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.

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

16 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
Time Frame
Efficacy : Mean of percent change from baseline in fasting serum TG (mg/dL) at the time of final evaluation* and immediately before it * : Week 52 or at discontinuation
Time Frame: Final evaluation (Week 52 or at discontinuation) and immediately before it
Final evaluation (Week 52 or at discontinuation) and immediately before it

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
Time Frame
Efficacy : Mean of percent change from baseline in fasting serum Total Cholesterol (mg/dL) at the time of final evaluation* and immediately before it * : Week 52 or at discontinuation
Time Frame: Final evaluation (Week 52 or at discontinuation) and immediately before it
Final evaluation (Week 52 or at discontinuation) and immediately before it
Efficacy : Mean of percent change from baseline in fasting serum LDL-C (mg/dL) at the time of final evaluation* and immediately before it * : Week 52 or at discontinuation
Time Frame: Final evaluation (Week 52 or at discontinuation) and immediately before it
Final evaluation (Week 52 or at discontinuation) and immediately before it
Efficacy : Mean of percent change from baseline in fasting serum HDL-C (mg/dL) at the time of final evaluation* and immediately before it * : Week 52 or at discontinuation
Time Frame: Final evaluation (Week 52 or at discontinuation) and immediately before it
Final evaluation (Week 52 or at discontinuation) and immediately before it
Efficacy : Mean of percent change from baseline in fasting serum non-HDL-C (mg/dL) at the time of final evaluation* and immediately before it * : Week 52 or at discontinuation
Time Frame: Final evaluation (Week 52 or at discontinuation) and immediately before it
Final evaluation (Week 52 or at discontinuation) and immediately before it

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
