Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2
-CD20+ aggressive lymphoma as determined by the local hemopathology laboratory from the following diagnoses by 2016 World Health Organization classification of lymphoid neoplasms: DLBCL, not otherwise specified (NOS); high-grade B-cell lymphoma (NOS or double/triple hit); transformed follicular lymphoma; follicular lymphoma Grade 3b
-Have disease relapsed or refractory to at least one prior systemic therapy for aggressive non-Hodgkin's lymphoma (aNHL)
-Participants who have received only one prior line of therapy must be ineligible for autologous stem cell transplant (ASCT)
-Measurable disease
-Adequate hepatic, hematologic, and renal function
-Negative HIV test at screening. Participants with a positive HIV test at screening are eligible provided that, prior to enrollment, they are stable on anti-retroviral therapy for at least 4 weeks, have a CD4 count of at least 200 microliters, have an undetectable viral load, and have not had a history of opportunistic infection attributable to AIDS within the last 12 months
-Pregnant or breast feeding, or intending to become pregnant during the study or within 3 months after the final dose of mosunetuzumab, 9 months after the final dose of polatuzumab vedotin, 12 months after the final dose of rituximab, 6 months after the final dose of gemcitabine, 9 months after the final dose of oxaliplatin, and 3 months after the final dose of tocilizumab, as applicable
-Inability to comply with protocol-mandated activity restrictions
-Prior treatment with mosunetuzumab or other CD-20-directed bispecific antibodies or R-GemOx or Gem-Ox
-Prior treatment with polatuzumab vedotin, with the following exceptions: participants who have a documented response (partial response or complete response) to polatuzumab vedotin and an absence of PD within 12 months from the last dose of polatuzumab vedotin; participants who received up to 2 doses of a polatuzumab vedotin-containing regimen as bridging to CAR-T therapy, and either has a documented disease control (stable disease, partial response, or complete response), or were not assessed for response following treatment with polatuzumab vedotin
-Contraindication to any component of the study treatment
-Grade > 1 peripheral neuropathy
-Received anti-lymphoma treatments with monoclonal antibodies, radio-immunoconjugates or antibody-drug conjugates (ADCs) within 4 weeks before the first dose of study treatment
-Treatment with any chemotherapeutic agent, or treatment with any other anti-cancer agent (investigational or otherwise) within 4 weeks or 5 half-lives of the drug, whichever is shorter, prior to the first dose of study treatment
-Treatment with radiotherapy within 2 weeks prior to the first dose of study treatment
-ASCT within 100 days prior to the first study treatment administration
-Prior treatment with chimeric antigen receptor (CAR) T cell therapy within 30 days before the first study treatment administration

-Known or suspected history of hemophagocytic lymphohistiocytosis (HLH)
-History of confirmed progressive multifocal leukoencephalopathy
-History of severe allergic or anaphylactic reactions to monoclonal antibody therapy
