Ivosidenib (AG-120) With Nivolumab in IDH1 Mutant Tumors

We have identified IDH1 mutations as mediating the exclusion of immune cells in tumors. Ivosidenib is an IDH1 inhibitor. We hypothesize that blocking IDH1 will enhance cancer immunotherapy (nivolumab) in settings where immunotherapy normally doesn’t work. Approximately 10-15% of patients with cholangiocarcinomas have tumors with IDH1 mutations.

Durvalumab or Placebo in Combination With Gemcitabine/Cisplatin in Patients With 1st Line Advanced Biliary Tract Cancer (TOPAZ-1) (TOPAZ-1)

This is a Phase III Study of Durvalumab (Immunotherapy) in Combination With Gemcitabine Plus Cisplatin Versus Placebo in Combination With Gemcitabine Plus Cisplatin for Patients With First-Line Advanced Biliary Tract Cancers. Chemotherapy (Gemcitabine plus Cisplatin) is the standard of care for advanced biliary tract cancer.

A Phase 2 Study to Evaluate the Efficacy and Safety of Adoptive Transfer of Autologous Tumor Infiltrating Lymphocytes in Patients with Locally Advanced, Recurrent, or Metastatic Biliary Tract Cancers

This Phase 2 study will be conducted in conjunction with the companion harvest protocol protocol in patients with measurable disease who have lesions that can be resected or biopsied for Tumor Infiltrating Lymphocyte(TIL) growth. The Treatment Phase begins once the cells exceed the cell growth and potency requirements in the companion protocol.

Immunotherapy of Cholangiocarcinoma

Earlier version of immunotherapy, which was designed for patients with hepatocellular carcinoma (HCC) has shown limited efficacy in patients with cholangiocarcinoma (CCA). The decline in levels of CA19.9 marker common in CCA correlated with tumor shrinkage.
