About

This study is designed to see whether Apatinib is effective in treating patients with advanced refractory biliary tract cancers.

Full description

Biliary tract cancers (BTC) includes cholangiocarcinoma and gallbladder carcinoma (GBC). The systematic treatment based on gemcitabine plus cisplatin is recommended as the current standard chemotherapy for unresectable or metastatic BTC. There is no standard recommendation for second line therapy.

Apatinib is a tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2(VEGFR-2).

This study was conducted to assess the efficacy and safety of Apatinib in patients with advanced refractory BTC who had received first-line chemotherapy.

Enrollment: 39 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

1. Must have histologically or cytologically documented carcinoma primary to the intra- or extra-hepatic biliary system or gall bladder with clinical and/or radiologic evidence of unresectable, locally advanced or metastatic disease.
2. Patients with ampullary carcinoma are not eligible.
3. Must have failed or are intolerant to one line of systemic treatment but no more than 2 prior lines of systemic chemotherapy for advanced BTC. Patients who received adjuvant chemotherapy and had evidence of disease recurrence within 6 months of completion of the adjuvant treatment are also eligible. If the patient received adjuvant treatment and had disease recurrence after 6 months, patients will only be eligible after failing or having intolerance to one line of systemic chemotherapy used to treat the disease recurrence.

For patients who have received prior radiation, cryotherapy, radiofrequency ablation, therasphere, ethanol injection, transarterial chemoembolization (TACE) or photodynamic therapy, the following criteria must be met: 28 days have elapsed since that therapy; Lesions that have not been treated with local therapy must be present and measureable.
9. Must be able to understand and be willing to sign the written informed consent form. Must be willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other study requirements.
10. All acute toxic effects of any prior treatment have resolved to NCI-CTCAE v4.0 Grade 1 or less at the time of signing the Informed Consent Form (ICF) except for alopecia.
11. Adequate bone marrow, liver and liver function.
