Plain English summary of protocol
Background and study aims
This is a study of the way food affects the ways a drug is processed by the body. 'Bioavailability' is the amount of the active substance of medicine that reaches the blood flow while the 'pharmacokinetics profile' describes the way the medicine behaves inside the body, after administration, i.e. the absorption, distribution, metabolism and elimination of the substance.
This study is designed to investigate the food effect on the bioavailability and the pharmacokinetics profile of an oral formulation of diclofenac epolamine (DHEP) tablets (each tablet contains 65 mg of diclofenac epolamine corresponding to 50 mg of diclofenac sodium), when administered under fed and fasting conditions to healthy subjects. Diclofenac is a medicine that reduces inflammation and pain.
Who can participate?
Healthy women and men, 18 - 55 years old, can participate. They must comprehend the full nature and purpose of the study, including possible risks and side effects and co-operate with the investigator to comply with the requirements of the entire study. Women of child-bearing potential must be using at least one reliable method of contraception.
What does the study involve?
The study will be conducted at the CROSS Research S.A. Phase I Unit Clinical Centre, in Arzo, Switzerland. Study participants will receive a single oral dose of diclofenac epolamine tablets, under fasting conditions and on a full stomach, in 2 periods, with an interval of at least 5 days between administrations. The formulation to be tested is not yet available on the market in Switzerland, and should therefore be considered a trial product. Participants will have blood samples taken and vital parameters recorded at regular intervals.
What are the possible benefits and risks of participating?
Participating in this study will not bring any direct benefit to participants, with the exception of the medical tests that will be performed during it. As single doses of diclofenac will be administered during this study, no particular risks are expected. However, as with all products, the appearance of allergic reactions or side effects that are known or not yet known cannot be ruled out.
Where is the study run from?
The study will be conducted at the CROSS Research S.A. Phase I Unit Clinical Centre, in Arzo, Switzerland.
When is the study starting and how long is it expected to run for?
August 2019 to November 2019.
