  3. Participants must not have had COVID-19 symptoms within 10 days of dosing
  4. Negative result from point of care SARS-CoV-2 serology test at screening
  5. Contraception used by women of childbearing potential, condom by men
  6. Able to understand and comply with study requirements/procedures based on the assessment of the investigator

Exclusion Criteria:

  2. History of infection with severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS).
  3. Known history of allergy or reaction to any component of the study drug formulation.
  4. Previous hypersensitivity, infusion-related reaction, or severe adverse reaction following administration of a mAb.
  5. Any prior receipt of investigational or licensed vaccine or other mAb/biologic indicated for the prevention of SARS-CoV-2 or COVID-19 or expected receipt during the period of study follow up.
  6. Clinically significant bleeding disorder or prior history of significant bleeding or bruising following IM injections or venipuncture.
  7. Any other significant disease, disorder, or finding that, in the judgement of the investigator, may significantly increase the risk to the participant because of participation in the study, affect the ability of the participant to participate in the study, or impair interpretation of the study data.
  8. Receipt of any IMP in the preceding 90 days or expected receipt of IMP during the period of study follow-up, or concurrent participation in another interventional study.
  9. Currently pregnant or breast feeding.
  10. Blood drawn in excess of a total of 450 mL (1 unit) for any reason within 30 days prior to randomization.
  11. Employees of the Sponsor involved in planning, executing, supervising, or reviewing the AZD7442 program, clinical study site staff, or any other individuals involved with the conduct of the study, or immediate family members of such individuals.
  12. In nations, states, or other jurisdictions that for legal or ethical reasons bar the enrollment of participants who lack capacity to provide their own informed consent, such subjects are excluded.

5. Study Description

Brief Summary
This study will assess the efficacy of AZD7442 for the post-exposure prophylaxis of COVID-19 in Adults.
Detailed Description
SARS-CoV-2 is the causative agent of the ongoing COVID-19 pandemic that, as of 29 September 2020, has resulted in a high death toll to date. Unlike the majority of coronaviruses that cause mild disease in humans and animals, SARS-CoV-2 can replicate in the lower respiratory tract to cause acute respiratory distress syndrome and fatal pneumonia. Effective interventions to prevent or treat COVID-19 remain limited in number and clinical experience is limited. Clinical management is limited to supportive care, consequently overwhelming resources of healthcare systems around the world. As a response to the ongoing pandemic, AstraZeneca is developing mAbs to the SARS-CoV-2 S protein. The SARS-CoV-2 spike protein contains the virus's RBD, which enables the virus to bind to receptors on human cells. By targeting this region of the virus's spike protein, antibodies can block the virus's attachment to human cells, and, therefore, is expected to block infection. Amino acid substitutions have been introduced into the antibodies to both extend their half-lives, which should prolong their potential prophylactic benefit, and decrease Fc effector function in order to decrease the potential risk of antibody-dependent enhancement of disease. AZD7442, a combination of 2 of these mAbs (AZD8895 and AZD1061), is being evaluated for administration to prevent and/or treat COVID-19. There is currently one ongoing Phase I study with AZD7442.
