No prior anti-tumor therapy, such as chemotherapy, radiotherapy, immunotherapy or biotherapy (tumor vaccine, cytokine, or growth factor controlling cancer). there must be at least one evaluable or measurable lesion that meets Lugano2014 criteria (evaluable lesion: PET/CT examination showing increased uptake in lymph nodes or extratodal areas (higher than liver) and PET/CT and/or CT features consistent with lymphoma; Measurable lesions: nodular lesions >15mm in length or extragendal lesions >10mm in length with increased FDG uptake). Adequate organ and bone marrow function, no serious hematopoietic dysfunction, abnormal heart, lung, liver, kidney function and immune deficiency (no blood transfusion, granulocytic colony stimulating factor or other relevant medical support within 14 days prior to the use of the study drug) : A) Blood routine: neutrophil absolute count (ANC) ≥1.5×109/L (1500/mm3), platelet ≥75×109/L, hemoglobin ≥100g/L (if bone marrow is involved, platelet ≥50×109/L, ANC ≥1.0×109/L, hemoglobin ≥80g/L). B) Liver function: serum bilirubin ≤2.5 times the upper limit of normal value, aspartate aminotransferase (AST) and alanine aminotransferase (ALT)≤2.5 times the upper limit of normal value (AST is allowed if liver is involved, ALT≤5 times the upper limit of normal value). C) Renal function: creatinine clearance ≥60 mL/min (estimated according to the Cockcroft-Gault formula). D) Coagulation function: INR≤1.5 times the upper limit of normal value; PT and APTT≤1.5 times the upper limit of normal value. Left ventricular ejection fraction (LVEF) ≥ 50% in cardiac function examination. Male subjects used effective contraception from signing informed consent until 6 months after the last chemotherapy. Life expectancy > 3 months. Exclusion Criteria: The diagnosis was leukemic mantle cell lymphoma. Central nervous system involvement secondary to lymphoma. history of other active malignant diseases within 2 years prior to study entry, but eligibility for inclusion :(1) adequately treated carcinoma in situ of the cervix; (2) local basal cell carcinoma or squamous cell carcinoma of skin; (3) Pre-existing malignant disease that is under control and has undergone local radical treatment (surgical or other forms). People with a known history of Human Immunodeficiency Virus (HIV) infection and/or acquired Immunodeficiency syndrome. Screening stage of hepatitis b surface antigen or hepatitis c virus antibody positive patients, must further by hepatitis b virus DNA (no more than 1000 iu/ml) and HCV RNA detection (shall not exceed the method detection limit), in the activity of the ruled out the need for treatment after hepatitis b or hepatitis c infection, before the experiment. Patients with hepatitis B virus carriers, stabilized hepatitis B after drug treatment and cured hepatitis C can be included. Major surgery was performed within 28 days prior to study initiation. Any active infections, including but not limited to bacterial, fungal or viral infections, that require systemic antiinfective therapy within 14 days prior to initiation of treatment. combined with severe or uncontrolled disease, including but not limited to symptomatic of congestive heart failure, uncontrolled hypertension, unstable angina, active peptic ulcer or A history of severe hemorrhagic diseases, such as hemophilia a., hemophilia B, von willebrand disease or blood transfusion or other medical intervention history of spontaneous bleeding. History of stroke or intracranial hemorrhage within 6 months prior to first administration of the study drug. A history of deep vein thrombosis (DVT) or pulmonary embolism (PE) within the past 12 months. Patients who must take antiplatelet drugs and anticoagulant drugs at the same time due to underlying diseases and have no alternative treatment plan. Continuous treatment with strong and moderate CYP3A inhibitors or CYP3A inducers is required. Patients were excluded if they had taken a CYP3A potent or moderate-acting inhibitor or inducer within 7 days prior to the first administration of the study drug (or had taken these drugs for less than 5 half-lives). Patients deemed unsuitable for the study by other investigators.
