NCT04941716 | RECRUITING | Recurrent Chronic Lymphocytic Leukemia

Acalabrutinib in Combination With Venetoclax for the Treatment of Refractory or Recurrent Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma, The AVENUE-2 Trial
Sponsor:

Fred Hutchinson Cancer Center

Brief Summary:

This phase II trial is to evaluate the effects of acalabrutinib in combination with venetoclax in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma that does not respond to treatment (refractory) or that has come back (recurrent). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Given acalabrutinib and venetoclax may kill more cancer cells.

Phase

PHASE2

Detailed Description:

OUTLINE: Patients receive acalabrutinib orally (PO) twice a day (BID) and venetoclax PO once daily (QD) on days 1-28. Patients receive acalabrutinib alone for the first three 28 day cycles. Venetoclax is added beginning with Cycle 4. Treatment repeats every 28 days for up to 26 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo blood sample collection, bone marrow aspiration and biopsy, and computed tomography (CT) or magnetic resonance imaging (MRI) throughout the trial. After completion of study treatment, patients are followed-up every 12 weeks and annually for 10 years.

Inclusion Criteria

    • * Massive nodes (\> 10 cm in longest diameter), or progressive or symptomatic lymphadenopathy
    • * Progressive lymphocytosis with an increase of \> 50% over a 2-month period or lymphocyte-doubling time of \< 6 months. Lymphocyte-doubling time may be obtained by linear regression extrapolation of absolute lymphocyte counts obtained at intervals of 2 weeks over an observation period of 2 to 3 months. In patients with initial blood lymphocyte counts of \< 30 x 109/L lymphocyte-doubling time should not be used as a single parameter to define treatment indication. In addition, factors contributing to lymphocytosis or lymphadenopathy other than CLL/SLL (e.g., infection) should be excluded.
    • * Constitutional symptoms, defined as any 1 or more of the following disease-related symptoms or signs
    • * Unintentional weight loss of \> 10% within the previous 6 months
    • * Significant fatigue
    • * Fevers \> 100.5 degrees Fahrenheit (F) or 38 degrees Celsius (C) for 2 weeks without other evidence of infection
    • * Night sweats for \> 1 month without evidence of infection
    • * Relapsed or refractory to at least 1 prior systemic therapy for CLL/SLL. A line of therapy is defined as completing at least 2 cycles of treatment of standard regimen according to current National Comprehensive Cancer Network (NCCN) guidelines, or of an investigational regimen on a clinical trial.
    • * Absolute neutrophil count (ANC) \>= 750 cells/microliter (0.75 x 10\^9/L); ANC \>= 500 cells/microliter (0.50 x 10\^9/L) in subjects with documented bone marrow involvement of CLL (independent of growth factor or transfusion support within 1 week of screening).
    • * Hemoglobin \>= 10 g/dL (independent of growth factor or transfusion support within 1 week of screening).
    • * Platelet count \>= 50,000 cells/microliter (50 x 10\^9/L); platelet count \>= 25,000 cells/microliter (25 x 10\^9/L) in subjects with documented bone marrow involvement of CLL (independent of growth factor or transfusion support within 1 week of screening).
    • * Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =\< 2.5 x upper limit of normal (ULN)
    • * Total bilirubin =\< 2 x ULN, unless directly attributable to Gilbert's syndrome
    • * Estimated creatinine clearance of \>= 50 mL/min
    • * Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
    • * Women of childbearing potential (WOCBP) who are sexually active must use highly effective methods of contraception during treatment and for 30 days after the last dose of acalabrutinib or venetoclax, whichever occurs later
