Primary Outcome Measures
NameTimeMethod
To evaluate the effect of a single dose of JMKX001899 on the change in time-matched QTc intervals compared with placebo48 hours

QTc interval was measured by electrocardiograms to evaluate the potential effect of JMKX001899 plasma concentrations on the QTc interval using linear mixed-effect exposure-response modeling, including the predicted ddQTc at Cmax values corresponding to exposure levels
