Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is researching an experimental drug called REGN13335. This is the first time that REGN13335 will be given to people. This study will enroll healthy adults.

The aim of the study is to see how safe and tolerable REGN13335 is in healthy volunteers.

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 present in the blood of study participants 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)
