A Study of PCI-32765 (Ibrutinib) Versus Rituximab in Relapsed or Refractory Chronic Leukemia/Lymphoma

June 26, 2018 updated by: Janssen Research & Development, LLC

A Randomized, Multicenter, Open-Label, Phase 3 Study of the Bruton's Tyrosine Kinase (BTK) Inhibitor PCI-32765 (Ibrutinib) Versus Rituximab in Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

The purpose of this study is to evaluate the efficacy and safety of ibrutinib versus rituximab in adult Asia Pacific region patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized (individuals assigned to study treatment by chance), open-label (identity of assigned study drug will be known) study designed to evaluate the efficacy and safety of ibrutinib versus rituximab in adult Asia Pacific region patients with relapsed/refractory CLL or SLL with active disease requiring treatment who have failed at least 1 prior line of therapy and are not considered appropriate candidates for treatment or retreatment with purine analog-based therapy. Approximately 150 patients will be randomly assigned in a 1:2 ratio into 2 treatment arms to receive either intravenous rituximab (Treatment Arm A) for 6 cycles or oral ibrutinib (Treatment Arm B) until disease progression or unacceptable toxicity, whichever occurs first. The study will include screening, treatment, and follow-up phases. Treatment will extend from randomization until study drug discontinuation. Follow-up will consist of 2 phases: post-treatment (from the discontinuation of treatment for reasons other than disease progression until the patient has progressive disease) and post-disease progression (subsequent anticancer therapy and survival status will be recorded until death, lost to follow-up, consent withdrawal, or study closure). Patients in the rituximab arm with disease progression or who meet the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria for requiring subsequent anti-CLL therapy may be considered for cross over to receive ibrutinib 420 mg orally, daily until disease progression, unacceptable toxicity, withdrawal from study, or until study end whichever occurs earliest. Efficacy evaluations will assess for disease response and progression in accordance with International Workshop on Chronic Lymphocytic Leukemia 2008 criteria. Serial pharmacokinetic (study of what a drug does to the body) blood samples will be collected in the ibrutinib treatment group. Safety will be assessed throughout the study.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression-free Survival (PFS)
Time Frame: From the date of randomization to the date of disease progression or death, whichever was first reported (Up to 3.7 years)
Progression-free survival was defined as the interval between the date of randomization and the date of disease progression or death, whichever was first reported. International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria for progressive disease (PD): New enlarged nodes greater than (>)1.5 centimeter (cm), new hepatomegaly or splenomegaly, or other organ infiltrates; greater than or equal to (>=)50 percent (%) increase from nadir in existing lymph node or >=50% increase from nadir in sum of product of diameters of multiple nodes; >=50% increase from nadir in enlargement of liver or spleen; >=50% increase from baseline in lymphocyte count (and to >=5*10^9/L) unless considered treatment-related lymphocytosis; New cytopenia (Hemoglobin b [Hgb] or platelets) attributable to chronic lymphocytic leukemia (CLL) and transformation to a more aggressive histology.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
