Key exclusion criteria
1. Accompanying osteoarthritis (OA) of hip of sufficient severity to interfere with the functional assessment of the knee.

2. Secondary OA or rheumatoid inflammatory or any other type of arthritis.

3. Previous and ongoing treatment with oral symptomatic slow acting drugs in OA (SYSADOA) treatment within 2 months before the study (e.g. glucosamine sulphate, chondroitin sulphate, diacerein, piascledine).

4. Requiring arthroplasty within 2 months or anticipating any need for a surgical procedure on the involved joint during the study.
