What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether a special low-field MRI scanner can give clearer images for prostate cancer radiation therapy in people who have both hips replaced. Standard MRI often creates blurry images around metal implants, making it hard to aim the radiation precisely. The researchers will test a system where patients are scanned in a low-field MRI and then moved to a radiation machine without changing position, hoping to improve treatment accuracy and reduce side effects. About 13 adults with localized prostate cancer and bilateral hip prostheses will take part.

Inclusion Criteria: * Diagnosis of localized prostate cancer suitable for definitive SBRT based on a multidisciplinary tumour board recommendation and / or clinical practice guideline. * Presence of bilateral hip prostheses labeled as MR safe or MR-conditional. * ECOG performance status ≤ 2. * Signed informed consent. * Age ≥18 years - Exclusion Criteria: * Large body size that would not fit into the MRI-simulator bore * Hip prosthesis that are labeled as MR unsafe; * Contraindications to MRI including but not limited to: * Claustrophobia unmanageable by sedation * Electronic devices such as pacemakers, defibrillators, deep brain stimulators, cochlear implants that are labeled as MR unsafe, electronic devices labeled as MR safe or MR conditional are not a contraindication; * Metallic foreign body in the eye or aneurysm clips in the brain; * Clinically significant concomitant diseases that would interfere with the study (e.g. hepatic dysfunction, cardiovascular disease). * Inability to follow the procedures of the study, e.g. due to language problems, psychological disorders, dementia, etc. * Enrolment of the investigator, his/her family members, employees and other dependent persons.
