Patients with mild cognitive impairment (MCI) are a group recognized at being at high risk of progressing to Alzheimer disease. Treatment of MCI with immunotherapy with intravenous immunoglobulins (IVIG) could potentially reduce the risk of progression to Alzheimer disease.

This study will evaluate the efficacy of intravenous immunoglobulin in patients with MCI over 24 months after the first infusion. This study will also document conversion from MCI to Alzheimer's Disease.

Primary Outcome Measures:
  • Change in ventricular volumetric as measured by MRI [ Time Frame: Baseline and 24 month MRI evaluation ] [ Designated as safety issue: No ]
    Change in ventricular volumetric as measured by MRI at baseline and 24 months following the first infusion of either 0.4 g/kg NewGam or 0.9% saline solution(placebo) every 14 days x 5

Secondary Outcome Measures:
  • Conversion from amnestic mild cognitive impairment (a-MCI) to Alzheimer Disease (AD) [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    The National Institute of Neurological and Communicative Disorders and Stroke - Alzheimers Disease and Related Disorders Association (NINCDS-ADRDA) Alzheimer's Criteria were proposed in 1984 by NINCDS-ADRDA criteria for diagnosing Alzheimer Disease and Clinical Dementia Rating (CDR) will be used to determine conversion from a-MCI to AD.

  • Change in ventricular volume in patients with positive cerebrospinal fluid (CSF) Aβ1-42/CSF P-Tau181P Alzheimer signature [ Time Frame: Baseline and 24 months following infusion ] [ Designated as safety issue: No ]
    MRI assessment at baseline and 24 months following infusion

  • Change in cognitive performance [ Time Frame: Baseline and 4, 8, 12, 16, 20, and 24 months after the first infusion ] [ Designated as safety issue: No ]

    Change in cognitive performance is measured by:

    • Alzheimer Disease Assessment Scale-cognitive subscale (ADAS-cog)
    • Mini Mental State Exam (MMSE)
    • Clinical Dementia Rating (CDR) and Sum of Boxes (CDR-SB)

Estimated Enrollment: 50
Study Start Date: January 2011
Estimated Study Completion Date: November 2017
Estimated Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: intravenous immunoglobulin (IVIG)
IVIG (NewGam 10%)at 0.4 g/kg
Drug: NewGam 10% IVIG

Subjects will be randomized to receive either an infusion of IVIG at 0.4 g/kg or 0.9% saline solution (placebo) every 14 days for two months for a total of five infusions.

Fifty subjects will be enrolled and randomized in a 1:1 IVIG 2.0 g/kg: placebo ratio. Twenty-five subjects will receive IVIG and 25 subjects will receive placebo.

Placebo Comparator: Saline solution
0.9% saline solution
Drug: NewGam 10% IVIG

Subjects will be randomized to receive either an infusion of IVIG at 0.4 g/kg or 0.9% saline solution (placebo) every 14 days for two months for a total of five infusions.

Fifty subjects will be enrolled and randomized in a 1:1 IVIG 2.0 g/kg: placebo ratio. Twenty-five subjects will receive IVIG and 25 subjects will receive placebo.

Detailed Description:

Screening procedures at visit 1 will take place up to 28 days prior to Visit 2 (Day 1) dosing. Screening labs and assessments will be performed during the screening period. A brain MRI will be obtained as standard of care within 6 months prior to the screening period. The first dose of study drug is administered on Day 1. Visits 2 through 6 have a ±1 day window and occur every 14 days over two months. The investigator will determine if a subject is suitable to continue following the missed infusion. Visits 7 through 12 (Month 4 through Month 24) have a ±7 day window.

All study screening data from Visit 1 including laboratory results must be reviewed for study eligibility prior to receiving first dose of study drug. Visit 2 physical exams and neurological exams prior to infusion may occur within 72 hours prior to the first infusion. Prior to infusion, a review of concomitant medications and adverse events takes place to ensure that no excluded medications have been added or medication discontinued or dose changed that were required to have been stable. If the subject continues to be eligible for enrollment, the subject will be randomized, infused with study medication and will remain in the infusion clinic for at least 4 hours following the start of the infusion for safety assessments on Visit 2 (Day 1).
