Molnupiravir, EIDD-2801/MK-4482, the prodrug of active antiviral ribonucleoside analog ß-d-N4-hydroxycytidine (NHC; EIDD-1931), has activity against a number RNA viruses including severe acute respiratory syndrome coronavirus 2, coronavirus, Middle East and seasonal pandemic influenza viruses.Single multiple doses molnupiravir were evaluated in this first-in-human, phase 1, randomized, double-blind, placebo-controlled study healthy volunteers, which included evaluation effect food on...

There is an urgent need for effective, oral, direct-acting therapeutic to block transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and prevent progression disease 2019 (COVID-19). In a phase 2a double-blind, placebo-controlled, randomized, multicenter clinical trial, we evaluated the safety, tolerability, antiviral efficacy nucleoside analog molnupiravir in 202 unvaccinated participants with confirmed SARS-CoV-2 infection symptom duration <7 days. Participants...

Abstract Background Easily distributed oral antivirals are urgently needed to treat coronavirus disease-2019 (COVID-19), prevent progression severe illness, and block transmission of acute respiratory syndrome 2 (SARS-CoV-2). We report the results a Phase 2a trial evaluating safety, tolerability, antiviral efficacy molnupiravir in treatment COVID-19 ( ClinicalTrials.gov NCT04405570 ). Methods Eligible participants included outpatients with confirmed SARS-CoV-2 infection symptom onset within...

Abstract Molnupiravir, EIDD-2801/MK-4482, the prodrug of ribonucleoside analog ß-d-N4-hydroxycytidine (NHC), has activity against a number RNA viruses including severe acute respiratory syndrome coronavirus 2, coronavirus, Middle East seasonal and pandemic influenza viruses, syncytial virus. Single multiple doses molnupiravir were evaluated in this first-in-human, phase 1, randomized, double-blind, placebo-controlled study healthy volunteers, which included evaluation effect food on...

Abstract Meaningful metrics of antiviral activity are essential for determining the efficacy therapeutics in human clinical trials. Molnupiravir (MOV) is a broadly acting nucleoside analog prodrug that acts as competitive alternative substrate SARS-CoV-2 RNA-dependent RNA polymerase (RdRp). We developed an assay, Culture-PCR, to better understand impact MOV therapy on infectious SARS-CoV-2. Culture-PCR revealed eliminated virus within 48 hours nasopharyngeal compartment, upper airway...

Abstract Background While SARS-CoV-2 infectious virus isolation in outpatients with COVID-19 has been associated viral RNA levels and symptom duration, little is known about the host, disease determinants of detection. Methods adult were enrolled within 7 days onset. Clinical symptoms recorded via patient diary. Nasopharyngeal swabs collected to quantitate by reverse transcriptase polymerase chain reaction for Vero E6-cells. antibodies measured serum using a validated ELISA assay. Results...
