Inclusion criteria

  • Histologically confirmed HER2-positive locally advanced or metastatic biliary tract cancer that has progressed after receipt of available therapies known to confer clinical benefit.
  • Adequate cardiac left ventricular function, as defined by left ventricular ejection fraction (LVEF) ≥ 50%
  • Adequate organ function
  • Ineligible to participate or has no access to an ongoing zanidatamab or other Zymeworks clinical study (e.g., ZW49 clinical study).
  • Females of childbearing potential and non-sterile males must agree to practice highly effective methods of birth control for the duration of the study and for 12 months after the last dose of study drug. In addition, non-sterile males must avoid sperm donation for the duration of the study and for 12 months after the last dose of study drug.

  • Systemic anti-cancer therapy ≤ 3 weeks before the first dose of zanidatamab.
  • Radiotherapy ≤ 2 weeks of the first dose of zanidatamab

The following central nervous system (CNS) brain lesions are excluded from the study:

  • Untreated or unstable brain lesions requiring immediate local therapy or symptomatic CNS metastases.
  • Radiation treatment for CNS metastases within 4 weeks before the first dose of zanidatamab.
  • Known history of or ongoing leptomeningeal disease (LMD). If LMD has been reported radiographically, but is not suspected clinically by the investigator, the patient must be free of neurological symptoms of LMD.

The following CNS brain lesions are permitted:

  • Stable brain lesions are permitted if stable, as defined by patients who are off steroids and anticonvulsants and are neurologically stable with no evidence of radiographic progression for at least 4 weeks at the time of screening.
  • Concurrent uncontrolled or active hepatobiliary disorders or untreated or ongoing complications after laparoscopic procedures or stent placement, including but not limited to active cholangitis, unresolved biliary obstruction, biloma or abscess. Any complications should be resolved within 2 weeks prior to the first dose of zanidatamab.
  • Active hepatitis
  • Infection with human immunodeficiency virus (HIV) with uncontrolled disease.
  • Females who are breastfeeding or pregnant, and females and males planning a pregnancy.
  • History of myocardial infarction or unstable angina within 6 months prior to enrollment, congestive heart failure (NYHA Class 3 or 4), or clinically significant cardiac disease
  • QTc Fridericia (QTcF) > 470 ms assessed within 30 days of screening
  • Acute or chronic uncontrolled pancreatitis or Child-Pugh Class C liver disease
