Design outcomes

Primary

MeasureTime frame
Main Objective: To compare and assess the dose-response of 3 selected doses of AMG 133 compared with placebo, on inducing and maintaining weight loss from baseline at week 52 in subjects with overweight or obesity without diabetes mellitus (cohort A) and in subjects with overweight or obesity with type 2 diabetes mellitus (cohort B).;Secondary Objective: Key Secondary • To evaluate the effect of AMG 133 on achieving specific categories of body weight loss from baseline at week 52 in cohorts A and B • To evaluate the effect of AMG 133 on glucose metabolism in cohorts A and B • To characterize the pharmacokinetics (PK) properties of AMG 133 Secondary • To evaluate the effect of AMG 133 on waist circumference • To assess the treatment effect of dose-escalation regimens • To evaluate the effect of AMG 133 on systolic blood pressure (SBP) • To evaluate the effect of AMG 133 on diastolic blood pressure (DBP) • To evaluate the effect of AMG 133 on body composition in a subpopulation • To evaluate the effect of AMG 133 on a marker of inflammation • To evaluate the effect of AMG 133 on body mass index (BMI) • To evaluate the effect of AMG 133 on lipid parameters;Primary end point(s): •Percent change from baseline to week 52 in body weight ;Timepoint(s) of evaluation of this end point: From baseline to week 52

Secondary

MeasureTime frame
Secondary end point(s): Key Secondary: • Achieving = 5% reduction in body weight from baseline at week 52 (yes/no) • Achieving = 10% reduction in body weight from baseline at week 52 (yes/no) • Achieving = 15% reduction in body weight from baseline at week 52 (yes/no) • Achieving = 20% reduction in body weight from baseline at week 52 (yes/no) • Change from baseline to week 52 in hemoglobin A1c (HbA1c) (%, mmol/mol) • Change from baseline to week 52 in fasting serum insulin • Change from baseline to week 52 in fasting plasma glucose • Change from baseline to week 52 in Homeostasis Model Assessment for insulin resistance (HOMA2-IR) • Change from baseline to week 52 in Homeostasis Model Assessment for steady state beta cell function (HOMA2-%B) • PK parameters for AMG 133 including, but not limited to maximum observed plasma concentration (Cmax), and area under the concentration-time curve (AUC) Secondary • Change from baseline to week 52 in waist circumference • Change from baseline to week 52 in body weight • Change from baseline to week 52 in SBP • Change from baseline to week 52 in DBP • Change from baseline to week 52 in body composition (eg, fat mass, lean mass) using dual energy X ray absorptiometry (DXA) for a subset of subjects • Percent change from baseline to week 52 in high-sensitivity C-reactive protein (hs-CRP) • Change from baseline to week 52 in BMI • Percent change from baseline to week 52 in low density lipoprotein cholesterol (LDL-C) • Percent change from baseline to week 52 in total cholesterol • Percent change from baseline to week 52 in high density lipoprotein cholesterol (HDL-C) • Percent change from baseline to week 52 in non-HDL-C • Percent change from baseline to week 52 in very low-density lipoprotein cholesterol (VLDL-C) • Percent change from baseline to week 52 in triglycerides • Percent change from baseline to week 52 in free fatty acids (FFA);Timepoint(s) of evaluation of this end point: From baseline to week 52
