With outbreaks gaining steam in many countries, the global COVID-19 total passed 200,000 reported cases today, and the World Health Organization (WHO) announced a large international clinical trial to test five treatment regimens.
Multiple small trials using different methods may not yield strong evidence needed to reveal which ones can save lives. So, WHO has organized a large international study—called the SOLIDARITY trial—to get more robust data.
The streamlined randomized trial can be adjusted based on countries' availability of the drugs and can be adjusted to include other arms.
