Use of isavuconazole in critically ill patients in intensive care units: a prospective, observational, multicentre, cohort study

Abstract

Objectives: In this multicentre, prospective study, we aimed to describe the use of isavuconazole in critically ill adult patients in ICU, in terms of patient characteristics, infection characteristics and outcomes.

Methods: Prospective, observational study of ICU patients treated with isavuconazole from January 2023 to 30 April 2025 in 17 centres (ISA-SITA study within the MULTI-SITA project).

Results: A total of 177 ICU patients treated with isavuconazole were included in the study. Most patients showed at least one European Organisation for Research and Treatment of Cancer/Mycoses Study Group Education and Research Consortium (EORTC/MSGERC) or FUNgal Diseases in adult patients in Intensive Care Unit (FUNDICU) host factor (141/177, 79.7%). Overall, 82/177 patients (46.3%) had either proven or probable invasive mould disease (6 and 76, respectively, mostly invasive pulmonary aspergillosis). In patients with proven or probable disease, 30-day mortality was 44.0%, and 90-day mortality was 62.2%. In multivariable analyses, SOFA score (HR 1.14 per one point increase, 95% CI 1.03-1.26, P = 0.010) and concomitant bacterial pneumonia (HR 2.32, 95% CI 1.17-4.59, P = 0.016) were associated with 30-day mortality, whereas prior hospitalization (HR 2.26, 95% CI 1.19-4.27, P = 0.013) and SOFA score (HR 1.17 per one point increase, 95% CI 1.07-1.28, P < 0.001) were associated with 90-day mortality.

Conclusions: Diverse patterns of isavuconazole use were observed in a large cohort of critically ill adult patients, and the drug was well tolerated. Mortality was lower than many previous estimates in critically ill patients and could serve as a basis for future standardized comparisons.

Cumulative mortality up to Day 30 in critically ill patients with proven and probable invasive aspergillosis/mucormycosis treated with isavuconazole. (a) Cumulative mortality up to Day 30 in ICU patients with proven or probable invasive mould disease treated with isavuconazole. (b) Cumulative mortality up to Day 30 in ICU patients with probable invasive mould disease treated with isavuconazole, stratified for classification as probable according to EORTC/MSGERC versus FUNDICU definitions. For both panels, the time of origin was set at the day of isavuconazole initiation. Death was the event of interest and right-censoring was applied at the end of follow-up (loss to follow-up before Day 30, e.g. for hospital discharge, or Day 30, whichever came first). For further details, see Materials and methods. EORTC, European Organisation for Research and Treatment of Cancer; FUNDICU, invasive FUNgal Diseases in adult patients in Intensive Care Unit; MSGERC, Mycoses Study Group Education and Research Consortium.
