Testing Early Treatment for Patients With High-Risk Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Leukemia (SLL), EVOLVE CLL/SLL Study
Purpose
This phase III trial compares early treatment with venetoclax and obinutuzumab versus delayed treatment with venetoclax and obinutuzumab in patients with newly diagnosed high-risk chronic lymphocytic leukemia or small lymphocytic lymphoma. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Starting treatment with the venetoclax and obinutuzumab early (before patients have symptoms) may have better outcomes for patients with chronic lymphocytic leukemia or small lymphocytic lymphoma compared to starting treatment with the venetoclax and obinutuzumab after patients show symptoms.

     minor surgery within 7 days prior to registration. Examples of major surgery include
     neurosurgical procedures, joint replacements, and surgeries that occur inside the
     thoracic or abdomino-pelvic cavities. Examples of minor surgery include dental
     surgery, insertion of a venous access device, skin biopsy, or aspiration of a joint.
     If a participant has had a bone marrow biopsy for diagnosis or evaluation of CLL,
     this will not exclude the participant from registration to the study. If there is a
     question about whether a surgery is major or minor, this should be discussed with
     the Study Chair
  -  Participants must not have known bleeding disorders (e.g., von Willebrand's disease
     or hemophilia)
  -  Participants must not have a history of stroke or intracranial hemorrhage within 6
     months prior to enrollment
  -  Participants must not require continued therapy with a strong inhibitor or inducer
     of CYP3A4/5, as venetoclax is extensively metabolized by CYP3A4/5
  -  Participants must not have uncontrolled autoimmune hemolytic anemia or idiopathic
     thrombocytopenia purpura
  -  Participants must not have any currently active, clinically significant
     cardiovascular disease, such as uncontrolled arrhythmia or class 3 or 4 congestive

  -  Participants must not have a history of myocardial infarction, unstable angina, or
     acute coronary syndrome within 6 months prior to enrollment
  -  Participants must not be pregnant or nursing, as there are no safety data available
     for these drug regimens during pregnancy. Women/men of reproductive potential must
     have agreed to use an effective contraceptive method. A woman is considered to be of
     "reproductive potential" if she has had menses at any time in the preceding 12
     consecutive months. In addition to routine contraceptive methods, "effective
     contraception" also includes heterosexual celibacy and surgery intended to prevent
     pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy,
     bilateral oophorectomy or bilateral tubal ligation. However, if at any point a
     previously celibate patient chooses to become heterosexually active during the time
     period for use of contraceptive measures outlined in the protocol, he/she is
     responsible for beginning contraceptive measures
  -  Participants must agree to have specimens submitted for translational medicine (MRD)
     as outlined
  -  Participants must be offered the opportunity to participate in specimen banking for
     future research as outlined.
       -  NOTE: With participant's consent, the site must follow through with specimen
          submission as outlined
  -  Participants who are able to complete patient reported outcome (PRO) forms in
     English, Spanish, French, German, Russian or Mandarin must agree to participate in
     the quality of life assessments. (Those participants who are unable to read and
     write in English, Spanish, French, German, Russian or Mandarin may be registered to
     S1925 without contributing to the quality of life portion of the study.)
  -  Participants must be informed of the investigational nature of this study and must
     sign and give written informed consent in accordance with institutional and federal
     guidelines
  -  NOTE: As a part of the Oncology Patient Enrollment Network (OPEN) registration
     process the treating institution's identity is provided in order to ensure that the
     current (within 365 days) date of institutional review board approval for this study
     has been entered in the system

Detailed Description
PRIMARY OBJECTIVE: I. To evaluate whether early treatment with venetoclax and obinutuzumab (V-O) extends overall survival (OS) compared with delayed treatment with V-O in high-risk (Chronic Lymphocytic Leukemia [CLL] International Prognostic Indicator [CLL-IPI] >= 4 or complex cytogenetics), newly diagnosed asymptomatic CLL/small lymphocytic lymphoma (SLL) participants. SECONDARY OBJECTIVES: I. To compare overall response rates (complete response [CR] + partial response [PR]), CR rates, progression-free survival (PFS), and event-free survival (EFS) between arms. II. To evaluate safety and tolerability of each arm. III. To compare time to second CLL-directed treatment (from randomization and from response) between arms. IV. To compare relapse-free survival (RFS) and time to second objective disease progression (PFS2) between arms. V. To compare the rates of Richter's transformation between arms. VI. To describe distribution of Cumulative Illness Rating Scale across the study, in each treatment arm, and to estimate the interaction between the scale and treatment arm and OS. PATIENT-REPORTED OUTCOMES OBJECTIVES: I. To assess the impact of early intervention with V-O versus delayed therapy with V-O in CLL participants in relation to Health-Related Quality of Life (HRQoL) using the Functional Assessment of Cancer Therapy (FACT)-Leukemia scale. II. To assess the impact of the two treatment arms on the specific domains of the FACT-Leukemia, including physical, social, emotional, and functional well-being and leukemia-specific HRQoL. TRANSLATIONAL MEDICINE OBJECTIVES (INTEGRATED): I. To evaluate the prognostic association between OS and measurable residual disease (MRD) undetectable disease state at 15 months after treatment initiation, across and between treatment arms. (Primary) II. To describe the prognostic association between the endpoints RFS and OS and MRD undetectable disease state at all measured time points (cycle [C]7 day[D]1, C9D1, C12D1, and 15, 21, 27, 33, 39, 45, 51, 57, 63, 69, 75, 81, 87, 93, and 99 months after treatment initiation) using landmark analyses, across and between treatment arms. (Secondary) III. To evaluate the prognostic association of MRD undetectable disease state over time in each treatment arm with respect to OS and RFS using time-dependent covariate analyses. (Secondary) IV. To describe the proportion of variation in OS and RFS explained by MRD sampling schemes with the goal of providing information on how much additional variation in OS and RFS is explained by additional MRD sampling for future trial designs. (Secondary) V. To compare the rate of MRD undetectable disease state at 15 months after initiation of treatment between treatment arms. (Secondary) VI. To compare duration of MRD undetectable disease state between treatment arms. (Secondary) VII. To describe associations between pretreatment stimulated karyotype risk, p53 mutation, IGHV mutational analysis, fluorescence in situ hybridization (FISH) for del(13q), del(11q), trisomy 12, and del(17p), and beta-2-microglobulin levels and other biomarkers with OS, PFS, overall and complete response rates, achievement of MRD undetectable disease state, and Richter's transformation. (Secondary) VIII. To describe associations between clinical complete or partial response (by International Workshop on Chronic Lymphocytic Leukemia [IWCLL] 2018 criteria) and response as assessed by MRD status and CT scans at 15 months after treatment initiation. (Secondary) OUTLINE: Patients are randomized to 1 of 2 arms. ARM I (DELAYED V-O): Treatment begins once 2018 IWCLL indications are met. Patients receive obinutuzumab intravenously (IV) over 4 hours on days 1, 2, 8, and 15 of cycle 1 and on day 1 of cycles 2-6. Patients also receive venetoclax orally (PO) once daily (QD) on days 22-28 of cycle 1 and on days 1-28 of cycles 2-12. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo CT, collection of blood samples, and bone marrow aspiration and biopsy throughout the trial. ARM II (EARLY V-O): Treatment begins as soon as eligibility criteria are met. Patients receive obinutuzumab IV over 4 hours on days 1, 2, 8, and 15 of cycle 1 and on day 1 of cycles 2-6. Patients also receive venetoclax PO QD on days 22-28 of cycle 1 and on days 1-28 of cycles 2-12. Treatment repeats every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo CT, collection of blood samples, and bone marrow aspiration and biopsy throughout the trial. After completion of study treatment, patients are followed up for 10 years after registration.
