Bunionectomy Study - Full Text View

Purpose

We are interested in whether bunionectomy can be used as a model to study the treatment of acute pain. It has been used to study the effect of Non-Steroidal Anti-inflammatory (NSAIDS) medications (such as ibuprofen) and other pain relieving drugs. We are interested to know if this model is useful to study other drugs for the treatment of acute pain. The other drugs being tested in this study are pregabalin and naproxen sodium. These drugs are approved for use by the Food and Drug Administration (FDA). This study is designed to test whether these two drugs are effective in treating pain after a bunionectomy.

Condition	Intervention	Phase
Acute Pain	Drug: pregabalin Drug: naproxen sodium Drug: Comparator: Placebo (unspecified)	Phase I

Drug Information available for:

Naproxen sodium Naproxen Pregabalin

U.S. FDA Resources

Study Type:	Interventional
Study Design:	Treatment, Randomized, Double Blind (Subject, Investigator), Placebo Control, Parallel Assignment, Efficacy Study

Official Title:	A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Effect of Pregabalin and Naproxen Sodium on Postoperative Pain After Bunionectomy

Further study details as provided by Merck:

Primary Outcome Measures:

Reduction in the total dose of PCA hydromorphone use [ Time Frame: First 24 hours following surgery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Time to first request of PCA hydromorphone [ Time Frame: First 24 hours following surgery ] [ Designated as safety issue: No ]

Estimated Enrollment:	90
Study Start Date:	July 2007
Primary Completion Date:	December 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Active Comparator Arm 1: pregabalin	Drug: pregabalin Patients will be randomized just prior to surgery to 1 of 3 study treatments: pregabalin (300 mg) treatment will be administered approximately 1 hour prior to surgery. Postoperatively, pregabalin (150 mg) will be dosed starting at 8 hours following T=0 and every 8 hours until 40 hours following T=0.
2: Active Comparator Arm 2: naproxen sodium	Drug: naproxen sodium Patients will be randomized just prior to surgery to 1 of 3 study treatments: naproxen sodium (550 mg) treatment will be administered approximately 1 hour prior to surgery. Postoperatively, naproxen sodium will be dosed starting 12 hours following T=0 and every 12 hours until 36 hours following T=0.
3: Placebo Comparator Arm 3: Pbo	Drug: Comparator: Placebo (unspecified) Patients will be randomized just prior to surgery to 1 of 3 study treatments: placebo treatment will be administered approximately 1 hour prior to surgery. Postoperatively, placebo will be dosed starting at 8 hours following T=0 and every 8 hours until 40 hours following T=0.
