Age of 40 to 85 years (patients over 85 years could be included after a previous assessment by the Investigator and approved by the sponsor). 3. Brain MRI study within 24 months before the Baseline visit excluding other potential causes of parkinsonism, especially cerebrovascular lesions and space occupying lesions. 4. Mild to moderate stage of disease severity according to a score of 1 to 4 in the Golbe Staging System (Appendix 2). 5. Female patients must be without childbearing potential: either surgically sterilized or at least 1 year postmenopausal (confirmed by follicle-stimulating hormone [FSH] >20 international units [IUs]). Male patients must be willing to use barrier contraception (condom) during the study and for 6 months after the last treatment administration. 6. A caregiver (or dedicated nurse) living in the same household or interacting with the patient for >4 hours every day able to assure the correct preparation and administration of the study drug. 7. Patients living at home or in a retirement home not requiring continuous nursing care. 8. General health status acceptable for a participation in a 64-week clinical trial. 9. Ability to swallow 100 mL of water suspension. 10. Any concomitant medication for PSP must be well-tolerated and unchanged for at least 4 weeks prior to the Baseline visit and its dose and regimen should be maintained during the study if there are no clinical reasons to modify it. 11. Occupational, physical, respiratory, or speech therapy is allowed but it must be stable for at least 4 weeks prior to baseline. 12. Pharmacological treatment of any other chronic condition must be stable and well-tolerated for at least 4 weeks prior to baseline. Analgesics, occasional per request nonsteroidal anti-inflammatory agents, and treatments for transient or emergent conditions are allowed. 13. Signed informed consent (IC) by the patient (or his/her legal representative, this is applicable in Spain) prior to the initiation of any study-specific procedure. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: 1. Failure to perform screening or baseline examinations. 2. Hospitalization or change of chronic concomitant medication 1 month prior to or during the screening period (apart from pre-planned hospitalization for a condition, which did not deteriorate since 1 month prior to the screening period). 3. Clinical, laboratory or neuroimaging findings consistent with: • other primary degenerative diseases such as Parkinson’s disease; dementia with Lewy bodies; corticobasal degeneration; frontotemporal dementia; multiple system atrophy; parkinsonism-dementia complex of Guam, Kii or Guadalupe; Alzheimer’s disease; amyotrophic lateral sclerosis; Creutzfeld-Jakob Disease; Huntington’s disease; Down’s syndrome; etc. • cerebrovascular disease as major, strategic or multilacunar infarcts, or extensive white matter lesions scoring 3 in the Wahlund’s scale [Wahlund et al., 2001]. • other central nervous system diseases (hydrocephalus, severe head trauma, tumours, subdural haematoma or other relevant space occupying processes, etc.). • epilepsy. • other infectious, metabolic or systemic diseases affecting the central nervous system (syphilis, present clinically active hypothyroidism, clinically significant vitamin B12 or folate deficiency, clinically significant serum electrolyte disturbances, juvenile onset diabetes mellitus, etc.). 4. A current Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) diagnosis of active major depression, schizophrenia or bipolar disorder. 5. Clinically significant, advanced or unstable disease that may interfere with primary or secondary variable evaluations, may bias the clinical or mental assessment or put the patient at special risk, such as: • chronic liver disease, as indicated by liver function test abnormalities (ALAT, ASAT, bilirubin or GGT out of range) positive serology for Hepatitis C, or other clinical manifestations of liver disease • respiratory insufficiency • renal insufficiency (serum creatinine >2 mg/dL (>150 µmol/L) and creatinine clearance 95/min) • episodes of unstable or uncontrolled hypertension (systolic pressure >160 mm Hg or diastolic pressure >100 mm Hg) or hypotension (systolic pressure 450 msec and females >470 msec using Fridericia’s formula: QTc = QT/cube root of RR). • uncontrolled diabetes mellitus. • malignant tumors within the last 5 years except skin malignancies (other than melanoma) or indolent prostate cancer. • metastases. 6. Disability that may prevent the patient from completing all study requirements (e.g. blindness, deafness, and severe language difficulty). 7. Chronic daily drug intake of: • drugs metabolized by the cytochrome
