1. The subject is male or female aged ≥ 45 years. 2. The subject is able to understand and provide signed informed consent. 3. The subject is tested to confirm infection with SARS-CoV-2 by lateral flow antigen test or RT-PCR on a sample taken within 3 days before randomization. 4. The subject is either without symptoms or has one or more of the following symptoms: stuffy or runny nose, sore throat, loss of taste, loss of smell, or headache (to be entered in the FDA COVID-19 questionnaire). Conjunctivitis is also acceptable. None of the symptoms should have been present > 5 days. 5. Men whose sexual partners are women of childbearing potential (WOCBP) must agree to comply with one of the following contraception requirements from the time of first dose of screening until at least 30 days after the last dose of study medication: a. Vasectomy with documentation of azoospermia. b. Sexual abstinence (defined as refraining from heterosexual intercourse from the time of screening until at least 30 days after the last dose of study medication) c. Male condom plus partner use of one of the contraceptive options below: contraceptive subdermal implant, intrauterine device of intrauterine system, oral contraceptive, either combine or progestogen alone, injectable progestogen, contraceptive vaginal ring, percutaneous contraceptive patches. The above is an all-inclusive list of those methods that meet the following definition of highly effective: having a failure rate of less than 1% per year when used consistently and correctly and, when applicable, in accordance with the product label. For non-product methods (e.g., male sterility), the investigatory will determine what is consistent and correct use. The investigator is responsible for ensuring that patients understand how to properly use these methods of contraception. 6. WOCBP must agree to comply with one of the following contraception requirements from the time of screening until at least 30 days after the last dose of study medication: a. Sexual abstinence (defined as refraining from heterosexual intercourse from the time of screening until at least 30 days after the last dose of study medication). b. Use of one of the contraceptive options below plus use of a condom by male partner: contraceptive subdermal implant, intrauterine device or intrauterine system, oral contraceptive, either combined or progestogen alone, injectable progestogen, contraceptive vaginal ring, percutaneous contraceptive patches. c. Vasectomy of male partner with documentation of azoospermia. The above is an all-inclusive list of those methods that meet the following definition of highly effective: having a failure rate of less than 1% per year when used consistently and correctly and, when applicable, in accordance with the product label. The investigator is responsible for ensuring that patients understand how to properly use these methods of contraception. Women of non-reproductive potential are defined as: a) Premenopausal females with one of the following: documented tubal ligation, documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, hysterectomy, documented bilateral oophorectomy. b) Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample will be required with simultaneous follicle stimulating hormone and estradiol levels tested locally and consistent with menopause [refer to local laboratory reference ranges for confirmatory levels]). Women on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods listed above if they wish to continue their HRT during the study.
