National registry for patients with advanced kidney and bladder cancer
Official title: Clinical Research Platform On Urologic Cancer Treatment And Outcome (Registry Platform Urologic Cancer; CARAT)
Run by iOMEDICO AG · NCT03374267 · Data updated 2026-11-12
This study is setting up a national registry to track the experiences and treatments of patients with advanced kidney and bladder cancer over a few years to help improve care and research in the future.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adult patients with locally advanced, inoperable, or metastatic renal cell carcinoma or urothelial carcinoma who are starting their first-line systemic treatment.
✕Probably not a fit
Patients with early-stage or operable renal cell carcinoma or urothelial carcinoma may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This project aims to establish a national, prospective, longitudinal cohort study in Germany to document uniform data on the characteristics, molecular diagnostics, treatments, and disease progression of patients with advanced renal cell carcinoma and urothelial cancer. The registry will follow patients for up to three years for renal cancer and two years for bladder cancer, collecting comprehensive data on treatments, outcomes, and patient-reported quality of life. It will also create a decentralized biobank to support future research in these cancers.
Why it matters
Potential benefit: If successful, this registry could enhance understanding of treatment patterns and improve patient outcomes for those with advanced renal cell carcinoma and urothelial cancer.
How similar studies have gone: Other observational studies have successfully established cancer registries, indicating that this approach has potential for meaningful contributions to cancer treatment understanding.

Mixed histologies are allowed (main component must be urothelial histology, with minor variants accepted). * Age ≥ 18 years at the time of diagnosis. * Written informed consent within 15 weeks from diagnosis of MIBC. Exclusion Criteria: Cohorts aRCC and aUBC (prospective) * Patients with prior systemic therapy for aRCC or aUBC * No systemic treatment for aRCC or aUBC Cohort High-risk MIUC (prospective and retrospective) * Partial cystectomy or partial nephrectomy of the primary tumor as definitive therapy * Metastatic disease (M1) at the time of surgery Cohort MIBC (prospective) * Clinically detectable metastases (M1) at the time of diagnosis. * Treatment in palliative intention (for tumors considered inoperable).
