About

Oncolytic viruses can selectively replicate in and destroy tumor cells. Recent studies indicate that recombinant human adenovirus type 5 (H101), which is the first approved oncolytic virus drug in the world, shows anti-tumor effects on liver cancer. This study aims to further verify the effect and safety of recombinant human adenovirus type 5 combined with HAIC in the treatment of intrahepatic mass-forming cholangiocarcinoma.

Full description

This is a perspective, single-arm trial. According to previous studies, the PFS of HAIC for unresectable intrahepatic cholangiocarcinoma is approximately 8 - 10 months, and one year progression free rate is about 40%. We assumed that the study could detect 20% absolute difference and 1 year PFS rate could achieve 60% PFS by (FOLFOX + H101) over conventional HAIC (FOLFOX). Simon's two-stage design is used to estimate the sample size, with α value of 0.05 and power of 0.9. A total sample size of 66 participants are required.

  • Accompanied by any unstable systemic diseases, including but not limited to severe infection, resistant hypertension, unstable angina, stroke or myocardial infarction within 6 months, congestive heart failure, and serious cardiac arrhythmia requiring medication, renal or metabolic disease requiring medication
  • Known hypersensitivity to the study drug or oxaliplatin, leucovorin calcium, fluorouracil
  • History of immunodeficiency or autoimmune disease, or receiving long-term systemic steroid therapy within 7 days before enrollment, or any form of immunosuppressive therapy
  • Other conditions that are not suitable for participating in this trial
