A new clinical treatment trial launched Friday and UW Medicine researchers are looking for COVID-19 patients to test the effectiveness of anti-malaria drug hydroxychloroquine. UW researchers want to enroll 630 people who currently have the COVID-19 virus. Researchers say this particular study looks at COVID-19 patients who do not need to go to the hospital yet. Researchers are testing two combinations. One is hydroxychloroquine. The other is hydroxychloroquine plus azithromycin. Researchers are also using a placebo. UW Medicine is looking for patients in cities nationwide including Boston, Chicago, and New York.
