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 an open-label, Phase 2 study designed to assess the efficacy and safety of ibrutinib combined with rituximab in previously untreated subjects with FL.

There are two study treatment arms.

Subjects enrolled into main study treatment arm will receive ibrutinib continuously until disease progression or unacceptable toxicity. In addition, subjects will receive rituximab once weekly for four doses for the first four weeks of study treatment.

Subjects enrolled into the exploratory study treatment arm will receive ibrutinib continuously as a single agent for the first eight weeks, then ibrutinib concurrently with rituximab once weekly for four doses. After the rituximab treatment, subjects will receive ibrutinib continuously until disease progression or unacceptable toxicity.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Ages Eligible for Study

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
Overall Response Rate (ORR): Proportion of Subjects Achieving the Best Overall Responses of Complete Response (CR) or Partial Response (PR)
Time Frame: Subjects in Arm 1 will have imaging assessments every 12 weeks for the first 8 assessments, then every 24 weeks. Subjects in Arm 2 will have imaging assessments starting at week 9, then every 12 weeks for 8 assessments, then every 24 weeks.
Number of subjects achieving the best overall responses of CR or PR prior to the initiation of the next line of antineoplastic therapy as assessed by investigator per the Cheson et al, 2007 criteria. Target lesions are measured by CT, unless MRI is used as the assessment modality for lesions in anatomical locations not amenable to CT. CR is defined as the disappearance of all evidence of disease. PR is defined as >=50% decrease in the sum of the product of the diameters of up to 6 largest dominant masses.
Subjects in Arm 1 will have imaging assessments every 12 weeks for the first 8 assessments, then every 24 weeks. Subjects in Arm 2 will have imaging assessments starting at week 9, then every 12 weeks for 8 assessments, then every 24 weeks.

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.
Outcome Measure
Measure Description
Time Frame
Duration of Response (DOR)
Time Frame: Up to 45 months
DOR is defined as the interval between the date of the first documented response (CR, PR) and the date of the first documented evidence of progressive disease (PD) or death. DOR will be analyzed for the subjects who achieve an overall response during the duration of study.
Up to 45 months
Progression Free Survival (PFS)
Time Frame: Up to 45 months
PFS is defined as the time interval between the date of the first dose and the date of the earliest occurrence of PD or death due to any cause, whichever occurs first. PD is characterized by any new lesion or increase by >=50% of previously involved sites from nadir.
Up to 45 months
Overall Survival (OS)
Time Frame: Up to 45 months
Subjects will be followed for survival information up to three years after the last dose of study treatment, until new treatment or death, whichever occurs first. OS is defined as the duration of time from the date of the first dose to the date of death from any cause.
Up to 45 months
Number of Participants With Treatment-emergent Adverse Events
Time Frame: Up to 45 months
Frequency, severity, and relatedness of treatment-emergent adverse events (AEs) Frequency of treatment-emergent AEs requiring discontinuation of study drug or dose reductions
Up to 45 months
