A Trial Evaluating Surufatinib Efficacy and Safety in Biliary Tract Carcinoma Patients

This is an interventional treatment trial for Biliary Tract Cancer Read More

Inclusion Criteria:

1. Patients are fully informed about the study and voluntarily sign the informed consent (prior to the implementation of any specific procedure for the trial);
2. 18-75 years old (inclusive);
3. Patients with histologically or cytologically confirmed unresectable or metastatic BTC, including intrahepatic cholangiocarcinoma (IHCC), extrahepatic cholangiocarcinoma (EHCC) and gallbladder cancer (GBC);

4. Patients have failed first-line standard systemic chemotherapy. A first-line standard systemic chemotherapy is defined as a regimen of gemcitabine combined with platinum-based therapy. The failure of a first-line standard chemotherapy is defined by progressive disease during the treatment or within 6 months after the last treatment, or intolerable toxicity during the treatment.

   Note: a. The time of first-line medication is ≥ 1 cycle of combination chemotherapy; b. Neoadjuvant or adjuvant chemotherapy is allowed in the early stage, and should be considered failed as a first-line systemic chemotherapy for progressive disease if progressive disease/recurrence occurs during the course of the neoadjuvant/adjuvant therapy or within 6 months after the end of treatment; c. The previous first-line standard chemotherapy does not contain any small molecular anti-angiogenesis agents or monoclonal antibodies, or any drugs related to tumor immunity;

5. ECOG performance status of 0 or 1 (Annex 1);
6. Liver function with a modified Child-Pugh score of < 7;
7. Confirmed measurable (or evaluable) lesions that meet the requirements of RECIST 1.1;
8. Expected survival of ≥ 12 weeks;
9. Fertile male or female patients shall volunteer to use effective contraceptive methods, such as double barrier contraception, condoms, oral or injected contraceptives, and intrauterine devices, during the study period and within 90 days after the last dosing of the investigational drug. All female patients will be considered fertile unless they have had natural menopause, or artificial menopause or sterilization (such as hysterectomy, bilateral adnexectomy or ovarian radiation).

Exclusion Criteria:

1. Received a systemic anti-cancer therapy that has been approved or in development, including chemotherapy, radical radiotherapy, bio-immunotherapy, targeted therapy, and treatment by traditional Chinese medicines (if the instructions of the traditional Chinese medicines specifies clear indications for anti-tumor therapy, the patient may be enrolled after an 1 week of washout period), within 4 weeks prior to randomization;
2. Received a systemic chemotherapy (a neoadjuvant or adjuvant chemotherapy except those that have not failed within 6 months) other than gemcitabine combined with platinum-based therapy (such as fluorouracil-based chemotherapy) prior to randomization; or received an anti-tumor immunotherapy, such as PD-1 and PD-L1 therapies;
3. Received any surgery or invasive treatment/operation (except venous catheterization, puncture and drainage, etc) within 4 weeks prior to randomization;
4. Received any major surgical operations within 60 days before randomization, or have any incisions that have not completely healed;
5. Received a local anti-tumor therapy such as hepatic artery interventional embolization, cryoablation of liver metastases, or radiofrequency ablation within 4 weeks prior to randomization;

6. Patients with any of the following laboratory abnormalities:

   • Absolute neutrophil count (ANC) < 1.5 × 109/L, or platelet (PLT) < 100 × 109/L, or hemoglobin (Hb) < 90 g/L;
   • Total bilirubin ≥ 1.5 × Upper Limit of Normal (ULN);
   • In the absence of liver metastasis, alanine transaminase (ALT) and/or aspartate transaminase (AST) ≥ 1.5 × ULN; in the presence of liver metastasis, ALT and/or AST ≥ 3 × ULN;
   • Serum creatinine ≥ 1.5 × ULN or creatinine clearance < 50 mL/min (calculated according to the Cockcroft-Gault formula, as shown in Annex 2);
   • Routine urinalysis shows urinary protein of ≥ 2+ or 24-hours urinary protein of ≥ 1 g;
7. Uncontrolled malignant ascites (ascites that cannot be controlled by diuretics or puncture as judged by the investigator);
8. Liver metastases accounting for half or more of the total liver volume as determined by the investigator;
9. International normalized ratio (INR) > 1.5 or activated partial thromboplastin time (APTT) > 1.5 × ULN;
10. Clinically significant electrolyte abnormalities as determined by the investigator;
11. Patients with hypertension that is uncontrollable by medications, defined as: systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg;
12. Patients with poorly controlled diabetes mellitus (fasting blood glucose ≥ CTCAE grade 2 after regular treatment);
13. Patients with any disease or condition affecting drug absorption, or patients cannot be treated via oral drug administration;
14. Patients with active gastric and duodenal ulcer, ulcerative colitis and other gastrointestinal diseases, active bleeding caused by unresected tumors, or other conditions that may lead to gastrointestinal bleeding or perforation as judged by the investigator;
15. With evidence or history of apparent bleeding tendency within 3 months prior to randomization (bleeding volume > 30 mL over 3 months, with hematemesis, melena, or hematochezia), hemoptysis (> 5 mL of fresh blood over 4 weeks), or history of thromboembolism within the past 12 months (including stroke and/or transient ischemic attack);
16. With clinically significant cardiovascular diseases, including but not limited to: acute myocardial infarction, severe/unstable angina pectoris or coronary artery bypass grafting within 6 months prior to randomization; congestive heart failure of New York Heart Association (NYHA) grade > 2; ventricular arrhythmias requiring medication; and left ventricular ejection fraction (LVEF) < 50%;
17. Other malignant tumors in the past 5 five years, except basal cell or squamous cell carcinoma that has been treated by radical operation or carcinoma in situ of the cervix;
18. Active or uncontrolled severe infection (≥ CTCAE grade 2) within 2 weeks prior to randomization;
19. Known infection of human immunodeficiency virus (HIV);
20. Known history of clinically significant liver diseases, including viral hepatitis [for known carriers of hepatitis B virus (HBV), the presence of active HBV infection, i.e., positive HBV DNA (> 1 × 104 copies/mL or > 2000 IU/mL), must be excluded; known infection of hepatitis C virus (HCV) with positive HCV RNA (> 1 × 103 copies/mL)], or other hepatitis or cirrhosis;
21. Patients with metastasis in the central nervous system (CNS) or previous brain metastasis;
22. Any unresolved toxicity (> CTCAE grade 1) from previous anti-cancer therapy, excluding alopecia or neurotoxicity of ≤ grade 2 caused by oxaliplatin;

27. Any other diseases with clinically significant metabolic abnormalities, abnormal physical observations or abnormal laboratory findings, which are judged by the investigator as evidence that the patient has a disease or condition that is unsuitable for the study drug (e.g., epileptic seizures requiring treatment), or that would interfere with the interpretation of the study results, or that may put the patient at a high risk.
