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
Maximum Observed Serum Concentration, Adjusted for Baseline (Cmax[adj]) of Total Thyroxine (T4)
Time Frame: Pre-dose up to 72 hours post-dose
Pre-dose up to 72 hours post-dose
Baseline-Corrected Area Under the Serum Concentration-Time Curve (AUC) from Time Zero to 72 hours Post-dose (AUC0-72,adj) of Total Thyroxine (T4)
Time Frame: Pre-dose up to 72 hours post-dose
Pre-dose up to 72 hours 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
Time Frame
Serum Concentrations of Total Thyroxine (T4) and Triiodothyronine (T3)
Time Frame: Pre-dose up to 72 hours post-dose
Pre-dose up to 72 hours 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.
