- NCT05771480
- Lead Sponsor
- AstraZeneca
- Brief Summary
A study to assess the safety and efficacy of durvalumab in combination with gemcitabine-based chemotherapy regimens in participants with aBTC.
- Detailed Description
This study involves assessing the safety and efficacy of durvalumab in combination with different gemcitabine-based chemotherapy regimens as first line therapy for aBTC. The target population of interest in this study is participants with aBTC who are ≥ 18 years of age and above legal age per local regulations with WHO/ECOG PS of 0 to 2 at enrolment and who are not eligible for locoregional therapy. Participants with WHO/ECOG PS 2 will be capped at 20% of the overall treated participant population.
The study consists of 4 periods: screening period (Day-28 to Day -1), treatment period up to 8 cycles of gemcitabine-based chemotherapy regimens with durvalumab, maintenance treatment with durvalumab alone or in combination with gemcitabine-based chemotherapy (with the exception of paclitaxel), and then safety and survival follow-up.

- Primary Outcome Measures
Name Time Method Number of participants with Grade 3 or 4 possibly related adverse event (PRAE) Within 6 months after the initiation of Investigational Medicinal Product (IMP) PRAE is defined as an AE which has been assessed by the investigator to be possibly related to IMP.
- Secondary Outcome Measures
Name Time Method Progression-Free Survival (PFS) From the date of the first dose of IMP until until the date of objective PD or death [approx. up to 33 months] PFS is defined as the time from the first dose of IMP until the date of disease progression (PD) or death due to any cause.
Overall Survival (OS) From the date of the first dose of IMP until death due to any cause [approx. upto 33 months] OS is defined as the time from the date of the first dose of IMP until death due to any cause.
Objective Response Rate (ORR) From the date of first dose of IMP until progression, or the last evaluable assessment in the absence of progression [assessed up to 33 months] ORR is defined as the proportion of participants who have a confirmed CR or confirmed PR, as determined by the investigator at local site per RECIST 1.1.
Duration of Treatment (DOT) From date of start of IMP, until 27 days after last dose of IMP or date of death [approx. up to 33 months] DOT is defined as time on study intervention.
Number of participants with IRRs and hypersensitivity/anaphylactic reactions From the date of first dose of IMP until 90 days following discontinuation of the last dose of IMP [approx. up to 33 months] To assess the safety and tolerability profile of durvalumab combined with background gemcitabine-based chemotherapy
Disease Control Rate (DCR) Week 24 and Week 32 DCR is defined as the % of participants who have a best objective response of complete response or partial response (by week 24 or 32), or who have stable disease for 24 or 32 weeks.
Duration of Response (DOR) From the date of first documented response until the first date of documented progression or death in the absence of disease progression [approx. up to 33 months] DOR is defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression.
Number of participants with AEs, including PRAEs, adverse events of special interest (AESIs), immune-mediated adverse events (imAEs) and serious adverse events (SAEs) From the date of first dose of IMP until long-term follow-up i.e. until 90 days following discontinuation of the last dose of IMP [approx. up to 33 months] To assess the safety and tolerability profile of durvalumab combined with background gemcitabine-based chemotherapy
European Organization for Research and Treatment of Cancer 30-item core quality of life questionnaire (EORTC QLQ C-30) From date of first dose of IMP, until the date of the first clinically meaningful deterioration [approx. up to 33 months] To assess disease and treatment related symptoms and HRQoL. EORTC QLQ-C30 consists of 30 items and measures symptoms, functioning, and global health status/QoL for all cancer types. Questions are grouped into 5 multi-item functional scales (physical, role, emotional, cognitive, and social), 3 multi-item symptom scales (fatigue, pain, and nausea/vomiting), a 2-item global QoL scale, 5 single items assessing additional symptoms commonly reported by cancer participants (dyspnoea, loss of appetite, insomnia, constipation, and diarrhoea), and one item on the financial impact of the disease. The EORTC QLQ-C30 is a valid and reliable PRO instrument in this participant population
EORTC QLQ-BIL21 Score From date of first dose of IMP, until the date of the first clinically meaningful deterioration [approx. up to 33 months] To assess disease- and treatment related symptoms and HRQoL. The EORTC QLQ-BIL21 is a disease-specific (cholangiocarcinoma and cancer of the gallbladder) questionnaire. It consists of 21 items including one question each for side effects, equipment issues, and weight loss, as well as 5 scales (eating symptoms, jaundice symptoms, tiredness, pain, and anxiety). A higher score indicates greater difficulties. The EORTC QLQ-BIL21 is a valid and reliable PRO instrument in this participant population.
