Nanoviricides Platform Technology based NV-387 polymer Protects Remdesivir from Plasma-Mediated Catabolism in vitro: Importance of its increased lifetime for in vivo action

As of today seven coronaviruses were identified to infect humans, out of which only 4 of them belongs to beta family of coronavirus, like HCoV-HKU1, SARS-CoV-2, MERS-CoV and SARS-CoV. SARS family of viruses were known to cause severe respiratory disease in humans. SARS-CoV-2 infection causes pandemic COVID-19 disease with high morbidity and mortality. Remdesivir (RDV) is the only antiviral drug so far approved for Covid-19 therapy by FDA. However it’s efficacy is limited in vivo due to it’s low stability in presence of Plasma.

Here we show the stability of RDV encapsulated with our platform technology based polymer NV-387 (NV-CoV-2-R), in presence of Plasma in vitro in comparison to naked RDV when incubated in plasma. The potential use of this polymer in vivo will be discussed, here.
