phase 3 inhaled novaferon study in hospitalized patients with moderate to severe covid-19

Conditions: Covid19

Summary: this study is a randomized, double-blind, multicenter, placebo-controlled trial to evaluate the safety and efficacy of a novel therapeutic agent, novaferon, in hospitalized adult patients diagnosed with covid-19. the study is comprised of two cohorts: * cohort a: this is a blinded safety lead-in comprising two arms. 40 patients will be randomized on a 1:1 basis to receive either novaferon or matched placebo via a commercial nebulizer, plus standard of care (soc) * cohort b: this is the main portion of the study, which comprises two arms. up to 874 patients will be randomized on a 1:1 basis to receive either novaferon or matched placebo via a commercial nebulizer, plus soc
