Measure
ANA001
Subjects in the ANA001 treatment arm will receive 1,000 mg (4 capsules; 250 mg each) by mouth twice per day for 7 consecutive days with a meal. If the participant requires mechanical ventilation over the course of the study, ANA001 may be administered via nasogastric (NG), percutaneous endoscopic gastrostomy (PEG) or orogastric (OG) tube and, if possible, should be administered with a scheduled nasogastric (NG) or orogastric (OG) feeding. Niclosamide: Niclosamide is an antihelmintic with in-vitro antiviral activity
Matching Placebo
Subjects in the comparator arm will receive matching placebo (hydroxypropylmethylcellulose (HPMC)) (4 capsules, by mouth twice a day) for the 7-day treatment duration. Placebo: Matching hydroxypropylmethylcellulose HPMC capsules with no active ingredients

SECONDARY outcome

Timeframe: Randomization to Day 60

Median time until patient is discharged from hospital. Discharge is defined as a score of 1 or 2 in the WHO Ordinal Scale for Clinical Improvement. This is a 9 point ordinal scale with 0 indicating "No clinical or virological evidence of infection" and 8 indicating "Death".

Median time to hospital discharge and corresponding 95% C.I. were estimated from the Kaplan-Meier curves. In some cases the 95% confidence interval could not be calculated due primarily to censoring of data: Participants who are lost to follow-up as of the data analysis cutoff date are censored on the date of the participant's last known WHO Ordinal Scale for Clinical Improvement; Participants who die in the hospital are right censored at Day 60 or date of death, whichever is earlier.
