DAS181 for STOP COVID-19

The first stage is randomized, double-blind study to confirm the optimal dose of the study. Twenty-two (n=22) subjects with COVID-19 and clinically significant impairment of respiratory function will be enrolled to evaluate the two dosing regimens (4.5mg-q.d or 4.5mg-b.i.d) of DAS181. At the end of Stage 1, the Sponsor will evaluate the dose regimen based on the safety and efficacy assessments of the data. An optimal dose will be selected to proceed to Stage 2. The second stage is a randomized, placebo-controlled and double-blind study to expand enrollment with an additional eighty-two (n=82) subjects to provide adequate power to potentially demonstrate statistically significant therapeutic efficacy.
