Evaluating the Impact of 18F-FDG-PET-CT on Risk Stratification and Treatment Adaptation for Patients with Muscle Invasive Bladder Cancer (EFFORT-MIBC)

January 13, 2025 updated by: University Hospital, Ghent

Evaluating the Impact of 18F-FDG-PET-CT on Risk Stratification and Treatment Adaptation for Patients with Muscle Invasive Bladder Cancer (EFFORT-MIBC): a Phase II Prospective Trial

Evaluate the impact of 18F-FDG-PET-CT on the staging of patients with muscle invasive bladder cancer. Based on the results of 2 18F-FDG-PET-CT's patients are stratified in non-metastatic, oligometastatic and polymetastatic bladder cancer patients and the treatment is adapted accordingly to improve overall survival.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Active Comparator: Non-metastatic MIBC
No signs of extra-pelvic metastasis on conventional imaging (abdominopelvic and thoracic CT/MRI) and 18F-FDG-PET-CT's
Procedure: Standard of care
Patient receives standard of care therapy with either radical cystectomy with pelvic lymph node dissection or trimodality therapy (consisting of a visible complete TURb and radio chemotherapy). Afterwards regular follow up is performed.
Experimental: Oligo-metastatic MIBC on 18F-FDG-PET-CT
No signs of extra-pelvic metastasis on conventional imaging (abdominopelvic and thoracic CT/MRI) but presence of ≤ 3 metastasis on 1 or both 18F FDG PET-CT 's
Radiation: Metastasis directed therapy (MDT)

Experimental: Poly-metastatic MIBC on 18F-FDG-PET-CT

Drug: Immunotherapy
Patient receives standard of care therapy with either radical cystectomy with pelvic lymph node dissection or trimodality therapy (consisting of a visible complete TURb and radio chemotherapy). Afterwards immunotherapy will be initiated and regular follow up will be performed.

What is the study measuring?
