Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: A
FCR+ABT-263
Drug: ABT-263
ABT-263 is taken orally once daily for 3 days out of each 28 day cycle. This is a dose escalation study, therefore the dose of ABT-263 will change throughout the study.
Drug: FCR
Rituximab will be given by intravenous infusion for 1 day out of each 28 day cycle; Fludarabine will be given by intravenous infusion for 3 days out of each 28 day cycle; and Cyclophosphamide will be given by intravenous infusion for 3 days out of each 28 day cycle
Other Names:
  • fludarabine, cyclophosphamide, rituximab
Active Comparator: B
BR+ABT-263
Drug: ABT-263
ABT-263 is taken orally once daily for 3 days out of each 28 day cycle. This is a dose escalation study, therefore the dose of ABT-263 will change throughout the study.
Drug: BR
Rituximab will be given by intravenous infusion for 2 days out of each 28 day cycle and Bendamustine will be given by intravenous infusion for 2 days out of each 28 day cycle

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
Time Frame
Assess the safety profile, characterize pharmacokinetics, and determine the MTD and recommended Phase 2 dose (RPTD) of ABT-263 when administered in combination with either FCR or BR in subjects with relapsed or refractory CLL.
Time Frame: Safety assessments = 1 wk, Pharmacokinetic (PK) Sampling = 1 wk for 1st 2 cycles, then, every other cycle starting Cycle 3 to Cycle 9, Determination of MTD & RPTD = Every 60 days
Safety assessments = 1 wk, Pharmacokinetic (PK) Sampling = 1 wk for 1st 2 cycles, then, every other cycle starting Cycle 3 to Cycle 9, Determination of MTD & RPTD = Every 60 days

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
Evaluate preliminary data regarding progression-free survival (PFS), tumor response rate and overall survival (OS) when ABT-263 is administered in combination with either FCR or BR.
Time Frame: Every 2 months
Tumor assessments
Every 2 months
