Brief Summary
Evusheld(AZD7442) is a combination of 2 human long-acting antibodies, which was selected for maximal potency and demonstrated synergistic neutralization of SARS-CoV-2 in vitro. PROVENT is a Phase III study in participants at an increased risk for inadequate response to COVID-19 vaccine, an increased risk of exposure to SARS-CoV-2 or both. The study met the primary endpoint of reduction in the incidence of symptomatic Coronavirus disease 2019 (COVID-19) with tixagevimab/cilgavimab (TIXA/CILGA) compared with placebo, risk reduction 76.7% (95% CI, 46.0-90.0), in 5172 patients who did not have a Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Reverse transcription polymerase chain reaction (RT-PCR) positive COVID-19 infection at baseline. Although the PROVENT trial was invaluable in demonstrating AZD7442's ability to prevent symptomatic infection, it was conducted in highly controlled environments using a rigorous protocol, which does not accurately reflect the patient experience in clinical practice. Furthermore, the sample size of Asian population in phase 3 clinical trials is small (110 subjects in AZD7442 group and 60 subjects in placebo group), and there is very limited clinical trial/real-world data in Chinese population is reported. Therefore, this current study aims to describe the utilisation and clinical outcomes of AZD7442 in Chinese population for pre-exposure prophylaxis.
