Biological: CB-AC-02


① Group1: CB-AC-02, 2.0 x 10^8 cells on day 0

② Group2: CB-AC-02, 2.0 x 10^8 cells, on day 0 and on week 4 (repeated injection)

② Arm2: K-MMSE 10~19 CB-AC-02, 2.0 x 10^8 cells on day 0 and on week 4 (repeated injection)

Placebo Comparator: Placebo
Subjects with Alzheimer's disease Intervention: Placebo
Biological: Placebo


Placebo on day 0 and on week 4 (repeated injection)

Primary Outcome Measures :
  1. Number of Adverse Events [ Time Frame: 48 weeks ]

    Number of subjects with treatment-related adverse events.

    The safety and tolerability of treatment with CB-AC-02 will be assessed by analysis of adverse events, abnormal findings on physical examinations, standard laboratory tests.

Secondary Outcome Measures :
  1. Changes from the baseline in ADAS-Cog (Azheimer's disease Assessment Scale - Congintive Subscale) Score [ Time Frame: 48 weeks ]
  2. Changes from the baseline in K-MMSE (Korean-Mini Mental Status Examination) Score [ Time Frame: 48 weeks ]
  3. Changes from the baseline in GDS (Global Deterioration Scale) [ Time Frame: 48 weeks ]
  4. Changes from the baseline in CDR (Clinical Dementia Rating) Score [ Time Frame: 48 weeks ]
  5. Changes from the baseline in K-IADL (Korean Instrumental Activities of Daily Living) Score [ Time Frame: 48 weeks ]
  6. Changes from the baseline in CGA-NPI (Caregiver Administered-Neuropsychiatric Inventory) Score [ Time Frame: 48 weeks ]
  7. Change in CIBIC (Clinician Interview Based Impression of Change)-plus [ Time Frame: 48 weeks ]
  8. Changes from the baseline in SF-36 [ Time Frame: 48 weeks ]
  9. Changes in Amyloid Beta and Tau amount (pg/mL) in CSF (Cerebrospinal fluid) [ Time Frame: 48 weeks ]
  10. Change in Brain MRI (Magnetic Responance imaging) [ Time Frame: 48 weeks ]
  11. Change from the baseline of CMRglc (cerebral metabolic rate for glucose ) analyzed with SPM (statistical parametric mapping) with Brain FDG PET imaging [ Time Frame: 48 weeks ]
  12. Changes from the baseline of Amyloid amount analyzed with SPM (statistical parametric mapping) with amyloid PET imaging [ Time Frame: 48 weeks ]
  13. Changes of band power in qEEG (Quantitative electroencephalography) [ Time Frame: 48 weeks ]
