Comparing 3 approaches for biliary tract cancer

Exclusion

• −Active primary immunodeficiency, known uncontrolled active HIV infection or HCV.
• −Prior exposure to other HER2 targeting therapies, ADCs, immune checkpoint inhibitors and therapeutic anticancer vaccines.
• −Histologically confirmed ampullary carcinoma.
• −Any other medical conditions such as clinically significant cardiac or psychological conditions, that may, in the opinion of the InvestigatorPrincipal investigatorThe doctor or researcher responsible for running the study at a site.Read more →, interfere with the patient's participation in the clinical study or evaluation of the clinical study results.
• −Spinal cord compression or clinically active central nervous system metastases, defined as untreated and symptomatic, or requiring therapy with corticosteroids or anticonvulsants to controlControl groupThe group a new treatment is measured against.Read more → associated symptoms.
• −Medical history of myocardial infarction within 6 months before randomizationRandomisedWhich group you go into is decided by chance, not by you or your doctor.Read more →/enrollmentEnrolmentThe number of participants a study plans to include, or has included.Read more →, symptomatic congestive heart failure (New York Heart Association Class II to IV), unstable angina pectoris, clinically important cardiac arrhythmias, or a recent (\< 6 months) cardiovascular event including stroke.
• −Serious chronic gastrointestinal conditions associated with diarrhea (eg, active inflammatory bowel disease); active non-infectious skin disease (including any grade rash, urticaria, dermatitis, ulceration, or psoriasis) requiring systemic treatment.
• −Active autoimmune, connective tissue or inflammatory disorders that has required systemic treatment in the past 2 years, or where there is documented, or a suspicion of pulmonary involvement at the time of screeningScreeningThe checks done before joining, to see whether a study fits.Read more →.
• −Corrected QT interval (QTcF) prolongation to \> 470 msec (females) or \> 450 msec (males) based on average of the screening triplicate 12-lead ECG.
• −History of (non-infectious) ILD/pneumonitis, has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening.
• −Lung-specific intercurrent clinically significant illnesses including, but not limited to, any underlying pulmonary disorder (eg, pulmonary emboli within three months of the study enrollment, severe asthma, severe chronic obstructive pulmonary disease, restrictive lung disease, pleural effusion etc).
• −Prior pneumonectomy (complete).
• −Uncontrolled infection requiring IV antibiotics, antivirals, or antifungals. Patients with prior cholangitis/biliary tract infections/biliary intervention (eg, stent, external drain) should have completed a full course of antibiotics prior to randomization.
• −History of another primary malignancy except for malignancy treated with curative intent with no known active disease within 3 years before the first dose of study intervention and of low potential risk for recurrence. Exceptions include adequately resected nonmelanoma skin cancer and curatively treated in situ disease. For certain participant populations, exceptions could also include carcinomas in-situ or Ta tumors treated with curative intent.
• −Pleural effusion, ascites or pericardial effusion that requires drainage, peritoneal shunt, or Cell-free and Concentrated Ascites Reinfusion Therapy (Drainage and Cell free and Concentrated Ascites Reinfusion Therapy are not allowed within 2 weeks prior to screening assessment).
• −Any concurrent anticancer treatment without an adequate washout periodWashout periodA gap with no treatment, so the previous one clears your system.Read more → prior to randomization. Concurrent use of hormonal therapy for non-cancer related conditions (eg, hormone replacement therapy) is allowed.
• −History of organ transplants or allogenic stem cell transplant.
