Abstract

Background

The COVID-19 pandemic has spurred significant endeavors to devise treatments to combat SARS-CoV-2. A limited array of small-molecule antiviral drugs, specifically monoclonal antibodies and interferon therapy, have been sanctioned to treat COVID-19. These treatments typically necessitate administration within ten days of symptom onset. There have been reported reductions in the effectiveness of these medications due to mutations in non-structural protein genes, particularly against Omicron subvariants. This underscores the pressing requirement for healthcare systems to continually monitor pathogen variability and its impact on the efficacy of prevention and treatments.

Aim

This review aimed to comprehend the therapeutic benefits and recent progress of nMAbs for preventing and treating the Omicron variant of SARS-CoV-2.

Results and Discussion

Neutralizing monoclonal antibodies (nMAbs) provide a treatment avenue for severely affected individuals, especially those at high risk for whom vaccination is not viable. With their specific epitope affinity, they pose no significant risk of severe adverse effects. The degree of reduction in neutralization varies significantly across different monoclonal antibodies and variant combinations. For instance, Sotrovimab maintained its neutralization effectiveness against Omicron BA.1, but exhibited diminished efficacy against BA.2, BA.4, BA.5, and BA.2.12.1.

Conclusion

Bebtelovimab has been observed to preserve its efficacy against all subtypes of the Omicron variant. Subsequently, WKS13, mAb-39, 19n01, F61-d2 cocktail, ., have become effective. This review has highlighted the therapeutic implications of nMAbs in SARS-CoV-2 Omicron treatment and the progress of COVID-19 drug discovery.
