For patients with locally advanced/metastatic urothelial carcinoma (la/mUC), first-line (1L) treatment with platinum-based chemotherapy (PBC) followed by avelumab 1L maintenance (1LM) is a recommended therapy per treatment guidelines in patients without disease progression. However, contemporary real-world (rw) data among patients receiving this treatment are necessary to understand clinical outcomes and optimal treatment sequencing. This retrospective cohort study analyzed rw treatment patterns and clinical outcomes, including overall survival (rwOS) and progression-free survival (rwPFS), in patients with la/mUC receiving avelumab 1LM. From the Flatiron Health database, 214 patients who received avelumab 1LM following 1L PBC were included. From the start of avelumab 1LM, median rwOS was 23.8 months (95% CI: 18.2—not estimable [NE]) and median rwPFS was 5.1 months (95% CI: 4.1–7.0). A total of 96 patients received second-line (2L) therapy, with 53 receiving enfortumab vedotin (EV). From the start of 2L EV, median rwOS was 11.2 months (95% CI: 6.8—NE) and median rwPFS was 4.9 months (95% CI: 3.9–8.8). Treatment patterns and clinical outcomes in this study align with guidelines and outcomes observed in the JAVELIN Bladder 100 and EV-301 clinical trials and other rw studies, supporting the use of 1L PBC followed by avelumab 1LM and 2L EV for eligible patients.

Objective: To identify the relationship between resource utilization and treatment of asthma in subjects who were first time users of controller therapies, either fluticasone propionate (FP) and salmeterol delivered in a single Diskus device (FSC) or FP monotherapy.Methods: A retrospective, observational cohort analysis evaluated pharmacy and medical claims from subjects from a commercial managed-care database, which is similar in makeup to the US privately insured population, with a diagnosis of asthma and ≥1 prescription for FSC or FP dispensed from 1/1/2001 to 4/30/2005. Outcomes of interest were asthma-related emergency department (ED) visits, inpatient (IP) visits, and a combined outcome (IP or ED visits). Predicted rates of asthma-related and all-cause intubations were also reported for each cohort. Multivariate analysis of events was conducted using logistic regression and Cox proportional hazard regression. All outcomes were adjusted for differences in baseline characteristics.Results: There were 58 270 subjects identified (FSC, n = 42 466; FP, n = 15 804). Mean age was 37.65 years and 35.75% was female. The use of FSC was associated with lower risk of having an asthma-related ED visit (adjusted OR 0.79; 95% CI, 0.72-0.87) and an asthma-related ED/IP visit (OR 0.80; 95% CI, 0.73-0.88). Asthma-related ED and ED/IP rates were also significantly lower for FSC than for FP. There were no differences observed in post-index asthma-related intubations rates.Conclusion: In this observational study using a large managed-care database, subjects treated with FSC were at significantly less risk for developing serious asthma exacerbations and had lower resource utilization than a cohort of subjects treated with FP. This is clinically meaningful despite the inherent limitations of these types of observational studies. [ABSTRACT FROM AUTHOR]
