A Trial to Learn if Different Doses of REGN7544 Are Safe in Healthy Adult Participants

Phase 1
Completed
Conditions
Healthy Volunteers
Interventions
Drug: Matching Placebo
Registration Number
NCT05970718
Lead Sponsor
Regeneron Pharmaceuticals
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)

History of clinically significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, psychiatric or neurological 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
  2. History, in the past 2 years of a diagnosis of hypertension, symptomatic hypotension (BP <90/50 mmHg with associated symptoms), symptomatic orthostatic hypotension, postural orthostatic tachycardia syndrome, syncope, or clinically significant cardiac arrhythmia
  3. Presents any concern to the study investigator that might confound the results of the study or poses an additional risk to the participant by their participation in the study
  4. Was hospitalized (ie, >24 hours) for any reason within 30 days of screening
  5. Is a current smoker or former smoker, including e-cigarettes, who stopped smoking within 3 months prior to screening
