简要总结
This is a prospective, single-center, double-blind, randomized, placebo-controlled, ascending single oral dose and food interaction Phase 1 study. It will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of ascending single oral doses of ACT-389949 in healthy male subjects. It will also investigate the effect of food on the pharmacokinetics, safety, and tolerability of a single dose of ACT-389949.

Change from baseline up to 60 hours in pulse rate
时间窗: 60 hours
Pulse rate will be measured using an automatic oscillometric device, always on the dominant arm (i.e., dominant arm right = writing with right hand)
Change from baseline up to 60 hours in body temperature
时间窗: 60 hours
Body temperature will be measured in the sitting position using the same thermometer(s) for all the subjects and throughout the study.
Change from baseline up to 60 hours in body weight
时间窗: 60 hours
Body weight will be measured using the same weighing scale for all subjects and throughout the study. The weighing scale should have a precision of at least 0.5 kg.
Change from baseline up to 60 hours in QTcB interval
时间窗: 60 hours
A standard 12-lead electrocardiogram (ECG) is to be recorded at rest with the subject in the supine position for a 5-minute period. 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 60 hours in QTcF interval
时间窗: 60 hours
A standard 12-lead ECG is to be recorded at rest with the subject in the supine position for a 5-minute period. The QTcF interval is the QT interval (interval from beginning of the Q wave until end of the T wave) corrected for heart rate with Fridericia's formula (QTcF = QT/RR\^0.33 where RR is 60/heart rate).
Treatment-emergent ECG abnormalities from baseline up to 60 hours
时间窗: 60 hours
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 defined as ECG abnormalities occurring up to 60 h after study drug administration in each treatment period.
