Inclusion criteria

Inclusion criteria: 1. Male or female patients aged 18 years or older; 2. Be able to sign informed consent form voluntarily and understand the study, including the purpose and the procedure and be able to comply with protocol requirements; 3. Patient populations: Dose Escalation: a. Aggressive NHL (aNHL) : MCL, each subtype of DLBCL and FL3b, PMBCL, high level of B cell lymphoma, etc. b. Indolent NHL (iNHL) : including FL1-3 a grade, MZL, small lymphocytic lymphoma, etc. c. all NHL patients should must: relapsed after or failed to respond to at least two prior systemic treatment regimens, including at least one containing an anti-CD20-directed therapy,received or be ineligible for autologous SCT, , there is no other standard treatment is thought to have clinical benefit Dose Expansion: Cohort 1: FL patients who are refractory to or relapsed after = 2 prior regimens and have no other standard of care with clinical benefit. Cohort 2: r/r DLBCL patients who have progressed after or refractory to 2 or more lines of systemic therapy and have not received prior therapy with CAR-T, and do not have standard treatment with clinical benefit. Cohort 3: r/r DLBCL patients who have progressed after or refractory to 2 or more regimens which consisted of a CAR-T therapy that has been approved by a health authority, do not have standard treatment with clinical benefit. 4. NHL patients must have expression of CD20 and/or CD19-expression as determined by immunohistochemistry (IHC) at a certified laboratory within 6 months before study entry without intervening treatment of NHL, otherwise a fresh biopsy must be obtained to determine if CD19 and/or CD20 continue to be expressed by tumor cells. 5. = 1 measurable target lesion as defined by Lugano 2014 criteria (= 15 mm in its largest dimension for nodal lesions or= 10 mm in its largest dimension for extranodal lesion). 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1; Life expectancy> 3 months. 7. Subjects with fertility must take effective contraceptive measures after signing the ICF until at least 12 months after the last administration of 1A46. 8. Clinical laboratory values as specified below during the screening period. ? Total bilirubin must be 50 mL/min (the Cockcroft-Gault formula). ? Hemoglobin (Hb) must be = 80 g/L. No transfusion of red blood cells or use of hematopoietic stimulating factors such as TPO within 14 days before the study. ? Neutrophil count must be >1.0×109/L, No granulocyte or granulocyte macrophage colony-stimulating factor and other hematopoietic stimulating factors were used within 14 days before the study. ? Platelet count must be >75×109/L, No platelet transfusion or use of hematopoietic stimulating factors such as TPO and IL-11 within 14 days prior to testing. ? Prothrombin time-international normalized ratio (PT-INR) must be = 1.5. Patients who are appropriately anticoagulated for a preexisting medical condition [e.g., atrial fibrillation] may be eligible with documented and evaluated by investigators and sponsor approval. 9.
