Primary Outcome Measures

| Cardiovascular safety assessments after single and multiple ascending dose administration at baseline and repeatedly until study completion | This safety outcome combines the measure of a set of cardiovascular safety parameters extracted from ECGs, 25 hours-Holter ECGs and from vital signs assessments | Starting about 24 hours before dosing and continued until about 7-14 days after last dose | 
| Central nervous system safety assessments after single and multiple ascending dose administration at baseline and repeatedly until study completion | This safety outcome combines the measure of a set of central nervous system safety parameters extracted from EEGs and neurological examinations | Starting about 24 hours before dosing and continued until about 7-14 days after last dose | 
| Ocular safety assessments after single and multiple ascending dose administration at baseline and repeatedly until study completion | This safety outcome combined the measure of a set of ocular parameters including best corrected visual acuity and other parameters assessed by the mean of slit lamp biomicroscopy and dilated ophthalmoscopy examinations and by optical coherence tomography and electroretinography | Starting about 24 hours before dosing and continued until about 7-14 days after last dose | 
| General safety assessments after single and multiple ascending dose administration at baseline and repeatedly until study completion | This general safety outcome combines the measure of blood laboratory parameters and the outcome of physical examinations | Starting about 24 hours before dosing and continued until about 7-14 days after last dose |
