Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Venetoclax

Arm Description

Venetoclax will be administered orally once daily (QD) beginning with a dose-titration phase. The initial venetoclax dose is 20 mg QD. After 1 week of treatment at 20 mg QD, the dose will be escalated to 50 mg QD followed by subsequent increases, each after 1 week, to 100 mg QD, 200 mg QD and the maximum dose of 400 mg QD. Participants may continue to receive venetoclax for up to 2 years provided they continue to tolerate the drug, have no evidence of disease progression (based on investigator's assessment), do not have unacceptable toxicity, and do not meet any of the criteria for discontinuation. In countries where venetoclax is not commercially available, participants who continue to derive benefit after 2 years of treatment may be able to extend their treatment for up to 2 additional years, plus one additional year until the venetoclax extension study was open, determined on a case by case basis.

Outcomes

Primary Outcome Measures

Complete Remission Rate in Participants Not Previously Treated With BCRi Therapy - Primary Analysis
Complete remission rate is defined as the percentage of participants achieving a best response of complete remission (CR) or complete remission with incomplete marrow recovery (CRi) assessed by the investigator based on 2008 Modified International Workshop for Chronic Lymphocytic Leukemia National Cancer Institute-Working Group (IWCLL NCI-WG) criteria. CR required all of the following: Peripheral blood lymphocytes < 4000/μL Absence of lymphadenopathy by physical examination and computed tomography scan No hepatomegaly or splenomegaly by physical examination Absence of disease or constitutional symptoms (unexplained fevers > 38°C, drenching night sweats, > 10% weight loss in last 6 months) Blood counts above the following: Neutrophils > 1500/μL Platelets > 100,000/μL Hemoglobin > 110 g/L Bone marrow at least normocellular for age, < 30% lymphocytes. CRi was defined as for CR but with persistent cytopenia apparently unrelated to CLL but related to drug toxicity.

Secondary Outcome Measures

Complete Remission Rate in Participants Previously Treated With BCRi Therapy - Primary Analysis
Complete remission rate is defined as the percentage of participants achieving a best response of complete remission (CR) or complete remission with incomplete marrow recovery (CRi) assessed by the investigator based on 2008 modified IWCLL NCI-WG criteria. CR required all of the following: Peripheral blood lymphocytes < 4000/μL Absence of lymphadenopathy by physical examination and computed tomography scan No hepatomegaly or splenomegaly by physical examination Absence of disease or constitutional symptoms (unexplained fevers > 38°C, drenching night sweats, > 10% weight loss in last 6 months) Blood counts above the following: Neutrophils > 1500/μL Platelets > 100,000/μL Hemoglobin > 110 g/L Bone marrow at least normocellular for age, < 30% lymphocytes CRi was defined as for CR but with persistent cytopenia apparently unrelated to CLL but related to drug toxicity.
Overall Response Rate (ORR) - Primary Analysis
Overall response rate was defined as the percentage of participants with an overall best response of CR, CRi, nodular partial remission (nPR), or confirmed partial remission (PR) based on the 2008 modified IWCLL NCI-WG criteria assessed by the investigator. CR and CRi are defined above. nPR is defined as for CR but bone marrow nodules could be identified histologically. For PR at least 2 of the following must be met: 50% decrease in peripheral blood lymphocyte count from the Baseline value; 50% reduction in lymphadenopathy; 50% reduction in the size of the liver and/or spleen (if abnormal prior to therapy); In addition at least 1 of the following criteria must be met: Neutrophils > 1,500/μL or ≥ 50% improvement over Baseline; Platelets > 100,000/μL or ≥ 50% improvement over Baseline; Hemoglobin > 11.0 g/dL or ≥ 50% improvement over Baseline without transfusions or exogenous growth factors. PR must have been confirmed at least 7 weeks later.
Duration of Overall Response (DOR) - Primary Analysis
Duration of response was defined as the time from the date of first response (CR, CRi, nPR, or PR) to the earliest date that progressive disease (PD) was objectively documented (radiographic or clinical) or death. Duration of response was analyzed by Kaplan-Meier (K-M) methodology. If a participant was still responding the data were censored at the date of the last available disease assessment prior to the data cutoff date.
Time to Progression (TTP) - Primary Analysis
Time to progression was defined as the time from the date of first dose of venetoclax to the date of earliest PD (radiographic or clinical). Participants who did not experience disease progression were censored at the date of the last available disease assessment prior to the data cutoff date; participants with no post-baseline disease assessments were censored at the first dose date plus 1 day. Time to progression was estimated using Kaplan-Meier methodology.
Progression-Free Survival (PFS) - Primary Analysis
Progression-free survival (PFS) was defined as the time from the date of first dose of venetoclax to the date of earliest PD (radiographic or clinical) or death. Participants who did not experience disease progression or death were censored at the date of the last available disease assessment prior to the data cutoff date; participants with no post-baseline tumor assessment or clinical assessment for progression were censored at the date of first dose plus 1 day. Progression-free survival was analyzed by Kaplan-Meier methodology.
Overall Survival (OS) - Primary Analysis
Overall survival (time to death) was defined as the time from the first dose date of venetoclax to the date of death. If a participant had not died the data were censored at the date when they were last known to be alive prior to the cutoff date. Overall survival was analyzed using Kaplan-Meier methodology.
Change From Baseline in Functional Assessment of Cancer Therapy - Leukemia Questionnaire (FACT-Leu)
The FACT-Leu is a 44-item, leukemia-specific questionnaire designed to assess health-related quality of life (HRQoL) and leukemia-specific symptoms using a core set of questions (Functional Assessment of Cancer Therapy-General; FACT-G), and a cancer site-specific leukemia subscale. Questions are scored on a scale from 0 (not at all) to 4 (very much). FACT-G consists of 27 general items divided into 4 primary HRQoL domains: Physical Well-being (PWB; 7 items; score range 0-28), Social/Family Well-being (SWB; 7 items; score range 0-28), Emotional Well-being (EWB; 6 items; score range 0-24), Functional Well-being (FWB; 7 items; score range 0-28). The leukemia subscale consists of 17 items (score range 0-68) that assess patient concerns relating to leukemia. Three summary scales were calculated: FACT-Trial Outcome Index composed of the PWB, FWB, and leukemia subscale (score range 0-124); FACT-G (score range 0-108) and the FACT-Leu Total (range 0-176). Higher scores reflect better HRQoL.
Change From Baseline in Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-Fatigue)
The FACIT-Fatigue questionnaire measures fatigue and its effect on functioning and daily activities. The FACIT-Fatigue includes 13 items answered on a 5-point rating scale based on a 7-day recall period. Scores range from 0 to 52, with lower scores reflecting greater fatigue.
Change From Baseline in EuroQoL 5 Dimension 5 Level Questionnaire (EQ-5D-5L) Health Index Score
The EQ-5D-5L is a generic measure of health status consisting of two parts: a descriptive system consisting of 5 items and a visual analog scale (VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The participant is asked to rate each dimension on 5 levels of severity (1: no problems, 2: slight problems, 3: moderate problems, 4: severe problems, 5: extreme problems). The scores for the 5 dimensions are used to compute a single health utility index score representing the general health status of the individual. The health index score ranges from zero (defined as a health state equivalent to being dead) to 1 (full health).
Change From Baseline in EuroQoL 5 Dimension 5 Level Questionnaire (EQ-5D-5L) Visual Analog Scale Score
The EQ-5D-5L is a generic measure of health status consisting of two parts, a descriptive system consisting of 5 items and a visual analog scale (VAS). The VAS assesses the participant's self-rated overall health on a scale from 0 (worst health imaginable) to 100 (best health imaginable).

5. Study Description

Brief Summary
The purpose of this study is to evaluate the efficacy of venetoclax monotherapy in participants with relapsed/refractory CLL with or without the 17p deletion or TP53 mutation, including those who have received prior treatment with a B-cell receptor inhibitor.
Detailed Description
Following the Screening period, all eligible participants initiate venetoclax on a once daily (QD) dosing schedule. To mitigate the risk for tumor lysis syndrome (TLS), dosing will start with a 5-week dose titration phase. Participants may receive venetoclax for up to 2 years provided they continue to tolerate the drug, have no evidence of disease progression (based on investigator assessment), do not have unacceptable toxicity and do not meet any of the criteria for subject discontinuation. In countries where venetoclax is not commercially available, participants who continued to derive benefit after 2 years of treatment may extend their treatment for up to 2 additional years in an extended access phase. Participants in the extended access phase of this study who continue to derive benefit from venetoclax after the 2-year extension and are transferring to the venetoclax extension study, Study M19-388 (NCT03844048), may remain in Extended Access for up to 1 additional year or until the extension study is approved and initiated at the site, whichever is sooner.

CR required all of the following: Peripheral blood lymphocytes < 4000/μL Absence of lymphadenopathy by physical examination and computed tomography scan No hepatomegaly or splenomegaly by physical examination Absence of disease or constitutional symptoms (unexplained fevers > 38°C, drenching night sweats, > 10% weight loss in last 6 months) Blood counts above the following: Neutrophils > 1500/μL Platelets > 100,000/μL Hemoglobin > 110 g/L Bone marrow at least normocellular for age, < 30% lymphocytes CRi was defined as for CR but with persistent cytopenia apparently unrelated to CLL but related to drug toxicity.
Time Frame
From first dose of study drug until the end of study; overall median time on follow-up was 49.5 months.
Title
Overall Response Rate (ORR) - Final Analysis
Description
Overall response rate was defined as the percentage of participants with an overall best response of CR, CRi, nodular partial remission (nPR), or confirmed partial remission (PR) based on the 2008 modified IWCLL NCI-WG criteria assessed by the investigator. CR and CRi are defined above. nPR is defined as for CR but bone marrow nodules could be identified histologically. For PR at least 2 of the following must be met: 50% decrease in peripheral blood lymphocyte count from the Baseline value; 50% reduction in lymphadenopathy; 50% reduction in the size of the liver and/or spleen (if abnormal prior to therapy); In addition at least 1 of the following criteria must be met: Neutrophils > 1,500/μL or ≥ 50% improvement over Baseline; Platelets > 100,000/μL or ≥ 50% improvement over Baseline; Hemoglobin > 11.0 g/dL or ≥ 50% improvement over Baseline without transfusions or exogenous growth factors. PR must have been confirmed at least 7 weeks later.
Time Frame
From first dose of study drug until the end of study; overall median time on follow-up was 49.5 months.
Title
Duration of Overall Response (DOR) - Final Analysis
Description
Duration of response was defined as the time from the date of first response (CR, CRi, nPR, or PR) to the earliest date that progressive disease (PD) was objectively documented (radiographic or clinical) or death. Duration of response was analyzed by Kaplan-Meier (K-M) methodology. If a participant was still responding the data were censored at the date of the last available disease assessment prior to the data cutoff date.
Time Frame
From first dose of study drug until the end of study; overall median time on follow-up was 49.5 months.
Title
Time to Progression (TTP) - Final Analysis
Description
Time to progression was defined as the time from the date of first dose of venetoclax to the date of earliest PD (radiographic or clinical). Participants who did not experience disease progression were censored at the date of the last available disease assessment prior to the data cutoff date; participants with no post-baseline disease assessments were censored at the first dose date plus 1 day. Time to progression was estimated using Kaplan-Meier methodology.
Time Frame
From first dose of study drug until the end of study; overall median time on follow-up was 49.5 months.
Title
Progression-Free Survival (PFS) - Final Analysis
Description
Progression-free survival (PFS) was defined as the time from the date of first dose of venetoclax to the date of earliest PD (radiographic or clinical) or death. Participants who did not experience disease progression or death were censored at the date of the last available disease assessment prior to the data cutoff date; participants with no post-baseline tumor assessment or clinical assessment for progression were censored at the date of first dose plus 1 day. Progression-free survival was analyzed by Kaplan-Meier methodology.
Time Frame
From first dose of study drug until the end of study; overall median time on follow-up was 49.5 months.
Title
Overall Survival (OS) - Final Analysis
Description
Overall survival (time to death) was defined as the time from the first dose date of venetoclax to the date of death. If a participant had not died the data were censored at the date when they were last known to be alive prior to the cutoff date. Overall survival was analyzed using Kaplan-Meier methodology.
Time Frame
From first dose of study drug until the end of study; overall median time on follow-up was 49.5 months.
Title
Minimal Residual Disease (MRD) Negativity Rate - Primary Analysis
Description
The MRD negativity rate is defined as the percentage of participants who had MRD negative status with less than one CLL cell per 10,000 leukocytes (< 10-⁴) in peripheral blood and bone marrow. MRD was evaluated using next-generation sequencing. Per protocol, peripheral blood MRD assessments were to be collected from all participants at Week 24 and Week 48 and at the time the bone marrow assessment for confirmation of CR/CRi, and bone marrow (BM) MRD assessments were to be collected for participants undergoing a bone marrow procedure for confirmation of CR/CRi. Participants with no blood or BM MRD assessments were included in the calculation of MRD negativity rate as not having MRD negative status.
Time Frame
From first dose of study drug until the last participant completed Week 48 assessments (data cut-off date 30 June 2019); overall median time on follow-up was 23.2 months.
