FD Cohort: Complete Response Rate (CRR; Complete Response/Complete Response With Incomplete Blood Count Recovery [CR/CRi]) Rate

CR/CRi rate is defined as the percentage of participants achieving a best overall response of complete response (CR), CR with incomplete blood count recovery (CRi) per 2008 IWCLL criteria (halleck et al.) on or prior to initiation of subsequent antineoplastic therapy or, if applicable, reintroduction of study treatment, whichever occurred earlier. (NCT02910583)
Timeframe: From the first dose of ibrutinib to the first confirmed PD up to primary analysis data cutoff date of 15 December 2020. Median follow-up time was 27.9 months at the time of the primary analysis.

FD Cohort: DOR

Duration of response was calculated for participants achieving a response (CR, CRi, nPR, PR) based on 2008 IWCLL response criteria (Halleck et al.) and defined as the interval between the date of initial documentation of a response including PR with lymphocytosis, until disease progression (PD) or death from any cause, whichever occurred first. As the median DOR was not reached as of the median 27.9 months study follow-up, the Kaplan-Meier estimate of DOR at 24 months landmark time was presented. (NCT02910583)
Timeframe: From initial documentation of a response, until PD or death from any cause, whichever occurs first. Overall median follow-up time was 27.9 months at the time of the primary analysis (data cutoff date: 15 December 2020).

FD Cohort: Kaplan-Meier Estimate of OS Rate at 24 Months Landmark Time

OS is defined as the time from the first dose date of study treatment until date of death due to any cause. As the median OS was not reached as of the median 38.2 months study follow-up, the Kaplan-Meier estimate of OS rate at 24 months landmark time was presented. (NCT02910583)
Timeframe: From the first dose of ibrutinib to time of death. Overall median follow-up time was 27.9 months at the time of the primary analysis (data cutoff date: 15 December 2020).

FD Cohort: Kaplan-Meier Estimate of PFS Rate at 24 Months Landmark Time

PFS was defined as time from the first dose date of study treatment until disease progression (PD) or death from any cause, whichever occurs first. Assessment of PD was conducted in accordance with the 2008 IWCLL criteria (Halleck et al). As the median PFS was not reached as of the median 27.9 months study follow-up, the Kaplan-Meier estimate of PFS rate at 24 months landmark time was presented. (NCT02910583)
Timeframe: From the first dose of ibrutinib to the first confirmed PD or death. Overall median follow-up time was 27.9 months at the time of the primary analysis (data cutoff date: 15 December 2020).

FD Cohort: TLS Risk Reduction Rate With 3-Cycle Ibrutinib Lead-In (Percentage of Participants No Longer High Risk After 3-cycle Lead-in)

TLS risk reduction was summarized by the percentage of participants with TLS risk reduced from high at baseline to medium or low after ibrutinib lead-in. A reduction in TLS risk from high risk to medium or low risk is clinically meaningful because there is a reduction in the extent of TLS monitoring and risk of hospitalization. TLS risk category is defined as the tumor burden category, where: Low=All lymph nodes (LN) < 5 cm AND absolute lymphocyte count (ALC) < 25 x 10^9/L; Medium=Any LN 5 cm to < 10 cm OR ALC ≥ 25 x 10^9/L; High=Any LN ≥ 10 cm OR ALC ≥ 25 x10^9/L AND any LN ≥ 5 cm. (NCT02910583)
Timeframe: Baseline, and last post-baseline value on or prior to venetoclax first dose date (cycle 4 day 1) or, for participants who never received venetoclax, the post-baseline value closest to cycle 4 day 1 (i.e. 84 days after the first dose date of ibrutinib).

MRD Cohort: 1-Year Disease-Free Survival (DFS) Rate in Confirmed uMRD Randomized Participants

DFS is defined as time from randomization date to MRD-positive relapse, or disease progression per investigator assessment (per 2008 International Workshop for Chronic Lymphocytic Leukemia [IWCLL] criteria [Halleck et al]) or death from any cause, whichever occurred first. 1-year DFS estimated using Kaplan-Meier method at 12 months landmark time.

FD Cohort: Percentage of Participants With TEAEs, Treatment-Emergent SAEs, and Discontinuations Due to TEAEs

An AE is any untoward medical occurrence, which does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires unplanned in-patient hospitalization >24 hours or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is an important medical event. Severity of events were graded according to the Common Terminology Criteria for Adverse Events version 4.03: mild=grade1, moderate=grade 2, severe=grade 3, life-threatening=grade 4, death=grade 5. Causal relation of study drug and event was assessed as not related, unlikely, possibly or probably related to the study drug. (NCT02910583)
Timeframe: From first dose until 30 days following last dose of study drug (up to data cutoff date of 15 Dec 2020). Treatment duration for the FD cohort was 13.3 months for ibrutinib and 11.1 for venetoclax.

MRD Cohort: MRD-Negativity Rate (MRR)

"MRR is defined as the percentage of participants who achieve MRD-negativity in either peripheral blood (PB) or bone marrow (BM) and achieve confirmed clinical response PR or better per 2008 IWCLL criteria (Halleck et al.). MRD-negativity is defined as <1 CLL cell per 10,000 leukocytes (<1 x 10^4), as assessed by flow cytometry of a PB or BM aspirate sample. Confirmed MRD-negative response for randomization purposes requires MRD-negativity serially over at least 3 cycles, with negativity in both BM and PB.~This rate is calculated in the uMRD Not Confirmed randomized population during the period from randomization date and before any reintroduced treatment." (NCT02910583)
Timeframe: From randomization date until before any reintroduced treatment. Overall median follow-up time was 38.2 months at the time of the primary analysis (data cutoff date: 15 December 2020).

MRD Cohort: Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs), Treatment-Emergent Serious Adverse Events (SAEs), and Discontinuations Due to TEAEs

An adverse event (AE) is any untoward medical occurrence, which does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires unplanned in-patient hospitalization >24 hours or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is an important medical event. Severity of events were graded according to the Common Terminology Criteria for Adverse Events version 4.03: mild=grade1, moderate=grade 2, severe=grade 3, life-threatening=grade 4, death=grade 5.
