On Feb. 12, 2021, the NIH announced that enrollment had begun to test additional investigational drugs in the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) program. ACTIV is a public-private partnership program to create a coordinated research strategy that prioritizes and speeds development of promising COVID-19 treatments and vaccines.

The new agents entering the randomized, placebo-controlled study are part of ACTIV-2, an adaptive trial designed to test investigational agents in non-hospitalized adult volunteers experiencing mild to moderate COVID-19 symptoms. ACTIV-2 was sponsored by the NIAID.
