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 REGN7508 (called "study drug"). The aim of this study is to see how safe and tolerable the study drug is in healthy participants.

This 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 the 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)

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Body mass index between 18.0 and 32.5 kg/m2 (inclusive) at the screening visit
2. Judged by the investigator to be in good health based on medical history, physical examination, vital sign measurements, and echocardiograms (ECGs) performed at screening and/or prior to administration of initial dose of study drug
3. Participant is in good health based on laboratory safety testing obtained at the screening visit and/or prior to administration of initial dose of study drug
4. Normal activated partial thromboplastin time (aPTT), normal prothrombin time (PT), and normal platelet counts at screening period and at the day -1 visit as defined by the local laboratory
5. Hemoglobin value ≥11.0 g/dL for females and ≥12.9 g/dL for males at the screening and day 1 visits

Exclusion Criteria

2. Whole blood donation within the previous 56 days or plasma donation within the previous 7 days prior to the screening visit
3. History of clinically significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, psychiatric, neurological, or dermatologic disease, as assessed by the investigator, that may confound the results of the study or poses an additional risk to the participant by study participation, as defined in the protocol
4. Estimated glomerular filtration rate (eGFR) of \<60 mL/min/1.73m2 at screening
5. Current smoker or former smoker, including e-cigarettes, who stopped smoking within 12 months prior to the screening visit
