Primary Outcome Measures :
  1. Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment. [ Time Frame: Baseline and 12 weeks ]
    Neuropsychological Test Battery (NTB) response, defined as change from baseline in total z-score after 12 weeks of treatment. The NTB Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean at baseline. Negative numbers indicate values lower than baseline and positive numbers indicate values higher than baseline. Change from baseline will be calculated as the post-baseline composite z-score minus the pre-treatment z-score, such that a positive change indicates an improvement from baseline

  2. Change From Baseline in Neuropsychological Test Battery in Total Z-score After 12-week Treatment From Two Twin Trials, Present 1289.5 (NCT02240693) and 1289.7 (NCT02337907) [ Time Frame: Baseline and 12 weeks ]
    Neuropsychological Test Battery (NTB) response, defined as change from baseline in total z-score after 12 weeks of treatment. The NTB Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean at baseline. Negative numbers indicate values lower than baseline and positive numbers indicate values higher than baseline. Change from baseline will be calculated as the post-baseline composite z-score minus the pre-treatment z-score, such that a positive change indicates an improvement from baseline


Secondary Outcome Measures :
  1. Change From Baseline in ADCS-MCI-ADL (Alzheimer's Disease Cooperative Study/Activities of Daily Living for Patients With Mild Cognitive Impairment) Total Score After 12-week Treatment [ Time Frame: Baseline and 12 weeks ]

    Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL) is a rating scale used to assess basic and instrumental activities of daily living. In the full version of the scale, 23 items are rated by the investigator using information supplied by the caregiver.

    Each item has a score range varying from 0-3 to 0-5. The sum score can range from 0 to 78. Higher scores indicate better function.

    Least Squares Mean is actually an adjusted mean change from baseline.


  2. Change From Baseline in Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) Total Score After 12-week Treatment [ Time Frame: Baseline and 12 weeks ]

    The CDR-SB is obtained through semi-structured interviews of patients and informants, and cognitive functioning was rated in 6 domains of functioning: memory, orientation, judgment and problem solving, community affairs, home and hobbies and personal care.

    Each domain was rated on a 5-point scale of functioning as follows: 0-no impairment; 0.5-questionable impairment; 1-mild impairment; 2-moderate impairment and 3-severe impairment. Only personal care was scored on a 4-point scale without a 0.5 rating available. The higher the score, the greater the severity of dementia. Least Squares Mean is actually an adjusted mean change from baseline.


  3. Change From Baseline in Alzheimer's Disease Assessment Scale-cognitive Subscale (ADAS-cog11) Total Score After 12-week Treatment [ Time Frame: Baseline and 12 weeks ]
    Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog11) is an 11-item cognitive subscale that objectively measures memory, language, orientation, and praxis with a total score range of 0 to 70. The greater the dysfunction, the greater the score. Least Squares Mean is actually an adjusted mean change from baseline.

Layout table for eligibility information
Ages Eligible for Study:   55 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  • Male and female patients with an age of at least 55 years
  • Body weight not lower than 50 kgs
  • Patients with a confirmed diagnosis of prodromal Alzheimer's Dementia (AD) on neuropsychological testing defined as:

Mini-Mental State Examination (MMSE) score: greater or equal 24 and a global Clinical Dementia Rating (CDR)-score of 0 or 0.5 and

Free and Cued Selective Recall Reminding Test (FCSRT) score:

free recall test: lower or equal 20 (out of 48) and total recall test: lower or equal 42 (out of 48)

Patients who do not reach the required score in FCSRT will additionally perform the Wechsler Memory Visual Paired Associates test. If the Wechsler Memory Visual Paired Associates test shows a cognitive deficit worse than 1 standard deviation to the mean (compared to the reference values of age and educational norms for inclusion), then the patients can be considered to be eligible for the study.

  • Confirmation of abnormal markers of AD pathology either via a), or alternatively b) mentioned below:

    1. Presence in cerebrospinal fluid of (samples taken within past 4 months may be eligible,:

      low Aß1-42 concentrations (< 640 pg/mL) and increased total tau concentrations (> 375 pg/ml), or / and low Aß1-42 concentrations (< 640 pg/mL) and increased phospho-tau concentrations (> 52 pg/mL in cerebrospinal fluid), or

    2. Abnormal amyloid deposition in a cerebral Positron Emission Tomography (PET) scan. Scans performed in the past according to the recommendation in the protocol are acceptable
  • Patients who have not received prescribed drugs for treatment of AD (including acetyl cholinesterase inhibitors (donepezil, galantamine, rivastigmine, tacrine, phenserine) and Memantine within three months prior to screening
  • Patients must have at least 6 years of formal education and fluency in the test language as verbally confirmed by the patient and documented by the study investigator.
  • Patients must have given written informed consent in accordance with Good Clinical Practice (GCP) and local legislation prior to any study procedures. All patients must be able to give informed consent personally and have capacity for such consent. An informed consent given by a legal representative will not be accepted.
  • Patients must have a reliable study partner (per investigator judgement, for instance a family member, partner, guardian etc.)

Exclusion criteria:

  • Mild cognitive impairment with any etiology other than prodromal AD (for example: neurosyphilis, craniocerebral trauma, small vessel disease) based on clinical data and/or current laboratory findings and/or a pre-existing MRI or CT of the brain (CCT). If previous cranial imaging is not available or older than 12 months prior to screening then a CCT or MRI needs to be performed at screening
