Outcomes
Primary Outcomes
Number of participants with Adverse Events, as a measure of safety and tolerability
Time Frame: From signing of informed consent up to 30 days after the final visit
AE reports include a description of the AE, date and time of onset and resolution, intensity, and relationship to IMP.
Changes in vital signs as a measure of safety and tolerability
Time Frame: Screening, Day-1, at select dosing days and at 5 to 7 days post dose for single dose, and 15 to 17 days post first dose in multiple dosing.
Pulse rate,body temperature,blood pressure, and orthostatic changes.
Changes in Safety Lab parameters as a measure of safety and tolerability
Time Frame: Screening, Day-1, at select dosing days, and at 5 to 7 days post dose for single doseand 15 to 17 days post first dose in multiple dosing.
Hematology, clinical chemistry, urinalysis
Changes in 12-lead electrocardiograms as a measure of safety and tolerability
Time Frame: Screening, pre-dose, at select dosing days and at 5 to 7 days post dose for single dose,and 15 to 17 days post first dose in multiple dosing.
Change in ECG parameters
Secondary Outcomes
- Pharmacokinetic measures in cerebro spinal fluid (CSF) in young males as measured by max observed CSF (Cmax CSF)(Part 1 - 1h, 2h,3h post dose)
- Pharmacokinetic measures to assess the food effect as measured by ANOVA(Pre-dose, multiple time points to 24h, and at 12h, 24h and 5 to 7 days post dose.)
- Pharmacodynamic response as measured by pupillometry(Multiple time points Day1 to 6h post dose Part 1 only.)
- Pharmacokinetic measures in urine in young males and elderly male and female subjects as measured by amount of urine excreted at collection intervals(Pre-dose,multiple 4h collection intervals to 24h post dose on select dosing days to Day 10 for multiple dosing.)
- Pharmacodynamic response as measured by Bond and Lader visual analogue scale(Day 1 at multiple timepoints to 24h post dose.)
- Pharmacodynamic response as measured by changes in qEEG and Event Related Potentials (ERP)(Screening, Day-1, Day 4, Day 9 multiple dosing regimen only)
- Pharmacokinetic measures in plasma as measured by Peak plasma concentration (Cmax)(Pre-dose, multiple time points to 24h, at select dosing days, and 5 to 7 days post dosefor single dose,and 15 to 17 days post first dose in multiple dosing.)
