Primary Outcome Measures:
  • The incidence and severity of treatment-emergent adverse events (TEAEs). [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
  • Clinically important changes in safety assessment results. [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To assess the immunogenicity of each dose level of ACC-001 with or without QS-21 in subjects with mild to moderate AD. [ Time Frame: 24 months ] [ Designated as safety issue: No ]
  • Change from baseline blood levels of anti A-beta immunoglobulin G (IgG) and immunoglobulin M (IgM) [ Time Frame: 24 months ] [ Designated as safety issue: No ]
