About this trial
The purpose of this study is to measure the efficacy and safety of rilvegostomig with gemcitabine plus cisplatin vs. durvalumab with gemcitabine plus cisplatin as first line treatment for patients with advanced BTC.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Histologically confirmed adenocarcinoma of the biliary tract, including intra-hepatic or extra-hepatic cholangiocarcinoma (CCA) and gallbladder carcinoma (GBC).
Unresectable locally advanced or metastatic BTC, previously untreated in the advanced disease setting
Known PD-L1 status assessed at a central laboratory using an acceptable tumor sample.
Measurable disease by RECIST 1.1 criteria using CT or MRI and is suitable for accurate repeated measurements.
Disqualifiers
Ampullary carcinoma
Any prior systemic therapy received for unresectable, locally advanced or metastatic BTC.
Any prior exposure to any other therapy targeting immune-regulatory receptors or mechanisms.
Any concurrent chemotherapy, radiotherapy, immunotherapy, investigational, biologic, or hormonal therapy for cancer treatment other than those under investigation in this study.

Treatment groups
Trial outcomes
Primary outcomes
Overall Survival (OS) in the PDL1 ≥ 1% population
Overall Survival is defined as time from randomization until the date of death due to any cause.
Secondary outcomes
Overall Survival in the intent to treat (ITT) population
Overall Survival is defined as time from randomization until the date of death due to any cause.
Progression Free Survival (PFS) in the PDL1 ≥ 1% population
PFS is defined as the time from randomization until radiological progression per RECIST 1.1, or death due to any cause (in the absence of progression), whichever occurs first.
Progression Free Survival (PFS) in the intent to treat (ITT) population
PFS is defined as the time from randomization until radiological progression per RECIST 1.1 or death due to any cause (in the absence of progression), whichever occurs first.
Objective Response Rate (ORR) in the PDL1 ≥ 1% population
ORR is defined as the proportion of participants who have a confirmed CR or confirmed PR using RECIST 1.1.
