简要总结
The goal of this clinical research study is to learn if the combination of zanubrutinib, sonrotoclax, and obinutuzumab can help to control previously untreated CLL/SLL.
详细描述
Primary Objective:
1. To evaluate the therapeutic activity, measured by U-MRD4 rate (assessed by clonoSEQ assay) in the bone marrow after cycle 15 of the combination of zanubrutinib, sonrotoclax, and obinutuzumab in patients with previously untreated CLL/SLL.
Secondary Objectives:
- To evaluate the therapeutic activity of the combination of zanubrutinib, sonrotoclax, and obinutuzumab by determining the overall response rate (defined as CR/CRi/PR) and U-MRD5/UMRD6 rate.
- To evaluate progression free survival (PFS).
- To evaluate overall survival (OS).
- To determine the safety and tolerability of the combination of zanubrutinib, sonrotoclax, and obinutuzumab.
- To determine the U-MRD4 rate, PFS, and OS in patients with unmutated IGHV, del(17p) and/or TP53 mutation
- To determine time to next treatment after discontinuation of combination of zanubrutinib, sonrotoclax, and obinutuzumab.
- To determine time to achievement of U-MRD4 with the combination of zanubrutinib, sonrotoclax, and obinutuzumab.
- To determine the rate of U-MRD4 conversion (achievement of U-MRD4 from detectable MRD) with the addition of obinutuzumab from cycle 10 in patients who had detectable MRD4 in bone marrow or peripheral blood at the end of cycle 9.

入选标准
- •Patients with a diagnosis of previously untreated CLL/SLL meeting iwCLL 2018 indication for treatment (Note: patients who receive steroids and/or CD20 mAb for cytoreduction in those patients presenting with significantly elevated WBC count or significant adenopathy/organomegaly and those who previously received steroids/CD20 mAb for immune cytopenias are eligible to enroll; Washout of 3 months applies for CD20 mAb and dose of prednisone (or equivalent) should be less than 20 mg/day by day 1 of study initiation)
- •Age greater than or equal to 18 years of age
- •Eastern Cooperative Oncology Group (ECOG) Performance status of 0-2
- •Adequate hepatic function a. Total bilirubin ≤1.5 x upper limit of normal (ULN) or ≤3 x ULN for patients with Gilbert's disease or documented disease involvement of liver (In pts with elevated total bilirubin due to increased indirect bilirubin, pts with direct bilirubin ≤1.5 x ULN are eligible) b. ALT and AST ≤3.0 x ULN, or ≤5.0 x ULN if documented disease involvement of liver
- •Adequate renal function a. Adequate renal function defined by a value ≥30 mL/min determined via estimated GFR calculated according to the CKD-EPI equation
- •Adequate hematologic function
- •a. Platelet count ≥50 x109 /L and hemoglobin ≥8 g/dL (≥80 g/L). Platelet and hemoglobin requirements are independent of transfusions within 7 days of screening assessment and first dose of study drugs.
- •b. Absolute neutrophil count ≥0.75 x 109 /L. Absolute neutrophil count is independent of growth factor support within 7 days of screening assessment and first dose of study drugs.
- •Adequate coagulation function a. INR ≤1.5 x ULN and aPTT ≤1.5 x ULN
- •Ability to swallow tablets and comply with outpatient treatment, laboratory monitoring, and required clinic visit for the duration of study participation
- •Women of childbearing potential must have a negative serum or urine beta human chorionic gonadotropin (β-hCG) pregnancy test result within 24 hours prior to the first dose of study drugs and must agree to use an effective contraception method (combined hormonal contraception, progestogenonly hormonal contraception associated with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion, or vasectomized partners) during the study and for at least 18 months following the last dose of study drug. Women of non-childbearing potential are those who are postmenopausal greater than 2 year or who have had a bilateral tubal ligation or hysterectomy. Men who have partners of childbearing potential must agree to use an effective contraceptive method (condom or vasectomy) during the study and for at least 18 months following the last dose of study drug. Egg and sperm donation should be refrained for at least 18 months from the last dose of study drug, respectively.
排除标准
- •1. Major surgery within 4 weeks prior to the first dose of study drugs
- •Uncontrolled active systemic infection
- •Known positive serology for human immunodeficiency virus (HIV)
- •Active hepatitis B infection (defined as the presence of detectable HBV DNA, HBe antigen or HBs antigen). Patients with serologic evidence of prior vaccination (HBsAg negative, anti-HBs antibody positive, anti-HBc antibody negative) are eligible. Patients who are HBsAg negative/HBsAb positive but HBcAb positive are eligible, provided HBV DNA is negative and they are willing to take appropriate antiviral prophylaxis
- •Active hepatitis C infection (defined as detectable hepatitis C RNA in plasma by PCR)
- •Known active cytomegalovirus (CMV) infection. Unknown or negative status are eligible
- •Active, uncontrolled autoimmune phenomenon (autoimmune hemolytic anemia or immune thrombocytopenia) requiring steroid therapy with >20 mg daily of prednisone or equivalent
- •Clinically significant, uncontrolled cardiovascular disease (≥3 NYHA heart failure, uncontrolled or symptomatic arrhythmias), or myocardial infarction within 6 months, or stroke within 6 months, or intracranial bleeding within 6 months prior to start of study drugs
- •Uncontrolled hypertension defined as 2 consecutive systolic blood pressure ≥160 mmHg and /or diastolic blood pressure ≥100 mmHg within 3 months
- •History of Mobitz II second degree or third-degree heart block without a permanent pacemaker in place
- •Prolongation of the QT interval corrected for heart rate (QTcF) >480 msec. Note: Patients with QTcF >480 msec should have EKG repeated. If QTcF again is >480 msec, then the patient should be referred to cardiology for evaluation. Patients can be enrolled later if cleared by cardiology and repeat QTcF less than 480 msec. QTcF is calculated using Fridericia's Formula (QTcF): QTcF = QT/(RR0.33)
