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.

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.

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

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Time Frame: up to 30 weeks
Complete Response (CR) + Partial Response (PR) Determined on the Basis of Revised Response Criteria for Malignant Lymphoma (Revised RC 2007)
up to 30 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
Complete Response (CR) Rate
Time Frame: up to 30 weeks
Determined on the Basis of Revised Response Criteria for Malignant Lymphoma (Revised RC 2007)
up to 30 weeks
Progression Free Survival (PFS)
Time Frame: up to 30 weeks
PFS = day of the first PFS event - day of start of study treatment + 1
up to 30 weeks
Duration of Response (DOR)
Time Frame: up to 30 weeks
DOR is the period from the date of achieving CR, or PR in the responders to the earliest onset date of any progression events calculated using the Kaplan-Meier estimator. The median and the 95% Confidence Interval (CI ) were calculated using Greenwood's formula.
up to 30 weeks
Overall Survival (OS)
Time Frame: up to 30 weeks.
Death due to any given cause was defined as an event. OS was calculated using the Kaplan-Meier estimator. The median and the 95% CI were calculated using Greenwood's formula.
up to 30 weeks.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
