Observational Study Protocol: LIVER-R

AstraZeneca4,490 enrolled

Overview

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 multicountry, multicenter, observational study of patients with a confirmed diagnosis of hepatobiliary cancer treated with 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 durvalumab-based regimens 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, and other real-world clinical endpoints (such as duration of treatment, progression-free survival, time to treatment progression, time to next treatment, recurrence-free survival, and time to treatment recurrence).

LIVER-R is a real-world, multi-country, multi-centre study aiming to enroll approximately 2500 pts with unresectable hepatocellular carcinoma (uHCC; n=1135) or advanced biliary tract cancers (aBTCs; n=1355) across 22 countries from North and South America, Europe, the Middle East and the Asia-Pacific region. The study design will include primary and secondary data collection. Primary data will be collected in real-time during the patient's routine visit. Secondary data will be collected from the patient's medical record at enrollment and at prespecified study time points (6-month intervals). The study population includes adult patients whose physician has previously made the decision to treat them with a durvalumab-based regimen for hepatobiliary cancer as part of routine clinical practice or patients receiving treatment through EAP. The study will include a baseline period of up to 5 years before the index date (initiation of a Durvalumab-based regimen) and a follow-up period to the earliest of death, loss to follow-up, withdrawal, or end of study for a maximum follow-up of 2 years for patients with aBTCs or 3 years for patients with uHCC. This is a descriptive, noncomparative study. No formal hypotheses are to be tested. All descriptive analyses will be conducted separately for each primary hepatobiliary cancer indication. Kaplan Meier estimates will be produced for time-to-event outcomes.

Outcomes

Primary Outcomes

Real-world overall survival (rwOS)

rwOS will be calculated as the time from the index date to date of death, by any cause.

Time frame: rwOS will be assessed as OS rates at 6, 12, 24 months (both aBTC and uHCC), and 36 months (uHCC), median OS for a maximum follow-up of 2 and 3 years for aBTC and uHCC, respectively.

Secondary Outcomes

Real-world duration of treatment (rwDOT)

rwDOT will be calculated for each systemic treatment as the time from the index date to date of discontinuation for any reason.

Time frame: rwDOT will be assessed as median DOT for a maximum follow-up of 2 years (aBTC) or 3 years (uHCC).

Real-world progression free survival (rwPFS)

rwPFS will be calculated as the time from the index date to the date of documented disease progression as determined by the physician's assessment or death, whichever is earlier.

Time frame: rwPFS will be assessed as PFS rates at 6, 12, 24 months (both aBTC and uHCC), and 36 months (uHCC), median PFS for a maximum follow-up of 2 and 3 years for aBTC and uHCC, respectively.

Real-world time to progression (rwTTP)

rwTTP will be calculated as the time from the index date to the date of documented disease progression as determined by the physician's assessment.

Time frame: rwTTP will be assessed as median TTP for a maximum follow-up of 2 years (aBTC) or 3 years (uHCC).

Real-world time to next treatment (rwTTNT)

rwTTNT will be calculated as the time from the index date to the date of initiation of the next treatment.

Time frame: rwTTNT will be assessed as median TTNT for a maximum follow-up of 2 years (aBTC) or 3 years (uHCC).

Real-world recurrence free survival (rwRFS)

rwRFS will be defined as the time from the index date to the date of documented disease recurrence as determined by the physician's assessment or death, whichever is earlier. The analysis will be performed in patients who underwent curative therapy (resection or ablation).

Time frame: rwRFS will be assessed as RFS rates at 6, 12, 24 months (both aBTC and uHCC), and 36 months (uHCC), median RFS for a maximum follow-up of 2 and 3 years for aBTC and uHCC, respectively.

Real-world time to recurrence (rwTTR)

rwTTR will be defined as the time from the index date to the date of documented disease recurrence as determined by the physician's assessment. The analysis will be performed in patients who underwent curative therapy (resection or ablation).

Time frame: rwTTR will be assessed as median TTR for a maximum follow-up of 2 years (aBTC) or 3 years (uHCC).

Patient demographic and clinical characteristics

Descriptive statistics will be used to describe demographic and clinical characteristics for the enrolled patients.

Time frame: Patient demographic and clinical characteristics will be captured up to 5 years prior to the index date.

Percentage of patients receiving each treatment regimen

Treatment patterns will be calculated from the index date until death, loss to follow-up, withdrawal from the study, or end of the study, whichever is earliest.

Time frame: Treatment patterns will be captured from the index date until the earliest of death, loss to follow-up, withdrawal, or end of study for a maximum follow-up of 2 years for patients with aBTCs or 3 years for patients with uHCC.

Clinically significant events (CSEs) of interest leading to a medical intervention

CSEs of interest leading to medical intervention including durvalumab based treatment interruption, discontinuation, hospitalization, or which require interventions of concomitant use of corticosteroids, immunosuppressants and/or endocrine therapies will be captured for the enrolled patients.

Time frame: CSEs will be captured from the index date through 90 days after the last administration of durvalumab-based regimen or death, whichever occurs first.
