Study Arms (3)

Cohort A: BTKi and BCL2i naive

EXPERIMENTAL

Participants who have never received a BTK inhibitor or a BCL-2 inhibitor

Drug: VenetoclaxDrug: Zanubrutinib

Cohort B: BTKi or BCL2i exposed without disease progression

EXPERIMENTAL

Participants who have received prior treatment with a BTK or BCL-2 inhibitor and discontinued treatment for any reason other than disease progression

Drug: VenetoclaxDrug: Zanubrutinib

Cohort C: BTKi exposed and with disease progression

EXPERIMENTAL

Participants who experienced disease progression on a prior BTK inhibitor. Participants with BTK C481X mutation at enrollment will be excluded.

Drug: VenetoclaxDrug: Zanubrutinib

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Confirmed diagnosis of CLL or SLL as per 2018 International Workshop on CLL (IWCLL) criteria.
  • Participants must have relapsed after at least one prior line of therapy and must currently require therapy by 2019 IWCLL criteria.
  • For enrollment to Cohort A: Participants must be covalent BTK and BCL-2 inhibitor naïve. Participants who have received prior therapy with a covalent BTK or BCL-2 inhibitor are not eligible, including but not limited to prior treatment with ibrutinib or acalabrutinib.
  • For enrollment to Cohort B: Participants must have had prior treatment with a BTK inhibitor or a BCL-2 inhibitor, but not both, and must not have experienced disease progression as defined by iwCLL criteria while receiving therapy.
  • For enrollment to Cohort C: participants must have a disease that progressed during therapy with a covalent BTK inhibitor, not including zanubrutinib.
  • Age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of zanubrutinib and venetoclax in participants \< 18 years of age and CLL/SLL is extremely rare in this population, children are excluded from this study.
  • ECOG performance status ≤ 2 (Karnofsky ≥ 60%, see Appendix A).
  • Participants must have adequate organ function as defined below:
  • Platelet count ≥ 20,000/mcL
  • Total bilirubin ≤ 2 × institutional upper limit of normal (ULN) (unless due to controlled hemolysis, Gilbert's disease, or is of non-hepatic origin)
  • AST (SGOT) and ALT (SGPT) ≤ 4 × institutional ULN
  • Serum Creatinine ≤ 1.5 × institutional ULN, OR
  • Calculated creatinine clearance ≥ 50 mL/min (as calculated by the Cockcroft-Gault formula)
  • The effects of zanubrutinib or venetoclax on the developing human fetus are unknown. For this reason and because anti-cancer agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of study agent administration.
  • Ability to understand and the willingness to sign a written informed consent document.
  • +1 more criteria

You may not qualify if:

  • 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.
  • +13 more criteria
