Here's a larger study testing whether Hydroxychloroquine can prevent covid 19 in hospital workers and others exposed to the virus
Dr. Boulware is overseeing a clinical trial at the U to determine whether hydroxychloroquine is effective in preventing the coronavirus. They currently have about 1500 front line medical workers and first responders nationwide taking part. The participants take a safe dose once or twice a week, and researchers are checking whether those people contract COVID-19.
The U will be the first to publish results of such a study, Boulware said. They expect to see preliminary data in about a month. But he adds they still want to get about 3000 participants and will finish the study sooner with more participants.

Boulware says lab experiments have found the drug can prevent the coronavirus from infecting cells. But they need to find out if the same is true for people who take the pill.
