Trial summary

Pleural and peritoneal mesotheliomas (PPM) are rare cancers mostly related to asbestos-exposure, which are characterized by a complex histopathological diagnosis and staging, few therapeutic options and a dismal prognosis. The main unmet medical need in PPM is the lack of a treatment sequence for affected patients. Read more about this study

About this study

Official title: From Immune Microenvironment Characterization and Gene Expression Profiling to New Drugs Testing in Pleural and Peritoneal Mesothelioma: Imaging-Meso Study

Pleural and peritoneal mesotheliomas (PPM) are rare cancers mostly related to asbestos-exposure, which are characterized by a complex histopathological diagnosis and staging, few therapeutic options and a dismal prognosis. The main unmet medical need in PPM is the lack of a treatment sequence for affected patients. The advent of immune checkpoint inhibitors has changed the first line treatment of PPM, thanks to the improvement in survival achieved by the combination of ipilimumab and nivolumab that are currently approved for non-epithelioid histology in our Country.

PPM is characterized by a large heterogeneity of the genomic landscape, which is mainly characterized by the loss of tumour suppressor genes and mutations in DNA repair genes and by an "altered- suppressed" or "excluded" tumor immune microenvironment (TIME).

The goal of this project is to improve the immune-biological and molecular stratification of PPM subgroups that can lead to the identification of different personalized treatment approaches. PPM patients (N=220) will be retrospectively (N=150) and prospectively (N=70) recruited from the coordinator center and 6 participating Italian centers. Treatment-naïve tumor samples will be collected and analyzed by bulk gene expression and spatial whole transcriptome analysis, and by 9-color multiplex immunofluorescence.

New targets or actionable pathways potentially emerging from such studies will be finally assessed and validated in patient-derived organoids/xenografts that accurately reflect PPM tumorigenesis.

  • Translation analysisOther

    Bulk GEP analysis, Spatial whole transcriptome analysis, mIF analysis of tumors

What is being measured

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

  1. Primary outcome

    PPM treatment-naïve tumor samples and classification in different clusters according to the differential expression of molecular and gene signatures by Gene expression profile (GEP) analysis.

    Measured: Through study completion, an average of 3 years

  2. Primary outcome

    Identification of molecular and immune signatures predictive of resistance or sensitivity to systemic anticancer drugs: chemotherapy or immunotherapy administered as first line treatment by spatial whole transcriptome analysis.

    Measured: Through study completion, an average of 3 years

  3. Primary outcome

    PPM surgical specimens and comparison with GEP in matched treatment-naïve tumor samples will be performed by gene expression profile analysis with GEP analysis.

    Measured: Through study completion, an average of 3 years

Secondary outcomes (2)
  1. Secondary outcome

    Characterization and quantification of immune cell distribution and their spatial relationships in treatment naïve tumor samples of PPM patients will be performed by a 9-color multiplex immunofluorescence (mIF) analysis.

    Measured: Through study completion, an average of 3 years

  2. Secondary outcome

    Immune phenotypes defined by mIF and the immune signatures identified by GEP analyses will be performed in each treatment-naïve tumor sample.

    Measured: Through study completion, an average of 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Mesothelioma and Mesotheliomas Pleural, run by Istituto Oncologico Veneto IRCCS at 10 sites in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Primary outcome (time frame: Through study completion, an average of 3 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2026.
