Observational Study Protocol: LIVER-R

Summary

Given the number of anticipated durvalumab-based treatment launches in the hepatobiliary cancer space over the next 3 years, there is a need to capture contemporary real-world data across these indications. LIVER-R is a multi-country, multi-center, observational study of patients with a confirmed diagnosis of hepatobiliary cancer treated with or without a durvalumab-based regimen as part of routine clinical practice or early access program (EAP). The study design will include primary and secondary data collection. The primary objective of this study is to evaluate the effectiveness of regimens (durvalumab-based or otherwise) in real-world settings as measured by real-world overall survival. Other endpoints include demographics, clinical characteristics, clinically significant events of interest, treatment patterns, concomitant medications, treatment provider characteristics, and other real-world clinical endpoints (such as duration of treatment, progression-free survival, time to treatment progression, time to next treatment, time to treatment discontinuation, recurrence-free survival, and time to treatment recurrence).
