Dose proportionality of single doses of ACT-451840
Ramy czasowe: 4 days
|
Blood samples for pharmacokinetic analysis will be taken immediately prior to dosing with ACT-451840 and at 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24, 36, 48, 72, and 96 hours after dosing. Dose proportionality will be explored by the power model as described by Gough et al [1995]. The power model will be applied to the loge AUC0-∞ and Cmax data. A point estimate and 90% Confidence Interval (CI) will be produced for the population mean slope. Approximate dose proportionality will be concluded if the 90% CI for the slope is completely contained in the range (1+log(0.5))/log(r), 1+log(2)/log(r) where r = high dose/low dose. |

Percentage of administered ACT-451840 excreted unchanged in urine
Ramy czasowe: 4 days
|
A baseline urine sample will be collected from each subject in the selected dose group after admission on Day -1.
On Day 1, subjects will be instructed to empty their bladder immediately prior to study drug intake.
Thereafter, all urine produced will be collected during the 4 days following study drug intake until the morning of Day 5. On Day 1, urine will be collected at three consecutive 8-hour intervals, from 0-8 hours, 8-16 hours, and 16-24 hours.
On Days 2, 3, and 4 urine will be collected in 24-hours intervals.

Anti-malarial half-maximal inhibitory concentration (IC50) of ACT-451840
Ramy czasowe: 4 days

Blood (2.5 mL) will be collected by direct venipuncture or via an intravenous catheter placed in an antecubital vein in the arm into 3.5 mL vacutainer serum separation tubes.
The anti-malarial IC50 of ACT-451840 will be determined using a bioassay and ACT-451840 IC50 concentrations will be estimated based on the measured antimalarial activity.
