Number of Participants With Dose-Limiting Toxicities (DLTs)Primary· 28 days
A DLT was defined as any of the following occurring during the first 28 days of treatment and regarded by the investigator and/or sponsor as related to AMG 211. Hematological DLTs: absolute neutrophil count (ANC) \< 0.5 × 10⁹ cells/L for ≥ 7 days; febrile neutropenia (fever of unknown origin without clinically or microbiologically documented infection) with ANC \< 0.5 × 10⁹ cells/L and fever ≥ 38.5°C; platelets \< 25 × 10⁹ cells/L ≥ 7 days. Non-hematological DLTs: any AMG 211-related ≥ grade 3 non-hematological toxicity, excluding nausea and vomiting not refractory to anti-emetics, flare-up of

Maximum Observed Concentration (Cmax) of AMG 211 in Cycle 1 in Participants Who Received Dosing for 7 or 14 DaysSecondary· Cycle 1: Predose, 2, 6, 24, 48-96, and 168 (for 14-day dosing groups only) hours after the start of infusion, at the end of infusion (Day 8 or Day 15), and 0.5, 2, 4, 8, and 24 hours after the end of infusion.
Levels of AMG 211 in plasma samples collected during this study were analyzed using an electrochemiluminiscence assay. The lower limit of quantification (LLOQ) of the assay was 0.10 ng/mL.

Number of Participants With Treatment Emergent Adverse Events (TEAEs)Primary· From first dose of study drug through end of treatment + 30 days (median time frame was 75.5 days).
An adverse event (AE) was defined as any untoward medical occurrence, which does not necessarily have a causal relationship with study treatment. A serious adverse event (SAE) was defined as an event that: was fatal or life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/borth defect; or other significant medical event. A TEAE was defined as any AE starting on or after the first dose of study drug and up to and including 30 days after the end of last dose of study

The purpose of this Phase 1 study is to determine if AMG 211 given as a continous intravenous (IV) infusion is safe and tolerable in adult participants that have advanced gastrointestinal adenocarcinoma. The study will be conducted in multiple sites and test increasing doses of AMG 211. The safety of participants will be monitored by intensive assessment of vital signs, electrocardiograms, physical examinations, and laboratory tests. Efficacy will be assessed by the usual imaging procedures and their interpretation.
