Diffuse Large B-Cell Lymphoma
Conditions
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.
Interventions
Rituximab at a dose of 375 mg/m\^2, administered by intravenous (IV) infusion on Day 1 of each 21-day cycle for 8 cycles.
Obinutuzumab 1000 mg IV infusion, administered on Day 1 of each 21-day cycle for 8 cycles. During Cycle 1, obinutuzumab was also infused on Days 8 and 15.
Cyclophosphamide 750 milligrams per square metre (mg/m\^2), administered intravenously (IV) on Day 1 of each 21-day cycle.
Doxorubicin 50 mg/m\^2 IV, administered on Day 1 of each 21-day cycle.
Vincristine 1.4 mg/m\^2 (maximum 2 mg) IV, administered on Day 1 of each 21-day cycle.
Prednisone 100 mg (or equivalent prednisolone or methylprednisolone), administered orally on Days 1-5 of each 21-day cycle.

Percentage of participants with complete response was determined on the basis of IRC assessments according to the International Working Group (IWG) Revised Response Criteria for Malignant Lymphoma, 2007. Tumor assessments were performed with CT/MRI with or without PET. Complete response was defined as the disappearance of all evidence of disease. This outcome measure used data from primary analysis which included all 1418 participants.
Time frame: Baseline up to approximately 4 years and 9 months (up to 29 April 2016)
Population: The intent-to-treat (ITT) population included all randomized participants.
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Rituximab+Chemotherapy | Complete Response (CR) at the End of Treatment, IRC-Assessed | Without PET | 34.4 percentage of participants |
| Rituximab+Chemotherapy | Complete Response (CR) at the End of Treatment, IRC-Assessed | With PET | 65.3 percentage of participants |

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)

Tumor assessments were performed with CT/MRI. CR was defined as disappearance of all target lesions. Progression/relapse 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.

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.
