Brief Summary:
AZD0530 is an inhibitor of Src and Abl family kinases1. It has been developed as treatment for malignancies because these kinases play a role in tumor invasion and proliferation. However, the Src family kinases (SFKs) are highly expressed in brain and have major effects on synaptic plasticity2. Moreover, the investigators have recently shown that a specific SFK, namely Fyn, is aberrantly activated by specific conformations of the Amyloid Beta (Aß) peptide from Alzheimer's disease (AD). Genetic deletion of Fyn rescues AD deficits in preclinical models. This clinical trial will test the potential benefit of AZD0530 for Alzheimer's disease modification.

Primary Outcome Measures :
  1. Change in Brain Glucose Uptake Measured Using 18F-FDG PET Imaging [ Time Frame: 12 months ]
    Composite measure of brain glucose uptake using F18-FDG PET in a pre-defined set of brain regions, between baseline and 12 months.

  2. Number of Participants With One or More Serious/Other Adverse Events Subjects With Mild AD as Assessed by Analysis of Adverse Events, Including Symptoms, and Abnormal Findings on Physical and Neurological Examinations, and Standard Labs. [ Time Frame: 12 months ]
    Assessment of any adverse effects between drug and placebo-treated subjects

Secondary Outcome Measures :
  1. The Effect of Treatment With AZD0530 on Cognitive and Behavioral Function [ Time Frame: 12 months ]

    The change in cognitive function between baseline and 12 months will be measured by the following tests:

    1. Alzheimer Disease Assessment Scale - Cognitive 11 (ADAS-cog11). Measures: Cognitive function Maximum score: 70; Minimum score: 0. Higher score equals worse cognitive function
    2. Mini-Mental State Examination (MMSE) Measures: Cognitive Function Maximum score: 30; Minimum score: 0. Higher score equal better cognitive function
    3. Alzheimer Disease Cooperative Study - Activities of Daily Living Inventory (ADCS-ADL) Measures: Ability to perform routine daily activities Maximum score: 78; Minimum score: 0. Higher score equals better ability to perform activities of daily living
    4. Clinical Dementia Rating Sum of Boxes (CDR-SO) Measures: Dementia severity Maximum score: 18; Minimum score: 0. Higher score equals more severe dementia.

  2. Percent Change in Brain Volume Before and After Treatment [ Time Frame: 12 months ]
    Change in volume of pre-defined brain regions between baseline and 12 months of treatment.

  3. Cerebrospinal Fluid Levels of Total Tau, Phospho-tau (p-Tau), and Amyloid-beta 1-42 (Abeta 1-42) [ Time Frame: 12 months ]
    Measure concentration of Tau and Amyloid-beta 1-42 biomarkers in the cerebrospinal fluid between baseline and 12 months of treatment

  4. Change in Brain Glucose Uptake Measured Using 18F-FDG PET Imaging [ Time Frame: 12 months ]
    The results from the primary outcome with brain FDG-PET imaging was analyzed by ApoE genotype. Composite measure of brain glucose uptake using F18-FDG PET in a pre-defined set of brain regions, between baseline and 12 months.

  5. Stability of permitted medications for 4 weeks. In particular:

    • Stable doses of antidepressants lacking significant anticholinergic side effects (if they are not currently depressed and do not have a history of major depression within the past 1 year)
    • Cholinesterase inhibitors and memantine are allowable if stable for 12 weeks prior to screen
  6. Geriatric Depression Scale less than 6 [Note: a score ≥6 on this screening scale may be permissible, if the subject is examined by a site clinician and judged not to be depressed.]
