Primary Outcome Measures:
  • Explore the capacity of 2 dosage levels of ACC-001 plus QS-21 to remove brain fibrillar Aβ in subjects with early AD. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Evaluate the safety and tolerability of 2 dosage levels of ACC-001 plus QS-21 in subjects with early AD. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change from baseline in disease biomarkers. [ Time Frame: study duration ] [ Designated as safety issue: No ]
  • Change from baseline in measurements of immunogenicity. [ Time Frame: study duration ] [ Designated as safety issue: No ]
  • Change from baseline in cognitive and functional scales. [ Time Frame: study duration ] [ Designated as safety issue: No ]
  • Change from baseline in health outcome measures. [ Time Frame: study duration ] [ Designated as safety issue: No ]
