About this study

Official title: Investigation of Prognostic Biomarkers in Patients With Urothelial Carcinoma Treated With Platinum Regimens

Bladder cancer (BC) is a heterogeneous malignancy with dismal outcome.Despite treatment, the 5-year overall survival rates for MIBC are <50%, with many patients unresponsive or inapt, necessitating biomarkers to select those most likely to respond or fit for treatment

Read the detailed description

In this study was assessed the associations among most frequently mutated genes and with clinicopathological features, as well as the prognostic significance of the presence of mutations in the top mutated and DNA Damage response (DDR) mutated genes in terms of Overall Survival (OS). Moreover, overall tumor-infiltrating lymphocytes (TILs) density was measured, analyzed immunohistochemically the expression of PD-L1, the four MMR proteins (MLH1, MSH2, MSH6 and PMS2) and tumor or stromal CD8+ cytotoxic T lymphocyte infiltrates and assessed their association with each other, top mutated genes and available clinicopathological parameters together with their role in prognosis.

Questions about this trial

What is this clinical trial studying?

An observational study of Bladder Cancer, run by Hellenic Cooperative Oncology Group.

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 3 inclusion and 1 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: finished, as of the sponsor's last update on 4 May 2021. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of mutational profile in patients with urothelial carcinoma (time frame: Up to 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04872036, which also lists 66 linked publications.

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 4 May 2021.
