An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment or events associated with liver injury and impaired liver function were categorized as SAE. All participants who take at least one dose of study treatment were included in Safety Population.

Population: Safety Population. Only those participants with data available at the specified time points were analyzed (represented by n=X in category titles).

Temperature of participants were measured at indicated time points in semi-supine position after 5 minutes rest. Day 1 (Pre-dose) value was defined as Baseline for vital sign parameters. Change from Baseline was defined as difference between post-dose visit values minus Baseline value.
