This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background Severe COVID-19 infection is associated with dysregulated immune response which, in a substantial minority of patients, results in cytokine release syndrome (CRS) and acute respiratory distress syndrome (ARDS). Inhibition of cytokines or cytokine-associated signal transduction is a promising strategy to ameliorate ARDS associated with CRS. We and others have previously shown that serum free LIGHT (TNFSF14) levels are markedly elevated in patients with COVID-19 pneumonia/ARDS10,11, suggesting that LIGHT neutralization may offer therapeutic benefit to COVID-19 ARDS patients. Methods We conducted a randomized, double-blind, placebo-controlled, multi-center, proof-of-concept clinical trial of CERC-002 in adults with mild to moderate ARDS associated with COVID-19 (n=83). Enrolled patients received a single dose of CERC-002 or placebo, in addition to standard of care that included high dose corticosteroids. The primary efficacy endpoint was alive and free of respiratory failure status through Day 28. Secondary outcomes included alive status at Day 28, free of invasive ventilation through Day 28, and serum free LIGHT levels. Results In patients hospitalized with COVID-19 associated pneumonia and mild to moderate (ARDS), CERC-002 increased the rate of alive and free of respiratory failure status through Day 28 as compared to placebo (83.9% vs 64.5%; p=0.044). Efficacy was highest in the prespecified subgroup of patients 60 years old and older (76.5% vs 47.1%; p=0.042), the population most vulnerable to severe complications and death with COVID-19 infection. Through both the initial 28-day and 60-day follow-up periods, reductions of approximately 50% in mortality were observed for CERC-002 compared to placebo (7.7% vs 14.3% at Day 28 and 10.8% vs 22.5% at Day 60). Importantly, this improvement was incremental to standard of care including high dose steroids and remdesivir 88.0% and 57.8%, respectively). In addition, serum LIGHT levels but not IL-6 levels were markedly reduced in patients treated with CERC-002. Conclusions The data presented herein demonstrate that CERC-002 markedly reduces the risk of respiratory failure and death incremental to standard of care including high dose corticosteroids and reduces LIGHT levels in patients with COVID-19 ARDS.
