Официальное название
A Prospective, Non-interventional Study of Gemcitabine/Cisplatin Combined With PD-1/PD-L1 Inhibitor as First-line Treatment in Treatment-naïve Advanced Biliary Tract Cancer Patients: Efficacy and Immune Microenvironment Dynamics
Обзор
To evaluate the efficacy and immune microenvironment changes in treatment-naïve advanced biliary tract cancer (BTC) patients receiving first-line standard therapy with gemcitabine/cisplatin (GemCis) combined with PD-1/PD-L1 inhibitors.
Подробное описание
This is a prospective, non-interventional, observational study evaluating the efficacy and immune microenvironment changes in treatment-naïve advanced biliary tract cancer (BTC) patients receiving first-line standard therapy with gemcitabine/cisplatin (GemCis) combined with PD-1/PD-L1 inhibitors. The primary endpoint is objective response rate (ORR), with secondary endpoints including disease control rate (DCR), duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS), and immune profiling of tumor tissue and peripheral blood before and after treatment.
Вмешательства
- Препарат GemCis plus PD-1/PD-L1 inhibitor
Gemcitabine: 1000 mg/m², intravenous infusion, on Day 1 and Day 8 Cisplatin: 25 mg/m², intravenous infusion, on Day 1 and Day 8 PD-1/PD-L1 inhibitor: An approved agent (e.g., Pembrolizumab, Nivolumab, Atezolizumab, etc.) will be selected based on clinical practice and administered at standard doses and schedules. Each treatment cycle lasts 21 days, continuing until disease progression, unacceptable toxicity, or patient/physician decision to discontinue.
