Amubarvimab/romlusevimab for COVID-19: real-time meta analysis of 4 studies | |
| Significantly lower risk is seen for viral clearance. 2 studies from 2 independent teams (both from the same country) show significant benefit. Meta analysis using the most serious outcome reported shows 25% [-70‑66%] lower ris.. | ||

et al., Heliyon, doi:10.1016/j.heliyon.2024.e37663 | Effect of amubarvimab-romlusevimab for treatment of severe COVID-19 in intensive care units: A retrospective cohort study |
| 46% lower mortality (p=0.06) and 4% improved viral clearance (p=0.89). Retrospective 121 severe ICU COVID-19 patients in China showing lower 28-day mortality and ICU mortality with amubarvimab-romlusevimab treatment compared to no antiviral treatment. No significant differences were found in viral conversion.. | ||

| 91% lower mortality (p=0.006), 20% higher PASC (p=0.39), 61% lower hospitalization (p=0.0008), and 67% lower combined mortality/hospitalization (p<0.0001). RCT 780 high-risk non-hospitalized COVID-19 patients showing significantly lower risk of hospitalization or death through 36 weeks, but no significant difference in long COVID with amubarvimab/romlusevimab treatment compared to placebo. | ||
