Outcome Measures
Primary Outcomes (2)
Number of Participants With Treatment-emergent Adverse Events
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.
207 days
Number of Participants With TEAEs Due to Laboratory, Electrocardiogram, and Vital Sign Findings
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).

AMG 598 70 mg + Liraglutide
EXPERIMENTALParticipants received 70 mg AMG 598 by subcutaneous injection once every 4 weeks for a total of 3 doses in addition liraglutide administered by subcutaneous injection once a day for 12 weeks. The starting dose of liraglutide was 0.6 mg/day, increasing in increments of 0.6 mg/day every 7 days to reach the full dosage of 3 mg/day by week 5.
AMG 598 210 mg
EXPERIMENTALParticipants received 210 mg AMG 598 by subcutaneous injection once every 4 weeks for a total of 3 doses.
AMG 598 210 mg + Liraglutide
EXPERIMENTALParticipants received 210 mg AMG 598 by subcutaneous injection once every 4 weeks for a total of 3 doses in addition to liraglutide administered by subcutaneous injection once a day for 12 weeks. The starting dose of liraglutide was 0.6 mg/day, increasing in increments of 0.6 mg/day every 7 days to reach the full dosage of 3 mg/day by week 5.
AMG 598 420 mg
EXPERIMENTALParticipants received 420 mg AMG 598 by subcutaneous injection once every 4 weeks for a total of 3 doses.
AMG 598 420 mg + Liraglutide
EXPERIMENTALParticipants received 420 mg AMG 598 by subcutaneous injection once every 4 weeks for a total of 3 doses in addition to liraglutide administered by subcutaneous injection once a day for 12 weeks. The starting dose of liraglutide was 0.6 mg/day, increasing in increments of 0.6 mg/day every 7 days to reach the full dosage of 3 mg/day by week 5.
Interventions
AMG 598 administered by subcutaneous injection
Placebo matching to AMG 598 administered by subcutaneous injection
Liraglutide administered by subcutaneous injection. The starting dose is 0.6 mg/day, and increased by 0.6 mg/day dose increment every 7 days, up to the full dosage of 3.0 mg/day by week 5.

In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications. Further details are available at the link below.
