Summary
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)
