Chronic Lymphocytic Leukemia Clinical Trial
— ZFCR/ZBROfficial title:
A Phase 2 Clinical Trial to Evaluate the Efficacy of Zanubrutinib Followed Zanubrutinib Plus FCR (Fludarabine Cyclophosphamide and Rituximab) / BR(Bendamustine and Rituximab) in Newly Diagnosed Symptomatic CLL/SLL (STOP Trial)
This study aims to evaluate the long-term efficacy of BTK inhibitor Zanubrutinib monotherapy , sequential Zanubrutinib combined (Fludarabine, cyclophosphamide and rituximab /bendamustine and rituximab)FCR/BR regimen by a limited period of treatment for the newly diagnosed Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). The investigators propose this combination will improve the MRD negative rate of patients with CR/CRi after treatment was significantly higher than that of FCR chemotherapy can be a time-limited regimen which will reduce the life-time therapy and benefit the patients.

Confirmed diagnosis of CLL or SLL that meets the 2008 IWCLL criteria - 4.

Treatment indications for CLL mainly include (meeting at least one of the following conditions): - a) Evidence of progressive bone marrow failure presenting as progressive decrease in hemoglobin and/or platelets - b) Splenomegaly (e.g., >6cm below the left costal margin) or progressive or symptomatic splenomegaly - c) giant lymph node enlargement (longest diameter >10cm) or progressive or symptomatic lymph node enlargement - d) Progressive lymphocytosis, such as lymphocytosis >50% within 2 months, or lymphocyte multiplication time (LDT) <6 months. When the initial lymphocyte was <30×109/L, LDT alone could not be used as a treatment indication - e) Autoimmune hemolytic anemia (AIHA) and/or immune thrombocytopenia (ITP) do not respond well to corticosteroids or other standard treatments - f) Symptoms associated with at least one of the following diseases: ?=10% weight loss with no apparent cause in the previous 6 months; ? Severe fatigue (such as ECOG physical state =2 points; Unable to carry out regular activities); ?

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.) - 6. Clinical manifestations of central nervous dysfunction or CNS invasion - 7. Patients who have had major surgery (excluding lymph node biopsy) within the past 14 days or who are expected to require major surgery as part of their treatment - 8.Unable to swallow capsules or malabsorption syndrome, disease that significantly affects gastrointestinal function, previous gastrectomy or small bowel resection, symptomatic inflammatory bowel disease or ulcerative colitis, or partial or complete bowel obstruction - 9. Requires ongoing treatment with any medication which is a strong cytochrome P450, family 3, subfamily A (CYP3A) inhibitor or strong CYP3A inducer - 10. Females who are currently pregnant or breastfeeding, or at a childbearing age who are not using contraception - 11. Clinically significant cardiovascular abnormalities (NYHA classification: III/IV) (Annex 3), patients with myocardial infarction, malignant arrhythmia (including QTC=480ms), unsatisfactory blood pressure control with antihypertensive drugs (systolic blood pressure =150 mmHg, diastolic blood pressure =100 mmHg), and uncontrolled angina pectoris within 6 months before enrollment - 12. Persistent uncontrolled bleeding - 13. A history of life-threatening haemorrhage, especially from irreversible causes - 14. High doses of several anticoagulants are required and cannot be stopped for a short time - 15. evere allergy to the active ingredient or any excipients of the product |
