Journal: Discovery of Nirmatrelvir Resistance Mutations in SARS-CoV-2 3CLpro: A Computational-Experimental Approach. (Pubmed Central) - Nov 28, 2023 Our findings suggest that FEP can be a valuable tool in proactively monitoring the emergence of resistant strains and guiding the design of future inhibitors with reduced susceptibility to drug resistance. As nirmatrelvir is currently widely used for treating COVID-19, this research has important implications for surveillance efforts and antiviral development.

Retrospective data, Review, Journal: Evaluation of oral small molecule drugs for the treatment of COVID-19 patients: a systematic review and network meta-analysis. (Pubmed Central) - Nov 27, 2023 For prespecified safety outcomes, SUCRA values ranked VV116 (OR = 0.09, 95% CI: 0.00-2.07: SUCRA 0.86) as the most beneficial intervention for the prevention of serious adverse events. When compared to other antiviral medications, paxlovid can reduce the mortality and hospitalization of COVID-19 patients.

(Pubmed Central) - Nov 21, 2023 As per current recommendations, their use is suggested in patients with mild to moderate symptoms who are at high risk of developing severe disease. Nevertheless, limited data exist regarding their efficacy in specific subpopulations, such as immunocompromised patients, those with severe kidney disease, pregnant women, and children.

Preclinical, Journal: Activation of PXR causes drug interactions with Paxlovid in transgenic mice. (Pubmed Central) - Nov 16, 2023 We found that PXR activation increased CYP3A4/5 expression, accelerated NMV metabolism, and reduced the systemic exposure of NMV. In summary, our work demonstrated that PXR activation can cause drug interactions with Paxlovid, suggesting that PXR-activating drugs and herbs should be used cautiously in COVID-19 patients receiving Paxlovid.

Journal: Paxlovid as a potential treatment for long COVID. (Pubmed Central) - Nov 14, 2023 The first prospective, randomized study of the RECOVER research initiative, RECOVER-Vital, will evaluate the SARS-CoV-2 antiviral nirmatrelvir/ritonavir (Paxlovid) as a potential treatment for long COVID. This manuscript explores what is known about Paxlovid to treat and prevent long COVID and examines the rationale for addressing this condition with an antiviral agent.

(Pubmed Central) - Nov 6, 2023 In routine care of non-hospitalised high-risk adult patients with COVID-19 in England, no substantial difference in the risk of severe COVID-19 outcomes was observed between those who received nirmatrelvir/ritonavir and sotrovimab between February and November 2022, when Omicron subvariants BA.2, BA.5, or BQ.1 were dominant.

Review, Journal: SARS-CoV-2: The Virus, Its Biology and COVID-19 Disease-Counteracting Possibilities. (Pubmed Central) - Nov 5, 2023 Also, the possibility to fight this virus with recently available drugs (Veklury, Lagevrio and Paxlovid) will be discussed. All these data clearly argue that SARS-CoV-2 variants still exhibit a dangerous potential-although with a lower case fatality rate-and that vaccination in combination with drug intake upon infection may help to lower the risk of developing chronic or temporary autoimmune diseases.

Observational data, Journal: COVID-19 early curative treatments in kidney transplant recipients: is it really reasonable at the Omicron era? (Pubmed Central) - Nov 5, 2023 There was no difference in outcome according to early therapeutic management: n/r, sotrovimab or no specific treatment. Our study both underlines a decreased severity of Omicron COVID-19 in KTRs (probably related to vaccinal immunity and decreased virulence of Omicron) and a potential severe adverse effects with n/r.

Impact of COVID-19 in Patients with Chronic Lymphocytic Leukemia Treated with Venetoclax: A Possible Role of the Association to Anti-CD20 Antibody? a Multicentre Seifem Study (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_4221; The retrospective multicenter study included CLL patients treated since 2017 with venetoclax single agent until progression or toxicity or venetoclax plus anti-CD20 antibody (mainly rituximab as part of VR protocol for 24 months in relapsed/refractory patients or obinutuzumab as part of VO protocol for 12 months in untreated patients)...Prophylaxis with tixagevimab/cilgavimab was administered in less than 20% of the patients...Remdesivir was chosen as treatment in 48.9%, nirmatrelvir/ritonavir in 21.3%...The analysis found over a third of patients infected by SARS-CoV-2, in 57% of the cases the infection was grade 1-2 with a mortality rate of almost 10%, but higher if COVID-19 was of grade 3-4 (18.2%). We confirmed the association of anti-CD20 antibody to venetoclax as a risk factor for SARS-CoV-2 infection and mortality rate in patients with CLL and severe COVID-19.

At the current stage of the COVID-19 pandemic, the use of mAbs developed against early SARS-CoV-2 variants has little prospect. Specific antiviral drugs retain their activity, but further monitoring is needed to assess the risk of their efficacy being reduced and adjust recommendations for their use.
