詳細な説明

This trial is a single-arm interventional clinical study to evaluate the efficacy and safety of neoadjuvant gemcitabine-cisplatin plus Envafolimab in resectable biliary tract malignancies patients with high-risk of recurrence. Patients with high-risk factors for recurrence. The criteria were defined as meeting at least one of the following: a. Preoperative CA19-9 ≥ 200 U/mL; b. Tumor diameter ≥5 cm or multiple tumor nodules on imaging; c. Regional lymph node metastasis with a short-axis diameter ≥ 1.0 cm on imaging; d. Vascular invasion (portal vein or hepatic artery) on imaging; e. Low or undifferentiated histologic grade. The primary endpoint: Major Pathologic Response (MPR). Secondary endpoints: Overall Survival (OS), Disease-free survival (DFS), Objective Response Rate (ORR) per the Response Evaluation Criteria In Solid Tumors (RECIST v1.1), Pathologic Response Rate (PCR), and R0 resection rate. The incidence and severity of adverse events (AEs), serious adverse events (SAEs), and laboratory test abnormalities judged as per the CTCAE v5.0 criteria. Exploratory endpoint: Relationship between carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 125 (CA125), Pathological biomarker expression, spatial transcriptome (if samples are sufficient), gut microbiome metagenome sequencing, and treatment response.

Coagulation function: international normalized ratio (INR) ≤ 1.2; c. Alanine transaminase (ALT) and aspartate transaminase (AST) ≤ 3 times the upper limit of normal (ULN); d. Serum albumin ≥ 3.5 g/dL; total bilirubin ≤ 1.5 times the ULN. Patients with obstructive jaundice who meet the eligibility criteria after percutaneous transhepatic cholangial drainage or endoscopic retrograde cholangiopancreatography treatment are also eligible for enrollment; e. Child-Pugh class A or B; f. Serum creatinine ≤ 1.5 times the ULN;
  • Patients with high-risk factors for recurrence. The criteria are defined as meeting at least one of the following: a. Preoperative CA19-9 ≥ 200 U/mL; b. Tumor diameter ≥ 5 cm or multiple tumor nodules on imaging; c. Regional lymph node metastasis with a short-axis diameter ≥ 1.0 cm on imaging; d. Vascular invasion (portal vein or hepatic artery) on imaging; e. Low or undifferentiated histologic grade;
  • Participants who have at least 1 measurable lesion (RECIST v1.1);
  • Be able to provide fresh stool samples and liver samples if undergoing surgery.

Exclusion Criteria

  • Pathological diagnosis of hepatocellular carcinoma, mixed hepatocellular carcinoma, and other non-cholangiocarcinoma malignant tumor components;
  • Prior systemic therapy for BTC, including immunotherapy, targeted therapy, or chemotherapy;
  • History of other prior or concurrent malignancies, except those with complete treatment and disease-free survival for more than 5 years;
  • Presence of an active, known or suspected autoimmune disease, or requirement for long-term systemic corticosteroid therapy (equivalent to ≥ 10 mg prednisone daily) or other immunosuppressive agents. Participants using inhaled or topical corticosteroids will not be excluded;
  • Presence of ascites, hepatic encephalopathy, sclerosing cholangitis, or other concurrent organ dysfunctions that would preclude tolerance of general anesthesia or hepatectomy;
  • Women who are breastfeeding or pregnant;
  • Any other factors that, in the investigator's judgment, may compromise participant safety or trial compliance, including serious comorbidities requiring ongoing treatment, clinically significant laboratory abnormalities, or relevant social or family-related issues.

介入・治療
実験的:GC Chemotherapy Plus Envafolimab Arm
Participants first receive GC chemotherapy plus envafolimab every 3 weeks (Q3W) for a total of 3 cycles (each cycle is 21 days). Eligibility for surgery is then assessed; eligible patients undergo radical resection.

First:

Envafolimab: 400 mg on Day 1, repeated every 3 weeks (Q3W). GC chemotherapy: Gemcitabine: 1000 mg/m2 in 100 mL of 0.9% sodium chloride injection, administered intravenously over 30 minutes on Days 1 and 8, repeated Q3W. Cisplatin: 25 mg/m2 in 500 mL of 5% glucose injection, administered intravenously over 2 hours on Day 1 and 8, repeated Q3W.

Of note, no target drugs is involved.

Second:

Radical resection eligibility will be assessed by the investigator; those with indeterminate resectability require additional MDT discussion confirmation. The criteria for radical resection:

  1. No invasion of the main trunk of the hepatic vein, portal vein, or inferior vena cava;
  2. No distant metastasis except for hilar lymph node metastases;
  3. Minimum distance between surgical margin and tumor border ≥ 0.5 cm;
  4. Residual liver volume ≥ 30% (≥ 40% for participants with cirrhosis).
