ECMM Candida IV
Antifungal tolerance, resistance and clinical outcomes on candidemia caused by non-albicans Candida
Observation periods/Timeline
Observation period: April 1st, 2024 – September 30th, 2025
Database closure December 31st 2025
First manuscript with main outcomes submitted for publication March 31st, 2026
The ECMM (European Confederation of Medical Mycology) conducts international studies on invasive candidiasis (IC) at regular 5- to 10-year intervals. In continuation of this tradition, the fourth multicenter ECMM study was started in April 2024, focusing on candidemia caused by non-albicans Candida species. The aim is to investigate antifungal resistance and tolerance, and their association with clinical outcomes in institutions across the globe. The study is titled:
“Antifungal tolerance, resistance and clinical outcomes in candidemia caused by non-albicans Candida.” It was developed by ECMM President Prof. Martin Hoenigl (Principal Investigator) in collaboration with immediate past ECMM President Prof. Oliver Cornely (Co-Principal Investigator). The study also evaluates the activity of novel antifungals in late-stage clinical development to assess whether they can overcome the challenges posed by these pathogens. With a strong translational focus, the project links clinical data and patient outcomes with findings from basic mycology laboratories, particularly regarding the impact of antifungal tolerance on a large scale.
The observation period runs from April 1st, 2024 to September 30th, 2025. Data on the clinical course, treatment, and outcomes will be entered into the ECMM Candida IV EDC System (Carelane). The database will close three months after the end of the observation period. All data entries must be completed in the electronic case report form (eCRF) by December 31st, 2025.
Eligible are adult patients with candidemia due to non-albicans Candida species, defined according to ECMM/ESCMID criteria (i.e. at least one positive blood culture) (1, 2). Participating centers are expected to include all cases occurring between April 1st, 2024 and September 30th, 2025. Patients will be excluded if the fungal isolate responsible for the candidemia is no longer available.
Participation involves the submission of:
- Clinical and microbiological data for the eCRF
- Isolates of non-albicans Candida spp. (not required for Candida auris)
- All isolates should be stored locally and shipped in a single batch at the end of the study. A case-based reimbursement of 100 EUR per isolate and completed eCRF will be provided.
Candida isolates of cases are collected by the ECMM in central repositories under supervision of:
- Maiken Arendrup (maca@ssi.dk) /Conny Lass-Floerl (cornelia.lass-floerl@i-med.ac.at) for isolates collected from participating institutions in Europe
- Sevtap Arikan-Akdagli (sarikanakdagli@gmail.com) for isolates collected from participating institutions in Turkey
- Anuradha Chowdhary (chowdhary.anuradha@gmail.com) for isolates collected from participating institutions in Asia
- Wenjie Fang (fangwenjie1990@126.com; Shanghai Key Laboratory of Molecular Medical Mycology Shanghai Changzheng Hospital) for isolates collected from participating institutions in China
- Sharon Chen (Sharon.Chen@health.nsw.gov.au) for isolates collected from participating institutions in Australia/Oceania
- Gustavo Goldman (ggoldman@usp.br)/Arnaldo Colombo (arnaldolcolombo@gmail.com.br) for isolates collected from participating institutions in Latin America
- Rita Oladele (roladele@unilag.edu.ng) for isolates collected from participating institutions in Africa
- Peter Pappas (ppappas@uabmc.edu) for isolates collected from participating institutions in North American participants
