The research physician about this research

Additional information

  • The study compound is being developed for the treatment of brain disorders, like Alzheimer's disease and Parkinson’s disease. Alzheimer's disease is a brain disorder that slowly causes memory loss, confusion, and changes in behavior. Parkinson's disease is a nervous system disorder that causes shaking, stiffness, and difficulty with movement.
  • In this clinical trial, we will investigate how the study medicine is processed and eliminated by the body and how well it is tolerated when it is used by healthy participants. In part A and B, the effects of the study compound are compared to the effects of a placebo (drug with no active ingredient).
  • The study compound or placebo will be administered as a capsule (by mouth) or a cloudy drink. The method of dosing depends on which part you participate in.
  • The trial consists several parts. Part A will be divided in two groups: group A1 and group A2. In group A1 and A2 you will receive the study compound or placebo a total of four times during four different study periods. In part B you will receive the study compound or placebo twice a day for 10 days. 
  • Only for group A1: cerebrospinal fluid (CSF) will be collected from you during your stay. For group 1A, a CSF sample will be collected once after the administration of the study compound via a lumbar puncture. This is done by inserting a thin needle between two vertebrae in the lower back. This procedure is not entirely without risk. Collecting this fluid is important because it provides an indication of the levels of study compound and its possible effects in the brain. The lumbar puncture will be performed by an experienced specialist. The specialist will use numbing medication to minimize any pain or discomfort from the needle.
  • During the study, your heart will be constantly monitored once (part A) or twice (part B) around the administrations for 14 hours. You will get sticky patches (electrodes) on your chest that are attached to a device. At various times, you will have to lie still for 10 minutes without moving, talking or sleeping. You also cannot listen to music, watch TV or use a laptop or phone. However, apart from these moments, you may do so.
  • Only for group A1 and group A2: the exact dates for each period are based on the first dosing in the study. These will be confirmed after the first dose.
  • Only for group A2: Based on the results of period 1 to 3, it could be decided that period 4 will not take place.

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 of new compounds to humans. The compound has already been extensively tested in the laboratory and on animals. Nausea and headache are side effects to be expected in humans. We infer this from information from similar drugs which are already approved and the tests conducted in animals. Prior to the medical screening, you will receive written information about the trial, which also describes the possible side effects based on the animal tests. This information will also be discussed with you at the start of the medical screening. You can then ask questions to the screening physician or nurse. 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.

Veelgestelde vragen

If you are participating in a trial for which you have to stay at the research center for longer than ten days, it is sometimes possible to have visitors (in consultation).

During the trial, you may suffer from mild symptoms like headache or nausea. That may be caused by the medication. It might also be caused by needing to fast for the trial, for example. Those side effects are no fun, but fortunately are not dangerous.

Before a medication is tested on people, it has already been studied extensively in a lab. This enables us to predict well which side effects you might get and we can prepare you for them. It almost never happens that participants suffer from unexpected side effects. For example, an allergic reaction to the medication occurs on average once a year.

The amount of money you receive for your participation in a clinical trial is determined by the duration of the trial. The longer the trial takes, the higher the compensation. But there are also other factors that determine the amount of the compensation awarded, such as special medical procedures.

You can participate in a trial a maximum of four times a year. There must be at least 30 days between two trials. Some trials have a longer waiting period.
