Trials overseas
This is where the research for Trigeminal Neuralgia is happening right now. Nothing is recruiting in Australia, so the overseas record is the useful one.
40 trials for this disease are open to new participants outside Australia, as ClinicalTrials.gov listed them on 11 October 2026. Voxsanity does not publish a page for any of them; the searches below reach them at the registry.
These overseas counts are likely too high. They come from the registry’s own search, which expands a condition name to related conditions, so some of the trials counted are for a different disease in the same family.

About Trigeminal Neuralgia
The text below is reproduced exactly as its source published it. It has not been edited, shortened or rewritten.
Trigeminal neuralgia (TN) is a type of chronic pain that affects your face. It causes extreme, sudden burning or shock-like pain. It usually affects one side of the face. Any vibration on your face, even from talking, can set it off. The condition may come and go, disappearing for days or even months. But the longer you have it, the less often it goes away. TN usually affects people over 50, especially women. The cause is probably a blood vessel pressing on the trigeminal nerve, one of the largest nerves in the head. Tumors and multiple sclerosis can also cause TN, but in some cases the cause is unknown. There is no specific test for TN. It can be hard to diagnose, since many other conditions can cause facial pain. Treatment options include medicines, surgery, and complementary techniques.

Not medical advice.
Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
