A Clinical Study of DEB-TACE Combined With Surufatinib and Camrelizumab in the Treatment of Inoperable or Metastatic ICC

Study Overview
=================
Brief Summary
-----------------
At present, for advanced Intrahepatic Cholangiocarcinoma（ICC）, the effect of single treatment is not good.So far, superselective drug-eluting bead transarterial chemoembolization（DEB-TACE） is a good method for the treatment of local lesions in advanced ICC.Studies have shown that the combination of sovantinib and immunotherapy has also shown encouraging results, and patients are well tolerated.Therefore, we designed DEB-TACE combined with Surufatinib and Camrelizumab for the exploratory study of inoperable or metastatic ICC, in order to provide a safe, effective and tolerable option for patients with ICC, prolong their survival time and improve their quality of life.

Detailed Description
-----------------
Study design: This is a single-arm, open, multicenter II phase clinical study to compare the efficacy and safety of DEB-TACE combined with Surufatinib and Camrelizumab in the treatment of inoperable or metastatic ICC. Study population: 20 untreated patients with inoperable or metastatic intrahepatic cholangiocarcinoma Treatment: All patients were treated with standard DEB-TACE on the first day (D1). Immediately after the first DEB-TACE, the liver function was reexamined. If the liver function was grade Child-Pugh A, Camrelizumab was given intravenously once every 3 weeks (D1) on the same day, 200mg/, once every 3 weeks (D1). Surufatinib capsule was given orally to 250mg within 1 hour after breakfast on the second day (D2) after the first DEB-TACE. The drug was given continuously once a day and stopped on the same day of each DEB-TACE. The combination of drugs for 3 weeks is a cycle.The treatment continued until the patient developed the disease or met the other criteria for terminating the study. Curative effect evaluation： The tumor condition was evaluated by imaging method at D28 (±7 days) after each DEB-TACE, until the curative effect was evaluated as PD or unsuitable for further treatment. After 3 times of DEB-TACE treatment, the tumor efficacy was evaluated every 12 weeks (±7 days) from 6 months after the first DEB-TACE treatment until disease progression (Response Evaluation Criteria In Solid Tumors（RECIST）1.1) or death (during treatment) or toxicity intolerable. The tumor treatment and survival status after disease progression were recorded.

At least one measurable lesion (according to RECIST1.1 standard); its diameter ≥ 1cm was accurately measured by magnetic resonance imaging (MRI) enhancement or computed tomography (CT) enhancement, and the target lesion had not received local treatment in the past (including not limited to hepatic arterial Infusion chemotherapy, radiofrequency ablation, argon-helium knife, radiotherapy, etc.); No serious organic diseases of heart, lung, brain and other organs; The functions of major organs and bone marrow are basically normal: Blood routine: WBC ≥ 4.0x10^9/L, neutrophils ≥ 1.5x10^9/L, platelets ≥ 80x10^9/L, hemoglobin ≥ 90 g/L International standardized ratio (INR) ≤ 1.5 × upper limit of normal value (ULN), and activated partial thromboplastin time (APTT) ≤ 6sbot liver function: serum total bilirubin ≤ 2xULN ;ALT/ AST ≤ 2xULN; serum albumin ≥ 28g/L. Renal function: serum creatinine ≤ 1.5xULN or eGFR ≥ 60%, and creatinine clearance rate (CCr) 60ml / min; excluding urinary tract infection, urine routine showed that urinary protein < 2+, 24-hour urine protein should be collected from ≥ 2 + patients < 1g cardiac function was normal, left ventricular ejection fraction (LVEF) ≥ 50% detected by two-dimensional echocardiography. Fertile male or female patients voluntarily used effective contraceptive methods during the study period and within 6 months of the last study, such as double barrier contraceptives, condoms, oral or injection contraceptives, intrauterine devices, etc. All female patients will be considered fertile unless the female patient has undergone natural menopause, artificial menopause or sterilization (such as hysterectomy, bilateral adnexectomy or radioactive ovarian irradiation). Exclusion Criteria: Participated in clinical trials of other antineoplastic drugs within 4 weeks before entering the group. Received any surgery or invasive treatment or operation (except venous catheterization, puncture and drainage, etc.) within 4 weeks before the start of the group; History of hepatectomy, history of TACE treatment, previous immune and targeted therapy; The researchers determined that liver metastases accounted for 70% or more of the total liver volume; Patients who have previously received organ transplants or planned organ transplants; Patients with obstructive jaundice but not as expected; Suffered from other malignant tumors in the past 5 years, except basal cell or squamous cell carcinoma of the skin after radical resection, or cervical carcinoma in situ; Patients who have had any brain metastases or are currently suffering from brain metastases; In the first study, he took other strong inducers or inhibitors of CYP3A4 within 2 weeks before medication; Received any operation (except biopsy) or invasive treatment or operation within 4 weeks before the start of the group, and the surgical incision did not completely heal (except venous catheterization, puncture and drainage, etc.); The researchers judged clinically significant electrolyte abnormalities; At present, the patients have hypertension that cannot be controlled by drugs, which is defined as systolic blood pressure ≥ 140 mmHg and / or diastolic blood pressure ≥ 90 mmHg. Urine routine showed that the amount of urinary protein was more than 2 grams and the amount of 24-hour urinary protein was more than 1.0 g. The researchers determined that during the follow-up study, the tumor was most likely to invade important blood vessels and cause fatal massive bleeding; Patients with obvious evidence or history of bleeding tendency within 3 months (bleeding > 30 mL within 3 months, hematemesis, black feces, hematochezia), hemoptysis (fresh blood > 5 mL within 4 weeks), hereditary or acquired history of bleeding or coagulation dysfunction. There were significant clinical bleeding symptoms or definite bleeding tendency in the first 3 months, such as gastrointestinal bleeding, hemorrhagic gastric ulcer, etc.; Cardiovascular diseases with significant clinical significance, including, but not limited to, acute myocardial infarction, severe / unstable angina pectoris or coronary artery bypass grafting within 6 months before admission; congestive heart failure New York Heart Association (NYHA) grade > 2; ventricular arrhythmias requiring medication; electrocardiogram (ECG) showed QTc interval ≥ 480ms; Active or uncontrolled severe infection (≥ （Common Terminology Criteria for Adverse Events）CTCAE 2 grade infection); Due to any unalleviated toxicity higher than CTCAE 1 grade caused by any previous anticancer therapy, excluding alopecia, lymphocytopenia and oxaliplatin-induced neurotoxicity ≤ 2; Women who are pregnant (positive for pre-medication pregnancy test) or breastfeeding; Any other disease, with clinically significant metabolic abnormalities, physical examination abnormalities or laboratory abnormalities, according to the researchers, there is reason to suspect that the patient has a disease or state that is not suitable for the use of research drugs (such as having seizures and requiring treatment), or will affect the interpretation of the results of the study, or put the patient at high risk; Known human immunodeficiency virus (HIV) infection Patients with any active, known or suspected autoimmune diseases (including but not limited to: myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, enteritis, multiple sclerosis, vasculitis, glomerulonephritis, uveitis, hypophysitis, hyperthyroidism, etc.) Known to have allergic reactions to other monoclonal antibodies or to any component of sovantinib; The researchers judged that patients have other factors that may affect the results of the study or lead to the termination of the study, such as alcohol abuse, drug abuse, and other serious diseases (including mental illness) that need to be combined with treatment. there are serious laboratory abnormalities, accompanied by family or social factors, which will affect the safety of patients.
