About this study

Official title: Randomized Prospective Study Comparing Variable Gabapentin Dosages for Postoperative Analgesia Following Open Thoracotomy

Gabapentin is a nerve medication that treats pain. The specific aim of the study is to compare the difference in the postoperative use of no gabapentin, 300 mg gabapentin 3x daily, or 300 mg gabapentin once at night. Our hypothesis is that higher doses of gabapentin will correlate with decreased pain at the incision and chest tube sites and decreased opioid consumption.

Read the detailed description

The purpose of this study is to determine the effectiveness of various dosages of gabapentin, as part of an ERAS protocol, for postoperative analgesic control after open thoracotomy and additionally determine if there is a correlation of the dosage of gabapentin with pulmonary complication and impaired cognition postoperatively.

Given the widespread use of gabapentin and the huge variability in dosing, our study aims to simplify ERAS protocols for thoracotomy by figuring out the optimal dosing of gabapentin and whether its use overall decreases postoperative opioid consumption and complications.

The specific aim of the study is to compare the difference in the postoperative use of no gabapentin, 300 mg gabapentin 3x daily, or 300 mg gabapentin once at night.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Gabapentin in people with Thoracotomy and Pain, Postoperative, run by Indiana University 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 3 inclusion and 9 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: stopped early, as of the sponsor's last update on 21 Mar 2024. 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. 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?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Mar 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Primary Endpoint of This Study Will be Incision and Chest Tube Site Pain Scores. (time frame: 1 hour after surgery). The study lists 5 primary outcomes in all. 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 NCT05172570, which also lists 14 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 21 Mar 2024.
