Abstract

Background: Durvalumab has shown meaningful clinical activity in patients with metastatic urothelial carcinoma (mUC) in Study 1108 (NCT01693562). An important focus in treatment is health-related quality of life (HRQOL). Here, patient-reported outcomes (PROs) from Study 1108 and their relationship with inflammatory biomarkers are explored.

Methods: Disease-related symptoms, functioning, and HRQOL were assessed with the Functional Assessment of Cancer Therapy-Bladder (FACT-Bl) and the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30). Relationships between PRO improvements and the best changes in the tumor size, albumin level, and neutrophil-lymphocyte ratio (NLR) were assessed with Spearman correlation analysis.

Results: The mean FACT-Bl total score improved from 107.5 (standard deviation [SD], 23.0) at the baseline to 115.4 (SD, 22.6) on day 113, with similar increases found for the Trial Outcome Index (TOI) and Bladder Cancer Subscale (BLCS) scores. The mean FACT-Bl total scores improved over time, and the FACT-Bl TOI scores significantly improved by day 113 (P < .05). The mean EORTC QLQ-C30 Global Health Status/Quality of Life score improved from 57.1 (SD, 24.8) at the baseline to 69.0 (SD, 21.4) on day 113; the functional scale and symptom scores (day 113) were higher than the baseline scores (P < .05) for EORTC Social Functioning. The FACT-Bl total, BLCS, and TOI scores improved in 32.6%, 34.9%, and 32.6% of the patients by day 113; 26.3% to 37.8% of the patients exhibited improvements in EORTC QLQ-C30 functional scores. The best tumor shrinkage and posttreatment improvements in serum albumin and NLR correlated with increases in FACT-Bl total, TOI, and BLCS scores and in EORTC Physical Functioning and Role Functioning scores (P < .05).

Conclusions: Durvalumab was associated with improvements in disease-related symptoms, functioning, and HRQOL in patients with mUC. Improvements in systemic inflammation may contribute to PRO improvements in these patients.
