1. Subjects with histologically- or cytologically-confirmed biliary tract cancer (including intrahepatic
cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gall bladder cancer)
2. HER2 positive biliary tract cancer (IHC 3+ or 2+ with ISH + (HER2/CEP17=2.0) or ERBB2 gene
copy number = 6.0 by NGS)
3. Age (at the time of informed consent): 20 years and older
4. Previously untreated if unresectable/metastatic at initial diagnosis; or recurrent disease >6 months after
curative surgery or adjuvant therapy (allow up to 1 cycle of gemcitabine-based chemotherapy for
advanced/unresectable or metastatic cholangiocarcinoma prior to enrollment)
5. Explicit and voluntary consent to participate in the study obtained using a signed and dated informed
consent form clearly and fully describing the purpose, potential risks, and any other critical issues
regarding the study.
6. Subject with measurable lesions according to RECIST v. 1.1
7. ECOG Performance Status Score 0 or 1
8. Patients with a life expectancy of at least 3 months
9. Patients whose latest laboratory data meet the below criteria within 14 days before enrollment. If the
date of the laboratory tests at the time of screening is not within 7 days before the first dose of the
investigational product, testing must be repeated within 7 days before the first dose of the
investigational product, and these latest laboratory tests must meet the following criteria. Of note,
laboratory data will not be valid if the patient has received a granulocyte colony-stimulating factor (GCSF)
or blood transfusion within 14 days before testing.
• White blood cells =2,000/mm3 and neutrophils =1,500/mm3
• Platelets =100,000/mm3
• Hemoglobin =9.0 g/dL
• AST (GOT) and ALT (GPT) =3.0-fold the upper limit of normal (ULN) of the study site (or =5.0-
fold the ULN of the study site in patients with liver metastases)
• Total bilirubin =1.5-fold the ULN of the study site
• Creatinine =1.5-fold the ULN of the study site or creatinine clearance (either the measured or
estimated value using the Cockcroft-Gault equation) >45 mL/min
• INR =1.5-fold or prothrombin time =1.5-fold the ULN of the study site
• aPTT =1.5-fold the ULN of the study site
10. Women of childbearing potential (including women with chemical menopause or no menstruation for
other medical reasons) #1 must agree to use contraception#2 from the time of informed consent until 5
months or more after the last dose of the investigational product. Also, women must agree not to
breastfeed from the time of informed consent until 5 months or more after the last dose of the
investigational product.
11. Men must agree to use contraception#2 from the start of study treatment until 7 months or more after
the last dose of the investigational product. #1. Women of childbearing potential are defined as all women after the onset of menstruation who are
not postmenopausal and have not been surgically sterilized (e.g., hysterectomy, bilateral tubal ligation,
bilateral oophorectomy). Postmenopause is defined as amenorrhea for =12 consecutive months without
specific reasons. Women using oral contraceptives, intrauterine devices, or mechanical contraception
such as contraceptive barriers are regarded as having childbearing potential.
#2. The subject must consent to use any of the following methods of contraception: vasectomy or
condom for patients who ar
1. Patients treated with systemic chemotherapy, biologic therapy, immunotherapy, hormone therapy, or
clinical trials for unresectable, locally advanced or metastatic biliary tract cancer. However, the
following are excluded.
a. If disease recurrence occurs 6 months after the last dose of adjuvant chemotherapy, previous
adjuvant chemotherapy is permitted.
b. 1 cycle of Gemcitabine-based anticancer therapy for locally advanced or metastatic
cholangiocarcinoma prior to enrollment in this trial is permitted.
2. Patients with multiple primary cancers (with the exception of completely resected basal cell
carcinoma, stage I squamous cell carcinoma, carcinoma in situ, intramucosal carcinoma, or superficial
bladder cancer, or any other cancer that has not recurred for at least 5 years)
3. Patients with residual adverse effects of prior therapy or effects of surgery that would affect the safety
evaluation of the investigational product in the opinion of the investigator or sub-investigator.
4. Patients with current or past history of severe hypersensitivity to any other antibody products
5. Patients with concurrent autoimmune disease or history of chronic or recurrent autoimmune disease
6. Patients with a current or past history of interstitial lung disease or pulmonary fibrosis diagnosed based
on imaging or clinical findings. Patients with radiation pneumonitis may be enrolled if the radiation
pneumonitis has been confirmed as stable (beyond acute phase) without any concerns about
recurrence.
7. Patients with concurrent diverticulitis or symptomatic gastrointestinal ulcerative disease
8. Patients with any metastasis in the brain or meninx that is symptomatic or requires treatment. Patients
may be enrolled if the metastasis is asymptomatic and requires no treatment.
9. Patients with pericardial fluid, pleural effusion, or ascites requiring treatment
10. Patients with uncontrollable, tumor-related pain
11. Patients who have experienced a transient ischemic attack or cerebrovascular accident within 180 days
before enrollment
12. Patients with a history of uncontrollable or significant cardiovascular disease meeting any of the
following criteria:
? Myocardial infarction within 180 days before enrollment
? Uncontrollable angina pectoris within 180 days before enrollment ? New York Heart Association (NYHA) Class III or IV congestive heart failure
? Uncontrollable hypertension despite appropriate treatment (e.g., systolic blood pressure =150
mmHg or diastolic blood pressure = 90 mmHg lasting 24 hours or more)
? Arrhythmia requiring treatment
13. Patients with uncontrollable diabetes mellitus
14. Patients with systemic infections requiring treatment (infection controlled by oral antibiotics is
permitted)
15. Patients who have received systemic corticosteroids (prednisolone or equivalent > 10mg/day) (except
for temporary use, e.g., for examination or prophylaxis of allergic reactions) or immunosuppressants
within 28 days before enrollment
16. Patients who have received antineoplastic drugs (e.g., chemotherapy agents, molecular-targeted
therapy agents, or immunotherapy agents) within 28 days before enrollment
17. Patients who have undergone surgical adhesion of the pleura or pericardium within 28 days before
enrollment
18. Patients who have undergone surgery under general anesthesia within 28 days before enrollment
19. Patients who have undergone surgery involving loc
