Brief Summary:
Two cohorts are being studied based on leptin levels. Cohort A is composed of patients with baseline leptin \<8.0 ng/mL and Cohort B is composed of patients with baseline leptin 8.0 to ≤20.0 ng/mL
The primary objectives will be evaluated for patients in Cohort A only:
* To evaluate the effect of REGN4461 on fasting triglycerides (TG) in patients with elevated baseline fasting TG
* To evaluate the effect of REGN4461 on hyperglycemia in patients with elevated baseline Hemoglobin A1c (HbA1c)
The following secondary objectives of the study will be evaluated for Cohort B and for the combined set of Cohorts A plus B:
* To evaluate the effect of REGN4461 on fasting TG levels in patients with hypertriglyceridemia
* To evaluate the effect of REGN4461 on glycemic control in patients with hyperglycemia
The following secondary objectives of the study will be evaluated for Cohorts A and B separately, and for the combined set of Cohorts A plus B:
* To evaluate the effect of REGN4461 on liver fat in patients with hepatic steatosis
* To evaluate the effect of REGN4461 on hunger
* To evaluate safety and tolerability of REGN4461
* To characterize the concentration profile of REGN4461 over time
* To assess immunogenicity to REGN4461
