The main organ functions met the following criteria within 7 days before treatment: Blood routine examination criteria: platelet ≥30×10^9/L; Biochemical tests should meet the following criteria: Total bilirubin (TBIL) ≤1.5 times the upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase AST≤2.5*ULN; Creatinine clearance rate ≥ 30mL /min; Cardiac Doppler ultrasonography: Left ventricular ejection fraction (LVEF)≥ the lower limit of normal (50%).
• 8. Both men and women of reproductive age agreed to use reliable contraception throughout the study period and for up to four weeks after the end of treatment
• 9. Life expectancy ≥ 6 months
• 10. Patients voluntarily participated in the study and signed informed consent

Exclusion Criteria:

• 1. Have been diagnosed or treated for malignancies other than CLL (including active CNS lymphoma) within the past year
• 2. Clinical evidence suggests that Richter's transformation occurs
• 3. Non-lymphoma-related liver and kidney function impairment: ALT > 3 times the upper limit of normal value, AST > 3 times the upper limit of normal value, TBIL > 2 times the upper limit of normal value, serum creatinine clearance <30ml/min
• 4. Other serious medical conditions, such as uncontrolled diabetes, gastric ulcers, and other serious heart and lung diseases, may affect this study. The right to make judgments belongs to the researcher
• 5. Diagnosed human immunodeficiency virus (HIV) infection or active hepatitis B virus (HBV) infection, or any uncontrolled active systemic infection requiring intravenous antibiotics.
• (Note: Active HBV infection was defined as a.HBV DNA quantification ≥2000 IU/ mL; b. ALT≥2 times normal upper limit; c. To exclude hepatitis caused by other causes, such as the disease itself or drugs, the three conditions must be met simultaneously. Patients with active HBV infection at initial diagnosis and non-active HBV infection after anti-HBV treatment can be included in this study on the premise of adequate anti-HBV treatment.)
