41st treatment shown to reduce risk in May 2022, now with p = 0.0066 from 19 studies, recognized in 33 countries. Efficacy is variant dependent.
Lower risk for mortality, hospitalization, and cases.
No treatment is 100% effective. Protocols combine treatments.

FDA adverse event reporting analysis for bebtelovimab, tixagevimab/cilgavimab, and sotrovimab, showing distinct safety profiles with concerning adverse events for each drug. Bebtelovimab showed the highest associations with gastrointestinal disorders (nausea) and nervous system disorders (dizziness), including severe eye complications like acute macular neuroretinopathy. Tixagevimab/cilgavimab was associated with multiple cardiovascular events including thrombosis, heart failure, and arrhythmias. Sotrovimab showed the strongest correlations with skin reactions, infusion-related hypersensitivity reactions, and anaphylactic shock. Authors hypothesize that sotrovimab's broader cross-coronavirus neutralization capacity may explain its stronger immunoreactivity compared to the other monoclonal antibodies.
Efficacy is variant dependent. In Vitro research suggests a lack of efficacy for omicron BA.2.75.2, BA.4.6, BQ.1.11, BA.5, BA.2.75, XBB2,3, XBB.1.53, ХВВ.1.9.13, XBB.1.9.3, XBB.1.5.24, XBB.1.16, XBB.2.9, BQ.1.1.45, CL.1, and CH.1.14.
Study covers sotrovimab, bebtelovimab, and tixagevimab/cilgavimab.

OBJECTIVE: Bebtelovimab (BEB), Tixagevimab/Cilgavimab (TIX/CIL), and Sotrovimab (SOT) are important agents against the severe acute respiratory syndrome coronavirus 2-Omicron strain. However, due to their short duration of application, little is known about their safety profiles. This research aimed to explore the safety profile of these monoclonal antibodies (mAbs) via real-world evidence databases and data mining tools. MATERIALS AND METHODS: Safety reports were retrieved from the database of the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System from April 2022 to March 2023. To detect the safety signal, the disproportionality analysis was performed using the reporting odds ratio method. RESULTS: SOT had the greatest proportion of "skin and subcutaneous tissue disorders" and "disorders of investigations"; BEB showed significant associations with "gastrointestinal disorders" and "nervous system disorders"; TIX/CIL had the weakest correlation with "skin and subcutaneous tissue disorders" and "general disorders and administration site conditions". Furthermore, there were still other signals related to nervous system disorders, gastrointestinal disorders only caused by BEB. TIX/ CIL has been reported solely to be associated with multiple types of cardiovascular disorders. As for SOT alone, signals were strongly related to infusion reactions and hypersensitivity. CONCLUSIONS: In summary, SOT may be unsuitable for allergic patients and may lead to abnormal test results. BEB showed the highest correlations with gastrointestinal and neuropsychiatric events. In addition, its infusion reactions should also be noted. TIX/CIL can lead to a variety of cardiovascular events.
