About this study

Official title: Virtual Histology of the Bladder Wall for Bladder Cancer Staging; A Novel Intravesical Contrast-Enhanced MRI for Bladder Cancer Staging

This is a phase Ib study of the safety and performance of a novel intravesical contrast-enhanced Magnetic Resonance Imaging protocol for determination of bladder cancer stage prior to transurethral resection of bladder tumor (21 subjects) or prior to radical cystectomy for muscle invasive disease (21 subjects). Subjects will undergo a single MRI study: a pre-contrast, single breath hold image followed by sterile placement of a temporary urethral catheter for instillation of a 50mL solution containing Gadobutrol (4 mM) plus ferumoxytol (5 mM) and then a second, post-contrast image. Images will be reviewed by two dedicated abdominal radiologists, who are blinded to the pathologic staging, for determination of tumor presence and depth of bladder wall penetration.

Read the detailed description

Twenty one patients with at least one cystoscopically confirmed papillary bladder tumor, who have been scheduled for Transurethral Resection of Bladder Tumor (TURBT) for surgical extirpation and staging, and twenty-one patients with histologically confirmed, muscle invasive transitional cell carcinoma of the bladder who have been scheduled for definitive radical cystectomy with curative intent will be recruited for a single study Magnetic Resonance Imaging to be performed between 1 and 6 days prior to their scheduled procedure.

Magnetic Resonance Imaging of all the enrolled patients will be performed on a 60-cm, wide-bore, 3T scanner (Siemens AG, Erlangen, Germany) with a 32-channel pelvic phased-array coil placed over the bladder using radial k-space sampling technique for volumetric free breathing acquisition with NCM enhanced StarVIBE57. Un-enhanced fast spoiled gradient-echo images with fat suppression will be obtained prior aseptic instillation of 50cc of a novel contrast mixture (NCM) of Gadobutrol (4 mM) plus Ferumoxytol (5 mM) in sterile water through a temporary urethral catheter. The catheter will then be removed and the patient repositioned in the scanner to obtain post-contrast images. All the image datasets will be linearly registered to the subject to ensure that regions of interest represent the same anatomical location at all time points. Post-contrast T1, pre-contrast T1 and deltaT1 will be measured from the acquired images. Two radiologists blinded to the pathologic findings will evaluate the Magnetic Resonance images to assign a radiologic tumor stage that will be compared with the subsequent pathologic stage determined at time of surgery. Following the MRI study, subjects will proceed with their surgical procedure as scheduled per standard of care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Magnetic Resonance ImagingDiagnostic test

    60-cm wide bore 3T scanner (Siemens AG, Erlangen, Germany) with a 32-channel pelvic phased-array coil placed over the bladder.

  • Gadobutrol intravesical administration (4mM)Drug

    Also called Image result for other names for Gadobutrol Gadavist

    A paramagnetic macrocyclic gadolinium-based contrast agent administered intravenously for use in magnetic resonance imaging. Contrast-enhancement is a result of the neutral complex of gadolinium and dihydroxy-hydroxymethylpropyl- tetraazacyclododecane-triacetic acid (butrol).

  • Ferumoxytol intravesical administration (5 mM)Drug

    Also called FERAHEME

    An iron preparation (Fe3O4) approved for intravenous treatment of anemia in the setting of renal failure, comprised of superparamagnetic iron oxide nanoparticles which are coated by a semi-synthetic carbohydrate shell in an isotonic, neutral pH solution.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Accuracy of Magnetic Resonance Imaging assessment of depth of bladder wall penetration to predict pathologic stage determined at tumor resection

    The assessment of clinical tumor stage assigned by the radiologist will be compared to the stage reported by the clinical pathologist following tumor resection to determine the overall accuracy of MRI for bladder cancer staging.

    Measured: 4 weeks

Secondary outcomes (2)
  1. Accuracy of Magnetic Resonance Imaging to detect residual/recurrent bladder tumor

    Patients are typically scheduled for radical cystectomy after initial TURBT with or without neoadjuvant chemotherapy. MRI findings of bladder tumor will be compared with the areas of tumor identified on whole mount sectioning of the bladder to estimate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MRI for bladder cancer. Receiver operating characteristic (ROC) curve analysis will be used to estimate the tumor size threshold value for the diagnosis with MRI.

    Measured: 4 weeks

  2. Rate of Adverse Events

    Characterize the safety profile of MRI imaging following direct bladder instillation of a mixture of Gadobutrol and Ferumoxytrol (50mL in sterile water) via urethral catheter by soliciting and recording adverse events while on study.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Magnetic Resonance Imaging, Gadobutrol intravesical administration (4mM) and Ferumoxytol intravesical administration (5 mM) in people with Urinary Bladder Neoplasms, run by Jodi Maranchie at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 17 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Brieanna Marino, MS ((412) 647-8258, rowlesbm@upmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Accuracy of Magnetic Resonance Imaging assessment of depth of bladder wall penetration to predict pathologic stage determined at tumor resection (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2025.
