Information sheet PRA-133871 (part 1)

Type of study

The purpose of the study is to investigate to what extent the study medication is safe and tolerated. It will also be investigated how quickly and to what extent the study medication is absorbed and eliminated from the body. The study drug is not registered as a drug and has not been given to humans before. The study is already approved by the Independent Ethics Committee.

This study consists of two parts; Part 1 and Part 2. The remainder of this document only refers to Part 1.

Setup and duration of the study

Part 1 of this study will consist of 1 period during which you will stay in our clinical research center in Groningen, UMCG location for 5 days (4 nights). During Part 1 of this study you will receive the study drug or placebo once in the form of an oral tablet.

Blood samples will be taken and urine will be collected regularly during the study.

Risks and medical supervision

Duchenne’s disease causes irreversible damage of muscle tissue and therefore muscle weakness. This muscle weakness is caused by a low calcium concentration in the muscles. The study drug causes the calcium levels to stay on a certain level, so the damage to muscle tissue and muscle weakness could be prevented.

Adverse effects observed during the first parts were: headache, nausea, abdominal pain, stomachache, bloating, flatulence, stomach discomfort, hunger, dry mouth, muscle pain, pain arms, chest muscle stiffness, muscle cramps and pain in the lower jaw, muscle twitching buttock, muscle cramp thigh, itching both hands, lower back pain, skin irritation at holter and ECG stickers, hematoma at venipuncture site, flu, common cold, nasal congestion, postural dizziness, dizziness, transpiration, sore throat, restlessness, tiredness, sleepiness, anxiety, loose stools, cannula site reaction, increased frequency urination, salivation increased, fast heartbeat, nosebleed, pink eye, sore eye, toothache, higher blood levels of liver enzymes, fungal infection in lower part of the esophagus, and erosion of the intestinal wall in the first part of the duodenum and the stomach wall. At this time it is not known if these effects are related to the study compound as the study is still blinded.

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 in Groningen.

Conditions for participation

You are a healthy male between 18 and 45 years old. You can only participate in this study if you do nog smoke or smoke less than 5 cigarettes per day. Since the metabolism of the drug in the body can vary based on ethnicity, only caucasion volunteers can participate.
