PRIMARY outcome

Timeframe: Up to 7 days post-dose1

Population: Analysis was performed on safety set that included all participants who received at least one dose of investigational medicinal product (IMP). Here, overall number of participants analyzed signifies participants with available data for the analysis.

A solicited reaction was defined as an adverse reaction observed and reported under the conditions (symptom and onset) and pre-listed (that is, solicited) in the e-diary. Solicited local reactions included: pain, erythema/redness, and induration/swelling.

PRIMARY outcome

Timeframe: Up to 7 days post-dose 2

Population: Analysis was performed on dose 2 safety set, that is, all participants who received two doses of IMP. Here, overall number of participants analyzed signifies participants with available data for the analysis.

A solicited reaction was defined as an adverse reaction observed and reported under the conditions (symptom and onset) and pre-listed (that is, solicited) in the e-diary. Solicited local reactions included: pain, erythema/redness, and induration/swelling. Data for this outcome measure was not collected and analyzed for Cohort 1, and Comparator Cohorts A and B, as these Cohorts did not receive Dose 2 of the study drugs.

Timeframe: Up to 7 days post-dose 1

Population: Analysis was performed on safety set that included all participants who received at least one dose of IMP. Here, overall number of participants analyzed signifies participants with available data for the analysis.

A solicited reaction was defined as an adverse reaction observed and reported under the conditions (symptom and onset) pre-listed (i.e., solicited) in the e-diary. Solicited systemic reactions included: vomiting, diarrhea, headache, fatigue, myalgia, arthralgia, chills, and fever.

PRIMARY outcome

Timeframe: Up to 6 to 7 months post-dose 2 for Cohorts 2 to 4; and up to 3 months post-dose 2 for Cohort 5

Population: Analysis was performed on dose 2 safety set. Data for this outcome measure was not collected and analyzed for Cohort 1, and Comparator Cohorts A and B as these Cohorts did not receive Dose 2 of the study drugs.

An SAE was defined as any untoward medical occurrence that, at any dose, resulted in death and was life-threatening. It also included any event requiring hospitalization or prolongation of existing hospitalization, resulted in persistent disability/incapacity, caused a congenital anomaly or birth defect, or any other event determined as SAE as per medical or scientific judgment.

PRIMARY outcome

Timeframe: At Day 7 post-dose 2

Population: Analysis was performed on dose 2 safety set. Data for this outcome measure was not collected and analyzed for Cohort 1, and Comparator Cohorts A and B as these Cohorts did not receive Dose 2 of the study drugs.

Participants with laboratory abnormalities (clinical chemistry) for alanine aminotransferase, albumin, alkaline phosphatase, amylase, aspartate aminotransferase, C-reactive protein, creatinine, direct bilirubin, gamma glutamyl transferase, glucose, high sensitivity C reactive protein, indirect bilirubin, lipase, total bilirubin, troponin I type 3 and urea nitrogen were analyzed and only clinically significant abnormal data was reported in the outcome measure.

Population: Analysis was performed on safety set. Here, number analyzed signifies participants with available data for each specified category and "0" in the number analyzed field signifies that no participants were available for analysis.

The intensity of AEs and laboratory parameters was graded by the investigator. Grades were defined as: Grade 1 - Mild; does not interfere with the trial participant's usual function; Grade 2 - Moderate; interferes to some extent with the trial participant's usual function; Grade 3 - Severe; interferes significantly with the trial participant's usual function and Grade 4 - Potentially life-threatening; life-threatening consequences, urgent intervention required. Participants with shift change from Baseline Grade 0 to Worst Grade \>=3 were reported in the outcome measure.

PRIMARY outcome

Timeframe: At Day 7 post-dose 2

Population: Analysis was performed on dose 2 safety set. Data for this outcome measure was not collected and analyzed for Cohort 1, and Comparator Cohorts A and B as these Cohorts did not receive Dose 2 of the study drugs.

The intensity of AEs and laboratory parameters was graded by the investigator. Grades were defined as: Grade 1 - Mild; does not interfere with the trial participant's usual function; Grade 2 - Moderate; interferes to some extent with the trial participant's usual function; Grade 3 - Severe; interferes significantly with the trial participant's usual function and Grade 4 - Potentially life-threatening; life-threatening consequences, urgent intervention required. Participants with shift change from Baseline Grade 0 to Worst Grade \>=3 were reported in the outcome measure.

PRIMARY outcome

Timeframe: At Day 3 post-dose 1; at Day 7 post-dose 1

Population: Analysis was performed on safety set. Here, number analyzed signifies participants with available data for each specified category and "0" in the number analyzed field signifies that no participants were available for analysis.

The intensity of AEs and laboratory parameters was graded by the investigator. Grades were defined as: Grade 1 - Mild; does not interfere with the trial participant's usual function; Grade 2 - Moderate; interferes to some extent with the trial participant's usual function; Grade 3 - Severe; interferes significantly with the trial participant's usual function and Grade 4 - Potentially life-threatening; life-threatening consequences, urgent intervention required.

SECONDARY outcome

Timeframe: At Pre-dose and Day 28 post dose-1

Population: Analysis was performed on Immunogenicity per protocol set that is all participants who received the planned dose of the IMP on Day 1 and who have at least one valid immunogenicity assessment within an appropriate window and have no major protocol deviations that can confound immunogenicity data. Here, overall number of participants analyzed signifies participants with available data for the analysis and number analyzed signifies participants with available data for each specified category.

GMTs for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) neutralizing antibody ancestral strain were measured by valid assay method. Data for this outcome measure was not planned to be collected and analyzed for Cohort 5.
