + chlorambucil (RClb) - Participants received 375 mg/m\^2 rituximab IV infusion on Day 1 of Cycle 1 then 500 mg/m\^2 IV infusions on Day 1 of Cycles 2-6 (28-day cycles) plus chlorambucil 0.5 mg/kg orally on Day 1 and 15 of each 28-day cycle (6 cycles).

Active comparator: Chlorambucil (Clb) - Participants received chlorambucil 0.5 mg/kg orally on Day 1 and 15 of each 28-day cycle (6 Cycles). Participants with Progressive Disease or within 6 months of follow-up were allowed to cross over to receive obinutuzumab + chlorambucil.

Summary
Brief summary
This open-label, randomized, 3-arm study will evaluate the efficacy and safety of (obinutuzumab) RO5072759 in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000 mg intravenous (iv) infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m\^2 cycle 1, 500 mg/m\^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is \>6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.
