Inclusion criteria

Age: ≥ 18 years old; Gender unlimited
Pathologically confirmed, relapsed or refractory non Hodgkin's lymphoma (NHL). The definition of recurrence and refractory is as follows: Recurrence: After achieving remission, NHL meets the conditions for disease progression. For B-NHL patients, they should undergo a two line drug treatment regimen (with the first line containing CD20 monoclonal antibody), or a second line systemic treatment regimen that is not suitable/tolerated (such as toxic side effects, etc.); For T-NHL, first-line systemic chemotherapy should be administered, or if systemic chemotherapy is intolerant, and a regimen containing targeted CD30 drugs (including but not limited to Vibutuximab) or cetuximab should be administered. Refractory: Systemic medication treatment with at least two regimens and a total course of no less than 4 cycles of dose standard has not achieved partial remission.
Only limited to stage IIa, pathologically diagnosed, relapsed or refractory follicular lymphoma, peripheral T-cell lymphoma, and diffuse large B-cell lymphoma, with recurrence and refractory defined according to inclusion criteria 2: Cohort 1: Follicular lymphoma (EZH2 mutant): Subjects whose genetic testing results showed the presence of EZH2 gene mutations; If the subject is unable to provide previous genetic testing results or there is no EZH2 gene mutation information in the previous genetic testing results, tumor tissue samples or bone marrow samples (only for subjects with bone marrow invasion) and blood samples must be provided. Only after confirming the presence of EZH2 gene mutations in the central laboratory can they be included in this queue; Cohort 2: Follicular lymphoma (EZH2 wild-type): subjects whose genetic testing results showed no EZH2 gene mutations; If the subject is unable to provide previous genetic testing results or there is no EZH2 gene mutation information in the previous genetic testing results, tumor tissue samples or bone marrow samples (only for subjects with bone marrow invasion) and blood samples must be provided. Only after confirmation by the central laboratory that there is no EZH2 gene mutation can they be included in this queue; Cohort 3: Peripheral T-cell lymphoma, according to the 2016 WHO classification of lymphoid tissue tumors; Cohort 4: Diffuse large B-cell lymphoma;
At least one measurable lesion should be used as the evaluation basis
During the dose escalation phase, subjects should provide tumor tissue samples or bone marrow samples (limited to subjects with bone marrow invasion) and oral swabs (control samples) as much as possible. If tumor tissue or bone marrow samples cannot be provided, they can be included in the study after evaluation by the researcher, provided that they meet other inclusion criteria;

The functional reserve of important organs meets the following requirements: (1) Hematopoietic function: a) Absolute neutrophil count (ANC) ≥ 1.0 × 10^9/L (≥ 0.5 × 10^9/L for those with bone marrow infiltration) (G-CSF was not used within one week before the screening period blood routine examination, and long-acting white needle was not used within two weeks); b) Platelet count ≥ 75 × 10^9/L (≥ 50 × 10^9/L for those with bone marrow infiltration) (no platelet transfusion or TPO receptor agonist used within one week before the screening period blood routine examination); c) Hemoglobin ≥ 90 g/L (bone marrow infiltration requires ≥ 70 g/L) (no red blood cells were transfused or EPO was used within one week before the screening period blood routine examination); (2) Liver function: serum total bilirubin ≤ 1.5 x ULN (Gilbert's syndrome ≤ 3 ULN), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN, ALT/AST ≤ 5 x ULN for patients with liver infiltration, and alkaline phosphatase ≤ 5 x ULN for patients with liver and/or bone infiltration; (3) Renal function: serum creatinine ≤ 1.5 × ULN or creatinine clearance rate estimated based on Cockcroft Gault formula ≥ 60 mL/min (Cockcroft Gault formula, see Appendix 5 for details); (4) Left ventricular ejection fraction (LVEF) ≥ 50%; (5) International standardized ratio (INR) or plasma prothrombin time (PT) ≤ 1.5 x ULN, partial thromboplastin time (APTT) ≤ 1.5 x ULN.
Non surgical sterilization or female patients of childbearing age, as well as male subjects whose partners are female of childbearing age, are required to use a medically approved contraceptive measure (such as an intrauterine device, contraceptive pill, or condom) within 6 months after the screening period and the end of the study treatment period; Non surgically sterilized female patients of childbearing age must have a negative serum HCG test within 7 days prior to enrollment in the study, and must be non lactating;
Prior to conducting research specific procedures, provide a written informed consent form with a signature and date, and be able to comply with clinical visits and research related procedures.
