COVID-19 Studies from the World Health Organization Database

US National Library of Medicine (regularly updated)

This is a database of ongoing and completed COVID-19 studies listed on the World Health Organization’s International Clinical Trials Registry Platform (WHO ICTRP). Information in the WHO ICTRP comes from clinical trial databases maintained by other countries or regions of the world. COVID-19 studies listed on are not included in this list, but can be found using the linked search for COVID-19. To give researchers and the public rapid access to studies on COVID-19 in other countries, update this list weekly. You can also access the information directly from the WHO ICTRP.
