Brief summary

The study is researching an experimental drug called REGN7544.The study is focused on healthy adults. The aim of the study is to see how safe and tolerable the study drug is in healthy adults. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in your blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

Interventions
