The testing program at this stage is enrolling 2,660 healthy adult participants aged 18 and older who are currently in contract or have been exposed to the virus especially those who live with a confirmed COVID positive person.
The participants will be asked randomly to take either the drug or placebo orally twice daily for 5 or 10 days.
