Overview
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).

Inclusion Criteria:
- Histologically confirmed (per local evaluation) diagnosis of de novo, previously untreated large B-cell lymphoma (LBCL) according to 2022 world health organization (WHO) classification including:
i) Diffuse large B-cell lymphoma (DLBCL), not otherwise specified \[including germinal center B-cell (GCB) and activated B-cell (ABC) types\]
ii) High-grade B-cell lymphoma, with MYC and BCL2 rearrangements (HGBL-MYC/BCL2 double-hit lymphomas)
iii) High-grade B-cell lymphoma, not otherwise specified
iv) T-cell/histiocyte/rich large B-cell lymphoma (THRLBCL)
v) Epstein-Barr virus + DLBCL
* International Prognostic Index (IPI) score 1 or 2 with lactate dehydrogenase (LDH) \> 1.3 x upper limit of normal (ULN) and/or bulky disease defined as single lesion of ≥ 7 cm OR IPI ≥ 3.
* Measurable disease defined by at least 1 fluorodeoxyglucose (FDG)-avid lesion for FDG-avid subtype and 1 bi-dimensionally measurable (\> 1.5 cm in longest diameter) disease by computed tomography (CT) or magnetic resonance imaging (MRI), as defined by the Lugano classification.
* Must have Ann Arbor Stage II-IV disease.
Exclusion Criteria:
* Any significant medical condition, active infection, laboratory abnormality, or psychiatric illness that would prevent the participant from participating in the study.
* Any other subtype of lymphoma. Cases of primary mediastinal (thymic) large B-cell lymphoma (PMBCL), primary cutaneous DLBCL-leg type, Grade 3b FL, indolent lymphoma transformed to large B-cell lymphoma (LBCL), Anaplastic lymphoma kinase (ALK) positive large B-cell lymphoma, primary effusion lymphoma, and Burkitt lymphoma.
* Documented or suspected central nervous system (CNS) involvement by lymphoma.
* Other protocol-defined Inclusion/Exclusion criteria apply.
