Outcome Measures

Primary Outcomes (4)

  • Percentage of Participants With RT-PCR Confirmed Symptomatic COVID-19 (PEP)

    RT-PCR-confirmed symptomatic COVID-19 is determined by a positive central or local (in the absence of central test) RT-PCR test from a nasopharyngeal or saliva sample accompanied by protocol-defined COVID-19 symptoms occurring within 14 days from the sample collection date. Any COVID-19-related hospitalization with a positive local SARS-CoV-2 test (within 14 days) or all-cause death are counted toward the endpoint.

    Day 1 through Day 28 or emergence of Omicron (15-Dec-2021), whichever is earlier

  • Percentage of Participants With RT-PCR Confirmed Symptomatic COVID-19 (PrEP)

    RT-PCR-confirmed symptomatic COVID-19 is determined by a positive central or local (in the absence of central test) RT-PCR test from a nasopharyngeal or saliva sample accompanied by protocol-defined COVID-19 symptoms occurring within 14 days from the sample collection date. Any COVID-19-related hospitalization with a positive local SARS-CoV-2 test (within 14 days) or all-cause death are counted toward the endpoint.

    Day 1 through 3 Months or emergence of Omicron (15-Dec-2021), whichever is earlier

  • Solicited Injection Site Reactions (PEP, PrEP)

    Percentage of participants with at least one solicited injection site reaction

    Day 1 through Day 4

  • Participants With at Least 1 Treatment Emergent Adverse Events (PEP, PrEP)

    Any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment; includes solicited injection site reactions

    Day 1 through 14 Months or 25Jul2022, whichever is earlier

Secondary Outcomes (22)

  • Percentage of Participants With RT-PCR Confirmed Symptomatic COVID-19 (PEP)

    Day 1 through Day 28 or emergence of Omicron (15-Dec-2021), whichever is earlier

  • Percentage of Participants With SARS-CoV-2 Infection (Asymptomatic or Symptomatic) as Determined by Positive RT-PCR or Serology (PEP)

    Day 1 through Day 28 or emergence of Omicron (15-Dec-2021), whichever is earlier

  • Percentage of Participants With Asymptomatic SARS-CoV-2 Infection as Determined by RT-PCR (PEP)

    Day 1 through Day 28 or emergence of Omicron (15-Dec-2021), whichever is earlier

  • Percentage of Participants With Asymptomatic SARS-CoV-2 Infection as Determined by Serology (PEP)

    Day 1 through Day 28 or emergence of Omicron (15-Dec-2021), whichever is earlier

  • Percentage of Participants With Asymptomatic SARS-CoV-2 Infection as Determined by Serology (PrEP)

    Day 1 through 6 Months or emergence of Omicron (15-Dec-2021), whichever is earlier

Eligibility Criteria

Age12 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Tests negative for current or previous SARS-CoV-2 infection by RT-PCR and serology (Pre-exposure population only)
  • Is at high risk of SARS-CoV-2 infection as assessed by the Investigator:
  • Post-exposure population: exposure to an individual with a diagnosis of SARS-CoV-2 infection (index case). Note: Participants with recent exposure to a laboratory-confirmed index case must be asymptomatic and randomized within 5 days (120 hours) of collection of the index case's positive SARS-CoV-2 diagnostic test.
  • Pre-exposure population: Occupational, housing, recreational and/or social conditions that are likely to increase risk of exposure to SARS-CoV-2.
  • Agrees to defer receipt of COVID-19 vaccination for minimum of 180 days (6 months) after dosing

You may not qualify if:

  • Has received (1) a SARS-CoV-2 vaccine, (2) mAb or (3) convalescent plasma from a person who has recovered from COVID-19 or prior participation in SARS-CoV2 vaccine, convalescent plasma, or mAb clinical trial any time prior to participation in the study.
  • Receipt of any investigational product within 30 days or 5 half lives before the day of enrollment.
  • Is acutely ill or febrile 72 hours before or at Screening or has other COVID-19 symptoms including cough, fatigue, muscle or body aches, headache, or loss of taste or smell. Fever is defined as a body temperature ≥38.0°C (≥100.4°F).
  • Has received or plans to receive a non-COVID-19 vaccine within 28 days before or after dosing (except for seasonal influenza vaccine, which is not permitted within 14 days before or after dosing).
