Information sheet PRA-179751
Type of study
The purpose of the study is to investigate the effect of multiple doses of 2 commonly used drugs (itraconazole or fluconazole) on how quickly and to what extent the study drug is absorbed and eliminated from the body. The safety of the study drug and how well it is tolerated when it is administered to healthy volunteers with and without itraconazole or fluconazole will also be investigated.
The study drug is not yet approved for general use but has been given to humans before in research studies conducted to obtain its approval. The study will only take place after it has been approved by the Independent Ethics Committee.
Setup and duration of the study
The study will consist of 2 periods of residency in the clinic. During period 1 you will stay in our research facility in Groningen (Martini site) for 7 days (6 nights), followed by 2 further short non-residential visits. During period 2 you will stay in our research facility for 6 days (5 nights), followed by 3 further short non-residential visits over the next 3 days.
In each period you will receive 1 dose of CBD (2 doses in total during your participation in the study) as an oral solution. Between period 1 and period 2 you will take either itraconazole or fluconazole as oral capsules daily at home.
Risks and medical supervision
CBD is a new study drug that may be used for the treatment of neurological conditions. It is extracted from cannabis plants under highly controlled conditions to ensure the product is always the same. In previous studies with CBD from this Sponsor, CBD has not been associated with the potential euphoric effects that have been documented with recreational cannabis use.
Itraconazole and fluconazole are approved medicines for the treatment of fungal and yeast infections. Itraconazole has been on the market since 1992, fluconazole since 1988.
You will be under strict medical supervision during the study. Before the study and at the end of the study you will undergo extensive medical screening. All potential drugs can cause side effects; the extent to which this occurs differs in each person.
Conditions for participation
You are a healthy male or female between 18 and 60 years old. You can only take part in the study if you do not smoke. Women must be postmenopausal for at least one year or have been surgically sterilized. The study will be conducted under standardized conditions. Use of your own medication, alcohol, regular (caffeine-containing) coffee and tea, cola, power drinks, chocolate (including products made of chocolate) and grapefruit (juice) products during the study is not allowed. There will also be restrictions on the use/consumption of these products before the study. Use of decaffeinated coffee and (herbal) teas without caffeine is allowed.
