Treatment B: a single oral dose of ponesimod (10 mg) administered as 1 tablet in the fasted state in the morning. There will be a washout period between doses of 12-15 days. Treatment B/Treatment A Ponesimod 10 mg tablet Subjects will receive Treatment B followed by Treatment A. Treatment A: a single i.v. dose of ponesimod administered in the fasted state in the morning.

- Primary Outcome Measures
Name Time Method Area under the plasma concentration-time curve (AUC(0-infinity)) of ponesimod 7 Days 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/λz, where Ct is the last plasma concentration measured above the limit of quantification and λz represents the terminal elimination rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal elimination phase.
Volume of distribution (Vss) after intravenous administration of ponesimod 7 Days 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.
Area under the plasma concentration-time curve (AUC(0-144h)) of ponesimod 7 Days 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.
Maximum plasma concentration (Cmax) of ponesimod 7 Days 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.
Time to maximum plasma concentration (tmax) after oral administration of ponesimod 7 Days 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.
Total body clearance (CL) after intravenous administration of ponesimod 7 Days 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).
Plasma half life (t1/2) of ponesimod 7 Days 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.
Absolute bioavailability (F) of after oral administration of ponesimod 7 Days 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).
- Secondary Outcome Measures
Name Time Method Change from baseline up to Day 7 in heart rate 7 Days Heart rate will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.
Frequency of treatment-emergent ECG abnormalities from up to Day 7 7 Days 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.
Change from baseline up to Day 7 in diastolic blood pressure 7 Days 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.
Change from baseline up to Day 7 in pulse rate 7 Days 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.
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) 7 Days PR interval will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.
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) 7 Days QRS duration will be determined from standard 12-lead electrocardiographs (ECGs) recorded in the supine position, after a 5-minute period of resting.
Change from baseline up to Day 7 in QT interval (time interval from beginning of the Q wave until end of the T wave) 7 Days QT 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)
Change from baseline up to Day 7 in systolic blood pressure 7 Days 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).
