Diffuse Large B-Cell Lymphoma

Brief summary

This open-label, randomized, parallel group study will evaluate the efficacy and safety of obinutuzumab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisolone or prednisone (CHOP) chemotherapy versus rituximab (MabThera/Rituxan) with CHOP in previously untreated participants with cluster of differentiation 20 (CD20)-positive diffuse large B-cell lymphoma (DLBCL). Participants will be randomized to receive either obinutuzumab 1000 milligrams (mg) intravenously (IV) every 21 days or rituximab 375 milligrams per square meter (mg/m\^2) IV every 21 days for 8 cycles, in addition to 6-8 cycles of CHOP chemotherapy IV every 21 days. Participants randomized to the obinutuzumab arm will receive an additional two doses on Days 8 and 15 of Cycle 1. Anticipated time on study treatment is 24 weeks.

Percentage of Participants With Adverse Events (AEs)Baseline up to approximately 6.5 years (up to 31 January 2018)An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Outcome results

Primary

Median Time to Progression-Free Survival (PFS), Investigator-Assessed

Kaplan Meier estimate of the median PFS was defined as the time at which half of the participants have progressed (progressive disease \[PD\]). Progression-free survival was defined as the time from randomization until the first documented day of disease progression or relapse, using a modified version of the Revised Response Criteria for Malignant Lymphoma, or death from any cause, whichever occurred first, on the basis of investigator assessments. Progression was defined as at least 50% increase in nodal lesions or \>/=50% increase in any node \> 1 centimeter (cm) or \>/= 50% increase in other target measurable lesions (e.g., splenic or hepatic nodules) and/or appearance of any new bone marrow involvement and/or appearance of any new lesion \> 1.5 cm or \>/= 50% increase in any previously involved node with a diameter \</= 1 cm such that it is now \>1.5 cm. Tumor measurements were obtained by computed tomography (CT) or magnetic resonance imaging (MRI).

Time frame: Baseline up to approximately 6.5 years (up to 31 January 2018)

Population: The intent-to-treat (ITT) population included all randomized participants, however because of serious Good Clinical Practice non-compliance at a single study site in China, all 4 participants enrolled at the site (2 in each treatment arm) were excluded from the final analysis.

Duration of Response (DOR), Investigator-Assessed

DOR: time from first occurrence of documented CR or PR to disease progression/relapse, or death from any cause for participants with a response of CR or PR. Tumor assessments were performed with CT/MRI. CR: disappearance of all target lesions. PR: \>/=50% decrease target lesions in up to six dominant lesions identified at baseline, no new lesions and no increase in the size of the liver, spleen, or other nodes. Splenic and hepatic nodule regression \>/= 50%. Progression/relapse: at least 50% increase in nodal lesions or \>/=50% increase in any node \> 1 cm or \>/= 50% increase in other target lesions (e.g., splenic or hepatic nodules) and/or any new bone marrow involvement and/or any new lesion \> 1.5 cm or \>/= 50% increase in any previously involved node with a diameter \</= 1 cm such that it is now \>1.5 cm. A participant in the Rituximab+CHOP arm with the longest follow-up, 53 months, had an event. The criterion for median was the minimum time when survival went below 50%.

Time frame: Baseline up to death or disease progression, whichever occurred first, approximately 6.5 years (up to 31 January 2018)

Population: The intent-to-treat (ITT) population included all randomized participants, of which evaluable participants were included in this analysis, however because of serious Good Clinical Practice non-compliance at a single study site in China, all 4 participants enrolled at the site (2 in each treatment arm) were excluded from the final analysis.

Median Time to Disease-Free Survival (DFS), Investigator-Assessed

Kaplan Meier estimate of median DFS was defined as time at which half of participants have disease progression/relapse or death from any cause. Disease-free survival was defined as time from date of the first occurrence of a documented CR to date of disease progression/relapse or death from any cause on basis of investigator assessments with use of Revised Response Criteria for Malignant Lymphoma.

Percentage of Participants With Adverse Events (AEs)

An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Time frame: Baseline up to approximately 6.5 years (up to 31 January 2018)

Population: The safety analysis population included all participants who received at least one dose of study drug.
