Brief summary

The primary objective of this clinical research is to establish the effects of a standardised green-lipped mussel lipid extract (PCSO-524) in women and men with osteoarthritis (OA) of the knee. The study seeks to determine the effective dosage and will be conducted using an open-label design and is categorised as a Phase II clinical trial. Participants meeting the enrolment criteria will be randomised to either 200mg or 400mg daily for a 12 week period. The primary validated measurement will be the Comprehensive Osteoarthritis Test (COAT) which we developed in previous clinical trials on OA. The results will be used to inform a Phase III randomised controlled study.

Interventions
