Evidence Hub

A Randomized, Double-Blind, Multicenter Study Evaluating The Safety and Efficacy of BTDS in Subjects With Moderate to Severe Osteoarthritis Pain. Includes a 52-Week Extension Phase

ClinicalTrials.gov · TERMINATED, 2005

188 participants

Abstract

The original objective of this study was to demonstrate the effectiveness and tolerability of the buprenorphine transdermal system (BTDS) 20 micrograms (mcg)/hour (h) in comparison to the buprenorphine transdermal system 5 mcg/h in subjects with moderate to severe osteoarthritis pain currently treated with oral opioids. The double-blind treatment intervention duration is 12 weeks during which time supplemental analgesic medication (acetaminophen or ibuprofen) will be provided to all subjects in addition to study drug.

This study was terminated early due to administrative reasons with only 20% of the planned sample size; therefore, the primary objective was changed to focus on the safety evaluation.

Conditions: Osteoarthritis.

Primary outcome: The Number of Participants With Adverse Events (AEs) as a Measure of Safety..

Enrollment: 188 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 188 participants or records.
