Preventing Severe COVID-19 with Tixagevimab-Cilgavimab in Hematological Patients Treated with Anti-CD20 Monoclonal Antibodies: An International Multicenter Study.
Article in Infectious diseases and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDespite the declining public health emergency status, COVID-19 still poses significant risks, especially for immunocompromised individuals. We aimed to evaluate the effectiveness of tixagevimab-cilgavimab (T-C) prophylaxis in preventing severe COVID-19 in patients with hematologic malignancies (HM) treated with anti-CD20 therapy during the early Omicron variant phase of the pandemic.
methodsThe European Society of Clinical Microbiology and Infectious Diseases Study Group for Respiratory Viruses (ESGREV) conducted a multicenter retrospective cohort study involving 15 centers from 5 countries. The study included 749 patients with HM treated with anti-CD20 between February 15 and June 30, 2022, comparing 215 who received T-C prophylaxis to 534 who did not.
resultsThe study revealed a significant reduction in the risk of COVID-19 among patients who received T-C prophylaxis compared to those who did not (11.2% vs 23.4%, p < 0.001), with hazard ratio (HR) of 0.40 (95% CI 0.26-0.63), adjusted for age, sex, vaccination status, baseline HM malignancy and type of anti-CD-20. We also demonstrated a reduction for severe-critical diseases within all study populations, 1.4% vs 5.2%, p = 0.017, HR 0.26 (95% CI 0.08-0.84).
conclusionT-C prophylaxis effectively prevented COVID-19 and severe-critical COVID-19 in patients with HM treated with anti-CD20 monoclonal antibodies during the early Omicron variant phase of the pandemic. Even though T-C is ineffective against current variants, these findings highlight the importance of additional protective measures and the continued development of monoclonal antibodies to protect immunocompromised individuals to mitigate the impact of COVID-19 and other respiratory viral diseases.
