| Placebo Arm | Placebo comparator | Placebo + Gemcitabine + Cisplatin Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Survival (OS)
Overall Survival (OS) was defined as the time from the date of randomization until death due to any cause. Any patient not known to have died at the time of analysis was censored based on the last recorded date on which the patient was known to be alive. Median OS was calculated using the Kaplan-Meier technique. The second interim analysis was pre-specified after approximately 397 OS events occurred in both arms (59% maturity).
Measured: From date of randomization until death due to any cause. Assessed up to maximum of approximately 27 months (from date of randomization to primary analysis data cut-off)
Overall Survival (OS) Rate at 18 Months
Overall Survival (OS) was defined as the time from the date of randomization until death due to any cause. Any patient not known to have died at the time of analysis was censored based on the last recorded date on which the patient was known to be alive. Median OS was calculated using the Kaplan-Meier technique. The second interim analysis was pre-specified after approximately 397 OS events occurred in both arms (59% maturity).
Measured: From date of randomization until death due to any cause. Calculated at 18 months using the Kaplan-Meier technique.
Overall Survival (OS) Rate at 24 Months
Overall Survival (OS) was defined as the time from the date of randomization until death due to any cause. Any patient not known to have died at the time of analysis was censored based on the last recorded date on which the patient was known to be alive. Median OS was calculated using the Kaplan-Meier technique. The second interim analysis was pre-specified after approximately 397 OS events occurred in both arms (59% maturity).
Measured: From date of randomization until death due to any cause. Calculated at 24 months using the Kaplan-Meier technique.
Secondary outcomes (11)
Progression-free Survival (PFS)
PFS based on investigator assessments according to RECIST version 1.1 was defined as time from date of randomization until date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdrew from randomized therapy or received another anticancer therapy prior to progression. Progression (i.e., PD) was defined as at least a 20% increase in the sum of diameters of target lesions (TLs) and an absolute increase of ≥5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters, or a measurable increase in a non-target lesion, or the appearance of new lesions. Median PFS was calculated using the Kaplan-Meier technique.
Measured: Tumor assessments every 6 weeks after randomization for the first 24 weeks and then every 8 weeks thereafter until date of RECIST 1.1 defined radiological progressive disease or death. Assessed up to maximum of approximately 27 months.
Progression-free Survival (PFS) Rate at 9 Months
PFS based on investigator assessments according to RECIST version 1.1 was defined as time from date of randomization until date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdrew from randomized therapy or received another anticancer therapy prior to progression. Progression (i.e., PD) was defined as at least a 20% increase in the sum of diameters of target lesions (TLs) and an absolute increase of ≥5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters, or a measurable increase in a non-target lesion, or the appearance of new lesions. Median PFS was calculated using the Kaplan-Meier technique.
Measured: Tumor assessments every 6 weeks after randomization for the first 24 weeks and then every 8 weeks thereafter until date of RECIST 1.1 defined radiological progressive disease or death. Calculated at 9 months using the Kaplan-Meier technique.
Progression-free Survival (PFS) Rate at 12 Months
PFS based on investigator assessments according to RECIST version 1.1 was defined as time from date of randomization until date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdrew from randomized therapy or received another anticancer therapy prior to progression. Progression (i.e., PD) was defined as at least a 20% increase in the sum of diameters of target lesions (TLs) and an absolute increase of ≥5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters, or a measurable increase in a non-target lesion, or the appearance of new lesions. Median PFS was calculated using the Kaplan-Meier technique.
Measured: Tumor assessments every 6 weeks after randomization for the first 24 weeks and then every 8 weeks thereafter until date of RECIST 1.1 defined radiological progressive disease or death. Calculated at 12 months using the Kaplan-Meier technique
Objective Response Rate (ORR)
Disease assessments based on investigator assessments were determined by using RECIST version 1.1 guidelines. The ORR was defined as the percentage of patients with confirmed complete response (CR) or confirmed partial response (PR). The CR was defined as disappearance of all target and non-target lesions and no new lesions. The PR was defined as >= 30% decrease in the sum of diameters of target lesions (compared to baseline) and no new non-target lesion. A confirmed CR or PR was defined as 2 CRs or 2 PRs with no evidence of progression in-between. Patients who discontinued randomized treatment without progression, received a subsequent anti-cancer therapy and then responded were not included as responders for ORR.
Measured: Tumor assessments (per RECIST 1.1) every 6 weeks for the first 24 weeks relative to the date of randomization and then every 8 weeks thereafter. Assessed up to maximum of approximately 27 months.
Duration of Response (DoR)
The DoR was defined as the time from the date of first documented OR (confirmed CR or confirmed PR) until date of documented progression (PD) based on investigator assessments by using RECIST version 1.1 or death in absence of disease progression (i.e. date of PFS event or censoring - date of first response + 1) . A confirmed CR was defined in above outcome measures. The PD was defined at least 20% increase in sum of diameters of target lesions (compared with nadir at 2 consecutive visits with an absolute increase of 5 mm), unequivocal progression of existing non-target lesions or new lesion. For participants who were alive and no documented PD at the time of data cutoff for analysis, DoR was censored at the last evaluable disease assessment date. Median DoR was calculated using Kaplan-Meier method.
Measured: Tumor assessments (per RECIST 1.1) every 6 weeks for first 24 weeks relative to the date of randomization and then every 8 weeks thereafter. Assessed up to maximum of approximately 27 months.
Duration of Response (DoR): Percentage Remaining in Response at 9 Months
The DoR was defined as the time from the date of first documented OR (confirmed CR or confirmed PR) until date of documented progression (PD) based on investigator assessments by using RECIST version 1.1 or death in absence of disease progression (i.e. date of PFS event or censoring - date of first response + 1) . A confirmed CR was defined in above outcome measures. The PD was defined at least 20% increase in sum of diameters of target lesions (compared with nadir at 2 consecutive visits with an absolute increase of 5 mm), unequivocal progression of existing non-target lesions or new lesion. For participants who were alive and no documented PD at the time of data cutoff for analysis, DoR was censored at the last evaluable disease assessment date. Median DoR was calculated using Kaplan-Meier method.
Measured: Tumor assessments (per RECIST 1.1) every 6 weeks for first 24 weeks relative to the date of randomization and then every 8 weeks thereafter. Calculated at 9 months using the Kaplan-Meier technique
Duration of Response (DoR): Percentage Remaining in Response at 12 Months
The DoR was defined as the time from the date of first documented OR (confirmed CR or confirmed PR) until date of documented progression (PD) based on investigator assessments by using RECIST version 1.1 or death in absence of disease progression (i.e. date of PFS event or censoring - date of first response + 1) . A confirmed CR was defined in above outcome measures. The PD was defined at least 20% increase in sum of diameters of target lesions (compared with nadir at 2 consecutive visits with an absolute increase of 5 mm), unequivocal progression of existing non-target lesions or new lesion. For participants who were alive and no documented PD at the time of data cutoff for analysis, DoR was censored at the last evaluable disease assessment date. Median DoR was calculated using Kaplan-Meier method.
Measured: Tumor assessments (per RECIST 1.1) every 6 weeks for first 24 weeks relative to the date of randomization and then every 8 weeks thereafter. Calculated at 12 months using the Kaplan-Meier technique
Disease Control Rate (DCR) - Overall
Disease control rate based on investigator assessments according to RECIST version 1.1 was defined as the rate of best objective response of complete response (CR), partial response (PR) or stable disease (SD).
Measured: Tumor assessments (per RECIST 1.1) every 6 weeks for the first 24 weeks relative to the date of randomization and then every 8 weeks thereafter. Assessed up to maximum of approximately 27 months.
Disease Control Rate (DCR) - 24 Weeks
Disease control rate based on investigator assessments according to RECIST version 1.1 was defined as the rate of best objective response of complete response (CR) or partial response (PR) by week 24 or who have stable disease (SD) at least 24 weeks following start of treatment.
Measured: Tumor assessments (per RECIST 1.1) every 6 weeks for the first 24 weeks relative to the date of randomization.
Disease Control Rate (DCR) - 32 Weeks

Primary outcome
Overall Survival (OS)
Time frame: From date of randomization until death due to any cause. Assessed up to maximum of approximately 27 months (from date of randomization to primary analysis data cut-off)
Overall Survival (OS) was defined as the time from the date of randomization until death due to any cause. Any patient not known to have died at the time of analysis was censored based on the last recorded date on which the patient was known to be alive. Median OS was calculated using the Kaplan-Meier technique. The second interim analysis was pre-specified after approximately 397 OS events occurred in both arms (59% maturity).
Overall Survival (OS) Rate at 18 Months
Time frame: From date of randomization until death due to any cause. Calculated at 18 months using the Kaplan-Meier technique.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Durvalumab in people with Biliary Tract Neoplasms, run by AstraZeneca at 126 sites in 17 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 126 sites in China, United States, Japan, Russia, Taiwan and 12 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 13 Apr 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall Survival (OS) (time frame: From date of randomization until death due to any cause. Assessed up to maximum of approximately 27 months (from date of randomization to primary analysis data cut-off)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03875235, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2026.
