Exclusion criteria: ? Subject currently receiving treatment in another investigational device or drug study, or ended treatment on another investigational device or drug study(s) within 8 weeks prior to screening. ? Other investigational procedures while participating in this study are excluded. ? Anticipated or scheduled parathyroidectomy during the study period. ? Subject has received a parathyroidectomy within 3 months prior to dosing. ? Anticipated or scheduled kidney transplant during the study period. ? Subject has known sensitivity to any of the products or components to be administered during dosing. ? Subject has previously entered this study. ? Subject has participated in a prior clinical trial of AMG 416 (also referred to as KAI-4169). ? Subject has received cinacalcet within the 4 weeks prior to screening labs ? Subject has an unstable medical condition based on medical history, physical examination, and routine laboratory tests, or is otherwise unstable in the judgment of the Investigator. ? Subject has a history of any illness that, in the opinion of the Investigator, might confound the results of the study or pose additional risk to the subject. ? Subject history of malignancy within the last 5 years (except non-melanoma skin cancers, or cervical carcinoma in situ). ? Subject has a serious concurrent medical condition (eg, malignancy) likely to result in death during the next 12 months. ? Subject is pregnant or nursing. ? Subject has a history of symptomatic ventricular dysrhythmias or Torsades de Pointes. ? Subject?s screening 12-lead electrocardiogram (ECG) suggests unstable arrhythmia or other cardiac abnormality that could place the subject at increased risk, based upon the Investigator?s opinion. ? Subject has a history of poorly controlled hypertension (eg, persistent or recurrent postdialysis systolic blood pressure (SBP) > 180 mmHg or DBP > 110 mmHg during the 3 months prior to screening). ? Subject has a history of angina pectoris with symptoms that occur at rest or minimal activity or a history of congestive heart failure (New York Heart Association Classification III or IV). ? Subject has a history of myocardial infarction, coronary angioplasty, or coronary arterial bypass grafting within the past 6 months prior to screening. ? Subject is receiving treatment for a seizure disorder or has a history of a seizure within the last 12 months prior to screening. ? Subject has had surgery (except minor surgery) within the last 8 weeks prior to screening. ? Subject has clinically significant abnormalities on prestudy clinical examination or central laboratory tests during the 4 weeks prior to randomization according to the Investigator including but not limited to the following: ? Serum albumin ? 3.0 g/dL ? Serum magnesium < 1.5 mg/dL ? Hemoglobin < 8.5 g/dL ? Platelet count < 100,000 x106/L ?

Subject likely to not be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures to the best of the subject and Investigator?s knowledge. ? History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) that, in the opinion of the I
