简要总结
Compare the efficacy of zanidatamab plus cisplatin plus gemcitabine (CisGem) with or without a programmed cell death 1 (PD-1) or programmed cell death ligand 1 (PDL1) inhibitor (PD-1/L1 inhibitor) versus CisGem with or without a PD1/L1inhibitor in participants with advanced or metastatic human epidermal growth factor receptor 2 (HER2)-positive (IHC 3+) biliary tract cancer (BTC)

入选标准
- •Histologically- or cytologically-confirmed BTC, including GBC, ICC, or ECC.
- •Locally advanced unresectable or metastatic BTC and not eligible for curative resection, transplantation, or ablative therapies. 3 . Received no more than 2 cycles of systemic therapy which is limited to CisGem with or without a PD-1/L1 inhibitor (physician’s choice of durvalumab or pembrolizumab, where approved under local regulations) for advanced unresectable or metastatic disease. Participants who have received prior adjuvant or neoadjuvant treatment (including investigational products) for earlier stage disease are permitted as long as therapy was completed more than 6 months prior to expected date of C1D
- •HER2-positive disease (defined as IHC 3+; or IHC 2+/ ISH+) by IHC and ISH assay (in participants with IHC 2+ tumors) at a central laboratory on new biopsy tissue or archival tissue from the most recent biopsy (See Section 7.1). Note that fine needle aspirates (FNAs; which obtain only cytology samples), cytology samples, brushings, and biopsies from sites of bone metastases are not acceptable. Biopsies obtained with a needle that provides intact tissue sample may be acceptable. Testing may occur with tissue obtained at any time after diagnosis of BTC and before randomization.
