Gemox Combined With Anlotinib and Sintilimab in Advanced cHCC-ICC

Gemox Combined With Anlotinib and Sintilimab in Advanced Combined Hepatocellular-cholangiocarcinoma: an Exploratory Study

The Purpose of This Study is to Evaluate the Efficacy and Safety of Gemox combined with Anlotinib and Sintilimab as first-lineTherapy for Patients With advanced combined hepatocellular-cholangiocarcinoma.

Study Overview

• Status: Not yet recruiting
• Conditions: Combined Hepatocellular Cholangiocarcinoma
• Intervention / Treatment: Drug: gemcitabine ,oxaliplatin,anlotinib,Sintilimab

Detailed Description

Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) accounts for 0.4%-14.2% of primary hepatocellular carcinoma. As imaging and pathological diagnostic techniques for liver tumors have improved, the detection rate of cHCC-CCA puncture biopsies and surgical procedures has increased. Oxaliplatin-containing chemotherapy was previously recommended for the treatment of advanced cHCC-ICC, but its efficacy was not satisfactory. Targeted therapy and immunotherapy have made breakthroughs in both advanced HCC and CCA, providing a new direction for exploration in the treatment of advanced cHCC-CCA. Currently, targeted combination immunotherapy has become the preferred first-line treatment strategy for advanced HCC. Chemotherapy combined with immunotherapy is also the preferred first-line treatment option for advanced CCA. To balance the treatment of HCC and ICC, this study further investigates the efficacy and safety of Gemox chemotherapy combined with anlotinib and Sintilimab(anti-PD-1 monoclonal antibody) immunotherapy in advanced cHCC-ICC, to provide a new treatment strategy and reference for the clinical treatment of advanced cHCC-CCA patients.

8. .Strict contraception.
9. .Patients must be able to understand and be willing to sign the written informed consent form. A signed informed consent form must be appropriately obtained prior to the conduct of any trial-specific procedure.

Exclusion Criteria:

1. Has a history of severe allergic reactions to chimeric, human or humanized antibodies, or fusion proteins.
2. Pregnant or lactating women, men and women of childbearing age who are unwilling or unable to take effective contraceptive measures;
3. History of other malignant tumors in the past 5 years, except for malignant tumors that have received treatment for the purpose of cure, and have no known active diseases for ≥ 5 years before the first administration, and have a low potential risk of recurrence; Fully treated non Melanoma skin cancer or malignant lentigo without disease evidence; Fully treated Carcinoma in situ, no disease evidence;
4. Moderate or higher amounts of pleural and ascitic fluid with clinical symptoms;
5. Active bleeding or abnormal coagulation function (PT>16s, APTT>43s, INR>1.5) × ULN), with a tendency to bleed or undergoing thrombolysis, anticoagulation, or antiplatelet therapy;
6. Hepatic encephalopathy;
7. Within the past 6 months, there has been a history of gastrointestinal bleeding or a clear tendency for gastrointestinal bleeding, such as known local active ulcer lesions, fecal occult blood+or above, which cannot be included in the group; If there is continuous fecal occult blood, gastroscopy should be performed;
8. Patients with severe gastroesophageal varices who require interventional treatment;
9. Untreated active hepatitis B. (Note: Hepatitis B patients who receive antiviral treatment and whose HBV Viral load is less than 2000IU/ml can be allowed to participate in the study)
10. Active hepatitis C, that is, those who are anti-HCV positive or HCV-RNA positive and have abnormal liver function;
11. Having a history of psychotropic substance abuse, unable to quit, or having a history of mental disorders;
