With many asking questions about existing vaccine and/or therapeutic clinical trials, the Doximity Editorial team has compiled a list of relevant and ongoing or planned studies found on clinicaltrials.gov. Above, you will find the number of studies being conducted in the U.S. (blue) and outside the U.S. (red) since the first cluster of COVID-19 cases reported by Chinese officials on December 31, 2019. 

*Data source: www.clinicaltrials.gov

The majority (62.5%) of clinical trials in the U.S. are investigating treatment options for COVID-19 (see graph above). Many of the trials represented are investigating repurposed drugs. Gilead’s remdesivir, an intravenous antiviral treatment, is currently in a phase 3 clinical trial and in recent news, they gave up orphan status which allowed for the earlier release of generic competitors. A phase 3 clinical trial has also been launched testing the effectiveness of hydroxychloroquine, a drug brought to public attention by the President. Use of convalescent plasma collected from individuals who have recovered from COVID-19 as a method of providing viral antibodies to patients has also garnered attention from the FDA. In addition to these high profile drugs, studies are also investigating the therapeutic potential of other agents such as aviptadil, CD24Fc, and stem cell therapy. For information about recommended treatments and access to remdesivir and hydroxychloroquine, check out the CDC’s guide to current therapeutic options for COVID-19. 

There are also notable efforts to develop novel therapies and vaccines for COVID-19. For commentary on these investigations worldwide, STAT's guide is a good resource.

For individual reference, we have compiled a list of all clinical trials following this article separated by geographic location. As this health crisis develops, Doximity hopes to be a source of relevant and useful information for those on the front lines. 

Thank you,
