To evaluate the safety and tolerability of AMG 199 in adult subjects and to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D).
Full description
AMG 199 is a novel half-life extended (HLE) bispecific T cell engager (BiTE®) molecule designed to direct T cells towards MUC17-expressing cells. This is a first-in-human study in adult subjects with MUC17-positive solid tumors including gastric cancer, gastroesophageal junction (GEJ), colorectal, and pancreatic cancers, collectively referred to as "solid tumors" in this clinical investigation to assess AMG 199 safety, tolerability, pharmacokinetics (PK), and anti-tumor activity, with additional exploratory objectives to assess pharmacodynamics (PD), correlative biomarker analysis, and immunogenicity.
The primary end point is to evaluate the safety and tolerability of AMG 199 in adult subjects, and determine the MTD and RP2D. The secondary end point is characterize the PK and anti-tumor activity of AMG 199.

Inclusion criteria
Key Inclusion Criteria:
• Subjects with histologically or cytologically confirmed metastatic or locally advanced unresectable gastric adenocarcinoma or gastroesophageal junction (GEJ) adenocarcinoma positive for MUC17. 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 colorectal cancer positive for MUC17. 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).
