Immune Globulin Intravenous for the treatment of Alzheimer's
Presbyterian Hospital/Weill Cornell Medical Center and Baxter International Inc. (NYSE: BAX) announced results of a six-month, placebo-controlled Phase II study of 24 patients treated with GAMMAGARD S/D and GAMMAGARD LIQUID [Immune Globulin Intravenous (IGIV)] for the treatment of mild-to-moderate Alzheimer's disease today at the American Academy of Neurology (AAN) annual meeting in Chicago. The study met the primary endpoint criteria favoring GAMMAGARD LIQUID and GAMMAGARD S/D over placebo on measures of cognitive function and global impression of change, which are common measures of outcome in Alzheimer's disease clinical trials. The study also met secondary endpoints that measured changes in beta-amyloid and anti-amyloid antibody levels in blood and cerebrospinal fluid. Results show findings indicative of potential efficacy and tolerability. Key findings throughout six months included: measurements of clinical outcome, behavioral outcome and cognitive performance in Alzheimer's patients treated with GAMMAGARD S/D and GAMMAGARD LIQUID compared to placebo. Twelve-to-18 month data will be available later this year.
Secondary endpoint results suggest that levels of antibodies against beta-amyloid were observed to have increased in the blood and cerebrospinal fluid of patients treated with GAMMAGARD S/D and GAMMAGARD LIQUID, while the levels of beta-amyloid increased in the blood. Beta-amyloid is a substance thought to contribute to the degeneration of the brain in Alzheimer's disease. Clearing this substance from the central nervous system, therefore is hypothesized to help remove or reduce the building blocks of Alzheimer's.
The primary and secondary endpoint data were reported by the lead researcher for the trial, Dr. Norman Relkin, director of the Memory Disorders Program and behavioral neurologist and neuroscientist at New York-Presbyterian/Weill Cornell Medical Center, and associate professor of clinical neurology at Weill Cornell Medical College in New York City. "This was the first placebo-controlled clinical trial of GAMMAGARD for Alzheimer's disease and the results are clearly promising," Dr. Relkin commented. Baxter supported the study and provided GAMMAGARD LIQUID and GAMMAGARD S/D for the trial. GAMMAGARD S/D and GAMMAGARD LIQUID, marketed as KIOVIG in the European Union, contain a broad spectrum of immunoglobulins (antibodies) and are indicated as an immunoglobulin replacement therapy that boosts the immune system in patients with primary immunodeficiency disorders. The precise mechanisms of GAMMAGARD S/D and GAMMAGARD LIQUID's effects in Alzheimer's disease are not known. "These study results reflect Baxter's support of innovative science and commitment to meeting a critical, unmet medical need," said Hartmut J. Ehrlich, MD, vice president of global research and development for Baxter's BioScience business. "While results of Baxter's mid-stage development work in Alzheimer's disease treatment are promising, further investigation in a larger Phase III study is required." http://www.medicalnewstoday.com .
