Brief summary

The primary objectives of the study are: * To evaluate the extent of effect, if any, of REGN10933+REGN10987 administration on vaccine-induced neutralizing antibody responses to SARS-CoV-2 by Moderna mRNA-1273 * To evaluate the time interval required between REGN10933+REGN10987 administration and Moderna mRNA-1273 vaccination, to ensure no meaningful impact on vaccine-induced neutralizing antibody responses to SARS-CoV-2 The secondary objectives of the study are: * To quantify the alteration of antigen specificity of vaccine-induced SARS-CoV-2 antibody responses when administered with different dose regimens of REGN10933+REGN10987 * To evaluate the safety and tolerability of REGN10933+REGN10987 and Moderna mRNA-1273 vaccine when administered in close succession * To assess the concentrations of REGN10933 and REGN10987 in serum over time in participants who receive REGN10933+REGN10987 and Moderna mRNA-1273 vaccine * To evaluate the immunogenicity of REGN10933 and REGN10987 over time

Absolute Values in Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S1-RBD IgA)

Anti-S1-RBD protein

Time frame: Up to 365 Days from 1st dose of Vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Absolute Values in Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S1-RBD IgG)

Anti-S1-RBD

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Absolute Values in Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S-IgG)

Anti-S protein

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Absolute Values in Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S-IgM)

Anti-S protein (Spike protein)

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Fold Change of Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S1-RBD IgG)

Anti-S1-RBD protein Fold Change based on medians = (median value in vaccine only arm / median value in the active arm)

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Fold Change of Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S-IgM)

Anti-S protein (Spike protein) Fold Change based on medians = (median value in vaccine only arm / median value in the active arm)

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Median Fold Change of Concentrations of Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S1-RBD IgA)

Anti-S1-RBD protein. Fold Change based on medians = (median value in vaccine only arm / median value in the active arm)

Time frame: Up to 365 Days from 1st dose of Vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine,

Relative Difference Expressed as a Percent in Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S1-RBD IgA)

Anti-S1-RBD protein. Relative difference is calculated as: \[(LS Geometric Mean Active Arm - LS Geometric Mean Vaccine Alone Arm) / LS Geometric Mean Vaccine Alone Arm\] x 100%

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Relative Difference Expressed as a Percent in Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S1-RBD IgG)

Anti-S1-RBD protein Relative difference is calculated as: \[(LS Geometric Mean Active Arm - LS Geometric Mean Vaccine Alone Arm) / LS Geometric Mean Vaccine Alone Arm\] x 100%

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Secondary

Relative Difference Expressed as a Percent in Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S-IgA)

Anti-S protein Relative difference is calculated as: \[(LS Geometric Mean Active Arm - LS Geometric Mean Vaccine Alone Arm) / LS Geometric Mean Vaccine Alone Arm\] x 100%

Time frame: Up to 365 Days from 1st dose of Vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.

Secondary

Relative Difference Expressed as a Percent in Vaccine-induced Antibodies to SARS-CoV-2 Antigens Over Time (S-IgG)

Anti-S protein (Spike) Relative difference is calculated as: \[(LS Geometric Mean Active Arm - LS Geometric Mean Vaccine Alone Arm) / LS Geometric Mean Vaccine Alone Arm\] x 100%

Time frame: Up to 365 Days from 1st dose of vaccination

Population: Per protocol set (PPS) includes all randomized participants who have received both doses of vaccine and who do not meet the exclusion criteria. The PPS is the primary analysis set for assessing vaccine response related endpoints. As was pre-specified in the study protocol, only participants in the Vaccine Only and REGN10933+REGN10987 + Vaccine 1200 mg Day 7 Arm/Group were assessed for measure 6 days after the first vaccine.
