Abstract Background With progressive accumulation of knowledge on SARS-CoV-2 infection clinical management, treatment guidelines recommended several options including remdesivir, a broad-spectrum antiviral. Given the evolving nature of coronavirus disease 2019, capturing the totality of scientific evidence from clinical trials and observational studies is critical to inform clinical decision making. We conducted a systematic literature review with meta-analysis to summarize the effectiveness of remdesivir among hospitalized adults. Methods We systematically searched MEDLINE, Embase and Cochrane Library databases for interventional and observational studies examining remdesivir efficacy. A rigorous double-reviewer approach was used for source identification, screening, data extraction and risk of bias assessment. A hierarchical random-effects model meta-analysis was used, with subgroup analyses for randomized controlled trials (RCTs) and real-world (RW) studies. Results From January 2019 to December 2023 >18 000 sources were screened, and 122 unique studies were identified, reporting on 25 174 participants in RCTs and 1 279 859 in RW studies. Remdesivir significantly increased survival in the overall population (odds ratio, 0.69 [95% confidence interval, .55–.86]; P = .001] across SARS-CoV-2 variants and disease severity levels: no supplemental oxygen (0.81 [.75–.88]), low-flow oxygen (0.71 [.64–.79]), high-flow oxygen (0.87 [.83–.91]), and invasive mechanical ventilation (0.78 [.68–.90]). Rehospitalization risk was significantly reduced in patients receiving remdesivir (odds ratio, 0.72 [95% confidence interval, .64–.81]). Conclusions Our comprehensive systematic literature review, capturing the totality of evidence, showed a significant survival benefit among patients hospitalized for SARS-CoV-2 infection and receiving remdesivir, across all disease severity levels. To assure that healthcare providers are aware of and deploy evidence-based optimal care, recommendations should rely on both RCT and RW data.

Abstract Background With progressive understanding of the natural history of COVID-19 and accumulation of knowledge on clinical management, treatment guidelines recommended several options including remdesivir (RDV), a broad-spectrum antiviral. Given the evolving nature of COVID-19, it is critical to capture the totality of scientific evidence to inform clinical decision making. We conducted a systematic literature review (SLR) to summarize the mortality endpoint for RDV among hospitalized adults throughout COVID-19 eras and contrasted with evidence informing treatment recommendations in clinical guidelines. Methods We systematically searched MEDLINE, Embase and Cochrane Library databases for interventional and observational studies examining RDV efficacy. Clinical trial registries, Cochrane COVID-19 Study Register, and conference abstracts were hand-searched (Fig1). Case reports and case studies were excluded. A review of most recent RDV recommendations across guidelines was conducted. Results From Dec ’19 to Dec ’22, 123 relevant publications were identified. In ’23, the evidence grew significantly, with 70 new publications. In total, 193 publications were evaluated, and 122 unique studies were included. While early randomized clinical trials (RCT) and small sample size observational studies did not universally demonstrate a significant difference in mortality in all severity groups of RDV-treated patients, real-world studies with larger sample sizes showed a significant impact across disease severity levels, regardless of COVID-19 era (Table1). Guideline recommendations for COVID-19 treatment with RDV are based on early RCTs (Table2) and most have not been updated (Fig2). Conclusion Our comprehensive evaluation of scientific literature indicates that evidence of RDV impact on mortality in hospitalized COVID-19 patients continued to grow and cover full range of disease severity. Guideline recommendations have not evolved in parallel which may explain differing recommendations in certain subgroups (e.g. IMV/ECMO). To assure that providers in the hospital setting are aware of and deploy evidence-based optimal care for patients with COVID-19, recommendations should rely on current evidence, including real-world data.
