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

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/nurse is available and is living in the same household, or interacts with the patient to assure the correct preparation and administration of the study drug to the patient. 9. Patients living at home or old people's home. 10. General health status acceptable for a participation in a 6 months clinical trial. 11. Ability to swallow 100 -150 ml of water suspension. 12. No daily-regular/chronic intake of medications acting on central nervous system, immunosuppressants, steroids or non-steroid anti-inflammatory agents except the following allowed treatments: * SSRIs as antidepressants if they are administered at a stable and well tolerated dose for two months prior to baseline evaluation * the following drugs at a stable and well tolerated dose to symptomatic treatment of mild behavioral disorder, sleep onset-insomnia or mild depressive mood: * Risperidon max 1mg/day * Quetiapin max 25mg/day * Zolpidem max 10mg in the evening * Lorazepam max 1mg/day * Triazolam max 0,25mg/day * Alprazolam max 1mg/day * Mirtazapin max 30mg/day * Hydromorphon max 4mg/day * Levodopa max 50mg t.i.d as treatment of an age-associated extrapyramidal syndrome or restless-legs-syndrome * Acetylsalicylic acid max 100mg/day as antiplatelet agent. * Non-steroid anti-rheumatics as concomitant medication taken per request 13. No history of treatment with Warfarin, Digitoxin or Coumarin (including its derivatives) within 1 month prior to baseline. Chronic treatment with heparin s.c. as anticoagulant or digoxin for the treatment of heart disease are allowed. 14. 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 1 month prior to baseline. 15. Stable pharmacological treatment of any other chronic condition for at least one month prior to screening. 16. Treatment with a stable and well tolerated dose of one of the approved Acetylcholinesterase-Inhibitors (Donepezil, Galantamine or Rivastigmine) for at least 2 months prior to baseline evaluations. Dosage of Acetylcholine-esterase inhibitors should not be increased during the ongoing study. 17. No history of treatment with Memantine within 3 months prior to baseline evaluation. Patients with a stable and well tolerated dose of Memantine are not allowed to be included in the study. 18.
