Locally Advanced Intrahepatic Cholangiocarcinoma

This phase II trial tests how well giving gemcitabine, cisplatin and durvalumab alternating with pemigatinib for the treatment of biliary tract cancer with FGFR2 alterations that cannot be removed by surgery (unresectable), that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill cancer cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pemigatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal FGFR protein that signals cancer cells to multiply. This may help keep cancer cells from growing and may kill them. Giving gemcitabine, cisplatin and durvalumab alternating with pemigatinib may work well for the treatment of unresectable, locally advanced or metastatic biliary tract cancer with FGFR2 alterations.

This phase II/III trial studies how well the addition of ivonescimab to standard chemotherapy (gemcitabine and cisplatin) works when compared to usual chemotherapy and immunotherapy (durvalumab or pembrolizumab) in treating patients with biliary tract cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill tumor cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Immunotherapy with monoclonal antibodies, such as durvalumab and pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ivonescimab is a bispecific antibody that is directed against both the programmed cell death protein 1 (PD-1) and vascular endothelial growth factor (VEGF) protein. By targeting PD-1, ivonescimab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. By targeting VEGF, ivonescimab may help stop the formation of blood vessels that bring oxygen and nutrients to tumor. Adding ivonescimab to standard chemotherapy may work better than usual chemotherapy and immunotherapy in lowering the chance of advanced biliary tract cancer growing or spreading.

This phase I trial tests the safety and side effects of yttrium-90 (Y90) radioembolization combined with immunotherapy drugs tremelimumab and durvalumab in treating patients with intrahepatic cholangiocarcinoma (cancer of the bile ducts in the liver) that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable) who are not candidates for curative therapy or that has spread from where it first started (primary side) to multiple other places in the body (oligo-metastatic). Cholangiocarcinoma is a rare but aggressive cancer with limited curative options outside of surgery. Immunotherapy has shown modest benefit in hepatobiliary (liver, bile ducts, and gallbladder) cancers including cholangiocarcinoma. Radioembolization is a type of radiation therapy used to treat liver cancer that is advanced or has come back where tiny beads that hold the radioactive substance (radioisotope) yttrium Y90 are injected into or near the hepatic artery (the main blood vessel that carries blood to the liver). The beads collect in the tumor and the Y90 gives off radiation. This destroys the blood vessels that the tumor needs to grow and kills the tumor cells. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving Y90 radioembolization in combination with tremelimumab and durvalumab immunotherapy may be safe and beneficial in treating patients with locally advanced, unresectable or oligo-metastatic intrahepatic cholangiocarcinoma who are not candidates for curative therapy.

The study hypothesis is that liver transplantation after selective internal radiation therapy (SIRT) and chemotherapy would improve 3-year overall survival in patients with locally advanced (unresectable but non-metastatic) intrahepatic cholangiocarcinoma. It is planned to include 36 patients with locally advanced intrahepatic cholangiocarcinoma, not eligible for initial surgery and without metastases. Participants will be recruited from care facilities in France.
