Neutralizing antibodies (NAbs) that target key domains of the spike protein in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may have therapeutic value because of their specificity. Depending on the targeted epitope, single agents may be effective, but combined treatment involving multiple NAbs may be necessary to prevent the emergence of resistant variants.
This article highlights the accelerated regulatory processes established to facilitate the review and approval of potential therapies. An overview of treatment approaches for SARS-CoV-2 infection, with detailed examination of the preclinical and clinical evidence supporting the use of NAbs, is provided. Finally, insights are offered into the potential benefits and challenges associated with the use of these agents.
NAbs offer an effective, evidence-based therapeutic intervention during the early stages of SARS-CoV-2 infection when viral replication is the primary factor driving disease progression. As the pandemic progresses, appropriate use of NAbs will be important to minimize the risk of escape variants. Ultimately, the availability of effective treatments for COVID-19 will allow the establishment of treatment algorithms for minimizing the substantial rates of hospitalization, morbidity (including long COVID) and mortality currently associated with the disease.
针对严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)刺突蛋白关键结构域的中和抗体(NAb)因其特异性可能具有治疗价值。根据靶向表位的不同,单一药物可能有效,但为了防止耐药变异的出现,可能需要联合使用多种 NAb 进行治疗。
本文强调了为促进潜在治疗方法的审查和批准而建立的加速监管程序。概述了 SARS-CoV-2 感染的治疗方法,并详细检查了支持使用 NAb 的临床前和临床证据。最后,探讨了使用这些药物的潜在益处和挑战。
在 SARS-CoV-2 感染的早期阶段,病毒复制是驱动疾病进展的主要因素,NAb 提供了一种有效且有证据支持的治疗干预措施。随着大流行的发展,适当使用 NAb 对于降低逃逸变异的风险非常重要。最终,有效的 COVID-19 治疗方法的出现将允许制定治疗方案,以最大程度地降低目前与该疾病相关的住院率、发病率(包括长 COVID)和死亡率。
