Study summary

MIBC-PET is a prospective, monocentric, no-profit study with paired imaging comparison enrolling 60 patients with newly diagnosed, histologically confirmed high-grade MIBC. All patients undergo baseline staging with [18F]FDG PET/CT and contrast-enhanced CT (ceCT) of chest, abdomen, and pelvis. A second [18F]FDG PET/CT and CT are performed after two cycles of neoadjuvant therapy. [18F]FDG PET/CT includes both standard delayed imaging and an early dynamic pelvic acquisition to overcome urinary tracer interference. The primary endpoints are (1) diagnostic accuracy of [18F]FDG PET/CT versus ceCT for baseline staging, and (2) accuracy of [18F]FDG PET/CT in predicting pathological response to neoadjuvant chemotherapy. Secondary endpoints include validation of early dynamic [18F]FDG PET/CT for local staging and radiomic/AI-based predictive modeling.

Study population

adults aged 18 years or older with a histologically confirmed diagnosis of high-grade MIBC

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

  • Adults aged 18 years or older Previously known oncological disease confirmed diagnosis of high-grade MIBC Non-muscle-invasive, or low-grade bladder cancer

Eligible for platinum-based treatment on clinical evaluation:

  • performance status of 0-1,
  • of at least 60 mL/min,
  • absence of comorbidities that would contraindicate chemotherapy (such as grade ≥2 neuropathy, grade ≥2 hearing impairment, or significant cardiopathy) Impossibility to perform imaging procedures, including
  • Claustrophobia
  • history of iodinated contrast medium allergy precluding ceCT
  • diabetes uncontrolled by medications Sign of

Terms in these criteria, in plain language(5)

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

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.

What researchers measure

Primary outcomes

  1. Baseline Diagnostic Accuracy of [18F]FDG PET/CT in MIBC

    Assessment of \[18F\]FDG PET/CT for initial staging of newly diagnosed muscle-invasive bladder cancer, compared with thoraco-abdomino-pelvic contrast-enhanced CT (gold standard) to determine diagnostic accuracy in defining disease extent.

    Time frame: At baseline, prior to initiation of neoadjuvant therapy (each cycle has a duration of 21 days)

  2. Interim [18F]FDG PET/CT Prediction of Pathological Response

    Evaluation of the ability of interim \[18F\]FDG PET/CT to predict pathological response to neoadjuvant treatment, assessing its potential role in guiding therapeutic decision-making.

    Time frame: After 2 cycles of neoadjuvant therapy, prior to surgery (each cycle has a duration of 21 days)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2024 (actual). Primary completion is estimated for Dec 2026, 32 months after the start.

Of 167 non-industry observational studies under Urinary Bladder Neoplasms, half reached primary completion within 60 months of starting (the median), counting those still running; a quarter within 30. This study's planned 32 months is below that.

Counting every sponsor, half of 202 studies reached it within 60 months; a quarter within 32.

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 Aug 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
