Brief Summary
The primary objective for the phase I part of the study is to investigate the safety and tolerability of escalating intravenous (IV) doses of obinutuzumab given as monotherapy in participants with CD20+ (tumor-infiltrating lymphocytic) Malignant Disease, including B-cell chronic lymphocytic leukemia (CLL) and Non-Hodgkin's Lymphoma (NHL). The primary objective for the phase II part of the study is to investigate the efficacy and safety of one dose of obinutuzumab in participants with relapsed/refractory CLL and NHL that is, in turn, either indolent (iNHL) or aggressive (aNHL). It is an open label dose escalating study in phase I and open label in phase II, but the two doses in iNHL \& aNHL are randomized (to high or low dose of the same open label treatment). CLL was not randomized as only one dose level was used. Participants with a response who might gain additional benefit from being treated again in the opinion of the investigator may be enrolled in a Retreatment Period.

Outcome Measures
Primary Outcomes (2)
Percentage of Participants Who Experienced a Dose-limiting Toxicity in Phase I of the Study
Dose-limiting toxicities were defined as obinutuzumab-related adverse events occurring within the first 28 days of each administration of obinutuzumab, with the exception of B-cell depletion and lymphopenia which are expected outcomes of treatment with obinutuzumab.
Baseline to 28 days after the last infusion of obinutuzumab (up to 6 months)
Percentage of Participants With Best Overall Response in Phase II of the Study
Best overall response (BOR) was defined as the percentage of participants with a complete response (CR) or partial response (PR)
by Cutoff Date: 31 March 2012 (within 3 years, 4 months)
Secondary Outcomes (9)
Percentage of Participants With Complete Response (CR/CRu/CRi) in Phase II of the Study
by Cutoff Date: 31 March 2012 (within 3 years, 4 months)
Percentage of Participants With Partial Response (PR) in Phase II of the Study
by Cutoff Date: 31 March 2012 (within 3 years, 4 months)

by the end of the follow-up period in Phase II of the study (within 3 years, 4 months)

1000/1000 mg - Phase II, CLL
EXPERIMENTALParticipants in this CLL arm received an intravenous infusion of obinutuzumab 1000 mg on Days 1, 8, and 15 of Cycle 1 and obinutuzumab 1000 mg on Day 1 of Cycles 2-8 for a maximum of 8 cycles and 10 infusions. Each cycle was 21 days.
Retreated Participants
EXPERIMENTALParticipants who might benefit from retreatment who were allowed to be treated again via intravenous infusion of obinutuzumab at the request of the investigator.
Interventions
Obinutuzumab was provided in single-dose glass vials as a freeze-dried powder.

Limitations and Caveats
Pharmacodynamic results were limited because number of participants was inversely proportional to length of follow-up. In other words, there were fewer participants still in the trial as the follow-up period became longer.
