About this study

Official title: A Placebo-controlled, Randomized, Double-Blind Phase II Clinical Study of Gammagard Intravenous Immunoglobulin (IVIg) for Treatment of Mild to Moderate Alzheimer's Disease

The overall goal of this double-blind Phase II study is to evaluate the safety, efficacy and biological mechanisms of action of Intravenous Immunoglobulin (IVIg) in the treatment of mild to moderate stage Alzheimer's disease (AD). IVIg contains antibodies against the amyloid beta protein that is the central component of the AD senile plaque. It is hypothesized that IVIg treatment will reduce the levels of beta amyloid in the brain and improve cognitive abilities relative to placebo. A total of 24 patients with mild to moderate AD capable of giving informed consent will be randomly assigned to receive either IVIg (16 patients)or saline placebo (8 patients) for six months. This study includes comparison of four dosing regimens of IVIg. Cognitive, behavioral and functional measures will be collected at baseline, three months and six months of treatment. Plasma samples will be collected before and after infusions. Subjects will undergo a lumbar puncture before and after the six months of treatment for cerebrospinal fluid (CSF) biomarker analyses. In addition, Positron Emission Tomography (PET) imaging substudies will be performed at two time points during the study. Following the initial 6 month placebo-controlled period, all participants have the opportunity to receive IVIg for an additional 12 month period in an extension study.

Read the detailed description

Abnormal processing of the beta-amyloid protein is thought to be an early and causative event in the pathogenesis of Alzheimer's disease (AD). Immunotherapy targeting beta amyloid (Aβ) has demonstrated a remarkable capacity to arrest and even reverse elements of AD brain pathology. Intravenous Immunoglobulin (IVIg) is a medication obtained from the pooled plasma of healthy human blood donors that contains natural anti-amyloid antibodies and exhibits potent central nervous system anti-inflammatory properties. IVIg has been FDA-approved and used for more than 25 years in patients with a variety of immune deficiency and autoimmune diseases and has an established safety record, but is not FDA-approved for the treatment of AD.

A total of 24 patients, males and females 50 years of age and older, with mild to moderate Alzheimer's disease (AD) will be enrolled in this research study. To be eligible, patients must meet the National Institute of Neurological and Communicative Disorders and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria for probable AD. After written informed consent is obtained, subjects will go through a screening process to determine if he or she meets the inclusion criteria. Screening procedures include medical history, blood and urine tests, neurologic exam, chest x-ray and MRI. Women who want to take part in this study must either be post-menopausal, surgically sterilized or agree to avoid becoming pregnant during the entire period of their participation in this study.

To be eligible for this research study, patients must be taking a stable dose of an approved AD medication for at least 3 months prior to entering this study or be unable to take these medications. The design of this protocol is that of an add-on study and we will recommend patients continue to take any FDA-approved AD medications they are taking at study entry.

Subjects' participation in the study will last approximately 19 months, including screening and baseline procedures, treatment with study drug and a follow-up visit 1 ½ months after finishing treatment, plus a visit for blood tests 6 months after the last infusion in the study. This research study requires that the patient have another person, (such as a spouse, child, other relative, close friend, aide or other professional caregiver), who will accompany the patient to each clinic visit.

Subjects will be randomized to a treatment group for 6 months of infusions of IVIg or placebo. The treatment groups compare different doses and frequencies of treatment. Patients will have a 33% chance of receiving placebo.

Blood will be obtained from subjects every two weeks and examined in our research laboratories to obtain more information about IVIg's biological effects. Cerebrospinal fluid will be obtained by lumbar puncture twice over the course of the study for the same purpose. Patients will be asked to allow a portion of a blood sample to be used for Apolipoprotein E (APOE) testing and banked for genetic research testing related to AD and aging, but do not have to participate in the testing or allow their blood sample to be stored in order to take part in the study.

Cognitive testing will be carried out at baseline and every three months over a period of 18 months. Results of cognitive testing will constitute the primary endpoint of this study. Positron Emission Tomography (PET) imaging substudies will be performed at two time points during the study. Safety laboratories and assessments will be carried out at regular intervals. Subjects will not be responsible for any research study-related costs but will be responsible for the costs of evaluations required to establish diagnosis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ADAS-Cog

    The Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) is a brief neuropsychological assessment used to assess the severity of cognitive symptoms of dementia. It is one of the most widely used cognitive scales in clinical trials and is considered to be the "gold standard" for assessing antidementia treatments. The ADAS-Cog range from 0 to 70, where higher scores indicate greater cognitive dysfunction.

    Measured: 12 months

  2. CGIC

    The Clinical Global Impression of Change focuses on clinicians' observations of change in the patient's cognitive, functional, and behavioral performance since the beginning of a trial. It relies on both direct examination of the patient and interview of informants. Unlike a targeted symptom scale, it takes into account a subject's overall function in the cognitive, behavioral and functional activity domains. Scoring is based on an interview with the caregiver and examination of the patient by an independent evaluator, without consulting other information such as cognitive test results. The CGIC range from 1 to 7, where 1=very much improved since the initiation of treatment; 4=no change from baseline; 7=very much worse since the initiation of treatment.

    Measured: 12 months
