Inclusion Criteria

  • 103 - Subjects with histologically or cytologically confirmed metastatic or
  • locally advanced gastric adenocarcinoma or GEJ adenocarcinoma positive for
  • MUC17 as defined by the test described herein. Subjects should have been
  • refractory to or have relapsed after two or more prior lines of standard
  • systemic therapy that included a platinum, a fluoropyrimidine, nivolumab (in
  • combination with a platinum and a fluoropyrimidine), either a taxane or
  • irinotecan, and an approved vascular endothelial growth factor receptor (VEGFR)
  • antibody/tyrosine kinase inhibitor (TKI).
  • OR Subjects with histologically or cytologically confirmed metastatic or
  • locally advanced unresectable CRC positive for MUC17 as defined by the test
  • described herein. Subjects should have been refractory
  • to or have relapsed after at least two and up to five prior lines of standard
  • systemic therapy. Therapy should have included an approved vascular endothelial
  • growth factor (VEGF) antibody (if clinically appropriate) and epidermal growth
  • factor receptor (EGFR) antibody (if kirsten rat sarcoma
  • (KRAS)/ neuroblastoma RAS viral oncogene homolog (NRAS)/ v-Raf murine sarcoma
  • viral oncogene homolog B1 (BRAF) wild type tumor).
  • OR Subjects with histologically or cytologically confirmed unresectable or
  • metastatic pancreatic ductal adenocarcinoma positive for MUC17 as defined by
  • the test described herein. Subjects should have been refractory to or have
  • relapsed after at least one and up to three prior lines of standard systemic
  • 104 - Gastric adenocarcinoma and GEJ adenocarcinoma: Subjects eligible for
  • human epidermal growth factor receptor 2 (HER2) directed therapy, prior
  • systemic therapy should have included a HER2 targeting antibody approved for
  • treatment of gastric cancer. For Subjects with microsatellite instability high
  • (MSI H) or mismatch repair deficient (dMMR) tumors a prior line of treatment
  • should have included an approved PD-1-blocking antibody.
  • 105 - Subjects may also be included if the aforementioned therapeutic options
  • were medically not appropriate for them.
  • 106 - For dose-expansion only: Subjects with at least one measurable lesion >=
  • 10mm which has not undergone biopsy within 3 months of screening scan. This
  • lesion cannot be biopsied at any time during the study.
  • Refer to section 5.1 of the protocol.

Exclusion Criteria

  • Any anticancer therapy or immunotherapy within 4 weeks of start of first dose.
  • Central nervous system (CNS) metastases, leptomeningeal, or spinal cord
  • compression.
  • Autoimmune disorders requiring chronic systemic steroid therapy or any other
  • form of immunosuppressive therapy. Subjects may be included if the treatment
  • is discontinued more than 3 months prior to the first dose of AMG 199, there is
  • a low likelihood of relapse from the autoimmune disorder, AND there is
  • agreement between the investigator and the Amgen Medical Monitor.
  • Refer to 5.2 of the protocol.
