Descriptive Information
Brief Title  ICMJE Study of Isoquercetin (IQC-950AN) Plus Standard of Care Versus Standard of Care Only for the Treatment of COVID-19
Official Title  ICMJE An Open-Label Randomized Study of Isoquercetin (IQC-950AN) Plus Standard of Care Versus Standard of Care Only for the Treatment of 2019 Novel Coronavirus Disease (COVID-19)
Brief Summary This is an open-label, randomized, multi-centre study where hospitalized subjects will be randomized in a 2:1 ratio to receive Isoquercetin (IQC-950AN) in addition to standard of care or standard of care only for 28 days following confirmation of a COVID-19 infection.
Detailed Description

The primary purpose of this randomized study will be to evaluate the effect of Isoquercetin (IQC-950AN) treatment on disease progression (defined as ≥ 6 on the World Health Organization (WHO) clinical progression scale) when given to subjects with confirmed COVID-19 in addition to standard of care. The secondary purpose of this study is to evaluate the effect of Isoquercetin (IQC-950AN) treatment on the reduction of severe acute respiratory coronavirus 2 (SARS-CoV-2) viral titers in these subjects and their recovery. In addition, certain parameters which may help elucidate the mechanism of action (sLDLR, PCSK9, sACE2, D-dimers and CRP) will be followed. The safety of Isoquercetin (IQC-950AN) will be evaluated at each visit. Subjects will be randomized to receive treatment for 28 days and then will return 30 days following the discontinuation of treatment for a final safety visit.

The results of this study will be used to design an adequately powered randomized controlled pivotal study to evaluate the efficacy and safety of Isoquercetin (IQC-950AN) in all or a subset of subjects with confirmed COVID-19.
