Clinical Trial 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

3. Has a body mass index (BMI) between 18 and 31 kg/m2 (inclusive) at the screening visit

4. 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

Key Exclusion Criteria:

1. 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

5. 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

6. 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

7. 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 NOTE: Other protocol defined inclusion / exclusion criteria apply
