The goal of this study is to evaluate how safe and effective the new drug ALZ-801 is for the treatment of participants with early-stage Alzheimer’s disease and ApoE4/4 genotype. The study compares the effect of the new drug ALZ-801 with the effect of a placebo (a drug without an active ingredient, a ‘fake drug’). The study drug is taken in the form of a tablet.

ALZ-801 contains an active ingredient called tramiprosate. Tramiprosate disrupts the formation of abnormal forms of a protein called beta-amyloid or Aβ-42. These abnormal amyloid proteins are believed to play an important role in causing cell damage in the brain and in the development of your disease. ALZ-801 interferes with the formation of these abnormal toxic proteins and could possibly slow or stop the worsening of your disease.

You and your study partner, someone who knows you well and can answer questions about your daily functioning, will visit the research center approximately 9 times, during approximately 93 weeks. In addition, you will also have several telephone conversations. The duration of a visit is not always the same because not every visit has the same procedures. Some of these visits may last 6-8 hours, others 3-4 hours. A phone call takes around 15 minutes. The research takes place in Amsterdam, Den Bosch, and Zwolle.

This research is commissioned by Alzheon.
