To Evaluate IAH0968 in Combination With CAPEOX in HER2-positive Gastric Cancer
Trial Parameters
Brief Summary
The safety, tolerability, and determination of the maximum tolerated dose (MTD) of the combination therapy were first evaluated for IAH0968 in combination with or without the CAPEOX regimen in unsystematically treated subjects with HER2-expressing advanced/metastatic colorectal or gastric cancers (including adenocarcinomas of the gastro-esophageal junction) or HER2-hypo-expressing advanced/metastatic solid tumors. The efficacy of IAH0968 in combination with the CAPEOX regimen versus trastuzumab in combination with the CAPEOX regimen in subjects with HER2-positive advanced/metastatic gastric cancer, including gastro-esophageal junction adenocarcinoma, was then assessed by progression-free survival (PFS) according to the Research and Evaluation Criteria for the Evaluation of Efficacy in Solid Tumors (RECIST) 1.1.
Eligibility Criteria
Inclusion Criteria: * 1\) Age 18\~75 years old (including critical mass), gender is not limited. 2) Phase II cohort 1 and III only: patients with locally advanced or metastatic gastric cancer (including adenocarcinoma of the gastro-esophageal junction) diagnosed by histopathology, unsuitable for radical surgical resection or localized treatment, and who have not received systemic antitumor therapy (including systemic chemotherapy, molecularly-targeted drug therapy, biologic therapy, and other investigational therapeutic agents) for GC (except for adjuvant chemotherapy for \>6 months), and who have demonstrated disease progression; and patients who have been diagnosed by immunohistochemistry (IHC) staining and/or fluorescence in situ hybridization (FISH). and demonstrated disease progression excepted); HER2 positivity (IHC 3+, or IHC 2+ and FISH +) demonstrated by immunohistochemical (IHC) staining and/or fluorescence in situ hybridization (FISH). 3\) Phase II Cohort 2 only: Have histol
