What's the purpose of this trial?
The purpose of this study is to compare the efficacy and safety of glofitamab in combination with polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola-R-CHP) vs Pola-R-CHP in participants with previously untreated CD20-positive large B-cell lymphoma (LBCL).
This trial is currently open and accepting patients.

* Prior treatment with systemic immunotherapeutic agents
* Prior use of any monoclonal antibody for the purposes of treating cancer within 3 months of the start of Cycle 1
* Any investigational therapy for the purposes of treating cancer within 28 days prior to the start of Cycle 1
* Prior radiotherapy to the mediastinal/pericardial region
* Prior therapy for LBCL, with the exception of corticosteriods
* Corticosteroid use \> 30 mg/day of prednisone or equivalent, for purposes other than lymphoma symptom control
* History of other malignant or non-malignant diseases that could affect compliance with the protocol or interpretation of results
* Significant or extensive history of cardiovascular disease

* Any active infection within 7 days prior to Cycle 1 Day 1 that would impact participant safety
* Suspected active or latent tuberculosis
* Positive test results for chronic hepatitis B infection, hepatitis C, or the human T-lymphotropic virus type 1 (HTLV-1)
