Norspan® Patches Versus Tramadol in Subjects With Chronic, Moderate to Severe Osteoarthritis Pain in the Hip Knee and/or Lumbar Spine
Finland120 participantsStarted 2007-02
Plain-language summary
The primary objective of this equivalence study is to evaluate the efficacy of Norspan® patches versus Tramadol in subjects with chronic, moderate to severe osteoarthritis pain of the hip, knee and/or lumbar spine.
The secondary objectives are to evaluate the safety and general satisfaction for the patients in the two treatment groups.

Inclusion criteria
. Males and females aged 18 years or more (women of childbearing potential must have a negative pregnancy test, be non-lactating, and willing to use adequate and reliable contraception (defined as IUD, contraceptive pill or depot gestagen) throughout the study) with osteoarthritis in the hip \&/or knee.
. Clinical diagnosis of OA in the hip and/or knee including fulfilment of ACR-criteria and radiographic or MR-Scan evidence for the primary OA-joint in hip \&/or knee.
. Subjects with moderate to severe pain confirmed by a BS-11 score \> 4 for their pain on average in their primary OA-joint during the last 5 days prior to the Baseline Visit (Randomisation Visit/Visit 4).
. Subjects must previously or during Wash-out-Phase have been treated with 4000 mg Paracetamol IR daily or another analgesic treatment at least comparable to this and not have been adequately pain relieved (defined as BS-11 score \> 4 for their pain on average in their Primary OA-joint during 5 continuous days) on that treatment.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Equivalence study to evaluate the efficacy of Norspan® patches versus Tramadol in subjects with chronic, moderate to severe osteoarthritis pain of the hip, knee and/or lumber spine.
. Subjects must be willing to discontinue all other analgesics (incl. glucosamine) at the Pre-Screening Visit (Visit 1) and until the Completion/Discontinuation Visit (Visit 10).
. Subjects must be able to read and comprehend Danish and be willing to sign informed consent.
. Subjects must be willing and able to fill in a Subject Diary on a daily basis.
Exclusion criteria
. Subjects treated with high-potent opioid analgesics (e.g. morphine, fentanyl, oxycodone, methadone, hydromorphone, ketobemidone, buprenorphine (incl. Norspan® patches)) for their OA pain. 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.
. History of chronic condition(s), in addition to OA, requiring frequent analgesic therapy (e.g. frequent headaches, frequent migraine, gout, rheumatoid arthritis) and severe respiratory disease.
. Scheduled for surgery that would fall within all phases (Run-in-Phase, Wash-out-Phase, Double-Blind-Phase and Follow-up-Phase) of the study.
. Substance or alcohol abuse, or subjects who, in the opinion of the Investigator, have demonstrated addictive or substance abuse behaviour.
. Subjects with cancer (except basal cell carcinoma) or history of cancer in the last 5 years (except treated basal cell carcinoma).
. Untreated depression or other psychiatric disorder in such a way that participation in the study may, in the opinion of the Investigator, pose an unacceptable risk to the subject.
