Study Overview
To test the effectiveness & safety of Zanidatamab (JZP598) with standard of care against standard of care alone as a first line treatment for Biliary Tract Cancer (including ICC, ECC, and gallbladder cancer) that contain extra HER2 protein on cancer cells. Patients must have HER2, advanced (unresectable) or metastatic biliary tract cancer.

Study Purpose
The purpose of this study is to evaluate the efficacy and safety of Zanidatamab plus CisGem (Cisplatin and Gemcitabine) with or without the addition of a programmed death protein 1/ligand-1 (PD-1/L1) inhibitor (physician's choice of either Durvalumab or Pembrolizumab, where approved under local regulations) as first line of treatment for participants with human epidermal growth factor receptor 2 (HER2)-positive biliary tract cancer.
Inclusion Criteria

  • Have diagnosed Biliary Tract Cancer (BTC) (Gallbladder Cancer (GBC), Intrahepatic Cholangiocarcinoma (ICC), or Extrahepatic Cholangiocarcinoma (ECC)).

  • Locally advanced unresectable or metastatic BTC and not eligible for curative resection, transplantation, or ablative therapies.

  • Received no more than 2 cycles of systemic therapy with gemcitabine and a platinum agent with or without your physician's choice of durvalumab or pembrolizumab, where approved under local regulations for advanced unresectable or metastatic disease.

  • HER2-positive disease (defined as IHC 3+; or IHC 2+/ ISH+) a central laboratory on new or archival tissue.

  • Radiographically assessable (by CT scan or MRI)

  • Male or female ≥ 18 years

  • Adequate organ function

  • Females of childbearing potential must have a negative pregnancy test result.

  • Females of childbearing potential and males with a partner of childbearing potential must be willing to use 2 methods of birth control.

Exclusion Criteria

  • Participation in another clinical trial with an investigational medicinal product within the last 3 months

  • Females who are breastfeeding

  • Any other medical, social, or psychosocial factors that, in the opinion of the investigator, could impact safety or compliance with study procedures

Required Tests Prior to Study

  • HER2 diagnostic test, which will be determined by your health care team

Potential Side Effects

  • Mild or moderate reactions related to the infusion

  • Mild or moderate (usually managed at home) diarrhea
