Outcome Measures

Primary Outcomes (1)

  • Progression-free Survival (PFS) Per Independent Review Committee (IRC) Assessment

    To evaluate the efficacy of acalabrutinib monotherapy (Arm A) compared with idelalisib/rituximab or bendamustine/rituximab (Arm B) based on Independent Review Committee (IRC) assessment of progression-free survival (PFS) per International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria (Hallek 2008) with incorporation of the clarification for treatment-related lymphocytosis (Cheson 2012) hereafter referred to as IWCLL 2008 criteria in subjects with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL). As planned and reported in the interim clinical study report (dated 17 July 2019), because the study did cross the boundary at interim analysis. IRC assessments were discontinued after the interim analysis. All IRC-related efficacy analyses in this clinical study report were based on the interim analysis data cutoff date of 15 January 2019. All other efficacy analyses were based on the final analysis data cutoff date of 03 September 2021.

    IRC assessments from randomization date until disease progression or death or IRC discontinuation on 15Jan2019 (as IA per this data cutoff showed crossing superiority boundary) whichever came first, up to 22 months of follow-up

Secondary Outcomes (7)

  • Progression-free Survival (PFS) Per Investigator Assessment

    From randomization date to date of disease progression or death due to any cause or data cutoff date on 03Sep2021, whichever came first, regardless of use of subsequent anticancer therapy, until 53 months of follow-up.

  • IRC-assessed Overall Response Rate (ORR) Per IWCLL 2008 Criteria Based on Data Cutoff 15 January 2019 From Interim Analysis

    IRC assessments from randomization date until disease progression or death or IRC discontinuation on 15Jan2019 (as IA per this data cutoff showed crossing superiority boundary) whichever came first, up to 22 months of follow-up

  • Investigator Assessed Overall Response Rate (ORR) Per IWCLL 2008 Criteria Based on Data Cutoff 03 September 2021

    Investigator assessments were done from randomization date until date of death or date of exit from study or data cut off date on 03Sep2021, whichever came first, up to 53 months of follow-up.

  • Overall Survival (OS)

    From randomization date to date of death due to any cause, or date of study discontinuation, or date of data cutoff on 03Sep2021, whichever came first until 54 months of follow-up.

  • Duration of Response (DOR) Per Independent Review Committee (IRC) Assessment Based on 15 January 2019 Data Cutoff From Interim Analysis.

    IRC assessments from randomization date until disease progression or death or IRC discontinuation on 15Jan2019 (as IA per this data cutoff showed crossing superiority boundary) whichever came first, up to 22 months of follow-up

Eligibility Criteria

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

You may qualify if:

  • Men and women ≥ 18 years of age.
  • ECOG performance status of 0 to 2.
  • Diagnosis of CLL that meets published diagnostic criteria (Hallek 2008):
  • Monoclonal B-cells (either kappa or lambda light chain restricted) that are clonally co-expressing ≥ 1 B-cell marker (CD19, CD20, or CD23) and CD5.
  • Prolymphocytes may comprise ≤ 55% of blood lymphocytes.
  • Presence of ≥ 5 x 10\^9 B lymphocytes/L (5000/μL) in the peripheral blood (at any point since initial diagnosis).
  • Must have documented CD20-positive CLL.
  • Active disease meeting ≥ 1 of the following IWCLL 2008 criteria for requiring treatment:
  • Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia (hemoglobin \< 10 g/dL) and/or thrombocytopenia (platelets \< 100,000/μL).
  • Massive (i.e., ≥ 6 cm below the left costal margin), progressive, or symptomatic splenomegaly.
  • Massive nodes (i.e., ≥ 10 cm in the longest diameter), progressive, or symptomatic lymphadenopathy.
  • Progressive lymphocytosis with an increase of \> 50% over a 2-month period or a LDT of \< 6 months. LDT may be obtained by linear regression extrapolation of ALC obtained at intervals of 2 weeks over an observation period of 2 to 3 months. In subjects with initial blood lymphocyte counts of \< 30 x 10\^9/L (30,000/μL), LDT should not be used as a single parameter to define indication for treatment. In addition, factors contributing to lymphocytosis or lymphadenopathy other than CLL (e.g., infections) should be excluded.
  • Autoimmune anemia and/or thrombocytopenia that is poorly responsive to standard therapy.
  • Constitutional symptoms documented in the subject's chart with supportive objective measures, as appropriate, defined as ≥ 1 of the following disease-related symptoms or signs:
  • i. Unintentional weight loss ≥ 10% within the previous 6 months before screening.
  • +15 more criteria

You may not qualify if:

  • Known CNS lymphoma or leukemia.
  • Known prolymphocytic leukemia or history of, or currently suspected, Richter's syndrome.
  • Uncontrolled AIHA or ITP defined as declining hemoglobin or platelet count secondary to autoimmune destruction within the screening period or requirement for high doses of steroids (\> 20 mg daily of prednisone or equivalent).
  • Prior exposure to a BCL-2 inhibitor (e.g., venetoclax/ABT-199) or a BCR inhibitor (e.g., BTK inhibitors or PI3K inhibitors). Prior bendamustine is allowed if Investigator's choice for treatment in Arm B is idelalisib with rituximab. Bendamustine retreatment is allowed if the prior response to bendamustine lasted \> 24 months.
  • Received any chemotherapy, external beam radiation therapy, anticancer antibodies, or investigational drug within 30 days before first dose of study drug.
  • Corticosteroid use \> 20 mg daily prednisone equivalent within 1 week before first dose of study drug, except as indicated for other medical conditions such as inhaled steroid for asthma, topical steroid use, or as premedication for administration of study drug or contrast. For example, subjects requiring steroids at daily doses \> 20 mg prednisone equivalent systemic exposure daily, or those who are administered steroids for leukemia control or white blood cell count lowering are excluded.
  • Prior radio- or toxin-conjugated antibody therapy.
  • Prior allogeneic stem cell transplant or prior autologous transplant within 6 months of first dose of study drug(s) or presence of graft-vs-host disease or receiving treatment for graft-vs-host disease.
  • Major surgical procedure within 30 days of first dose of study drug. Note: If a subject had major surgery, they must have recovered adequately from any toxicity and/or complications from the intervention before the first dose of study drug.
  • History of prior malignancy except for the following:
  • Malignancy treated with curative intent and with no evidence of active disease present for more than 2 years before screening and felt to be at low risk for recurrence by treating physician.
  • Adequately treated lentigo maligna melanoma without current evidence of disease or adequately controlled nonmelanomatous skin cancer.
  • Adequately treated carcinoma in situ without current evidence of disease.

Exception: Subjects with controlled, asymptomatic atrial fibrillation during screening are allowed to enroll on study.
  • Malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach, or extensive small bowel resection that is likely to affect absorption, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction, or gastric restrictions and bariatric surgery, such as gastric bypass.
