Prevalence of PD-L1 Expression in Patients With Advanced Urothelial Carcinoma
A Prospective, Non-Interventional Study to Assess the Prevalence of PD-L1 Expression in the First-Line Setting of Locally Advanced/Unresectable or Metastatic Urothelial Carcinoma
The purpose of this study is to assess the prevalence of pre-treatment tumor tissue PD-L1 expression in patients diagnosed with advanced urothelial carcinoma.
Advanced urothelial carcinoma (UC) (locally advanced/unresectable or metastatic UC) is a fatal disease with 5-year survival rate of 5%. The most frequently studied diagnostic for advanced UC is the programmed death-ligand 1 (PD-L1) protein expression in tumor tissue. A better understanding of PD-L1 expression in a "real world" setting could help understand its clinical utility in the management and decision making in advanced UC and clinical trial design
Categorization of PD-L1 results (dichotomous, high vs. low) based on pre-treatment tissue samples.
To assess the association of pre-treatment tumor tissue PD-L1 expression with pre-treatment tumor tissue TMB (tTMB) based on the chosen assay
Study Arms / Comparison Groups

Description: Patients with a confirmed diagnosis of advanced urothelial carcinoma, prior to or during first line therapy, who have available tumor tissue samples collected as part of standard of care
* Includes publications given by the data provider as well as publications identified by National Clinical Trials Identifier (NCT ID) in Medline.

Inclusion Criteria: - Provision of written informed consent - Age ≥18 years old - Patient must have advanced UC confirmed by their HCP; histologically- confirmed diagnosis of UC an dHCP-confirmed advanced UC. - Patient must be either currently receiving 1L systemic treatment for their advanced UC or will be starting 1L systemic treatment (i.e. "newly diagnosed" advanced UC; 1L therapy is defined as the first systemic therapy given for advanced UC). - Patient remains eligible for the study if they received neoadjuvant or adjuvant platinum-based chemotherapy if their recurrence was more than 12 months after their last chemotherapy dose. - Radio-sensitizing chemotherapy as part of chemoradiation is NOT counted as neoadjuvant or adjuvant chemotherapy; thus, the 12-month interval mention above does not apply, and the patient would be eligible - Patients with available tumor tissue sample (fresh or archival - up to 3 years old) that was collected as part of SoC any time prior to 1L treatment for advanced UC with a target of 18 slides (7 minimum) available for biomarker testing (PD-L1 and tTMB). Already prepared slides must have been cut within 6 months prior to PD-L1 testing. Exclusion Criteria: - Patients concurrently enrolled in other clinical trials that prohibit their participation in a non-interventional study - Patient has resectable localized UC and has refused surgery - Patients with history of non-urothelial active malignancy that completed therapy within 2 years from study enrollment except: - Any resected in situ carcinoma or non-melanoma skin cancer - Localized (early stage) cancer treated with curative intent (without evidence of recurrence and intent for further therapy) and in which no systemic therapy was indicated
