Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Gemcitabine + Glofitamab + Oxaliplatin

Participants will receive a single dose of intravenous (IV) obinutuzumab pretreatment 7 days prior to the first dose of glofitamab, followed by up to 8 cycles of glofitamab + gemcitabine + oxaliplatin. This will be followed by up to 4 cycles of glofitamab monotherapy, for a total of up to 12 cycles of glofitamab (cycle length = 21 days).

Group Type EXPERIMENTAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Histologically confirmed DLBCL, not otherwise specified (NOS)

* At least one prior line of systemic therapy
* Participants who have failed only one prior line of therapy must not be a candidate for high-dose chemotherapy followed by autologous stem cell transplant (ASCT)
* At least one bi-dimensionally measurable (\> 1.5 cm) nodal lesion, or one bi-dimensionally measurable (\> 1 cm) extranodal lesion, as measured on CT scan
* Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2

Exclusion Criteria

* Prior enrollment in Study GO41944 (STARGLO; NCT04408638)
* Participant has failed only one prior line of therapy and is a candidate for stem cell transplantation
* History of transformation of indolent disease to DLBCL
* High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements, and high-grade B-cell lymphoma NOS, as defined by 2016 WHO guidelines
* Primary mediastinal B-cell lymphoma
* History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies (or recombinant antibody-related fusion proteins) or known sensitivity or allergy to murine products
* Prior treatment with glofitamab or other bispecific antibodies targeting both CD20 and CD3
* Prior treatment with gemcitabine or oxaliplatin
* Peripheral neuropathy or paresthesia assessed to be Grade \>/= 2 according to NCI CTCAE v5.0 at enrollment
* Treatment with radiotherapy, chemotherapy, immunotherapy, immunosuppressive therapy, or any investigational agent for the purposes of treating cancer within 2 weeks prior to first study treatment
* Treatment with monoclonal antibodies for the purposes of treating cancer within 4 weeks prior to first study treatment
* Primary or secondary CNS lymphoma at the time of recruitment or history of CNS lymphoma
* Prior CNS involvement that has been definitively treated and confirmed via MRI or cerebrospinal fluid analysis to be in complete remission is permissible
* Current or history of CNS disease, such as stroke, epilepsy, CNS vasculitis, or neurodegenerative disease
* History of other primary malignancy, with exceptions defined by the protocol
* Significant or extensive cardiovascular disease, or significant pulmonary disease
* Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (exclusing fungal infections of nail beds) at study enrollment or any major episode of infection within 4 weeks prior to the first study treatment
* Documented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection within 6 months of first study treatment, or positive SARS-CoV-2 test within 7 days prior to enrollment
* Suspected or latent tuberculosis
* Positive test results for hepatitis B (HBV) or hepatitis C (HCV)
* Known or suspected chronic active Epstein-Barr viral infection

* Prior solid organ transplantation
* Prior allogenic stem cell transplant
* Active autoimmune disease requiring treatment
* Prior treatment with systemic immunosuppressive medications within 4 weeks prior to first dose of study treatment
* Ongoing systemic corticosteroid use which, in the opinion of the investigator, puts the patient at increased risk of steroid-related iatrogenic adrenal insufficiency
* Recent major surgery (within 4 weeks before the first study treatment) other than for diagnosis
* Clinically significant history of cirrhotic liver disease
