Trial outcomes

Primary outcomes

1

Adverse Events(AEs)

Assesment of Safety and Tolerability: Incidence and severity of treatment-emergent Adverse Events(AEs) and Serious Adverse Events(SAEs)

Time frame
Before treatment and within 57 days after treatment

Secondary outcomes

1

Plasma Pharmacokinetic (PK) Parameter: AUC0-last

Area Under the Plasma Concentration-Time Curve from Time 0 to the Last Measurable Non-zero Concentration

Time frame
Before treatment and within 48 hours after treatment
2

Plasma Pharmacokinetic (PK) Parameter: AUC0-inf

Area Under the Plasma Concentration-Time Curve from Time 0 Extrapolated to Infinity

Time frame
Before treatment and within 48 hours after treatment
3

Plasma Pharmacokinetic (PK) Parameter: Cmax

Peak Plasma Concentration

Time frame
Before treatment and within 48 hours after treatment
4

Plasma Pharmacokinetic (PK) Parameter: Tmax

Time to reach Cmax. If the maximum value occurs at more than one time point, Tmax is defined as the first time point with this value
