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 2.
Setup and duration of the study
Part 2 of this study will consist of 1 period during which you will stay in our clinical research center in Groningen, location UMCG for 20 days (19 nights). During Part 2 of this study you will receive the study drug or placebo once a day in the form of an oral tablet.
The screening process is devided into several visits and will take place in the medical screening center in Groningen, location Martini.
- First screening: a blood sample will be taken to determin your metabolism
- Second screening: Actual screening and first semen sample
- Third screening: Second semen sample
- Forth screening: After approval from the first 3 screenings you will bring a separate visit to the Keizer Clinic in Assen to undergo a gastroscopy. A gastroscopy is a save examination.
Volunteers who have had a vasectomy are allowed to participate but have no semen collection. Collection of several semen samples at screening, at follow-up and at day 105 and day 109.
Blood samples will be taken and urine will be collected regularly during the study. Besides this also a gastroscopy will take place three times (on screening, during study and if necessary at follow-up). The target of the study compound administered in this study is the muscle tissue. To investigate the amount of study compound that has reached the muscle tissue a muscle biopsy will be taken in the clinic once.
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
