Clinical Trial Summary

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	FACT-Leukemia total score	Will include linear regression analyses by arm.	At randomization and at months 3, 6, 9, 12, 15, 18, 24, 30, and 36
Other	The individual components of the FACT-Leukemia	Will include physical, social, emotional, and functional well-being. Will include linear regression analyses by arm.	At randomization and at months 3, 6, 9, 12, 15, 18, 24, 30, and 36
Other	Patient-reported health-related quality of life (HRQoL)	Will use simple descriptive statistics (means, medians, standard deviations, ranges) to describe patient-reported health related quality of life using the FACT-Leukemia and its individual domains between randomized arms. To assess potential trends, P-values using t-tests will be provided.	Up to 36 months
Primary	Overall survival	The final analysis will use stratified Cox proportional hazards regression stratified by Chronic Lymphocytic Leukemia [CLL] International Prognostic Indicator [CLL-IPI] Risk score status (high risk versus very high risk) with a two-sided alpha of 0.042. The final analysis will occur after 58 OS events have been observed, or at 4 years after accrual completes, whichever occurs first. Under the alternative hypothesis, the final analysis is expected to occur at approximately 7.9 years after study activation (about 3.8 years after accrual completes).	From the day of registration on study until death from any cause with observations censored on the day of last contact for participants not known to have died, assessed up to 10 years
Primary	Functional Assessment of Cancer Therapy (FACT)-Leukemia total score	A single comparison in the FACT-Leukemia total scores between patients randomized to early V-O versus delayed V-O will be conducted at the alpha=.05 level. The analysis of the 2-year FACT-Leukemia Total score will be conducted using multiple linear regression analysis, adjusting for stratification factor and the baseline FACT-Leukemia Total score as covariates. Will also conduct longitudinal modeling of the outcome measures over time.	At 2 years
Secondary	Incidence of adverse events	Will utilize the CTCAE (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events) version 5.0 for toxicity and adverse event reporting.	Up to 10 years
Secondary	Overall Response rate	Will be compared using Fisher's exact test.	Up to 10 years
Secondary	Progression free survival	Will be estimated using the Kaplan-Meier method and will be compared using log-rank tests and Cox regression models.	From the day of registration on study until the first of: relapse from complete response, progression, or death from any cause, assessed up to 10 years
Secondary	Event free survival	Will be estimated using the Kaplan-Meier method and will be compared using log-rank tests and Cox regression models.	From the day of registration on study until the first of: relapse from complete response, death from any cause, start of new (non-protocol) therapy, or completion of protocol therapy without documentation of complete response, assessed up to 10 years
Secondary	Relapse free survival	Will be estimated using the Kaplan-Meier method and will be compared using log-rank tests and Cox regression models.	From the date the participant first achieves complete response until relapse from complete response or death from any cause, assessed up to 10 years
Secondary	Time to second treatment	Will be defined as the next chronic lymphocytic leukemia (CLL) treatment the patient receives after removal from protocol therapy. Will be estimated using the Kaplan-Meier method and will be compared using log-rank tests and Cox regression models.	Up to 10 years
Secondary	Patient compliance	Will be reported descriptively by arm.	Up to 10 years
