Study of Octagam (Intravenous Immunoglobulin [IVIG]) 10% on the Treatment of Mild to Moderate Alzheimer's Disease
April 2, 2014 updated by: Octapharma
Prospective 24-week, Double-blind, Randomised, Placebo-controlled, Multicenter Study Evaluating Safety and Change in Efficacy-related Surrogate Parameters in Patients With Dementia of the Alzheimer's Type Under Treatment With Increasing Dosages of Intravenous Immunoglobulin (Octagam 10%)
This study evaluated the effect of 6 or 12 infusions of different doses of octagam (intravenous immunoglobulin [IVIG]) 10% on the reduction of amyloid beta peptide (Aβ) in cerebral spinal fluid (CSF) and on the increase of Aβ in blood plasma in patients with mild to moderate Alzheimer's disease.

Detailed Description
Participants received 12 infusions of 0.1 g/kg, 0.25 g/kg, or 0.4 g/kg body weight octagam 10% at 2-week intervals (±3 days) or 6 infusions of 0.2 g/kg, 0.5 g/kg, or 0.8 g/kg body weight octagam 10% at 4-week intervals (±5 days).
The effect of the infusions on the reduction of Aβ peptide in CSF and the increase of Aβ peptide in blood plasma was evaluated.

Change From Baseline in the Clinical Dementia Ratio, Sum of Boxes (CDR-SOB) Score at Week 12 and Week 24
Time Frame: Baseline to Week 24
|
A semi-structured interview was conducted by a physician, neuropsychologist, psychometrician, or certified study coordinator with the patient and a caregiver.
Based on the results of the interview, the patient was rated on 6 domains of cognition and function: Memory, orientation, judgment/problem solving, community activities, home and hobbies, and personal care.
Each domain is rated from 0 = no dementia; 0.5 = questionable dementia, mild cognitive impairment; 1 = mild dementia; 2 = moderate dementia; 3 = severe dementia.
The total score ranges from 0 to 18 with a higher score indicating more dementia.
A negative change score indicates improvement.

Baseline to Week 24
|
Change From Screening in Whole Brain and Hippocampal Volume at Week 12 and Week 24
Time Frame: Screening to Week 24
|
The volume of the whole brain and of the left and right hippocampus was measured using high-resolution structural coronal 3D heavily T1-weighted gradient-echo sequence magnetic resonance imaging.
All evaluations were done centrally by Professor Frederik Barkhof at the Image Analysis Centre, VU Medical Center, Amsterdam, Netherlands.
A negative change score indicates loss of brain volume.

|
Left and Right Hippocampal Cerebral Glucose Metabolism at Baseline and at Week 24
Time Frame: Baseline to Week 24
|
Cerebral glucose metabolism was measured in validated 3 dimensional statistic surface projection analysis (Cortex ID®, GE Healthcare), transversal/coronal/sagittal-slice analysis (HERMES BRASS), and voxel-wise whole brain analysis (SPM5) using [18F]fluorodeoxyglucose positron emission tomography.
