About this study

Official title: Beyond Eosinophils: Proteomics to Identify Potential Biomarkers of Organ Damage and Response to MEPOLIZUMAB in EGPA

Aim of the study is to identify potential biomarkers, through a proteomic approach, which could be used to evaluate organ damage and predict the response to mepolizumab in a cohort of patients affected by EGPA. Proteomic analyses will be performed using a proteomic platform, based on a nano-HPLC- couplet to an high resolution ESI-MS device, on three types of biological matrices: blood, saliva and sputum samples in both EGPA and severe asthmatic patients (as controls) at baseline and at different time points after starting treatment with mepolizumab, an anti-IL-5 drug, in order to cluster patients and to analyze the effect of the therapy during treatment, assessing the disease progression on three key aspects: lung function and symptoms control, vasculitis and neuropathy. Plasma analysis will provide an overview of quantitative/qualitative proteomic variations at systemic level after drug administration; however, a less invasive procedure is often sufficient and would improve trial recruitment. On this regard, saliva is a biological fluid well suitable to be used in proteomic investigations for suggestion of potential disease biomarkers and includes various potential advantages compared with blood sample collection such as lower overall cost, lower infection risk, increased patient convenience, acceptability, compliance and uptake. Moreover, the protein composition of the human saliva includes both specific proteins of the oral cavity and proteins common to other tissues and bodily fluids, so saliva prognostic and diagnostic role is particularly interesting. Consequently, the plan is to compare the proteomic results of the non-invasive saliva testing to that of blood examination.

These data may be a further step to untangle the mechanisms of the disease and to characterize treatment's response, in the contest of a phenotype/endotype asthma management.

What is being measured

The primary outcome is the main question the study is designed to answer.

    Measured: From the data to the enrollment until the end of the study, up to 52 weeks.

Secondary outcomes (1)
  1. If it is possible to predict the response to treatment by analyzing the proteomic profile of the patients.

    untangle the mechanisms of the disease and to characterize response to treatment, in the context of a phenotype/endotype asthma and EGPA management

    Measured: From date of randomization until the date of first documented progression, assessed up to 24 months

Model description
According to the patients' groups evaluated in other publications with a robust statistical method and sample size calculation performed by the team, a sample of 90 patients can be considered sufficient to allow the realization of the study. The investigators plan to enroll 90 patients followed in Allergy and Clinical Immunology Centers divided into three groups: * 30 patients with EGPA with predominant ENT/asthmatic phenotype (longitudinal sampling before and after Mepolizumab treatment) * 30 patients with EGPA with vasculitic phenotype before and after immunosuppressive drugs (CYC, AZA, MTX) and/or Mepolizumab. * 30 patients with a diagnosis of severe eosinophilic asthma (longitudinal sampling before and after Mepolizumab treatment)

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Saliva, sputum, and plasma proteomic profile of EGPA patients (time frame: From the data to the enrollment until the end of the study, up to 52 weeks.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07343661, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
