Cohort 1 Indications：Relapsed/refractory follicular lymphoma (FL, Grade 1-3a), 2 L； Inclusion Criteria：1）Histopathologically diagnosed CD20-positive FL Failure after first line treatment with regimens containing anti-CD20 monoclonal antibody monotherapy or in combination； Cohort 2 Indications：Relapsed/refractory marginal zone lymphoma (MZL), 2L

Classification of MZL:

• Splenic MZL

• Lymph node MZL Extramodal (MALT) Inclusion Criteria：1）Histopathologically diagnosed CD20-positive MZL Failure after first line treatment with regimens containing anti-CD20 monoclonal antibody monotherapy or in combination Cohort 3 Indications：Relapsed/refractory diffuse large B-cell lymphoma (DLBCL), 2 L Note: Including DLBCL transformed by follicular lymphoma Inclusion Criteria：1）Histopathologically diagnosed CD20-positive DLBCL Failure after first line treatment with regimens containing anti-CD20 monoclonal antibody monotherapy or in combination Note: Relapse is defined as disease progression after response (CR or PR) with adequate treatment, and at least one regimen containing anti-CD20; refractory is defined as failure to achieve a response after adequate treatment with regimen containing anti-CD20, or disease progression (PD or SD) during treatment/within 6 months after completion of adequate treatment.
