Background and study aims
Chondroitin sulfate is a substance found naturally in the human body. It is taken as a supplement for joint problems. This study aimed to investigate the bioavailability (how much of a substance enters the bloodstream) and pharmacokinetics (the way a substance medicine moves inside the body) of chondroitin sulfate after healthy volunteers took Condrosulf® tablets containing chondroitin sulfate and also to investigate whether the tablets had any side effects.

Who can participate?
Healthy men and women aged 30-65 years inclusive

What does the study involve?
Participants received a single 1600 mg dose of chondroitin sulfate tablets on two separate days, once after they had eaten no breakfast and once after they had eaten a substantial breakfast. Blood was taken at intervals before and after the tablets were taken.

What are the possible benefits and risks of participating?
Chondroitin sulfate is widely used and is considered safe. No potential risks were foreseen for the subjects enrolled in the present study. In previous clinical studies, the most common side effects involved the gut, i.e. indigestion and abdominal pain, and the nervous system, i.e. headache (which occurred in less than 10% of patients). Nausea, constipation, dizziness and skin disorders (rashes) occurred in less than 1% of patients. However, as with all products, the appearance of known or not yet known allergic reactions or side effects couldn't be ruled out.
No potential benefits were foreseen to volunteers participating to the current study with the exception of the medical tests that were performed during it.

Where is the study run from?
CROSS Research S.A. Phase I Unit Clinical Centre (Switzerland)

When is the study starting and how long is it expected to run for?
February 2020 to June 2021

Scientific titleFood effect study of Condrosulf® chondroitin sulfate tablets in healthy male and female volunteers
Study objectivesThe objective of the study was to investigate the effect of food on the bioavailability of total chondroitin sulfate* after single dose of Condrosulf®, administered under fed and fasting conditions to healthy male and female subjects.
*Note: chondroitin sulfate was calculated as the sum of ΔDi-4S, ΔDi-0S, ΔDi-6S disaccharides

InterventionInvestigational product: Condrosulf®, chondroitin sulfate 800 mg tablets, IBSA Institut Biochimique SA, Switzerland.
A single 1600 mg dose of chondroitin sulfate tablet was administered in each of two consecutive study periods, under fed and fasting conditions, according to a two-way cross-over randomized design. The investigational product was administered as two 800 mg tablets to be taken consecutively with 240 ml of still mineral water. A wash-out interval of at least 7 days elapsed between the consecutive administrations. Subjects allocated to treatment under fed conditions were provided with a standardized high-fat high-caloric breakfast 30 min pre-dose. They had to completely eat their breakfast within 30 min and before investigational product administration. Subjects allocated to treatment under fasting conditions didn't receive any food before administration.
