Sponsored by Centre Hospitalier Universitaire Vaudois · Observational
The FIND-VEXAS project is a multicenter, cross-sectional observational study conducted in Internal Medicine departments in the Friuli Venezia Giulia region of Italy.
The study aims to estimate how frequently VEXAS syndrome occurs among adults older than 50 years who are admitted to Internal Medicine units with otherwise unexplained systemic inflammation or hematologic abnormalities, such as fever, elevated inflammatory markers, macrocytic anemia, thrombocytopenia, or other cytopenias.
Participants will be assessed using clinical information, physical examination findings, routine laboratory tests, and imaging data. Patients with findings suggestive of VEXAS syndrome will be selected for confirmatory genetic testing of the UBA1 gene using blood or bone marrow samples.
In addition to estimating the prevalence of genetically confirmed VEXAS syndrome, the study will describe the clinical manifestations, hematologic abnormalities, inflammatory profile, and organ involvement of patients with suspected or confirmed disease.
VEXAS syndrome is an adult-onset autoinflammatory disease caused by acquired somatic mutations in the UBA1 gene. The condition is characterized by systemic inflammation, cytopenias, and multiorgan involvement, which may affect the skin, lungs, joints, cartilage, and blood vessels. VEXAS syndrome may also overlap with hematologic disorders, including myelodysplastic syndromes.
The disorder mainly affects men older than 50 years, a population frequently admitted to Internal Medicine departments. Patients with VEXAS syndrome may initially present with nonspecific findings such as unexplained fever, persistently elevated C-reactive protein or erythrocyte sedimentation rate, macrocytic anemia, thrombocytopenia, other cytopenias, or systemic inflammation without an identifiable infectious, neoplastic, or other clear cause.
The FIND-VEXAS project is a multicenter, cross-sectional observational study involving Internal Medicine departments affiliated with the FADOI Friuli Venezia Giulia network. The planned study duration is 24 months. Eligible participants will be adults older than 50 years who are admitted with unexplained inflammatory and hematologic abnormalities.
Participating centers will use routinely available clinical, laboratory, and imaging information to identify patients with features suggestive of VEXAS syndrome. The assessment may include medical history, physical examination, standard blood tests, and radiological examinations performed as part of routine clinical care. A structured screening pathway will be used to support diagnostic suspicion and identify patients who should undergo molecular confirmation.
Blood or bone marrow samples from patients with suspected VEXAS syndrome will be sent to the Immunology Laboratory at IRCCS Burlo Garofolo in Trieste, which will act as the regional reference center for UBA1 sequencing. Suspected cases identified across participating Internal Medicine departments will therefore be centralized for genetic confirmation.
The primary objective is to estimate the prevalence of genetically confirmed VEXAS syndrome in the Internal Medicine setting. Additional objectives are to describe the clinical presentation, hematologic features, inflammatory profile, and patterns of organ involvement among patients with suspected or genetically confirmed VEXAS syndrome.
The study is expected to improve recognition of VEXAS syndrome through clinically applicable screening criteria and to strengthen collaboration between Internal Medicine departments and specialized Immunology and Hematology laboratories.
Centre Hospitalier Universitaire Vaudois is the lead sponsor of 208 studies on the registry; 48 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Adults older than 50 years admitted to participating Internal Medicine departments of the FADOI Friuli Venezia Giulia network with otherwise unexplained systemic inflammation and/or hematologic abnormalities, including fever, elevated inflammatory markers, macrocytic anemia, thrombocytopenia, other cytopenias, or systemic inflammatory manifestations without a clear etiology. Clinical, laboratory, and imaging data routinely available during hospital care will be used to identify participants with features suggestive of VEXAS syndrome. Selected suspected cases will undergo confirmatory UBA1 genetic testing.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Adults older than 50 years admitted to participating Internal Medicine departments with otherwise unexplained systemic inflammation and hematologic abnormalities, including fever, elevated inflammatory markers, macrocytic anemia, thrombocytopenia, or other cytopenias. Participants will be assessed using routinely available clinical, laboratory, and imaging data. Patients meeting the predefined criteria for suspected VEXAS syndrome will undergo molecular testing for UBA1 mutations
Diagnostic Test: UBA1 Genetic Testing
Blood or bone marrow samples from participants with clinical features suggestive of VEXAS syndrome will be analyzed for somatic mutations in the UBA1 gene. Molecular testing will be performed centrally at the Immunology Laboratory of IRCCS Burlo Garofolo in Trieste.
Also known as: Molecular confirmation of VEXAS syndrome
Prevalence of Genetically Confirmed VEXAS Syndrome
Proportion of enrolled participants with a somatic pathogenic mutation in the UBA1 gene confirming the diagnosis of VEXAS syndrome. Prevalence will be calculated as the number of genetically confirmed VEXAS cases divided by the total number of participants included in the study and evaluated according to the study screening pathway.
