In bacterial infections, foreign bacteria enter the body and start growing there. Such ‘pathogens’ are less likely to cause harm if the immune system is strong enough. If that is not the case, a person becomes ill, for example due to an inflammation. Sometimes antibiotics are then prescribed. These are medicines that kill bacteria or inhibit their growth. The study compound can possibly be used to treat infections that do not respond to antibiotics. It works in a new way by activating your body’s defense system. This study consists of three parts: Part A, Part B, and Part C. Only Part A and Part B will take place at our research center. You can only participate in one part.
In this study, we will investigate how safe the study compound is and how well it is tolerated when it is used by healthy people. Additionally, we will investigate the levels of the study compound in blood and urine. We will also investigate whether the body produces antibodies (an immune response) against the study compound. Furthermore, we will explore the biological activity of the study compound and the presence of anti-rhamnose antibodies. Anti rhamnose antibodies occur naturally present in your body and have a positive effect on your body’s immune system. In Part B, we will see how the study compound affects the bacteria in the gut.
We will compare the effects of the study compound with the effects of a placebo. A placebo is a compound without any active ingredient. Whether you will receive the study compound or placebo will be determined by chance.
You will receive a solution of the study compound or placebo administered directly into a blood vessel through an infusion. In Part A, you will receive the study compound once. In Part B, you will receive the study compound twice daily for 7 days.
All (potential) medicines can cause side effects. Because the compound has not yet been administered to humans, there are currently no known side effects in humans. In rare cases (<0.1%), serious side effects can occur during the first administration to humans. The compound has already been extensively tested in the laboratory and on animals. Prior to the medical screening, you will receive written information about the trial, which also describes the possible side effects based on these animal tests. This information will also be discussed with you at the start of the medical screening. You can then ask the screening physician or nurse any question you may have. The medical screening will only take place after you have given written consent to participate in the trial. We want to emphasize that even after giving written consent, participation in any clinical trial is voluntary. You can decide at any time not to participate or to stop the medical screening or the trial. You do not need to provide a reason for why you no longer wish to participate.
