Oral Nirmatrelvir–Ritonavir as Postexposure Prophylaxis for Covid-19 | NEJM Clinical trials of treatments for coronavirus disease 2019 (Covid-19) have not shown a significant benefit of postexposure prophylaxis. We conducted a phase 2–3 double-blind trial to assess the eff...

#Evidence that #nirmatrelvir/ #ritonavir (#Paxlovid) is not effective as post-exposure prophylaxis for #COVID19 after #SARSCoV2 infection.
#MedSky 🧪

RAY1216 shows antiviral activities against #SARSCoV2 variants comparable to those of nirmatrelvir. It also shows improved pharmacokinetics in vivo ,suggesting that RAY1216 could be used without #ritonavir , which is co-administered with #nirmatrelvir.

Exploring diverse reactive warheads for the design of SARS-CoV-2 main protease inhibitors SARS-CoV-2 main protease (Mpro) is a validated antiviral drug target of nirmatrelvir, the active ingredient in Pfizer's oral drug Paxlovid. Drug-drug …

No cysteine protease inhibitors had been approved by @US_FDA before #Pfizer's #Paxlovid which contains the Mpro inhibitor #nirmatrelvir & the metabolic enhancer #ritonavir. 🔑 to the success of #nirmatrelvir is the choice of nitrile as the reactive warhead

Lopinavir–ritonavir in patients admitted to hospital with COVID-19 (RECOVERY): a randomised, controlled, open-label, platform trial In patients admitted to hospital with COVID-19, lopinavir–ritonavir was not associated with reductions in 28-day mortality, duration of hospital stay, or risk of progressing to invasive mechanical ventilation or death. These findings do not support the use of lopinavir–ritonavir for treatment of patients admitted to hospital with COVID-19.

L'association #lopinavir #ritonavir ne marche pas dans la #Covid_19 .
Avec des IC50 de 10 µM dans le (mauvais) modèle des cellules vero et 20 µM sur cellule humaine... il n'y avait aucune chance
