What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Who Experienced Treatment-Emergent Adverse Events (TEAEs)
An adverse event (AE) was any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with study treatment. A serious AE (SAE) was an AE meeting at least 1 of the following serious criteria: fatal, life-threatening, required in-patient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability; congenital anomaly/birth defect; other medically important serious event. Clinically significant changes from baseline in laboratory safety tests, vital sign assessments, and 12-lead electrocardiogram assessments were included as TEAEs.
Measured: From first dose of IP to end of study, up to Day 207
Secondary outcomes (8)
Maximum Observed Serum Concentration (Cmax) for AMG 171: SAD Cohorts 1 and 1b
Serum concentrations of AMG 171 were determined using a validated assay. Noncompartmental analysis was performed for estimation of pharmacokinetic (PK) parameters. Concentrations below the lower limit of quantification (LLOQ) (50.0 ng/mL) were set to zero before data analysis.
Measured: Cohorts 1 and 1b: pre-dose Day 1; 1, 2, 4, and 8 hours post-dose Day 1, Days 2 up to Day 120
Cmax for AMG 171: MAD Cohorts 2 - 5
Serum concentrations of AMG 171 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ (50.0 ng/mL) were set to zero before data analysis.
Measured: Cohort 2: pre-dose Days 1, 15, 29, 43, 57, 71; post-dose Days 5 up to 207; Cohort 3: pre-dose Days 1, 15; post-dose Days 2 up to 85; Cohort 4: pre-dose Days 1, 15, 29; post-dose Days 2 up to 113; Cohort 5: pre-dose Days 1, 8; post-dose Days 2 up to 85
Time of Cmax (Tmax) for AMG 171: SAD Cohorts 1 and 1b

Measured: Cohorts 1 and 1b: pre-dose Day 1; 1, 2, 4, and 8 hours post-dose Day 1, Days 2 up to Day 120
Tmax for AMG 171: MAD Cohorts 2 - 5
Serum concentrations of AMG 171 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ (50.0 ng/mL) were set to zero before data analysis.
Measured: Cohort 2: pre-dose Days 1, 15, 29, 43, 57, 71; post-dose Days 5 up to 207; Cohort 3: pre-dose Days 1, 15; post-dose Days 2 up to 85; Cohort 4: pre-dose Days 1, 15, 29; post-dose Days 2 up to 113; Cohort 5: pre-dose Days 1, 8; post-dose Days 2 up to 85
Area Under the Plasma Concentration-time Curve (AUC) From Time 0 to Infinity (AUCinf) for AMG 171: SAD Cohorts 1 and 1b
Serum concentrations of AMG 171 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ (50.0 ng/mL) were set to zero before data analysis.

Serum samples were tested for binding and neutralizing antibodies against human Growth Differentiation Factor 15. Participants with transiently positive for binding or neutralizing antibodies had a negative result at the participant's last time point tested.
bAb = binding antibody; nAb = neutralizing antibody; +ve = positive; -ve = negative; BL = baseline.
Measured: Cohorts 1 and 1b: Day 1 pre-dose, Days 15, 29, 120; Cohort 2: Days 1, 29, 57 pre-dose, Days 15, 85, 207; Cohort 3: Days 1, 15 pre-dose, Days 29, 57, 85; Cohort 4: Days 1, 15, 29 pre-dose, Days 43, 85, 113; Cohort 5: Days 1, 8 pre-dose, Days 29, 57, 85

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AMG 171 in people with Obesity, run by Amgen at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 19 Sep 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants Who Experienced Treatment-Emergent Adverse Events (TEAEs) (time frame: From first dose of IP to end of study, up to Day 207). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024.
