Abstract
Aim: To compare the overall survival of patients with metastatic urothelial carcinoma (mUC) who failed platinum-based chemotherapy and received durvalumab or chemotherapy. Patients & methods: In an indirect comparison of patients with mUC who failed platinum-based chemotherapy, those who received durvalumab in a single-arm study were matched to patients from the Flatiron oncology electronic medical record database who received chemotherapy (n = 158 for each cohort). Matching was based on propensity scores. Kaplan-Meier methods and Cox regression models were utilized. Results: Median overall survival was 11.2 months (95% CI: 7.2-16.9) for durvalumab versus 8.2 months (95% CI: 6.7-9.8) for chemotherapy (hazard ratio: 0.63; 95% CI: 0.48-0.84). Conclusion: As a second-line therapy for mUC, durvalumab was associated with longer overall survival than chemotherapy.
