AC Immune brings treatment for Alzheimer’s disease into the Down syndrome population08.01.2016 08:11
Yesterday plans were announced to conduct the world’s first clinical trial for a vaccine targeting Alzheimer’s disease-like characteristics in those with Down syndrome. US NIH provides significant funding with an additional grant from the LuMind Research Down Syndrome Foundation.
The study will test AC Immune’s vaccine ACI-24 and is being conducted in collaboration with the University of California, San Diego (UC San Diego) Down Syndrome Research and Treatment Center. Funding is provided by a significant grant from the US National Institutes of Health (NIH) and an additional grant from the LuMind Research Down Syndrome Foundation. This is the first public/private collaboration for a clinical trial in the field of Down syndrome.
Individuals with Down syndrome (DS) have an extra copy of chromosome 21 which carries the gene for APP encoding the precursor protein of Abeta, one of the hallmarks of Alzheimer’s disease (AD). An important consequence is that individuals with DS develop AD-like characteristics at a rate three to five times greater than that of the general population and at a much younger age. Further, AD-like characteristics develop in more than 98% of people with DS over age 40 with up to 80% developing associated dementia over the age of 60. It is estimated that there are 6 million people with DS worldwide, with 400,000 in the United States.
Trial participants will be adults with DS. The objectives of the trial include studying safety and tolerability of ACI-24, its effect on induction of antibodies against Abeta, clinical and cognitive measures in adults with DS and its effect on biomarkers of AD-like pathology in DS. Participants in the study will be treated for 12 months, with 12 months follow up.
Prof. Andrea Pfeifer, CEO of AC Immune, said: “We are very pleased to bring this potentially disease modifying treatment for Alzheimer’s disease into the vulnerable, genetically predisposed Down syndrome population. The combined knowledge and resources of AC Immune, UC San Diego, NIH and the LuMind Research Down Syndrome Foundation should generate much needed insight for treating the Alzheimer’s-like characteristics of those with Down syndrome. Additionally, this ground-breaking clinical trial could enhance our understanding of early intervention and prevention of Alzheimer’s in general.”
