Abstract
Background: Many recent studies have investigated the role of drug interventions for coronavirus disease 2019 (COVID-19) infection. However, an important question has been raised about how to select the effective and secure medications for COVID-19 patients. The aim of this analysis was to assess the efficacy and safety of the various medications available for severe and non-severe COVID-19 patients based on randomized placebo-controlled trials (RPCTs).Methods: We did an updated network meta-analysis. We searched the databases from inception until July 31, 2021, with no language restrictions. We included RPCTs comparing 49 medications and placebo in the treatment of severe and non-severe patients (aged 18 years or older) with COVID-19 infection. We extracted data on the trial and patient characteristics, and the following primary outcomes: all-cause mortality, the ratios of virological cure, and treatment-emergent adverse events. Odds ratio (OR) and their 95% confidence interval (CI) were used as effect estimates.Results: From 3,869 publications, we included 61 articles related to 73 RPCTs (57 in non-severe COVID-19 patients and 16 in severe COVID-19 patients), comprising 20,680 patients. The mean sample size was 160 (interquartile range 96–393) in this study. The median duration of follow-up drugs intervention was 28 days (interquartile range 21–30). For increase in virological cure, we only found that proxalutamide (OR 9.16, 95% CI 3.15–18.30), ivermectin (OR 6.33, 95% CI 1.22–32.86), and low dosage bamlanivimab (OR 5.29, 95% CI 1.12–24.99) seemed to be associated with non-severe COVID-19 patients when compared with placebo, in which proxalutamide seemed to be better than low dosage bamlanivimab (OR 5.69, 95% CI 2.43–17.65). For decrease in all-cause mortality, we found that proxalutamide (OR 0.13, 95% CI 0.09–0.19), imatinib (OR 0.49, 95% CI 0.25–0.96), and baricitinib (OR 0.58, 95% CI 0.42–0.82) seemed to be associated with non-severe COVID-19 patients; however, we only found that immunoglobulin gamma (OR 0.27, 95% CI 0.08–0.89) was related to severe COVID-19 patients when compared with placebo. For change in treatment-emergent adverse events, we only found that sotrovimab (OR 0.21, 95% CI 0.13–0.34) was associated with non-severe COVID-19 patients; however, we did not find any medications that presented a statistical difference when compared with placebo among severe COVID-19 patients.Conclusion: We conclude that marked variations exist in the efficacy and safety of medications between severe and non-severe patients with COVID-19. It seems that monoclonal antibodies (e.g., low dosage bamlanivimab, baricitinib, imatinib, and sotrovimab) are a better choice for treating severe or non-severe COVID-19 patients. Clinical decisions to use preferentially medications should carefully consider the risk-benefit profile based on efficacy and safety of all active interventions in patients with COVID-19 at different levels of infection.
Highlights
Coronavirus disease 2019 (COVID-19) is an unprecedented global life-threatening pandemic
For change in all-cause mortality (ACM), we found that proxalutamide, imatinib, and baricitinib were more efficacious than placebo for patients with nonsevere COVID-19 infection; we only found that immunoglobulin gamma (IG) was associated with decreased ACM in severe COVID-19 patients
Of all the included active interventions, only proxalutamide, ivermectin, and low dosage bamlanivimab (LDB) might be more efficacious than placebo for the virological cure (VC) ratio in non-severe
Summary
Coronavirus disease 2019 (COVID-19) is an unprecedented global life-threatening pandemic. Though COVID-19 has a relatively low mortality rate, it can cause a highly lethal rate in high-risk patients [2, 3] It is unclear how a specific, effective, and secure therapy for severe or non-severe COVID-19 infection is selected [4]. An important question has been raised about how to select the effective and secure medications for COVID-19 patients The aim of this analysis was to assess the efficacy and safety of the various medications available for severe and non-severe COVID-19 patients based on randomized placebocontrolled trials (RPCTs). Conclusion: We conclude that marked variations exist in the efficacy and safety of medications between severe and non-severe patients with COVID-19 It seems that monoclonal antibodies (e.g., low dosage bamlanivimab, baricitinib, imatinib, and sotrovimab) are a better choice for treating severe or non-severe COVID-19 patients.
