Bunionectomy Study (0000-063)

March 23, 2015 updated by: Merck Sharp & Dohme LLC

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

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.
  • Phase 1

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 to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Masking: DOUBLE

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
ACTIVE_COMPARATOR: Arm 1: Pregabalin 300 mg
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.
ACTIVE_COMPARATOR: Arm 2: naproxen sodium 550 mg
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.
Other Names:
  • naproxen
PLACEBO_COMPARATOR: Arm 3: Placebo
Drug: Comparator: Placebo
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.

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
Measure Description
Time Frame
Total Patient Controlled Analgesic (PCA) Hydromorphone Consumption Over the 24 Hours Post-surgery
Time Frame: First 24 hours following surgery
Total dose (amount) of hydromorphone via patient controlled analgesic (PCA) pump required in the 24 hours post-surgery in each of the treatment arms: placebo, pregabalin 300 mg or naproxen 550 mg.
First 24 hours following surgery

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
Measure Description
Time Frame
Time to First Request of PCA Hydromorphone
Time Frame: First 24 hours following surgery
Time (in hours) to first patient controlled analgesic (PCA) pump use after surgery in each of the treatment arms: placebo, pregabalin 300 mg or naproxen 550 mg.
First 24 hours following surgery
