Study summary

Meso-Immune is a retrospective study to assess the efficacy and safety of the combination of Nivolumab and Ipilimumab used in first-line treatment of adult patients with unresectable Malignant Pleural Mesothelioma (MPM). This combination of treatments has been approved in Europe since June 2021 based on the results of the CheckMate 743 study. In France, the combination is not yet reimbursed for this population of patients. However, since April 01, 2021, newly diagnosed unresectable MPM patients may be treated with this combination via an early access program.

Meso-Immune study targets these patients included in the early access program with the objective to provide additional results to the CheckMate 743 study and confirm the benefit of using this combination in first-line of treatment in this category of patients.

Total study duration will cover 48 months with an inclusion period of 12 months and a follow-up until 3 years. Patients will be recruited retrospectively starting April 01, 2021 until April 01, 2022.

Meso-Immune study will be proposed to all the GFPC centers that have already included patients in the early access program and other centers wishing to participate, in order to analyze a minimum of 150 patients. The total number of sites is evaluated at around 120.

The principal investigator in each center will identify the patients eligible for the Meso-Immune study and will inform them on the study according to the local regulations.

Patient follow-up will be pursued regularly, in in-patient and out-patient clinics, according to the usual practices of the physicians in each participating center. Reevaluation workups will be pursued according to the practices of each center.

The information related to Patient characteristics, MPM characteristics, Treatment characteristics, Disease progression, Rebiopsy, Post treatments, Adverse events, Date and cause of death, Date of last news will be recorded in electronic case-report forms (eCRF).

Qualitative variables will be presented descriptively in the principal analysis.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
