Except subjects treated with high-potent opioid analgesics for up to four continuous weeks for their OA pain beyond 3 months prior to the Pre-screening Visit.
- Subjects treated with high-potent opioid analgesics (e.g. morphine, fentanyl, oxycodone, methadone, hydromorphone, ketobemidone, buprenorphine (incl. Norspan® patches)) within four weeks prior to the Pre-screening Visit due to non-OA pain.
- Subjects treated with more than 200 mg Tramadol daily or 200 mg codeine daily during the last two weeks prior to the Pre-screening Visit.
