Abstract
BACKGROUND: Generalizability of registrative clinical trials to real-world clinical practice is influenced by comparability of patients in the two settings. We compared characteristics of cancer patients in registrative trials with real-world clinical practice in Italy. METHODS: Data on age, sex and performance status (PS) were derived from web-based monitoring registries developed by Italian Medicines Agency (AIFA) and corresponding registrative trials reported in the European Public Assessment Reports (EPAR) of European Medicines Agency (EMA). Weighted means were calculated in registries and trials and differences were described. Multivariate analysis was performed using Principal Component Analysis and Cluster Analysis. FINDINGS: From January, 2013 to April, 2023, 419,461 unique pairs of patients and therapeutic indications were recorded in 129 AIFA registries. Within 140 related trials, 87,452 patients had been enrolled. Median age and rate of elderly (?65 years old) patients were higher in monitoring registries than in clinical trials [mean difference of median age 5.3 years, p < 0.001; mean difference of elderly rate 17.17% (95% CI 1.06, 1.48)]. Overall, rate of female patients was not different between registries and trials [mean difference -0.55% (95% CI -1.06, -0.05)]. Mean rate of patients with deteriorated PS was low both in trials (3.1%) and in registries (4.3%) with a mean difference of 1.27% (95% CI 1.06, 1.48). Two clusters were identified with multivariate analysis: one including more registries (higher median age and elderly rate, lower female rate, higher rate of deteriorated patients), the other more trials (lower median age and elderly rate, higher female rate, lower rate of deteriorated patients). INTERPRETATION: This study supports that cancer patients enrolled in trials do only partially represent those who have been treated in Italy in clinical practice. Inclusiveness of registrative trials should be increased to ensure generalizability of results to real-world population. FUNDING: Partially supported by Italian Ministry of Health.
