Study summary

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.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 1, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
