Pre-exposure Prophylaxis with Tixagevimab-cilgavimab did not Reduce Severity of COVID-19 in Lung Transplant Recipients with Breakthrough Infection

I nfection with the severe acute respiratory syndrome coro- navirus 2 (SARS-CoV-2) and the resulting COVID-19 have led to significant morbidity and mortality among solid organ transplant recipients since the start of the pandemic. 1 Mutations in the viral spike protein have led to the emergence of numerous variants, with the Omicron variant and its sublineages dominating since December 2021. 2, 3 Although the rates of hospitalization and in-hospital mortality fell in the general population during the Omicron surge, the morbidity and mortality among solid organ transplant recipients remained disproportionately high. 4, 5 Vaccination is the cornerstone of prevention of severe COVID-19 in the general population; however, the immune response to vaccination among solid organ transplant recipients is often inadequate, leaving them susceptible to severe illness. A study of 658 solid organ transplant recipients, including 71 lung transplant recipients (LTRs), showed that only 39% of LTRs developed an antibody response after 2 doses of a SARS-CoV-2 mRNA vaccine. 6 Furthermore, although a third vaccine dose improved the humoral response Lung Transplantation Background. Lung transplant recipients (LTRs) have an increased risk of COVID-19-related morbidity and mortality. Tixagevimab-cilgavimab (tix-cil) is a long-acting monoclonal antibody combination granted Emergency Use Authorization approval by the US Food and Drug Administration for COVID-19 pre-exposure prophylaxis (PrEP) in immunocompromised patients. We sought to determine whether tix-cil 300-300 mg reduced the incidence and disease severity of severe acute respiratory syndrome coronavirus 2 infection in LTRs during the Omicron wave. Methods. We performed a retrospective, single-center cohort study of LTRs who had received a COVID-19 diagnosis between December 2021 and August 2022. We compared baseline characteristics and clinical outcomes after COVID-19 between LTRs who received tix-cil PrEP and those who did not. We then conducted propensity-score matching based on baseline characteristics and therapeutic interventions and compared clinical outcomes between the 2 groups. Results. Of 203 LTRs who received tix-cil PrEP and 343 who did not, 24 (11.8%) and 57 (16.6%), respectively, developed symptomatic COVID-19 (hazard ratio [HR], 0.669; 95% confidence interval [CI], 0.415-1.079; P = 0.099). The hospitalization rate of LTRs with COVID-19 during the Omicron wave trended lower in the tix-cil group than in the non-tix-cil group (20.8% versus 43.1%; HR, 0.430; 95% CI, 0.165-1.118; P = 0.083). In propensity-matched analyses, 17 LTRs who received tix-cil and 17 LTRs who did not had similar rates of hospitalization (HR, 0.468;
