NCT04470427

Brief Summary

The mRNA-1273 vaccine is being developed to prevent COVID-19, the disease resulting from Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) infection. The study is designed to primarily evaluate the efficacy, safety, and immunogenicity of mRNA-1273 to prevent COVID-19 for up to 2 years after the second dose of mRNA-1273.

Outcome Measures

Primary Outcomes (5)

  • Part A: Number of Participants With a First Occurrence of COVID-19 Starting 14 Days After Second Dose

    COVID-19 cases were defined as participants meeting clinical criteria based both on symptoms for COVID-19 and on RT-PCR detection of SARS-CoV-2 from samples collected within 72 hours of the study participant reporting symptoms that met the definition of COVID-19. An adjudication committee was assembled for the purpose of reviewing potential cases to determine if the criteria for COVID-19 were met.

    From Day 43 (14 days after second dose) up to approximately 7 months after the second dose

  • Part A: Number of Participants With Solicited Local and Systemic Adverse Reactions (ARs) After First Dose

    Solicited ARs (local and systemic) were collected in electronic diary (eDiary) within 7 days of dosing. Local ARs included: pain at injection site, erythema (redness) at injection site, swelling/induration (hardness) at injection site, and localized axillary swelling or tenderness ipsilateral to the injection arm. Systemic ARs included: headache, fatigue, myalgia (muscle aches all over the body), arthralgia (aching in several joints), nausea/vomiting, rash, body temperature (potentially fever), and chills. Severity grading for solicited ARs is based on modified Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventative Vaccine Clinical Trials. Severity was graded 0-4; a lower score indicated lower severity and a higher score indicated greater severity. The Investigator determined if solicited AR was also to be recorded as an AE. Summary of serious AEs (SAEs) and nonserious AEs ("Other"), regardless of causality, is in Reported "Adverse Events" section.

    up to Day 7 (7 days after first dose)

  • Part A: Number of Participants With Solicited Local and Systemic Adverse Reactions (ARs) After Second Dose

    Solicited ARs (local and systemic) were collected in eDiary within 7 days of dosing. Local ARs included: pain at injection site, erythema (redness) at injection site, swelling/induration (hardness) at injection site, and localized axillary swelling or tenderness ipsilateral to the injection arm. Systemic ARs included: headache, fatigue, myalgia (muscle aches all over the body), arthralgia (aching in several joints), nausea/vomiting, rash, body temperature (potentially fever), and chills. Severity grading for solicited ARs is based on modified Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventative Vaccine Clinical Trials. Severity was graded 0-4; lower score indicated lower severity and a higher score indicated greater severity. The Investigator determined if solicited AR was also to be recorded as an AE. Summary of serious AEs (SAEs) and nonserious AEs ("Other"), regardless of causality, is in Reported "Adverse Events" section

    Day 29 to Day 35 (from second dose to 7 days after second dose)

  • Parts A and B: Number of Participants With Medically Attended AEs (MAAEs) and AEs Leading to Discontinuation

    An MAAE is an AE that leads to an unscheduled visit to a healthcare practitioner (HCP). A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section.

    Day 1 (after dosing) through end of study (up to Day 759)

  • Parts A and B: Number of Participants With Serious AEs (SAEs)

    An SAE was defined as any AE that resulted in death, is life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in disability/permanent damage, was a congenital anomaly/birth defect, or was an important medical event. A summary of SAEs and all nonserious AEs ("Other"), regardless of causality, is located in the Reported "Adverse Events" section.

    Day 1 (after dosing) through end of study (up to Day 759)

Secondary Outcomes (15)

  • Part A: Number of Participants With Unsolicited AEs up to 28 Days After Any Injection Dose

    Up to 28 days after any dose

  • Parts A and B: Number of Participants With a First Occurrence of Severe COVID-19 Starting 14 Days After Second Dose

    From Day 43 (14 days after second dose) up to approximately 8 months for Part A and from PDV/unblinding (at 4 months) to up to 8 months for Part B

  • Part A: Number of Participants With a First Occurrence of Either COVID-19 or SARS-CoV-2 Infection Regardless of Symptomatology or Severity Starting 14 Days After Second Dose

    From Day 43 (14 days after second dose) up to approximately 7 months after the second dose

  • Part A: Number of Participants With a Secondary Case Definition of COVID-19 Starting 14 Days After Second Dose

    From Day 43 (14 days after second dose) up to approximately 7 months after the second dose

  • Parts A and B: Number of Participants Who Died Due to a Cause Directly Attributed to a Complication of COVID-19 Starting 14 Days After Second Dose

    From Day 43 (14 days after second dose) up to approximately 8 months for Part A and from PDV/unblinding (at 4 months) to up to 8 months for Part B

  • +10 more secondary outcomes

Study Arms (2)

mRNA-1273

EXPERIMENTAL

Part A (Blinded): Participants will receive 1 intramuscular (IM) injection of 100 microgram (μg) mRNA-1273 on Day 1 and on Day 29. Part B (Open-label): Participants who receive mRNA-1273-matching placebo during Part A and choose to be unblinded by participating in Part B, will receive 1 IM injection of 100 μg mRNA-1273 on Day 1 and Day 29. Participants who are only able to receive 1 dose of mRNA-1273 due to administrative reasons, will receive 1 IM injection of 100 μg mRNA-1273 on Day 1, if the participant chooses. Part C: Eligible participants in Part B who choose to receive booster dose of mRNA-1273, will receive 1 IM injection of 50 μg mRNA-1273 on Day 1.
