Inclusion Criteria: Participants ≥ 18 years of age with R/R NHL (including DLBCL [ie, DLBCL not otherwise specified (NOS) and diffuse large B-Cell lymphoma/high-grade B-Cell lymphoma with MYC and BCL2 rearrangements], and FL): For R/R DLBCL (de novo) and FL 3b: following at least 2 prior lines of therapy (eg, first-line combination chemotherapy regimen containing rituximab, anthracycline, an alkylating agent, and steroids and at least one additional treatment). For R/R DLBCL (transformed lymphoma): following at least 2 prior lines of therapy which must have been administered after transformation. For R/R FL (except for FL 3b): following at least 2 prior lines of therapy and meeting treatment criteria at the time of enrollment based on investigator´s assessment. Participant must have measurable disease (defined by at least one FDG-avid lesion for FDG-avid disease and one bi-dimensionally measurable disease on cross sectional imaging by computed tomography or magnetic resonance imaging with at least one lesion > 1.5 cm in the transverse diameter). Participants must accept and follow pregnancy prevention plan. Exclusion Criteria: Participants must not have an Eastern Cooperative Oncology Group (ECOG)22 performance status ≥ 3. Participants with an inability to comply with listed restrictions, precautions and prohibited treatments. Participants must not have prior CAR-T, Cereblon-modulating drug or radiotherapy ≤ 4 weeks, systemic anticancer treatment ≤ 5 half-lives or 4 weeks, allogeneic SCT ≤ 6 months or autologous SCT ≤ 3 months prior to study intervention initiation. Participants must not have any condition, including significant acute or chronic medical illness, active or uncontrolled infection, or the presence of laboratory abnormalities, that places participants at unacceptable risk if participating in this study.
