Beskrivelse

Inclusion Criteria:

  • Ages ≥55 and ≤85 years

  • Clinical diagnosis of dementia due to probable AD consistent with criteria established by a workgroup of the National Institute on Aging and the Alzheimer's Disease Association
  • Clinical decline within 12 months before screening and onset of symptoms at least 12 months or longer before screening, which may include any documented cognition, functional, or other objective assessment or the clinical judgment of the investigator or the subject's referring physician that the subject has experienced a clinical decline within the last 12 months
  • Magnetic resonance imaging (MRI) or computed tomography (CT) scan performed within 12 months before screening, with findings consistent with the diagnosis of dementia due to AD without any other clinically significant comorbid pathologies. If an MRI or CT scan is unavailable or occurred greater than 12 months before screening, this assessment should be completed and the findings confirmed before the subject enters the run-in period (Day -14) (copy of the report will be available at the study site)
  • Mini-Mental State Examination (MMSE) score ≥14 and ≤24 at screening and confirmed on Day 1 prior to randomization (fluctuations of ±2 points are acceptable on Day 1/baseline)
  • Clinical Dementia Rating Global score (CDR-GS) ≥1 (at least mild dementia) at screening and confirmed on Day 1 prior to randomization
  • Modified Hachinski Ischemic Scale (mHIS) score ≤4 at screening
  • Fertile, sexually active subjects (men and women) must use an effective method of contraception during the study. Female subjects and the female partner of male subjects must be surgically sterile (hysterectomy or bilateral tubal ligation), postmenopausal for at least 1-year, or willing to practice adequate methods of contraception if of childbearing potential (defined as consistent use of combined effective methods of contraception [including at least 1 barrier method])
  • Reliable and capable support person/caregiver, who if not living in the same household, interacts with the subject approximately 4 times per week and will be available to attend clinic visits in person when possible
  • Subject living at home, senior residential setting, or an institutional setting without the need for continuous (ie, 24-hour) nursing care
  • General health status acceptable for participation in a 26-week study
  • Fluency (oral and written) in the language in which the standardized tests will be administered
  • Receiving a stable dose of an acetylcholinesterase inhibitor (AChEI) (donepezil, rivastigmine or galantamine) for at least 3 months (90 days) before screening and with continuous dosing for at least 6 months OR not presently receiving an AChEI (at least 30 days before screening), but with a history of previous AChEI treatment (subjects receiving donepezil 23 mg currently or within 3 months before screening are ineligible)

Exclusion Criteria:

  • Exposure to an experimental drug, experimental biologic or experimental medical device within 2 months (60 days) before screening
  • Prior participation in an amyloid vaccination clinical study at any time in the past or completion of a passive amyloid vaccination study within 6 months before screening
  • Inability to swallow a tablet
  • In the judgment of the investigator, inability of the subject or the support person/caregiver to complete a 26-week study
  • Inability to be ≥75% compliant with single-blind study drug
  • Inability to adequately cooperate or complete the cognitive testing procedures or any study assessment
  • Residence in a skilled nursing facility

  • Clinically significant (in the judgment of the investigator) abnormal serum electrolytes (sodium, potassium, magnesium) after repeat testing
  • Clinically significant untreated hypothyroidism (if treated, thyroid-stimulating hormone level and thyroid supplementation dose must be stable for at least 6 months before screening)
  • Insufficiently controlled diabetes mellitus (in the judgment of the investigator) or requiring insulin
  • Renal insufficiency (serum creatinine >2.0 mg/dL)
  • Malignant tumor within 3 years before screening (except squamous and basal cell carcinoma or cervical carcinoma in situ or localized prostate cancer)
  • Female subjects who are pregnant, nursing, or planning to become pregnant during the study
  • Unstable medical condition that is clinically significant in the judgment of the investigator
  • Alanine transaminase (ALT) or aspartate transaminase (AST) >2.5 times the upper limit of normal
  • History of myocardial infarction or unstable angina within 6 months before screening
  • History of more than 1 myocardial infarction within 5 years before screening
  • Clinically significant (in the judgment of the investigator) cardiac arrhythmia (including atrial fibrillation), cardiomyopathy, or cardiac conduction defect (subjects with a pacemaker are acceptable)
  • Symptomatic hypotension or hypertension (supine diastolic blood pressure >95 mmHg) (in the judgment of the investigator)
  • Clinically significant abnormality on screening or baseline electrocardiogram (ECG), including but not necessarily limited to a confirmed corrected QT interval (QTc) value ≥450 msec for males or ≥470 msec for females. In subjects with a QRS value >120msec, those with a QTc value <500 msec may be eligible following discussion with the Medical Monitor.
  • Stroke within 18 months before screening, or history of a stroke concomitant with onset of dementia
  • History of brain tumor, subdural hematoma, or other clinically significant (in the judgment of the investigator) space-occupying lesion on CT or MRI
  • Head trauma with clinically significant (in the judgment of the investigator) loss of consciousness within 12 months before screening or concurrent with the onset of dementia
  • Onset of dementia secondary (in the judgment of the investigator) to cardiac arrest, surgery with general anesthesia, or resuscitation
