Brief Summary:
The purpose of this study is to examine the safety and efficacy of Ibrutinib administered in combination with bendamustine and rituximab in patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma | Drug: Ibrutinib Drug: Bendamustine hydrochloride Drug: Rituximab Drug: Placebo | Phase 3 |
This is a randomized (patients will be assigned by chance to study treatments), double-blind (patients and study personnel will not know the identity of study treatments), placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial)-controlled study to determine the benefits and risks of combining ibrutinib with bendamustine and rituximab (BR) in patients with relapsed or refractory CLL/SLL following at least 1 line of prior systemic therapy. Approximately 580 patients will be randomized in a 1:1 ratio to either treatment arm A (placebo) or treatment arm B (ibrutinib 420 mg).
Study medication will be administered orally once daily on a continuous schedule. All patients will receive BR as the background therapy plus either ibrutinib or placebo for a maximum of 6 cycles, after which treatment with ibrutinib or placebo will continue until disease progression or unacceptable toxicity.
A treatment cycle will be defined as 28 days. The study will include a screening phase, a treatment phase, and a follow-up phase. Study end is defined as when either 80% of the patients have died or 5 years after the last patient is randomized into the study, whichever occurs first.
Patients in treatment arm A (placebo) who complete the treatment phase, with disease progression or (after interim analysis) meet International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria for treatment, may crossover to ibrutinib treatment (as in treatment arm B), at the investigators discretion. This open-label, next-line treatment with ibrutinib will continue until disease progression, unacceptable toxicity, withdrawal from study, or until the study end, whichever occurs earlier. One interim analysis is planned for the study. Efficacy evaluations will include computed tomography scans, laboratory testing, focused physical examinations, bone marrow biopsy and aspirate, and assessment of patient-reported outcomes. In both treatment arms, samples for the development of a population-based pharmacokinetic (PK; study of what the body does to a drug) approach will be collected. Safety will be assessed throughout the study.

Primary Outcome Measures :
- Progression-free Survival (PFS) [ Time Frame: Up to 5 years ]PFS was defined as the interval between the date of randomization and the date of disease progression or death, whichever was first reported. IWCLL 2008 criteria for PD: New enlarged nodes >1.5 cm, new hepatomegaly or splenomegaly, or other new organ infiltrates, bone lesion, ascites, or pleural effusion confirmed due to chronic lymphocytic leukemia (CLL); >=50% increase in existing lymph nodes; >=50% increase in enlargement of liver or spleen; >=50% increase from baseline in lymphocyte count (and to >=5*10^9/L) or >=50% increase from nadir count confirmed on >=2 serial assessments if absolute lymphocyte count (ALC) >=30,000 per microliter and lymphocyte doubling time is rapid, unless considered treatment-related lymphocytosis; new cytopenia (Hemoglobin b [Hgb] or platelets) attributable to CLL; and transformation to a more aggressive histology.
Secondary Outcome Measures :
- Overall Response Rate (ORR) [ Time Frame: Up to 5 years ]ORR defined as number of participants achieving a complete response (CR), complete response with incomplete marrow recovery (CRi), nodular partial response (nPR) or partial response (PR). IWCLL 2008 criteria: CR- No lymphadenopathy and hepatosplenomegaly, no constitutional symptoms, neutrophils >1.5*10^9/liter (L), platelets >100*10^9/L, Hgb >11 gram per deciliter (g/dL) and absolute lymphocyte count <4000/microliter (mcL); CRi- CR with incomplete recovery of bone marrow; nPR- participants meet criteria for CR, but the bone marrow biopsy shows B-lymphoid nodules, may represent a clonal infiltrate; PR-2 of the following when abnormal at baseline: >=50% decrease in ALC, >=50% decrease in sum products of up to 6 lymph nodes, >=50% decrease in enlargement of spleen or liver; and 1 of the following: neutrophils >1.5*10^9/L, Platelets >100*10^9/L and Hgb>11 g/dL or >=50% improvement over baseline in any of these; no new enlarged nodes or new hepatosplenomegaly.
- Overall Survival (OS) [ Time Frame: Up to 5 years ]OS was defined as the interval between the date of randomization and the date of death from any cause.
- Percentage of Participants With Minimal Residual Disease (MRD)-Negative Response [ Time Frame: Up to 5 years ]MRD-negative response was defined as the percentage of participants who reach MRD negative disease status (less than 1 chronic lymphocytic leukemia [CLL] cell per 10,000 leukocytes) in either bone marrow or peripheral blood. All randomized participants were included in this analysis. Participants with missing MRD data were considered non-responders.
- Percentage of Participants With Sustained Hematologic Improvement [ Time Frame: Up to 5 years ]Sustained hematologic improvement was defined as hematological improvement that was sustained continuously for greater than or equal to (>=) 56 days without blood transfusion or growth factors: 1) Platelet counts greater than (>)100* 109/liter (L) if baseline less than or equal to (<=) 100*109/L or increase >= 50 percent (%) over baseline; 2) Hemoglobin >11 gram per deciliters (g/dL) if baseline <= 11 g/dL or increase >= 2 g/dL over baseline.
- Median Time to Clinically Meaningful Improvement in FACIT-Fatigue Scale [ Time Frame: Up to 2 years ]Time to improvement is defined as the time interval (months) from randomization to the first observation of improvement. FACIT-Fatigue is an instrument for use as a measure of the effect of fatigue in patients with cancer and other chronic diseases. Responses to the 13-item FACIT Fatigue Scale are reported on a 5-point categorical response scale ranging from 0 (not at all) to 4 (very much). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worst score) to 52 (best score).
- Number of Participants With Clinically Relevant Shifts in Disease-Related Symptoms [ Time Frame: From the date of randomization to disease progression (Up to 2 years) ]The disease-related symptoms included fatigue, weight loss, fevers, night sweats, abdominal discomfort/splenomegaly and anorexia.
- Number of Participants Who Received Subsequent Antineoplastic Therapy [ Time Frame: Up to 5 years ]Number of participants who received subsequent antineoplastic therapy was reported.
- Change From Baseline in Beta2 Microglobulin at End of Treatment (EOT) [ Time Frame: Baseline to EOT (Up to 2 years) ]Change from baseline in beta2 microglobulin at end of treatment at time of primary analysis was reported.
- Change From Baseline in FACIT-Fatigue Scale at End of Treatment [ Time Frame: Baseline to EOT (up to 2 years) ]FACIT-Fatigue is an instrument for use as a measure of the effect of fatigue in patients with cancer and other chronic diseases. Responses to the 13-item FACIT Fatigue Scale are reported on a 5-point categorical response scale ranging from 0 (not at all) to 4 (very much). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worst score) to 52 (best score).
- Change From Baseline in EORTC QLQ-C30 Physical Functioning Score at End of Treatment [ Time Frame: Baseline to EOT (up to 2 years) ]EORTC QLQ-C30 Physical Functioning Score is a questionnaire to assess quality of life of cancer patients. It is composed of 30 items, multi-item measure (28 items) and 2 single-item measures. For the multiple item measure, 4-point scale is used and the score for each item range from "1 = not at all" to "4 = very much". Higher scores indicate worsening. The 2 single-item measure involves question about the overall health and overall quality of life which was rated on a 7-point scale ranging from "1 = very poor" to "7 = excellent". Lower scores indicate worsening. All scale and item scores were linearly transformed to be in range from 0-100. A higher score represents a higher (better) level of functioning, or a higher (worse) level of symptoms.
- Change From Baseline in EORTC QLQ-CLL 16 Domain Scores at End of Treatment [ Time Frame: Baseline to EOT (up to 2 years) ]The EORTC QLQ-CLL 16 is a 16-item disease specific module that comprises 5 domains of patient-reported health status important in CLL. There are three multi-item scales that include fatigue (2 items), treatment side effects and disease symptoms (8 items), and infection (4 items), and 2 single-item scales on social activities and future health worries. Responses are measured on a 4 point scale ranging from 1 (not at all) to 4 (very much).
- Change From Baseline in EuroQol-5 Dimension-5 Level (EQ-5D-5L) Visual Analog Scale at End of Treatment [ Time Frame: Baseline to EOT (up to 2 years) ]The EQ-5D questionnaire is a brief, generic health-related quality of life assessment (HRQOL) that can also be used to incorporate participant preferences into health economic evaluations. The EQ-5D questionnaire assesses HRQOL in terms of degree of limitation on 5 health dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) and as overall health using a visual analog scale with response options ranging from 0 (worst imaginable health) to 100 (best imaginable health).
- Change From Baseline in EuroQol-5 Dimension-5 Level (EQ-5D-5L) Utility Score Scale at End of Treatment [ Time Frame: Baseline to EOT (up to 2 years) ]The EuroQol-5 is a five dimensional health state classification. Each dimension is assessed on a 3-point ordinal scale (1=no problems, 2=some problems, 3=extreme problems). The responses to the five EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 to 1. High score indicating a high level of utility.
