NCT05505448

Brief Summary

The primary objective of the study is to evaluate the safety and tolerability of REGN14284 in healthy participants, as measured by all treatment-emergent adverse events (TEAEs) and treatment-emergent serious adverse events (SAEs). The secondary objectives of the study are:

  • To assess the concentration-time profile of REGN14284 in serum
  • To assess the immunogenicity of REGN14284

You may qualify if:

  • Has SARS-CoV-2-negative test result from a sample collected ≤72 hours prior to randomization as described in the protocol.
  • Has received complete primary series of standard-of-care COVID-19 vaccination per local guidance, completed at least 2 weeks prior to screening
  • Has a body mass index (BMI) between 18 and 31 kg/m2 (inclusive) at the screening visit
  • Is judged by the investigator to be in good health based on medical history, physical examination, vital sign measurements, laboratory safety testing and ECGs performed at screening and/or prior to administration of study drug

You may not qualify if:

  • History of clinically significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, infectious, autoimmune, oncologic, psychiatric or neurological disease, as assessed by the investigator as described in the protocol
  • Presents any concern to the investigator that might confound the results of the study or poses an additional risk to the participant by their participation in the study
  • Was hospitalized (ie, \>24 hours) for any reason within 30 days of the screening visit
  • Has a history of alcohol or drug abuse as determined by the investigator
  • Has a history of significant multiple and/or severe allergies, or has had an anaphylactic reaction to drugs or food as described in the protocol
  • Use of any medications or nutritional supplements within approximately 5 half-lives or 2 weeks, whichever is longer, prior to first administration of the study drug through the end of the study, except for the permitted medications listed as described in the protocol
  • Participated in any clinical research study evaluating another investigational drug including biologics or specific immunotherapy, within at least 5 half-lives or 90 days (whichever is longer) of an investigational biologic drug, or at least 4 weeks for small molecules or other investigational drugs, prior to the screening visit
