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.

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
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)
Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, and 72 hours (hrs) post-dose
Area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration (AUClast).
0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, and 72 hours (hrs) post-dose
Maximum Observed Plasma Concentration (Cmax)
Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose

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
Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC [0-∞])
Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
AUC (0-∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-∞). It is obtained from AUC (0-t) plus AUC (t-∞).
0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
Extrapolated Area Under the Curve (AUC Percent [%] Extrap)
Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
AUC%extrap is the percentage of AUC [0-∞] obtained by forward extrapolation. It is calculated as (AUC [0-∞] minus AUClast)*100/ AUC [0-∞], where AUC [0-∞] = Area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time (0-∞) and AUClast is area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration.
0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
Plasma Decay Half Life (t1/2)
Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
Time to Reach Maximum Observed Plasma Concentration (Tmax)
Time Frame: 0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose
0 (pre-dose), 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48 and 72 hrs post-dose

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.
