The period of exclusion begins 1 month after the final dose or 5 half-lives after the final dose or 1 month after the last visit, whichever is the longest. - History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity. - Current smokers or those who have smoked or used nicotine products (including e cigarettes) within the 6 months prior to screening. - Use of any prescribed or non prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies (which include but are not limited to: kava, ephedra [ma hung], ginko biloba, dehydroepiandrosterone, yohimbe, saw palmetto and ginseng), megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks prior to the first administration of IMP or longer (> 5 half-lives) if the medication has a long half-life. - Subject has clinical signs and symptoms consistent with COVID-19, or confirmed infection by appropriate laboratory test within the last 4 weeks prior to screening or on admission unless confirmed by a negative SARS CoV-2 PCR test. - History of severe COVID-19 (hospitalization, extracorporeal membrane oxygenation, mechanically ventilated). - Excessive intake of caffeine-containing drinks or food. - Planned in-patient surgery, dental procedure, or hospitalization during the study. - Receipt of live attenuated vaccine within 30 days prior to the first dose of study drug. - Received a seasonal flu vaccine (including H1N1, H1N5) 28 days prior to first dose of study drug. |
