SARS-COV-2 Pre-Exposure Prophylaxis With Tixagevimab-Cilgavimab in Haematological, Immunocompromised Patients in the Omicron Era.
Article in European journal of haematology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPre-exposure prophylaxis with tixagevimab-cilgavimab significantly reduced severe COVID-19 outcomes in high-risk individuals during the pre-Omicron era (PROVENT trial). However, efficacy in patients with haematological malignancies (HM) was underreported. The rapid emergence of Omicron strains in 2021 showed reduced neutralizing activity in preclinical data, but real-world data remains limited due to short follow-up. PATIENTS AND
methodsWe aimed to evaluate the effectiveness and safety of tixagevimab-cilgavimab in 86 HM patients during the early Omicron wave, including the BA.2, BA.5, and XBB.1 sublineages. These patients received PrEP between February and August 2022 due to impaired vaccine response (72%) and B-cell depletion (46.5%). They were followed prospectively until April 2023, with a median follow-up of 297 days.
resultsBreakthrough SARS-CoV-2 infections occurred in 32.6% of patients, with 22.1% within six months. Infections within six months were milder and shorter. B-cell depletion within six (p = 0.035) and twelve months (p = 0.016) was identified as risk factor for breakthrough infections. No new safety events were reported.
conclusionOur data showed that tixagevimab-cilgavimab prophylaxis effectively reduces severe COVID-19 outcomes in patients with HM, particularly within the first six months, even during the Omicron era. However, those with recent B-cell depletion (within 12 months) remained at high risk.
