Single Ascending Dose Study of AMG 570 in Healthy Subjects

Phase 1

Completed

• Conditions: Systemic Lupus Erythematosus

• Registration Number: NCT02618967
• Lead Sponsor: Amgen

Brief Summary

The purpose of this study is to obtain initial information on the safety and tolerability (effects good or bad), pharmacokinetics (what the body does to the drug), and pharmacodynamics (what the drug does to the body) of a single dose of AMG 570.

Primary Outcome Measures

Name	Time	Method
Number of Participants Who Experienced One or More Treatment-emergent Adverse Events (TEAEs)	Day 1 to Day 105	TEAEs were adverse events with an onset after the administration of study treatment.; TEAEs were graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.; Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limited age appropriate instrumental activities of daily life (ADL).; Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolonged hospitalization indicated; disabling; limited self care ADL.; Grade 4 Life-threatening consequences; urgent interventions indicated.; Serious adverse events (SAEs) were defined as meeting at least 1 of the following criteria: * Results in death (fatal); * Immediately life-threatening; * Requires in-patient hospitalization or prolongation of existing hospitalization; * Results in persistent or significant disability/incapacity; * Is a congenital anomaly/birth defect; * Other medically important serious event
Number of Participants Who Experienced a Clinically Significant Change in Physical Examinations	Baseline to Day 105	Physical examinations were performed by the investigator, designated physician, or nurse practitioner. A complete physical examination included, at a minimum, assessment of cardiovascular, respiratory, gastrointestinal and neurological systems. A brief physical examination included assessment of the skin, lungs, cardiovascular system, and abdomen (liver and spleen).
Number of Participants Who Experienced a Clinically Significant Change in Vital Signs	Baseline to Day 105	Any changes in blood pressure, body temperature, heart rate, and pulse rate that were deemed as clinically significant by the Investigator were reported.
Number of Participants Who Experienced a Clinically Significant Change in Clinical Laboratory Safety Tests	Baseline to Day 105	Laboratory safety tests included chemistry, hematology, and urinalysis parameters. Clinically significant laboratory safety tests were any events assessed as CTCAE Grade ≥3 at any post-baseline visit.; Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolonged hospitalization indicated; disabling; limited self care ADL.; Grade 4 Life-threatening consequences; urgent interventions indicated.
Number of Participants Who Experienced a Clinically Significant Change in Electrocardiograms (ECGs)	Baseline to Day 105	Any changes in ECG parameters that were deemed clinically significant by the Investigator were reported.

Secondary Outcome Measures

Name	Time	Method
Maximum Observed Concentration (Cmax) of AMG 570	Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105	AMG 570 pharmacokinetic (PK) parameters were estimated using non-compartmental analysis.
Number of Participants With an Anti-AMG 570 Binding Antibody Positive Postbaseline Result	Baseline to Day 105	The presence of anti-AMG 570 binding antibodies was assessed using a validated assay. The number and percentage of participants who developed binding anti-AMG 570 antibodies at any postbaseline visit are presented.
Time to Reach Maximum Observed Concentration (Tmax) of AMG 570	Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105	AMG 570 PK parameters were estimated using non-compartmental analysis.
Area Under the Concentration-time Curve From Time 0 to Time of the Last Quantifiable Concentration (AUClast) of AMG 570	Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105	AMG 570 PK parameters were estimated using non-compartmental analysis.
Area Under the Concentration-time Curve Observed From Time Zero to Infinity (AUCinf) of AMG 570	Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105
Percentage Change From Baseline for CD19+ Total B Cells Percentages (%)	Baseline to Day 8; Day 29; Day 57 and Day 105
Mean Peripheral Blood B7-Related Protein-1 (B7RP-1) Receptor Occupancy on Total B Cells	Day 8; Day 29; Day 57; and Day 105	Peripheral B7RP1 (also known as inducible costimulator ligand \[ICOSL\]) receptor occupancy was calculated from the free ICOSL and total ICOSL measurement from B cells in whole blood.
Percentage Change From Baseline for Cluster of Differentiation (CD)19+ Total B Cells Counts	Baseline to Day 8; Day 29; Day 57 and Day 105
