About this study

Official title: Pilot Study of Oxtellar XR (Oxcarbazepine Extended Release) in Neurology Patients With Trigeminal Neuralgia

To evaluate the affect Oxtellar XR (Extended Release) has on neurology patients with trigeminal neuralgia (TN), and if it impacts their quality of life.

Read the detailed description

Oxcarbazepine has been used off-label for TN for many years, but has a twice daily dosing. With the once daily dosing it should theoretically help with patient adherence and possibly decrease side effects, which is common with extended release formulations. Specifically the investigators are looking at how well tolerated Oxtellar XR is, and if it has the same efficacy as standard treatments. It is a pilot study, so it will be difficult to gather data and have powerful outcomes, but this will give pilot data for future trials. Patients will be screened for inclusion and exclusion criteria and after will participate in 3 visits following the initial one. Various tests will be administered to measure treatment satisfaction and tolerability throughout the visits. The patients will not have to pay for any of the study visits or medications. A parking voucher will be provided as needed.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Oxtellar XR 150Mg Extended Release Tablet in people with Trigeminal Neuralgia, run by University of Colorado, Denver.

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 9 inclusion and 12 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The record says: withdrawn, as of the sponsor's last update on 1 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 was withdrawn before enrolling participants, so there are no results.

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?

Change in pain associated with trigeminal neuralgia (BPI) (time frame: Weeks 2, 6, and 10 following screening). The study lists 2 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 NCT03374709, which also lists 8 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 1 Nov 2019; AzTrials last refreshed its copy on 7 Nov 2026.
