排除标准
- •Patients meeting any of the following criteria must not be included in the study:
- •1.Has had an MRI of the brain within the previous 2 years that showed pathology that would be inconsistent with a diagnosis of AD
- •2.Use of prohibited medications, including memantine
- •3.Has any contraindications for MRI including claustrophobia, the presence of metal (ferromagnetic) implants, or a cardiac pacemaker that is not compatible with MRI
- •4.Has any contraindications to lumbar puncture

The HbA1c value should not be older than 6 months prior to screening. If no recent HbA1c value is available, then HbA1c should be assessed locally.
- •10.History of a seizure disorder andor stroke, unless >5 years ago
- •11.History of alcohol abuse or dependence or drug abuse in the past 5 years
- •12.Uncorrected impairment of vision or hearing that would preclude the patient from taking tests or patients lacking the ability to communicate
- •13.Clinically significant abnormal laboratory values in the opinion of the investigator
- •14.Severe hepatic or severe renal impairment (e.g. bilirubin > 3 x ULN, AST/ALT > 5 x ULN, eGFR < 30 ml/min/1.73m2 or CrCl <30 ml/min)
- •15.Clinically significant B12 deficiency (i.e., no macrocytosis) in the opinion of the investigator
- •16.Severe heart disease (history of myocardial infarction, congestive heart disease, history of unstable angina pectoris, clinically significant ECG abnormality) within 6 months prior to screening. Patients with arterial thrombosis will not be excluded if they are stable for at least 6 months prior to Screening
- •17.Cancer or a malignant tumor within the past 3 years, except patients who underwent potentially curative therapy with no evidence of recurrence.
- •18.Participation in another clinical trial for an investigational agent and having taken at least one dose of study medication, unless confirmed as having been on placebo, within 12 weeks prior to screening. (The end of a previous investigational trial is defined as the date of the last dose of an investigational agent.)
- •19.Participation in a previous clinical trial with T 817MA
- •20.Patients whom the investigator deems to be otherwise ineligible
- •21.Has an MRI of the brain at screening indicative of significant abnormality, including, but not limited to, prior hemorrhage or infarct, large (>1 cm) infarct, >2 lacunar infarcts outside the brain stem, severe white matter changes (Fazekas grade 3), >4 microbleeds, superficial hemosiderosis >1 cm, aneurysm, vascular malformation, subdural hematoma, hydrocephalus, space-occupying lesion (e.g, abscess or brain tumor such as meningioma).
