Confirmation of SARS-CoV-2 infection will be performed through rapid antigen detection using the LumiraDx point of care diagnostic platform. Approximately 4000 eligible patients will be enrolled and will be randomised in a 1:1 manner to start treatment with either molnupiravir or a placebo on the same day. Patients will record their symptoms (through a self-administered questionnaire) and self-observed vital signs daily for 10 days from the time of enrolment and will be contacted by study team personnel on Days 3, 6 and 10 to monitor their well-being. Adverse event and concomitant medication data will be collected. A final end-of-study follow-up visit will be conducted on Day 29.\n\nAn independent Data and Safety Monitoring Board (DSMB) will be convened for this study with expertise in COVID-19 or respiratory viruses, and emerging epidemics. The purpose of the DSMB is to monitor the study for safety and operational futility.\n\nIn addition to the usual, regular, required reporting to SAHPRA, the investigator anticipates that additional reporting will be required by the Clinical Trials Committee, noting the severity of the 3rd and 4th waves, the level of ''breakthrough'' infections in the context of high background comorbidities, and the urgent interest in this class of drugs."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '50 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.

Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs, or which may jeopardize the safety of the patient or the objectives of the study. The Investigator should make this determination in consideration of the volunteer's medical history.\n7. The volunteer is assessed to be clinically unstable in the Investigator's opinion.\n8. Participation in another investigational study involving an investigational product within 30 days, or 5 half-lives, whichever is longer, prior to screening.\n9. Personnel (e.g., investigator, sub-investigator, research assistant, pharmacist, study coordinator or anyone mentioned in the delegation log) directly involved in the conduct of the study.\n10. Any physical, mental, or social condition, drug/alcohol use, history of illness or laboratory abnormality that, in the Investigator's judgment, might jeopardise the safety of the patient in the context of this study, or might interfere with study procedures or the ability of the subject to adhere to and complete the study.
