Safety and Efficacy of the Buprenorphine Transdermal Delivery System in Subjects With Osteoarthritis Pain.

April 29, 2006 updated by: Purdue Pharma LP

A Double-Blind Placebo-Controlled Study of Buprenorphine Transdermal System (BTDS) in Patients With Osteoarthritis of the Hip or Knee

The objective of this study is to assess the safety and efficacy of the buprenorphine transdermal system (5, 10, and 20 mg) in comparison to placebo transdermal system in subjects with osteoarthritis pain. The double-blind treatment intervention duration is 28 days.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • documented history and/or radiologic evidence of chronic osteoarthritis of the hip or knee.
  • receiving opioid therapy for osteoarthritis-related pain within the past year or have experienced pain that was inadequately controlled with a full standard dose of NSAIDs.

Exclusion Criteria:

  • receiving opioids at an average daily dose of greater than 90 mg of oral morphine equivalents or patients receiving more than 12 tablets or capsules per day of short-acting opioid-containing products
  • scheduled to have surgery (including dental) during the study period that involved the use of pre- and/or postoperative analgesics or anesthetics.

Other protocol-specific exclusion/inclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Percentage of patients who were treated successfully for pain management
a patient fails if he or she discontinues early due to ineffective treatment or has a Patient Satisfaction Scale score of poor or fair at the final visit

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Average pain intensity and patient satisfaction scores
Incidence of early discontinuation due to lack of efficacy
Time to early discontinuation due to lack of efficacy
Dose level at end of titration
Investigator's assessment of therapeutic response
Diary pain scores
