Type of study

The study will be performed in 2 parts, Part A and Part B. The purpose of the study is to investigate how safe the study medication is and to what extent the study medication is absorbed and eliminated from the body. In addition, the effect of food will be investigated in group A7 and also the effect of a registered medication for heartburn in combination with the study medication will be investigated.

The study compound is not registered and has not been administered to humans before. It has been previously tested in the laboratory and on animals. This study is not intended to improve your health, but is necessary for the further development of this study medication. The study will only take place after it has been approved by the Independent Ethics Committee.

Setup and duration of the study

For Part A, the study consists for group A1a - A6b of 1 period were you will stay for 6 days (5 nights) in which you will receive the study compound once, after you have fasted for 10 hours. After your clinical stay there will be 2 short visits to our research facility.

The study medication or placebo (medicine without an active ingredient) will be given as a suspension. During the study you will stay in our clinical research center in Groningen (location Martini). Before the start of the study you will visit the medical screening centre. Blood samples will be taken regularly during the study.

Risks and medical supervision

All drugs have the potential to cause adverse events. Because the study compound will be administered to man for the first time, side effects of the study compound in man have not been reported to date. However, the study compound has been studied in animals, only a few abnormalities have been observed. After multiple administrations of high doses mild elevations in some liver enzymes in the blood were observed. After very high doses an increase in the weight of the liver and inflammation of the lining of the stomach were seen.

For group A7 the most observed side effects that occur by using the registered medication for heartburn are: headache, dizziness, constipation and diarrhea.

You should be aware that unknown adverse effects may occur during the study. You will be under strict medical supervision during the study. Before the study and at the end of the study you will undergo an extensive medical screening.
