Number of Participants With Low and High Vital Signs Values

Vital signs were assessed after participants had rested in a supine position for no less than 5 minutes. Vital signs included systolic blood pressure, diastolic blood pressure, pulse rate, and oral body temperature. The normal ranges of vital signs were: systolic blood pressure as 90-140 millimeter of Hg (mm Hg), diastolic blood pressure as 50-90 mm Hg, pulse rate as 45-100 beats per minute, and oral body temperature as 36.3-37.5 degree Celsius. Data was reported as the number of participants who had low level values (values less than the normal range) and high level values (values more than the normal range).

Time frame: Days -28 to -2, Day -1, Days 1 to 5, and Day 10 for blood pressure and pulse rate; and Days -28 to -2, Day -1, and Day 10 for oral body temperature

Population: The safety analysis consisted of all participants who had received the single dose of the study drug (aleglitazar), whether prematurely withdrawn from the study or not.

Number of Participants With Marked Abnormalities in Clinical Laboratory Parameters

Laboratory parameters included hematology, coagulation, biochemistry, and urinalysis. A marked abnormality was defined as a test result which was outside of the marked abnormality range. Data was reported as the number of participants who had low level values (values less than the normal range) and high level values (values more than the normal range).

Time frame: Up to 6 weeks

Population: The safety analysis consisted of all participants who had received the single dose of the study drug (aleglitazar), whether prematurely withdrawn from the study or not.

Renal Clearance (CLR) of Aleglitazar, M1, and M6

CLR was calculated as Ae0-48/AUC0-48, where Ae0-48 as amount excreted in urine from time 0 to 48 hours post-dose and AUC0-48 represents area under the concentration-time curve of the analyte in plasma over the time interval from zero to the 48 hours post-dose.

Time frame: Pre-dose, 0.25, 0.5, 1, 2, 3, 4, 5, 6, 9, 12, 15, 24, 36, 48, 72, and 96 hours post-dose for plasma; 0-4, 4-8, 8-12, 12-24, and 24-48 hours post-dose for urine

Population: The PK analysis population consisted of all participants who received the study drug and adhered to the protocol. Only participants with data available for specific metabolite were analyzed.
