Study Assessing the Safety, Tolerability, Pharmacokinetics, and Immunogenicity of Repeated Subcutaneous Doses of Anti-Spike (S) SARS-CoV-2 Monoclonal Antibodies (REGN10933+REGN10987) in Adult Volunteers as Related to COVID-19

Phase 1
Completed
Conditions
Healthy
Chronic Stable Illness
Interventions
Registration Number
NCT04519437
Lead Sponsor
Regeneron Pharmaceuticals
Brief Summary

The primary objectives are:

* To assess the occurrence of adverse events of special interest (AESIs) in participants treated with repeated subcutaneous (SC) doses of REGN10933+REGN10987 compared to placebo

* To assess the concentrations of REGN10933 and REGN10987 in serum over time after single and repeated SC administration

The secondary objectives are:

* To assess the safety and tolerability of repeated SC doses of REGN10933+REGN10987 compared to placebo

* To assess attainment of target concentrations of REGN10933 and REGN10987 in serum after single and repeated SC administration

* To assess the immunogenicity of REGN10933 and REGN10987
