Zanubrutinib and Venetoclax in CLL (ZANU-VEN)
- Conditions
- Small Lymphocytic Lymphoma (SLL)Chronic Lymphocytic Leukemia (CLL)
- Interventions
- Registration Number
- NCT05168930
- Lead Sponsor
- Dana-Farber Cancer Institute
- Brief Summary
This study is being done to test the effectiveness of zanubrutinib in combination with venetoclax in participants with previously treated chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
- Detailed Description
This is an open-label, non-randomized phase 2 trial assessing the combination of zanubrutinib and venetoclax in adult participants with CLL or SLL who have relapsed after at least one prior therapy.
Participants will receive study treatment for 15 months initially. There is an option for an additional 12 months of re-treatment with study therapy at the time of disease recurrence. Participants will be followed for 36 months after they discontinue the study drugs.
The study will enroll up to 45 participants. BeiGene Ltd. is providing funding for the trial and the study drug zanubrutinib.

Not provided
-
Known BTK C481X mutation.
-
For enrollment to Cohort B: participants who have received prior treatment with both a BTK inhibitor and BCL-2 inhibitor.
-
Participants who have had previous anti-cancer therapy (e.g., chemotherapy, radiotherapy, immunotherapy, biologic therapy, hormonal therapy, surgery, investigational agents, and/or tumor embolization) within 2 weeks of Cycle 1 Day 1 with the following exceptions:
-
Hormonal therapy given in the adjuvant setting
-
Corticosteroid therapy (prednisone or equivalent ≤ 20 mg daily) is allowed as clinically warranted as long as the dose is stabilized at least for 7 days prior to initial dosing. Topical, inhaled, intra-articular, or ophthalmologic corticosteroids are permitted
-
Participants enrolling to Cohort C may remain on prior BTK inhibitor therapy up until 2 days prior to Cycle 1 Day 1
-
History of a prior allogeneic hematologic stem cell transplant.
-
Participants with known central nervous system (CNS) involvement, because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Participants with no known history of CNS involvement are not required to undergo CT scan or lumbar puncture (LP) for trial eligibility unless the participant is symptomatic as judged by the treating investigator.
-
Participants who are receiving any other investigational agents at the time of study entry.
-
History of other malignancies, with the following exceptions:
- Malignancy treated with curative intent and with no known active disease present for ≥ 2 years before the first dose of study drug and felt to be at low risk for recurrence by treating physician
- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
- Adequately treated carcinoma in situ without evidence of disease
- Low-risk prostate cancer on active surveillance
-
Participants who have been vaccinated with live, attenuated vaccines < 4 weeks prior to Cycle 1 Day 1.
-
Recent infection requiring intravenous antibiotics completed ≤ 7 days before the first dose of study drug, or any uncontrolled active systemic infection.
-
Known bleeding disorders (e.g. von Willebrand's disease) or hemophilia.
-
History of stroke, intracranial hemorrhage, or recent major bleed within 6 months prior to study entry.
-
Participants who require warfarin or other vitamin K antagonists for anticoagulation (other anticoagulants are allowed with approval from the overall principal investigator).
-
Participants who are known at the time of study entry to require concomitant treatment with any medications or substances that are moderate or strong CYP3A inhibitors or inducers. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the participant will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the participant is considering a new over-the-counter medicine or herbal product.
-
Known history of human immunodeficiency virus (HIV), active hepatitis C virus (HCV), or hepatitis B virus (HBV).
-
History of allergic reactions attributed to compounds of similar chemical or biologic composition to zanubrutinib or venetoclax.
-
Participants with psychiatric illness/social situations that would limit compliance with study requirements.
-
Pregnant women are excluded from this study because zanubrutinib and venetoclax are anti-cancer agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with zanubrutinib or venetoclax, breastfeeding should be discontinued if the mother is treated with zanubrutinib or venetoclax.
-
Participants with malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel, symptomatic inflammatory bowel disease or ulcerative colitis, or partial or complete bowel obstruction.
-
Currently active, clinically significant cardiovascular disease, such as uncontrolled arrhythmia or Class 3 or 4 congestive heart failure as defined by the New York Heart Association Functional Classification; or a history of myocardial infarction, unstable angina, or acute coronary syndrome within 6 months prior to study entry.
-
Any life-threatening illness, medical condition, or organ system dysfunction that, in the treating investigator's opinion, could compromise the participant's safety or the integrity of the trial.
-
Active and/or ongoing autoimmune anemia and/or autoimmune thrombocytopenia.
