Subjects with DLBCL transformed from indolent lymphoma (except for Richter's transformation) are eligible. * Subjects must have progressive disease following at least two (2) lines of prior systemic therapy for DLBCL; prior treatment must have included an anthracycline and rituximab (or another CD20-targeted agent). * Subjects must have failed or be ineligible for ASCT or CAR-T * Have at least one bi-dimensionally measurable lesion per Lugano (2014) * Willing to provide pre-treatment and on-treatment tumor biopsy tissue. * Meet protocol-specified laboratory requirements * Life expectancy \> 3 months. Key Exclusion Criteria: * Primary CNS lymphoma or active secondary CNS involvement and/or lymphomatous meningitis * Chemotherapy, immunotherapy, major surgery, or investigational agent treatment within 28 days of D0 or 5 half-lives, whichever is shorter * Radiotherapy within 14 days of day 0 * Autologous stem cell transplant (ASCT) within ˂100 days prior to D0 * Chimeric antigen receptor T cell (CAR-T) therapy within ˂28 days prior to D0 * Diagnosis of immunodeficiency disorder or history of active autoimmune disease that has required systemic treatment in the past 2 years * Uncontrolled significant active infections (controlled Hepatitis B, Hepatitis C, or HIV may be eligible) * Prior history of malignancy other than eligible lymphoma sub-types, unless the subject has been free of the disease for ≥ 2 years prior to the start of study treatment
