Detailed Description:

This is a randomised, double-blind, multicentre equivalence study with active comparator, parallel group, to evaluate the efficacy and safety of Norspan® patches versus Tramadol in subjects with OA pain in hip, knee and/or lumbar spine, currently receiving sub-optimal analgesic treatment (defined as BS-11 score > 4) when treated with paracetamol 4000 mg/day or another analgesic at least comparable to this.

The study consist of 4 phases:

Run-in, Wash-out, Double blind and Follow-up

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. 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.

    Or Males & females aged 50 years or more with osteoarthritis in lumbar spine without nerve root pressure.

  2. 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.

    Or Clinical diagnosis of OA in the lumbar spine without nerve root pressure, & with radiographic or CT-scan evidence for lumbar OA.

  3. 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).
  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.
  5. 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).
  6. Subjects must be able to read and comprehend Danish and be willing to sign informed consent.
  7. Subjects must be willing and able to fill in a Subject Diary on a daily basis.

Exclusion Criteria:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Substance or alcohol abuse, or subjects who, in the opinion of the Investigator, have demonstrated addictive or substance abuse behaviour.
  7. Subjects with cancer (except basal cell carcinoma) or history of cancer in the last 5 years (except treated basal cell carcinoma).
  8. 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.
  9. Dermatological disorder at any relevant patch application site that precludes proper placement and/or rotation of patch placement.
  10. Treatment with steroids (oral, intra-muscular, intra-venous, intra-articular, epidural, or other corticosteroid injections) within 6 weeks prior to the Pre-screening Visit and during the study.
  11. Intra-articular hyaluron acid injections given within 6 months prior to the Pre-screening Visit and during the study.
  12. Any joint evacuation carried out within 6 weeks prior to the Pre-screening Visit and during the study.
  13. Subjects who are currently taking monoamine oxidase inhibitors (MAOIs) or have taken MAOIs within 2 weeks prior to the Pre-screening Visit.
  14. Participation in a clinical research study involving a new chemical entity within 3 months prior to the Pre-screening Visit.
  15. Allergies or other contraindications to transdermal systems or patch adhesives.
  16. Known lack of tolerance and/or effect of Tramadol.
  17. Known hypersensitivity (allergic reaction) to opioids or Paracetamol.
  18. Ongoing requirement for and treatment with direct external heat sources such as heat lamps, electric blankets, saunas, heating pads and heated waterbeds.
  19. New physiotherapy and/or chiropractic and/or other non pharmacological regimen scheduled to commence during the Run-in-Phase, Wash-out-Phase or Double-Blind-Phase of the study. This includes physiotherapy and/or chiropractic and/or other non pharmacological regimen not in a scheduled weekly window.
  20. Subjects who cannot or will not cut the hair at the patch site for proper placement of the patch.
  21. Any other contraindications listed in the Summary of Product Characteristics for Norspan® patches or Tramadol.
  22. Subjects, who are unsuitable for any other reason to participate in the study in the opinion of the Investigator.
