Abstract
Objective: Tixagevimab/cilgavimab is a cocktail of two long-acting monoclonal antibodies approved for pre-exposure prophylaxis (PrEP) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection (cause of coronavirus disease 2019 [COVID-19]) in immunocompromised (IC) or high-risk patients. We investigated the patient characteristics and clinical outcomes of IC patients administered tixagevimab/cilgavimab for PrEP in real-world use in Japan.
Methods: This observational study used anonymous secondary data from Real-World Data Co., Ltd. for IC patients aged ≥12 years administered tixagevimab/cilgavimab between September 2022 and September 2023. We analyzed the baseline characteristics and event-rates of COVID-19-related clinical outcomes within 6 months of administration.
Results: Data were analyzed for 397 IC patients. About half (53.4 %) were male and the median age was 71.0 (interquartile range 61.0, 77.0) years. Malignancy (97.2 %), cardiovascular disease (71.3 %), and diabetes (66.5 %) were frequent comorbidities. Systemic corticosteroids and immunosuppressants were prescribed to 87.4 % and 24.9 %, respectively. The two most common target clinical conditions were active therapy for hematologic malignancies (88.2 %) and treatment with B cell-depleting therapies (57.4 %). The event-rates per 100 person-months (95 % confidence interval; number) for medically attended COVID-19, COVID-19 hospitalization, in-hospital mortality due to COVID-19, and all-cause death were 4.14 (3.06-5.48; n = 49), 1.74 (1.09-2.64; n = 22), 0.07 (0.00-0.42; n = 1), and 0.60 (0.26-1.17; n = 8), respectively.
Conclusion: This is the first report using a multicenter database to describe the clinical characteristics and COVID-19-related outcomes of IC patients administered with tixagevimab/cilgavimab in real-world settings in Japan. This cohort of IC patients who received tixagevimab/cilgavimab included many elderly patients with comorbidities.
期刊介绍:
The Journal of Infection and Chemotherapy (JIC) — official journal of the Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases — welcomes original papers, laboratory or clinical, as well as case reports, notes, committee reports, surveillance and guidelines from all parts of the world on all aspects of chemotherapy, covering the pathogenesis, diagnosis, treatment, and control of infection, including treatment with anticancer drugs. Experimental studies on animal models and pharmacokinetics, and reports on epidemiology and clinical trials are particularly welcome.
