  • The anti-SARS-CoV-2 spike protein monoclonal antibody (Xevudy/ Sotrovimab) is indicated for the treatment of mild-to-moderate COVID-19 in adults and pediatric patients who are at high risk for progression to severe disease.
  • Two systematic reviews/meta-analyses were reviewed, providing insights into the effectiveness and safety of sotrovimab in treating COVID-19.
  • A study focusing on solid organ transplant recipients (SOTR), a high-risk group, found that those with mild to moderate COVID-19 symptoms showed lower likelihoods of hospitalization, ICU admission, and mortality within 30 days after receiving sotrovimab compared to controls.
  • Another meta-analysis involving 27,429 patients demonstrated significant reductions in mortality rate, hospitalisation rate, need for mechanical ventilation and ICU admission among those treated with sotrovimab as opposed to non-recipients; however no significant difference was observed regarding disease progression or emergency department visits between both groups.
  • Despite its efficacy against both Delta and Omicron variants of COVID-19 according to one review's findings, there was no notable difference between adverse event incidence rates among individuals who received sotrovimab versus those who did not receive it.
  • Overall these documents suggest that Xevudy/Sotrovimab could be an effective treatment option reducing severity outcomes such as death or hospitalization especially amongst high risk populations like Solid Organ Transplant Recipients without increasing adverse events significantly.
