Background

Avoralstat is an inhibitor of kallikrein, a serine protease involved in the contact activation system.¹ It inhibits kallikrein activity in isolated human plasma (EC₅₀s = 1.14-11.1 nM). Avoralstat also inhibits transmembrane serine protease 2 (TMPRSS2; IC₅₀ = 2.73 nM), a serine protease required for entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into host cells.^2,3 It inhibits SARS-CoV-2 pseudovirus entry into Calu-3 2B4 cells (EC₅₀ = 0.7 ?M).² Avoralstat (30 mg/kg) reduces or prevents the accumulation of lung viral titers in mouse models of SARS-CoV-2 infection or prophylaxis, respectively, using Ad5-hACE2 mice that are sensitive to SARS-CoV-2 infection.
