ABSTRACT
Introduction
VV116 is a chemically-modified version of the antiviral remdesivir with oral bioavailability and potent activity against SARS-CoV-2.
Areas Covered
The optimal treatment of standard-risk outpatients who develop mild-to-moderate COVID-19 is controversial. While several therapeutic are currently recommended, including nirmatrelvir–ritonavir (Paxlovid), molnupiravir, and remdesivir, these treatments have substantial drawbacks, including drug-drug interactions and questionable efficacy in vaccinated adults. Novel therapeutic options are urgently needed.
Expert Opinion
On 28 December 2022, a phase 3, observer-blinded, randomized trial was published evaluating 771 symptomatic adults with mild-to-moderate COVID-19 with a high risk of progression to severe disease. Participants were assigned to receive a 5-day course of either Paxlovid)\, which is recommended by the World Health Organization for treating mild-to-moderate COVID-19, or VV116 and the primary end point was the time to sustained clinical recovery through day 28. Among study subjects, VV116 was found to be noninferior to Paxlovid with respect to the time to sustained clinical recovery and with fewer safety concerns. This manuscript examines what is known about VV116 and explores how this novel treatment option may be used in the future to address the ongoing SARS-CoV-2 pandemic.
Article highlights
The optimal treatment of standard-risk outpatients who develop mild-to-moderate COVID-19 is controversial.
Paxlovid is recommended for high-risk outpatients, but its use in standard-risk adults is uncertain.
VV116 is a chemically-modified version of the antiviral remdesivir with oral bioavailability and potent activity against SARS-CoV-2.
A recent phase 3, observer-blinded, randomized trial of symptomatic adults with mild-to-moderate COVID-19 with a high risk of progression to severe disease found that VV116 was noninferior to Paxlovid with respect to time to sustained recovery.
