Inclusion Criteria

• •Women and men between 18 and 75 years old, voluntarily signed a informed consent.
• •Body weight ≥ 45 kg.
• •ECOG (Eastern Cooperative Oncology Group) performance status of 0\~1.
• •Life expectancy (in the opinion of the investigator) of ≥ 4 months.
• •Patients with histologically or cytologically confirmed mature B-cell lymphoma according to 2017 WHO (World Health Organization) classification, including chronic lymphocytic leukemia/ small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma (MCL), follicular lymphoma (FL), marginal zone lymphoma (MZL), Waldenström's Macroglobulinemia (WM) and diffuse large B-cell lymphoma (DLBCL); previous treatment for DLBCL patients must include Rituxan (CD20 monoclonal antibody) and anthracyclines-based therapy and meet one of the following criteria: 1）complete response was not achieved after previous second line therapy; 2) disease progression occurred during any of previous treatment; 3) the duration of stable disease was ≤ 6 months; 4) Disease progression or recurrence occurred within 12 months after autologous hematopoietic stem cell transplantation; CLL and other indolent B-cell NHL patients must meet one of the following criteria: at least failure to respond to first line therapy (SD or PD after treatment with Rituxan-based and alkylating agents or anthracyclines therapy), any response (CR or PR) and progression after stable disease.
• •Measurable disease for SLL, MCL, FL, DLBCL and MZL: lymph node lesions\>1.5 cm diameter in at least one dimension or any of external node lesions \>1.0 cm diameter in at least one dimension; for CLL, peripheral blood monoclonal lymphocytes ≥ 5.0×109/L; for WM, IgM﹥2×ULN (upper limit of normal).
• •Any non-hematologic toxicity associated with prior treatment should recover to grade ≤ 1 (according to NCI CTCAE version 5.0).
• •Adequate hematological function (no blood transfusion, no use of G-CSF (G-Colony stimulating factor) and no drug correction within 14 days of screening): absolute neutrophil count (ANC) ≥ 0.75 × 109 /L (≥ 0.5×109/L if presence of bone marrow infiltration); platelet count ≥ 50 × 109/L; Hgb ≥ 8.0 g/dL (≥7.0 g/dL if presence of bone marrow infiltration for WM and CLL).
• •Adequate renal function: serum creatinine ≤ 1.5 × ULN or estimated creatinine clearance ≥ 60 mL/min (Male: Cr (mL/min) = (140- age) × weight (kg) /72× serum creatinine concentration (mg/dl); Female: Cr (ml/min) = (140- age) × weight (kg) /85× serum creatinine concentration (mg/dl)).
• •Adequate liver function: total serum bilirubin ≤ 1.5 x ULN (≤3.0×ULN if presence of liver metastasis); AST and ALT ≤ 2.5 x ULN (≤5.0×ULN if presence of liver metastasis).
• •Female of childbearing age and males subjects with fertility must practice at least one of the following effective contraception methods throughout the study and within 90 days of discontinuing study drug: total abstinence from sexual intercourse, physical contraception, or hormonal contraceptive initiated at least 3 months prior to first dose of study drug.
• •Male subjects must not donate sperm from initial study drug administration, until 90 days after drug discontinuation.
• •Ability to swallow oral capsules without difficulty.
• •Willing to follow visit schedules, drug administration schedules, laboratory tests and other test procedures.
