About this study
Official title: The Role of Pregabalin in the Treatment of Post-Operative Pain in Fracture Patients
This is a randomized, prospective, double-blind pilot study designed to evaluate the potential effectiveness of pregabalin in post-operative pain management for patients who have sustained a fracture.
Read the detailed description
On admission, all patients who have sustained orthopaedic injuries of any type, including pelvis, will be screened. However, only those patients who will undergo a single episode of surgery during this hospitalization to surgically repair only one of their orthopaedic fractures will be interviewed by a clinical research nurse. If the patient meets all criteria for inclusion/exclusion in the study, the attending physician will consent the patient for inclusion in the study. Upon enrollment into the study, the clinical research nurse will obtain a thorough history from the patient concerning prior narcotic use, response to painful events in the past and will record details of the injury. Prior to surgery, the patient will be treated with narcotic pain medication as required in the judgment of the attending physician. The patient will then be randomized before surgery into a placebo group or pregabalin group. The attending physician will be blinded as to which study arm the patient is in.
Two hours before surgery, patients will receive 75mg of pregabalin. Patients will be placed on a patient-controlled anesthesia pump (PCA) for 24 hours. On post-operative day one, the patients will be switched to oral oxycodone as needed with supplementation with IV Demerol for breakthrough pain. In addition, patients will receive either pregabalin 75mg orally (PO) BID, pregabalin 150mg PO BID or placebo beginning on the day of surgery until discharge.
The clinical research nurse will complete a form which records the daily use of each of the post-operative pain medications. She will also ask the patient to complete a Visual Analog Scale (VAS) to assess pain each day while in the hospital.
Upon discharge, the patient will be given study medication (pregabalin, 75mg PO BID, 150mg PO BID or placebo). Rescue medications will be allowed during the study (including post-operative and outpatient periods). Outpatient rescue medications will consist of hydrocodone/acetamenophen (APAP) 7.5mg PO every sic hours (Q6H) as needed (PRN). Patients will be followed for three months as an outpatient.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Pregabalin in people with Post-operative Pain, run by University of Alabama at Birmingham 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 7 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 7 Jan 2014. 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. Some participants in this study may receive a placebo. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
Amount of pain medication in morphine equivalent units used during the hospitalization. (time frame: Screening - 5 - 15 minutes; Consent - 5-15 minutes; Follow-up - three 15-30-minute visits). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00583869, which also lists 3 linked publications.
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 7 Jan 2014.
