Maximum Observed Plasma Concentration (Cmax) of Intact AMG 133
Blood samples were collected at specific times during the study for the measurement of plasma concentrations of intact and total AMG 133 by a laboratory.
Time frame: Day 1 pre-dose and 24, 48, 72, 96, 120, 144, 168, 336, 504, 672, 1008, 1344, 1680, 2184, and 2856 hours post-dose
Cmax of Total AMG 133
Blood samples were collected at specific times during the study for the measurement of plasma concentrations of intact and total AMG 133 by a laboratory.
Time frame: Day 1 pre-dose and 24, 48, 72, 96, 120, 144, 168, 336, 504, 672, 1008, 1344, 1680, 2184, and 2856 hours post-dose
Area Under the Plasma Concentration-time Curve From Time Zero to the Time of Last Quantifiable Concentration (AUClast) of Intact AMG 133
Blood samples were collected at specific times during the study for the measurement of plasma concentrations of intact and total AMG 133 by a laboratory.
Time frame: Day 1 pre-dose and 24, 48, 72, 96, 120, 144, 168, 336, 504, 672, 1008, 1344, 1680, 2184, and 2856 hours post-dose

Time frame: Day 1 pre-dose and 24, 48, 72, 96, 120, 144, 168, 336, 504, 672, 1008, 1344, 1680, 2184, and 2856 hours post-dose
Area Under the Plasma Concentration-time Curve From Time Zero Extrapolated to Infinity (AUCinf) of Intact AMG 133
Blood samples were collected at specific times during the study for the measurement of plasma concentrations of intact and total AMG 133 by a laboratory.
Time frame: Day 1 pre-dose and 24, 48, 72, 96, 120, 144, 168, 336, 504, 672, 1008, 1344, 1680, 2184, and 2856 hours post-dose

Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE)
A TEAE was defined as any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with AMG 133 that started during or after dosing, or started prior to dosing and increased in severity after dosing. Clinically significant changes from baseline in clinical laboratory tests, 12-lead electrocardiograms (ECGs) and vital signs were also reported as TEAEs.
Time frame: Day 1 to Day 120
Number of Participants With a Positive Anti-AMG 133 Binding Antibody Result
Blood samples were collected at specific times during the study for the measurement of anti-AMG 133 binding antibodies from participants who received AMG 133.
Time frame: Days 1, 15, 29, 57 and 120
