Conditions

Long-term persistence of SARS-CoV-2

Brief summary

Percent of participants from group B with absence of SARSCoV- 2 (CT value > 30) from a combined nose/throat swab at day 15 and day 22. For reaching the endpoint, test results from both days need to be negative.

Detailed description

a) Percentage of participants with treatment-emergent AEs (TEAEs). b) Percentage of participants with SAEs in groups A and B. c) Percentage of participants with early treatment discontinuation in groups A and B., % participants from group A with absence of SARS-CoV-2 from a combined nose/throat swab at day 15 and day 22., % of severely immunocompromised participants from group A and B with absence of SARS-CoV-2 from a combined nose/throat swab at day 15 and day 22, Assessment of SARS-CoV-2 RNA in combined nose/throat swabs at baseline. In participants with measurable baseline levels, changes from baseline to days 5, 15, 22, and 50 will be assessed., Mean time to first negative SARS-CoV-2 PCR (CT value > 30) in each group., Acute COVID-19 signs and symptoms diary and Global Impression Questions: a) Change in % of patients in each response category from baseline to days 5, 10, 15, 22, and 50. b) Worsening status or new onset of symptoms in 1 or more categories from baseline to days 5, 10, 15, 22, and 50, a) Proportion of participants admitted to the intensive care unit by Day 50. b) All-cause mortality at day 50.
