A Clinical Study Exploring CT1190B in the Treatment of Patients With Relapsed/Refractory B-cell Non-Hodgkin Lymphoma ( CT1190B-CG11001 )

1. Participants must voluntarily sign the informed consent form (ICF) and must be willing and be able to adhere to the study visit schedule and other protocol requirements and agree to be in long term follow-up (LTFU) for up to 15 years as mandated by the regulatory guidelines.

2. 18-75 years old;

3. Histologically or cytologically confirmed B-NHL, according the 5th edition of the WHO classification of haematolymphoid tumours, including:

1\) Cohort A1: Large B-cell lymphoma, including diffuse large B-cell lymphoma not other specified (DLBCL, NOS), primary mediastinal large B-cell lymphoma (PMBCL), high-grade B-cell lymphoma, transformed follicular large B-cell lymphoma (FLBL)/Grade 3b follicular lymphoma ( FL) ; 2) Cohort A2: Mantle cell lymphoma (MCL); 3) Cohort B1: Grade 1 \~ 3a FL; 4) Cohort B2: chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) according to iwCLL2018 diagnose criteria , with the exception of participants who are currently transformed into Richter 's syndrome; 5) Cohort C:Primary central nervous system lymphoma （PCNSL). 4. Previous treatment requirement:

1. Cohort A1: Previously received at least 2 lines of systemic therapy, including anti-CD20 drugs (unless the investigator had determined that the tumor is/is CD20 negative) and anthracycline containing regimens, anti-CD20 drugs maintenance alone will not be counted as 1 line of treatment; for participants with transformed FL (FLBL), any treatment administered prior to transformation will not be counted as a prior line.

2. Cohort A2: at least 2 prior lines of systemic therapy, including anthracycline or bendamustine-containing chemotherapy, anti-CD20 drugs ( unless the investigator had determined that the tumor is/is CD20 negative) and a BTK inhibitor; and CD20 monoclonal antibody alone will not be count as 1 line of treatment;

3. Cohort B1: previously received at least 2 lines of systemic therapy, including anti-CD20 drugs ( unless the investigator had determined that the tumor is/is CD20 negative) and anthracycline-containing chemotherapy regimens, and CD20 monoclonal antibody alone will not be counted as 1 line of treatment;

4. Cohort B2: at least 2 prior lines of therapy, including immunotherapy or chemotherapy and a BTK inhibitor, or BTK inhibitor who are not suitable for immunotherapy or chemotherapy.

5. Cohort C:at least 1 line of therapy, including MTX based chemotherapy. 5. Intolerance to last treatment, or have progressed on or after the last treatment and currently require therapy.

6\. At least one of the following:

1\) CT or MRI testing: Intranodal lesions \> 1.5 cm in long diameter, or Extranodal lesions \> 1.0 cm in long diameter; 2)PET-CT testing: \[18F\] fluorodeoxyglucose (FDG) positron emission tomography (PET) positive lesion per Lugano criteria at screening (Deauville score 4 or 5); 3) CLL participants requiring treatment according to iwCLL criteria (refer to Appendix 4); 7. Expected survival \> 12 weeks; 8. Eastern Cooperative Oncology Group (ECOG) score 0-1,PCNSL ECOG score: 0\~3; 9. Participants should meet the following test results

1. CBC: # platelet (PLT) ≥ 75 × 10 9/L (for participants with bone marrow or peripheral blood involvement: PLT ≥ 50 × 10 9/L), #hemoglobin (Hb) ≥ 80 g/L (for participants with bone marrow or peripheral blood involvement: Hb ≥ 60 g/L);

2. Endogenous creatinine clearance ≥ 30 mL/min (using the Cockcroft -Gault formula);

3. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × ULN and total bilirubin ≤ 1.5 × ULN ; if there is liver involvement: AST and ALT ≤ 5 × ULN and total bilirubin ≤ 3.0 × ULN ;

4. International normalized ratio (INR) and activated partial thromboplastin time (APTT) ≤ 1.5 × ULN.

10\. Female participants of childbearing potential must have a negative pregnancy test at screening and prior to receiving preconditioning therapy and are willing to use a highly effective and reliable method of contraception for 1 year after receiving study treatment and are absolutely prohibited from donating eggs for 1 year after receiving study treatment infusion during the study; male participants are willing to use a highly effective and reliable method of contraception for 1 year after receiving study treatment if they are sexually active with a female of childbearing potential. Sperm donation is absolutely prohibited for 1 year after receiving study treatment infusions during the study for all male participants.
