Phase I study, and dosing regimen selection for a pivotal COVID-19 trial of GST-HG171
This study is aimed to evaluate the safety, tolerability, and pharmacokinetics (PK), as well as to select an appropriate dosing regimen for the pivotal clinical trial of GST-HG171, an orally bioavailable, potent, and selective 3CL protease inhibitor by a randomized, double-blind, and placebo-controlled phase I trial in healthy subjects. We conducted a Ph1 study involving 78 healthy subjects to assess the safety, tolerability, and PK of single ascending doses (150-900 mg) as well as multiple ascending doses (MADs) (150 and 300 mg) of GST-HG171. Additionally, we examined the food effect and drug-drug interaction of GST-HG171...

Optimizing COVID-19 treatment in immunocompromised patients: early combination therapy with remdesivir, nirmatrelvir/ritonavir and sotrovimab
Morbidity and mortality are higher in immunocompromised patients affected by COVID-19 than in the general population. Some authors have successfully used antiviral combination, but never in the early phase of ... (Source: Virology Journal)

Simultaneous pharmacokinetic modeling of unbound and total darunavir with ritonavir in adolescents: a substudy of the SMILE trial
Antimicrob Agents Chemother. 2023 Dec 11:e0100423. doi: 10.1128/aac.01004-23. Online ahead of print.ABSTRACTDarunavir (DRV) is an HIV protease inhibitor commonly used as part of antiretroviral treatment regimens globally for children and adolescents. It requires a pharmacological booster, such as ritonavir (RTV) or cobicistat. To better understand the pharmacokinetics (PK) of DRV in this younger population and the importance of the RTV boosting effect, a population PK substudy was conducted within SMILE trial, where the maintenance of HIV suppression with once daily integrate inhibitor + darunavir/ritonavir in children and...

Nirmatrelvir/ritonavir for COVID-19: an overview of systematic reviews
ConclusionsThere is low to moderate certainty of evidence from SRs that nirmatrelvir/ritonavir reduces mortality, clinical progression and hospitalization rate in COVID-19 patients compared with controls, without increasing the occurrence of overall and serious adverse events. Based on the overall methodological assessment, on average we can have high confidence in the quality of results generated by the SRs. (Source: Journal of Antimicrobial Chemotherapy)

Prevalence and risk factors of metabolic syndrome in Ethiopia: describing an emerging outbreak in HIV clinics of the sub-Saharan Africa - a cross-sectional study
Conclusion Our study revealed 38% of the participants had MetS indicating considerable cardiovascular disease (CVD) risks. Independent risk factors for MetS were BMI≥25 kg/m2, efavirenz and lopinavir/ritonavir-based cART, female sex and age ≥45 years. In addition to prevention, CVD risk stratification and management will reduce morbidity and mortality in people with HIV infection. (Source: BMJ Open)

Biden wants NIH to have ‘march-in’ power to override patent rights for high-priced drugs
President Joe Biden today stepped into a long-running debate about whether the National Institutes of Health (NIH) has legal authority to override an exclusive patent license granted to drug developers if they charge too much for treatments that relied on agency-funded research. In draft policy guidance, the Biden administration says federal agencies would be able to use so-called “march-in” rights when a company is not charging a “reasonable” price for a product. The “ proposed framework ” was released today as part of other White House actions aimed at the high drug prices that have ...

Strategies to Mitigate the Drug-Drug Interaction between Nirmatrelvir/Ritonavir and Tacrolimus in Allogeneic Hematopoietic Stem Cell Transplant Recipients on Azole Antifungals: Results of a Case Series
CONCLUSION: NIM/r-tacrolimus is a serious drug-drug interaction which can be mitigated by early discontinuation of tacrolimus and azole antifungals, close monitoring, and reinitiation of tacrolimus and antifungal 48-72 h after completion of therapy.PMID:38059378 | DOI:10.1159/000534445 (Source: Acta Haematologica)
