Trial Outcomes & Findings for Multiple Ascending Dose Study of AMG 598 in Adults With Obesity (NCT NCT03757130)

NCT ID: NCT03757130

Last Updated: 2023-09-14

Results Overview

The investigator assessed the severity of each adverse event reported during the study. The assessment was based on the Amgen Standard Grading Scale: Mild: Aware of sign or symptom, but easily tolerated. Moderate: Discomfort enough to cause interference with usual activity. Severe: Incapacitating with inability to work or do usual activity. A Serious adverse event is defined as any untoward medical occurrence that, met at least 1 of the following serious criteria * Death; * Was life-threatening; * Required in-patient hospitalization or prolongation of existing hospitalization; * Resulted in persistent or significant disability/incapacity; * Was a congenital anomaly/birth defect; * Other medically important serious event. The investigator also assessed whether each adverse event was related to study drug administration based on clinical judgement.

PRIMARY outcome

Timeframe: 207 days

Population: All participants who received at least 1 dose of study drug (AMG 598 or placebo) on day 1.

The investigator assessed the severity of each adverse event reported during the study. The assessment was based on the Amgen Standard Grading Scale: Mild: Aware of sign or symptom, but easily tolerated. Moderate: Discomfort enough to cause interference with usual activity. Severe: Incapacitating with inability to work or do usual activity. A Serious adverse event is defined as any untoward medical occurrence that, met at least 1 of the following serious criteria * Death; * Was life-threatening; * Required in-patient hospitalization or prolongation of existing hospitalization; * Resulted in persistent or significant disability/incapacity; * Was a congenital anomaly/birth defect; * Other medically important serious event. The investigator also assessed whether each adverse event was related to study drug administration based on clinical judgement.

Population: All participants who received at least 1 dose of study drug (AMG 598 or placebo) on day 1.

TEAEs due to laboratory, electrocardiogram (ECG) and vital sign findings include any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or electrocardiogram, or vital signs measurements, including those that worsened from baseline, that were considered clinically significant in the medical and scientific judgment of the investigator (ie, not related to progression of underlying disease).

SECONDARY outcome

Timeframe: Day 1, predose, and days 6, 8, 15, 22, and 29; Day 57 predose and days 62, 64, 71, 85, 99, 113, 127, 169, and 207

Population: The pharmacokinetic (PK) analysis set included all participants for whom at least 1 PK parameter or endpoint could be adequately estimated. Participants with available data at each time point.

Serum concentrations of AMG 598 were determined using a validated electrochemiluminescence-based method. The lower limit of quantitation was 50.0 ng/mL.

Results disclosure agreements

  • Principal investigator is a sponsor employee The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
