NCT ID NCT04349501

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 Results may not be published yet.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

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

Summary

This study looks at whether a special type of MRI, called RSI-MRI, can predict how well prostate cancer responds to radiation and hormone therapy. About 100 men with high-risk, localized prostate cancer will get this MRI before and during treatment. The goal is to see if the scan can identify who might have their cancer come back within three years.

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

About 100 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2020

Expected to finish

Dec 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 years and older

Sex

Male participants only

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: * Male, aged ≥18 years, with histologically confirmed adenocarcinoma of the prostate * High-risk prostate cancer (any of: PSA ≥20 ng/mL or cT3-T4 stage or Gleason score ≥8) * Intended treatment and follow-up according to standard of care for prostate cancer * Planning to undergo definitive radiotherapy with neoadjuvant and concurrent androgen deprivation therapy * In good general health as evidenced by medical history and Eastern Cooperative Oncology Group (ECOG) performance status 0-2 * Provision of signed and dated informed consent form * Stated willingness to comply with all study procedures and availability for the duration of the study Exclusion Criteria: * Prior radiotherapy to the pelvis * Prior treatment for prostate cancer (cryotherapy, high frequency focused ultrasound, prostatectomy) * Hip prosthesis * Contraindication to MRI, per institutional requirements * Technetium-99 bone scan showing no clear evidence of distant metastasis * MRI or CT scan of the pelvis showing no clear evidence of bone or distant metastasis * Another malignancy, unless in remission or unlikely to impact the patient's survival or ability to receive standard care for prostate cancer (e.g., cutaneous basal cell carcinoma) * Patient has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
