COVID-19 Treatment Study

Diagnosed with Covid-19 and want to feel better faster?

If you have been recently diagnosed with COVID-19, you may be interested in the OakTree Study. This clinical research study is testing the effectiveness and safety of an investigational medication for COVID-19 called GS-5245. Researchers want to see if GS-245 can shorten the length of time you have symptoms.

Who can join the study?

To be considered for the study, you must:

  • Be 12 to 64 years of age.
  • Have tested positive for COVID-19 in the last 3 days.
  • Have had COVID-19 symptoms for no more than 3 days.
  • NOT be at risk for developing serious disease.
  • NOT be currently hospitalized or require hospitalization.

What happens during the study?

The study lasts about 90 days with about 9 visits for tests and health checks.


If you qualify, you will be placed by chance into a group to take either a GS-5245 or a placebo tablet by mouth twice a day for 5 days.


Your participation in this study can help advance COVID-19 research to find more safe and effective treatments. Being in the study is voluntary and you can stop participating at any time.
