What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a precise radiation treatment for trigeminal neuralgia, a condition that causes severe facial pain. Instead of a metal frame screwed into the skull, a special face mask holds the head still while x-rays target the painful nerve. The trial includes 40 adults whose pain isn't controlled by medication. Researchers want to see if this frameless approach is feasible and how well it relieves pain.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Virtual cone radiosurgery device (frameless face mask)
What this could lead to
If it works, this could offer a non-invasive, precise treatment option for people with severe facial nerve pain that isn't helped by medication.
What could go wrong
This is a small, early-phase trial with only 40 people at one hospital. The device may not relieve pain for everyone, and there are risks of nerve damage or other side effects.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

40 people

The number who actually took part.

Started

Nov 2015

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 99 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with trigeminal neuralgia pain that is not well controlled despite medical management (BNI 4 OR BNI 5) * Patients must have an ECOG status of 0, 1, or 2 * Patients must be at least 18 years of age * Life expectancy must be greater than 12 months * MRI of brain within prior 12 months to confirm lack of other causes of facial pain * All patients must be given written informed consent Exclusion Criteria: * Patients who have had prior brain radiosurgery or therapeutic radiation therapy to the pons * Patients with atypical trigeminal neuralgia or headache pain syndromes * Patients with pain associated with multiple sclerosis or base of skull tumor * Patients with medical contra-indications to MR imaging (e.g. pacemaker)
