Study summary

This is an investigator initiated study to test the efficacy of an upright MRI (Magnetic Resonance Imaging) for the screening of prostate cancer. The purpose of this study is to compare Upright MRI as a technique to PSA (Prostate Specific Antigen) and current MRI imaging. It will take place at Mount Sinai Hospital, and last for a total of about 5 years. Eligible patients will be determined by the urologist. The target population is men who are at risk for prostate cancer, as determined by the urologist. Diagnostic criteria will include elevated PSA and an abnormal digital rectal exam (DRE). After patients are screened and determined eligible, they will be asked to have a seated MRI using the Indomitable Magnetic Resonance Imaging Scanner, Ex vivo magnetic resonance imaging using 0.6 T strength, as well as a standard of care closed 3T MRI. After each scan, the patient will be given a series of questionnaires to assess their comfort level during the scan. Patients will be followed every 6 months after completion of (or early withdrawal from) study enrollment until 5 years.

Read the detailed description

Prostate cancer (PCa) is the second most common cancer among men in the United States, with over 180,000 new cases diagnosed in 2016. This commonality implies that set standards need to be set and devise effective tools to screen and diagnose prostate cancer. Today, prostate specific antigen (PSA) test is the most widely adopted screening method for PCa. Since its introduction in 1979, it has helped in earlier diagnosis of PCa and has had a marked shift on the stage at which PCa is identified. PSA, although popular as a screening tool, has several shortcomings. It is organ-specific rather than cancer-specific, which means that its values can be elevated even for non-malignant conditions . Indeed, PSA based screening has reported positive predictive value as low as 30% (PSA cutoff >4.0 ng/dL) for detecting prostate cancer and an over diagnosis rate of 50%, which leads to unnecessary biopsies and aggressive treatments of men with clinically indolent (insignificant) disease.

Current diagnostic pathway of prostate cancer requires men with elevated PSA and abnormal Digital Rectal exam to undergo a Trans Rectal Ultra Sound (TRUS) guided biopsy. TRUS is a blind-systematic biopsy, which randomly samples prostate tissue. This can lead to missing or under-diagnosing clinically significant cancer and over-diagnosing clinically insignificant disease. TRUS biopsy is itself associated with morbidity, mainly in the form of hematuria, hematospermia, pain, urinary retention and sometimes can cause life-threatening sepsis.

Many of the PSA screened detected prostate cancers detected on TRUS are clinically insignificant and even if left untreated have little to no clinical impact on an individual's remaining life. Overtreatment resulting from over diagnosis often leads to side effects like erectile dysfunction (approx. 60%) from radical therapy and urinary incontinence.

Study population

Men at risk for prostate cancer

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Men at risk of prostate cancer and have been advised to have a prostate MRI.
  • Age ≥ 18 years.
  • Fit for undergoing all study protocol procedures which includes an ultrasound guided .
  • Able to tolerate general or spinal anesthesia.
  • Ability to understand and the willingness to sign a written and to comply with the protocol.

Exclusion criteria

Exclusion Criteria:

  • Patients who have been treated using 5- alpha-reductase inhibitors at the time of study enrollment or 6 months prior to enrollment.
  • Patients with previous history of prostate , prostate surgery or treatment for prostate cancer (interventions for benign prostatic hyperplasia/bladder outflow obstruction is acceptable)
  • Patients who have evidence of a urinary tract infection or history of acute prostatitis within the last 3 months.
  • Patients to undergoing the MRI procedure e.g. pacemaker, estimated \<=50, automatic implantable cardiac defibrillators.
  • History of any other medical condition precluding procedures described in the protocol
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Started Oct 2018 (actual). Primary completion is estimated for Jul 2026, 93 months after the start.

Of 541 non-industry observational studies under Prostatic Neoplasms, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 162. This study's planned 93 months is above that.

Counting every sponsor, half of 650 studies reached it within 60 months; a quarter within 29 and three quarters within 141.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 7, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
