Primary Outcome Measures:
  • To measure the change in amyloid beta peptide concentration of the blood plasma from immediately prior to the last IVIG infusion calculated over 2 or 4 weeks. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To measure changes from baseline in MRI, PET scan, neuropsychometric testing results, autoantibody concentrations in the blood and in CSF, CSF tau and pTau concentrations. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Enrollment: 58

Detailed Description:

To evaluate the effect of 12 infusions of 0.1 g/kg, 0.25 g/kg or 0.4 g/kg IGIV 10% at a 2-week +/- 3 days interval or 6 infusions of 0.2 g/kg, 0.5 g/kg or 0.8 g/kg body weight IGIV 10% at a 4-week +/- 5 days interval on the reduction of +/- in the CSF and the increase in the blood plasma in mild to moderate AD patients.
