Efficacy and Safety of Diclofenac DDEA 2.32 % in Patient Suffering From Knee Osteoarthritis (OA)
This study will evaluate the efficacy and safety of diclofenac DDEA 2.32 % in patient

 per day, for not less than 10 days out of the 14 days preceding the screening visit
 and also within the 24 hours preceding the screening visit; 5. Be able to tolerate
 rescue medication with only 500 mg paracetamol (APAP) taken in doses of 1-2 tablets up

 Exclusion Criteria:

 - 1. Partial or total replacement of either knee joint, past or planned/expected during
 study duration.

 2. OA of the knee due to other underlying conditions, such as gout, chondrocalcinosis,
