Brief summary: This study is a single-arm Phase II clinical trial aiming to evaluate the safety and efficacy of HAIC combined with Cadonilimab and Regorafenib as second-line treatment for unresectable intrahepatic cholangiocarcinoma.

The study plans to enroll approximately 45 participants. All enrolled participants will receive continuous treatment: HAIC-Gemox: Gemcitabine 1000mg/m2 on Day 1 + Oxaliplatin 85mg/m2 on Day 1, every 3 weeks (Q3W), for up to 6 treatment cycles, Cadonilimab(6mg/kg, D2, Q3W) and Regorafenib (80mg QD, Q3W) until the investigator determines that there is no longer any clinical benefit (based on comprehensive assessment including RECIST v1.1 imaging evaluation and clinical condition), intolerable toxicity, initiation of new anti-tumor therapy, or meeting other criteria for treatment discontinuation, whichever occurs first.


Eligibility criteria: Inclusion Criteria:

To be eligible for enrollment in the study, participants must meet the following inclusion criteria:

1. Voluntarily provide written informed consent.
2. Age at enrollment is ≥18 years and ≤75 years, both males and females.
3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
4. Expected survival period of ≥3 months.
5. Patients with histologically or cytologically confirmed unresectable intrahepatic cholangiocarcinoma. Patients who have failed standard treatment (standard treatment includes gemcitabine plus cisplatin plus pembrolizumab, gemcitabine plus gemcitabine plus oxaliplatin, capecitabine plus oxaliplatin, chemotherapy mainly based on albumin-bound paclitaxel, 5-fluorouracil (5-FU) plus platinum-based therapy) or are intolerant to standard treatment, or patients for whom standard treatment is not accessible. Note: Patients who have received adjuvant/neoadjuvant chemotherapy targeting non-metastatic disease with curative intent and experience disease progression within ≤6 months after the last treatment are eligible.
6. At least one measurable lesion according to RECIST v1.1 that can be accurately measured repeatedly. Note: Brain metastases cannot be considered as target lesions.
7. Adequate organ function determined by the following requirements:

   1. Hematology (no use of any blood components or growth factors within 7 days prior to starting the study treatment): i. Absolute Neutrophil Count (ANC) ≥ 1.5 × 109/L (1,500/mm3). ii. Platelet count ≥ 80 × 109/L (100,000/mm3). iii. Hemoglobin ≥ 90 g/L.
   2. Kidney:

   i. Serum creatinine ≤ 1.5 × Upper Limit of Normal (ULN). ii. Calculated creatinine clearance\* (CrCl) ≥ 50 mL/min.

   \* CrCl will be calculated using the Cockcroft-Gault formula (Cockcroft-Gault formula).

   CrCl (mL/min) = {(140 - age) × body weight (kg) × F} / (SCr (mg/dL) × 72) For males, F = 1; for females, F = 0.85; SCr = serum creatinine. iii. Urine protein ≤ 1+ or 24-hour urinary protein quantification \< 1.0 g. c) Liver: i. Total bilirubin (TBil) ≤ 3 × ULN. ii. AST and ALT ≤ 5 × ULN. iii. Serum albumin (ALB) ≥ 28 g/L. d) Coagulation function: i. International Normalized Ratio (INR) and Activated Partial Thromboplastin Time (APTT) ≤ 1.5 × ULN (unless the subject is receiving anticoagulant therapy and coagulation parameters \[PT/INR and APTT\] are within the expected range for anticoagulant treatment at screening).

   e) Cardiac function: i. Left Ventricular Ejection Fraction (LVEF) ≥ 50%.
8. Female participants of childbearing potential must undergo urine or serum pregnancy testing within 3 days prior to the first dose of study medication (if the urine pregnancy test results cannot be confirmed as negative, a serum pregnancy test must be conducted, with the serum pregnancy test result being definitive). If female participants of childbearing potential engage in sexual activity with a nonsterilized male partner, they must use an acceptablemethod of contraception from the start of screening and agree to continue using contraception for up to 120 days after the last dose of the study medication. The decision to stop contraception after this time should be discussed with the investigator.
9. Male participants with a female partner of childbearing potential must use effective contraception from the start of screening until 120 days after the last dose of the study medication. The decision to stop contraception after this time should be discussed with the investigator.
10. Participants must be willing and able to comply with the scheduled visits, treatment plan, laboratory tests, and other study requirements.

Exclusion Criteria:

Subjects meeting any of the following criteria will be ineligible to participate in this study:
