Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area under the plasma concentration-time curve (AUC(0-144h)) of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. AUC(0-144) will be calculated according to the linear trapezoidal rule using the measured concentration-time values above the limit of quantification.	7 Days	No
Primary	Area under the plasma concentration-time curve (AUC(0-infinity)) of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. AUC(0-infinity) will be calculated by combining AUC(0-144) and AUC(extra). AUC(extra) represents an extrapolated value obtained by Ct/?z, where Ct is the last plasma concentration measured above the limit of quantification and ?z represents the terminal elimination rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal elimination phase.	7 Days	No
Primary	Maximum plasma concentration (Cmax) of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. Cmax will be calculated on the basis of the blood sampling time points.	7 Days	No
Primary	Plasma half life (t1/2) of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. t1/2 will be calculated on the basis of the blood sampling time points.	7 Days	No
Primary	Time to maximum plasma concentration (tmax) after oral administration of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. tmax will be calculated on the basis of the blood sampling time points.	7 Days	No
Primary	Total body clearance (CL) after intravenous administration of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. CL Total body clearance will be calculated as follows: CL = Dose / AUC(0-infinity).	7 Days	No
Primary	Volume of distribution (Vss) after intravenous administration of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. Vss will be estimated by CL [(AUMC/AUC) - (infusion time/2)], where AUMC is the area under the first moment curve.	7 Days	No
Primary	Absolute bioavailability (F) of after oral administration of ponesimod	Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ponesimod, and at various time points up to 7 days after dosing. F will be calculated using the geometric means (as derived by the mixed effect model) of AUC(0-infinity).	7 Days	No
Secondary	Change from baseline up to Day 7 in systolic blood pressure	Blood pressure (systolic and diastolic) and pulse rate will be measured using an automatic oscillometric device, always on the leading arm (i.e., leading arm = writing arm). Measurements will be recorded in the supine position after the subject has rested for a 5-minute period.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in diastolic blood pressure	Blood pressure (systolic and diastolic) and pulse rate will be measured using an automatic oscillometric device, always on the leading arm (i.e., leading arm = writing arm). Measurements will be recorded in the supine position after the subject has rested for a 5-minute period.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in pulse rate	Blood pressure (systolic and diastolic) and pulse rate will be measured using an automatic oscillometric device, always on the leading arm (i.e., leading arm = writing arm). Measurements will be recorded in the supine position after the subject has rested for a 5-minute period.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in heart rate	Heart rate will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in PR interval (time interval from the beginning of the P wave to the beginning of the QRS complex)	PR interval will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in QRS duration (time interval from the beginning of the Q wave to the end of the S wave)	QRS duration will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in QT interval (time interval from beginning of the Q wave until end of the T wave)	QT interval will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.	7 Days	Yes
Secondary	Change from baseline up to Day 7 in QT interval according to Bazett's correction (QTcB)	QTcB interval will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting. The QTcB interval is the QT interval (interval from beginning of the Q wave until end of the T wave) corrected for heart rate with Bazett's formula (QTcB = QT/RR^0.5 where RR is 60/heart rate)	7 Days	Yes

Secondary	Frequency of treatment-emergent ECG abnormalities from up to Day 7	Treatment-emergent abnormalities will be determined from standard 12-lead ECGs recorded in the supine position, after a 5-minute period of resting. Treatment-emergent ECG abnormalities are any ECG abnormalities that occur up to 144 hours after each study drug administration.	7 Days	Yes
