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 Results may not be published yet.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.

Summary

This study tests a new low-cost device designed to help people who developed lockjaw (trismus) after radiation treatment for head and neck cancer. The device is a non-invasive jaw stretcher with sensors that measure pressure and how wide the mouth opens, giving real-time feedback. Researchers hope it will improve mouth opening, eating, speech, and quality of life in 35 participants over 6 weeks.

What this could mean

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

Active substance
Trismus Device Prototype (non-invasive jaw-stretching device with sensors)
What this could lead to
If it works, this could provide an affordable, sensor-guided exercise device to help head and neck cancer survivors regain mouth opening and improve eating, speech, and oral hygiene.
What could go wrong
This is a small early-stage trial with only 35 participants and no control group, so results may not apply broadly. The device may not significantly improve mouth opening or could cause discomfort.

Expected to finish

Mar 2028

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.

Not accepted

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

Show the full entry requirements

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

Inclusion Criteria: * Male or female \>= 18 years of age at visit 1. * Documentation of a radiation-induced trismus diagnosis as evidenced by one or more clinical features consistent with the trismus phenotype (maximum interincisal opening (MIO) \< 35 mm) and a history of head and neck radiation * Written informed consent (and assent when applicable) obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study. Exclusion Criteria: * Presence of a condition or abnormality that in the opinion of the investigator would compromise the safety of the patient or the quality of the data. * Minors (age \< 18 years) or patients with inability to provide informed consent.
