Eligibility
Inclusion criteria
Inclusion criteria: 1. Men and women (non-childbearing potential) with a diagnosis of probable Alzheimer’s disease according to the NINCDS-ADRDA clinical criteria. 2. Age 60 - 85 years (patients over 85 years could be included after a previous assessment by the investigator and in agreement with the sponsor) 3. MRI or CT-scan assessment within 12 months before baseline corroborating the clinical diagnosis (diffuse brain atrophy predominating in medial temporal regions) and excluding other potential causes of dementia, especially cerebrovascular lesions (see exclusion criteria, number 3). 4. Mild to moderate stage of Alzheimer’s disease according to MMSE 16-26. 5. Modified Hachinski ischemic score equal to or below 4. 6. Geriatric Depression Scale below or equal 7. 7. Female patients must be either surgically sterilized or at least 1 year postmenopausal (confirmed by FSH >20, for women not surgically sterilized). 8. A caregiver/study nurse is available and is living in the same household, or interacts with the patient for >4 hours at least 4 times a week. 9. Patients living at home or old people’s home. 10. General health status acceptable for a participation in a 4 months clinical trial. 11. Ability to swallow 100 ml of water suspension. 12. SSRIs as antidepressants are permitted after maintenance of dose for two months prior to baseline evaluation. 13. No regular treatment with benzodiazepines. Lorazepam 1 mg or medication containing opioids for anxiety, sleep induction or pain will be allowed only as occasional treatment, but not within two days before cognitive assessments. 14. No history of treatment with Warfarin or Digoxin will be allowed within 3 months before screening. 15. Other drugs metabolized by the CYP3A4 with wide therapeutic window are permitted if their dose and regimen are stable and well tolerated for at least 3 months prior to screening. 16. Stable pharmacological treatment of any other chronic condition for at least one month prior to screening. 17. No regular/chronic intake of medications acting on central nervous system or any non-steroid anti-inflammatory agents. 18. Treatment with a stable and well tolerated dose of one of the approved Acetylcholinesterase-Inhibitors (e.g. Donepezil) for at least 2 months prior to baseline evaluations. Dosage of Acetylcholine-esterase inhibitors should not be increased during the ongoing study. 19. No history of treatment with Memantine within 3 months prior to baseline evaluation. 20. Signed informed consent by patient (and legal representative if applicable) 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 within 1 month prior to screening period. 3. Clinical, laboratory or neuroimaging findings consistent with: • other primary degenerative dementia, (dementia with Lewy bodies, frontotemporal dementia, Huntington’s disease, Jacob-Creutzfeld Disease, Down’s syndrome, etc) • other neurodegenerative condition (Parkinson’s disease, amyotrophic lateral sclerosis, etc.) • cerebrovascular disease (major infarct, one strategic or multiple lacunar infarcts, extensive white matter lesions) • other central nervous system diseases (severe head trauma, tumors, subdural haematoma or other space occupying processes, etc.) • seizure disorder • other infectious, metabolic or systemic diseases affecting central nervous system (syphilis, present hypothyroidism, present vitamin B12 or folate deficiency, serum electrolytes out of normal range, juvenile onset diabetes mellitus, etc.) 4. A current DSM-IV diagnosis of active major depression, schizophrenia or bipolar disorder. 5. Clinically significant, advanced or unstable disease that may interfere with evaluations, may bias the assessment of the clinical or mental status of the patient or put the patient at special risk, such as: • chronic liver disease, liver function test abnormalities or other signs of hepatic insufficiency • respiratory insufficiency • renal insufficiency (serum creatinine >2mg/dl) • heart disease (myocardial infarction, unstable angina, heart failure, cardiomyopathy within 6 months before screening) • bradycardia (heart beat 95/min.) • hypertension or hypotension requiring treatment with more than 2 drugs • AV block (type II / Mobitz II and type III), congenital long QT syndrome, sinus node dysfunction or prolonged QTcB-interval (males >450 and females >470 msec) • uncontrolled diabetes • malignant tumors within the last 5 years except skin malignancies (other than melanoma) or indolent prostate cancer • metastases 6. Disability that may prevent the subject from completing all study requirements (e.g., blindness, deafness, severe language difficulty, etc.) 7. Women who are fertile and of child bearing potential. 8. Anticoagulant treatment with heparin i.v. 9. Chronic drug intake of: • drugs metabolized by the CYP3A4 with narrow therapeutic window (i.e. warfarin, digoxin, …). • antidepressants (other than SSRIs), benzodiazepines, neuroleptics or major sedatives • antiepileptics • anticholinergics • nootropics • centrally active anti-hypertensive drugs (clonidine, ?-methyl dopa, guanidine, guanfacine, …) • opioid containing analgesics • non steroid anti-inflammatory agents (regular intake!), cortico-steroids or immunosuppressants • lithium or other inhibitor of GSK3 enzyme 10. Suspected or known drug or alcohol abuse. 11. Suspected or known allergy to any components of the study treatments. 12. Enrollment in another investigational study or intake of investigational drug within the previous 3 months. 13. Any condition which in the opinion of the investigator makes the patient unsuitable for inclusion.
