About this study

Official title: A Randomised Double-blind Multicentre Equivalence Study With Active Parallel Comparator Group to Evaluate the Efficacy and Safety of Norspan® Patches Versus Tramadol in Subjects With Chronic, Moderate to Severe Osteoarthritis Pain in the Hip, Knee &/or Lumbar Spine.

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.

Read the 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:

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Buprenorphine and Tramadol in people with Osteoarthritis and Pain, run by Norpharma A/S at 1 site in Finland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

Where is the study taking place?

The record lists 1 site in Finland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2010.
