Inclusion Criteria
- Signed Informed Consent Form
- Histologically confirmed large B-cell lymphoma with CD19 and CD20 expression, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS); primary mediastinal large B-cell lymphoma (PMBCL); high-grade B-cell lymphoma (HGBL); and transformed follicular lymphoma

Group Intervention Description CAR T-cell therapy in combination with Glofitamab CAR T-cell therapy After undergoing leukapheresis, participants will receive treatment in the following procedure. Bridging Phase: All participants will receive two cycles of Glofitamab treatment. On Day 1 of Cycle 1, patients will receive 1000 mg of Obinutuzumab as pretreatment. CAR-T Treatment Phase: Participants will receive lymphodepletion therapy with the FLU/CY regimen on Day -5 through Day -3. Participants will receive the CAR T-cell infusion on Day 0. Consolidation Phase: Treatment based on the response assessment at Day 28 after CAR T-cell infusion: participants who attained complete response (CR) at Day 28 will not receive additional Glofitamab treatment, while those attained partial response (PR), stable disease (SD), or progressive disease (PD) will receive additional four cycles of Glofitamab.

- Primary Outcome Measures
Name Time Method Complete Response (CR) Rate Up to 2 years CR rate is defined as the percentage of participants achieving CR per the Lugano Classification as determined by study investigators
- Secondary Outcome Measures
Name Time Method Objective Response Rate (ORR) Up to 2 years ORR is defined as the percentage of participants achieving either CR or partial response (PR) per the Lugano Classification as determined by study investigators
Duration of Response (DoR) Up to 2 years DoR is defined only for participants who experience an objective response and is the time from the first objective response to disease progression or death from any cause.
Progression-Free Survival (PFS) Up to 2 years PFS is defined as the time from leukapheresis to first documented progression or death from any cause.
Overall Survival (OS) Up to 2 years OS is defined as the time from leukapheresis to death from any cause.
Percentage of Participants With Treatment Emergent Adverse Events (TEAEs) Up to 2 years Assessed by CTCAE criteria v5 and ASTCT 2019 criteria for CRS/ICANS adverse events.
