About this study

Official title: A Randomized, Double-Blind, Multicenter, Placebo-Controlled Study to Determine the Efficacy and Safety of BTDS Compared to Placebo in Subjects With Moderate to Severe Osteoarthritic Pain of the Hip or Knee

The primary objective of this study is to evaluate the efficacy and safety of BTDS compared to placebo in subjects with moderate to severe osteoarthritic pain of the hip or knee.

Read the detailed description

The primary objective of this study is to evaluate the efficacy and safety of buprenorphine transdermal system (BTDS) compared to placebo in subjects with moderate to severe osteoarthritic pain of the hip or knee who have a sub-optimal response to their non-opioid analgesic treatment and require opioid analgesics for pain control.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Buprenorphine Transdermal System in people with Pain and Osteoarthritis, run by Mundipharma K.K. at 28 sites in Japan.

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 2 inclusion and 1 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?

The record says: finished, as of the sponsor's last update on 15 Apr 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 28 sites in Japan. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The time to the development of inadequate analgesia (time frame: Up to 12weeks). 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 15 Apr 2008.
