Outcome results
Half-life (T-1/2) of Ifetroban and Ifetroban Acylglucuronide
Plasma concentrations of ifetroban and its major active metabolite were measured at Baseline and Study Hours 1, 2, 4, 8, 12, 24, 48, 49, 50, 52, 56, 60, and 72 to determine the Pharmacokinetic parameters.
Time frame: 3 days
Population: Patients from which a full series of plasma samples were obtained from baseline through Hour 72 were included in the calculations of the PK parameters. Where the number of participants analyzed in an arm is lower than the number exposed for that arm, the patients with missing data did not contribute to the calculation of the PK parameters.

Change in 24-hour Urine Volume
The volume of urine collected in a 24-hour post-treatment period minus the volume collected in a 24-hour pre-treatment period.
Time frame: Baseline to Hour 96
Population: Data were missing for the post-treatment urine volume measurements in 9 of 42 ifetroban patients and 3 of 13 placebo patients so they were excluded from the analysis.
