  • https://today.tamu.edu/2021/08/25/texas-am-researcher-new-drug-could-be-game-changer-against-covid-19

Sorrento’s decision to exercise its option immediately is based on promising preclinical data for the lead compound MPI8, which has highly potent broad spectrum antiviral activity against SARS-CoV-2 and all major Variants of Concern (VoCs) (Alpha, Beta, Delta and Gamma). Based on initial in vitro data, MPI8 demonstrated superior antiviral activity in a direct comparison with a current phase 3 study of oral antiviral agents (EIDD2801). Based on the Plague Reduction Neutralization Test (PRNT) IC50 data from live viruses infecting Vero E6 cells, MPI8 showed about ten times (10x) higher antiviral activity than EIDD-2801 against SARS-CoV-2 and its alpha ( UK) and Delta (Indian) VoCs and three to seven times (3-7x) higher antiviral effectiveness against Beta (South Africa, 3x) and Gamma (Brazil / Japan, 6-7x) VoCs.

Sorrento expects to complete additional preclinical studies in the coming weeks, including a head-to-head comparison with other late-stage clinical candidates, and will publish its preliminary results in a pre-print publication.
