Observational Study in Patients With Previously Unresectable Malignant Pleural Mesothelioma Treated With Nivolumab and Ipilimumab (MESO-IMMUNE)

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.

Treatment and study plan

Data Collection

Other

Observational study without intervention except retrospective and prospective data collection : Patient characteristics, MPM characteristics, Treatment characteristics, Disease progression, Rebiopsy, Post treatments, Adverse events, Date and cause of death, Date of last news ; recorded in electronic case-report forms (eCRF).

Primary outcomes

  1. Progression Free Survival assessed locally

    Time frame: time from first dose of combination Nivolumab-Ipilimumab to first documentation of disease progression or to death from any cause evaluated through the total duration of the study (up to 48 months)

    Progression free survival as assessed by the investigator, defined as the time from first dose of combination Nivolumab-Ipilimumab to first documentation of disease progression or to death from any cause, whichever came first

Secondary outcomes

  1. Potential professional exposure(s)

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes. Qualitative parameters will be expressed as numbers, percentages and 95% confidence intervals.

  2. Eastern Cooperative Oncology Group performance status (PS)

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes. Quantitative parameters will be expressed as means, standard deviations or medians and interquartile ranges.

  3. Body weight

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes expressed in kilograms. Quantitative parameters will be expressed as means, standard deviations or medians and interquartile ranges.

  4. Body mass index (BMI)

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms and height in metres. Quantitative parameters will be expressed as means, standard deviations or medians and interquartile ranges.

  5. Smoking status

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes. Qualitative parameters will be expressed as numbers, percentages and 95% confidence intervals.

  6. Medical history

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes. Qualitative parameters will be expressed as numbers, percentages and 95% confidence intervals.

  7. Comorbidities

    Time frame: At Baseline

    Unresectable Malignant Pleural Mesothelioma Patients' characteristics based on data collected from the patient medical notes. Qualitative parameters will be expressed as numbers, percentages and 95% confidence intervals.

  8. Past history of cancer or auto-immune disease
