Study Overview
=================
Brief Summary
-----------------
This is a phase 1, randomized, double-blind, placebo-controlled, multiple ascending dose study to assess the safety, tolerability, pharmacokinetic (PK), immunogenicity, and pharmacodynamic (PD) effects of REGN1500 in patients with a metabolic disorder.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety | Safety of REGN1500 will be assessed by physical examination, vital signs, electrocardiogram (ECG), and clinical laboratory evaluations from visit 1 to day 183 [EOS (end of study)] | visit 1 to day 183 (EOS) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Serum concentration | Serum concentration, amount of REGN1500 in the circulation, over time (visit 1 to day 183) | visit 1 to day 183 |
