About this study

Official title: A Single Dose, Randomized, Double-Blind, Parallel Group Study of the Safety and Pharmacokinetics of Buprenorphine TDS (12.5, 25, 50 Mcg/Hour) Vs. Placebo in Patients With Moderate to Severe Pain Following Orthopedic Surgery

The objective of this study is to assess the safety of the buprenorphine transdermal system (5, 10, and 20 mg) in comparison to placebo transdermal system in subjects with moderate to severe pain after orthopedic surgery. The double-blind treatment intervention duration is 72 hours during which time supplemental analgesic medication (intravenous morphine PCA) will be provided to all subjects in addition to study drug.

Read the detailed description

Buprenorphine is a synthetic opioid analgesic with over twenty-five years of international clinical experience indicating it to be safe and effective in a variety of therapeutic situations for the relief of moderate to severe pain. Transdermal systems may offer advantages over currently indicated oral products including ease and convenience of use, improved compliance, possible reduction in patient care, and prolonged and consistent delivery of drug.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. clinical laboratory tests

  2. vital signs

  3. physical examinations

  4. electrocardiograms

  5. elicited opioid side effects

  6. pulmonary function tests (O2 saturation, peak flow, forced expiratory volume, forced vital capacity, respiratory rate, and respiratory depression/hypoxia)

  7. adverse events

  8. application site skin observations

  9. plasma concentrations of buprenorphine at hours 0, 2, 4, 6, 12, 24, 30, 36, 48, 54, 60, 72, 78, or at early termination

Secondary outcomes (4)
  1. pain intensity

  2. acceptability of therapy

  3. quality of sleep

  4. rescue dose usage

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Buprenorphine transdermal delivery system in people with Postoperative Pain, run by Purdue Pharma LP at 1 site in United States.

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 3 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 19 Apr 2006. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

clinical laboratory tests. The study lists 9 primary outcomes in all. 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 19 Apr 2006.
