* Has received prior radiotherapy within 2 weeks of start of study intervention or radiation-related toxicities requiring corticosteroids. Note: Two weeks or fewer of palliative radiotherapy for non-CNS disease is permitted.

* Has received an investigational agent or has used an investigational device within 4 weeks prior to study intervention administration.
* Known additional malignancy that is progressing or has required active treatment within the past 5 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin or adequately treated carcinoma in-situ without evidence of disease are not excluded. Participants with low-risk early-stage prostate cancer (T1-T2a, Gleason score ≤6, and PSA \<10 ng/mL) either treated with definitive intent or untreated in active surveillance with stable disease are not excluded.
* Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
* Has active autoimmune disease that has required systemic treatment in the past 2 years except replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid).
* History of Hepatitis B (defined as HbsAg reactive) or known active Hepatitis C virus (defined as detectable HCV RNA \[qualitative\]) infection.
* Has not adequately recovered from major surgery or has ongoing surgical complications.
* Has a history or current evidence of any condition, therapy, or laboratory abnormality or other circumstance that might confound the results of the study, interfere with the participant's participation for the full duration of the study, such that it is not in the best interest of the participant to participate, in the opinion of the treating investigator.
* Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
* Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment.
* Has had an allogenic tissue/solid organ transplant.
* History of HIV infection. HIV testing is not required unless mandated by local health authority.

Single arm Carboplatin/Cisplatin - Pemetrexed - Pembrolizumab
The neoadjuvant systemic treatment will be based on three cycles of pembrolizumab 200 mg flat dose in combination with standard doses of cisplatin (75 mg/sm) or carboplatin (AUC 5) and pemetrexed (500 mg/sm) administered intra-venous every 3 weeks.
The surgical intervention of pleurectomy/decortication will be planned to occur within 6 weeks after the completion of neoadjuvant treatment.
The adjuvant systemic treatment will be based on 14 cycles of pembrolizumab 200 mg flat dose administered intra-venous every 3 weeks. Patients should be able to start pembrolizumab following surgery as soon as clinically feasible and within 10 weeks from surgery.

Résumé de l'étude
This is a prospective, open-label, multi-site Phase II trial of pembrolizumab in combination with pemetrexed and cisplatin or carboplatin as neo-adjuvant therapy followed by surgery and adjuvant pembrolizumab in patients affected by resectable stage I-IIIa chemonaïve epithelioid/biphasic pleural mesothelioma.

This is a prospective, open-label, multi-site Phase II trial of pembrolizumab in combination with pemetrexed and cisplatin or carboplatin as neo-adjuvant therapy followed by surgery and adjuvant pembrolizumab in patients affected by resectable stage I-IIIa chemonaïve epithelioid/biphasic pleural mesothelioma.
The neoadjuvant systemic treatment will be based on three cycles of pembrolizumab 200 mg flat dose in combination with standard doses of cisplatin (75 mg/sm) or carboplatin (AUC 5) and pemetrexed (500 mg/sm) administered intra-venous every 3 weeks.
The surgical intervention of pleurectomy/decortication will be planned to occur within 6 weeks after the completion of neoadjuvant treatment.
The adjuvant systemic treatment will be based on 14 cycles of pembrolizumab 200 mg flat dose administered intra-venous every 3 weeks. Patients should be able to start pembrolizumab following surgery as soon as clinically feasible and within 10 weeks from surgery.
All participating centers will enroll eligible patients and administer neoadjuvant and adjuvant systemic treatment.
Thoracic surgery will be centralized in two reference centres (AOUPD PADOVA AND HUMANITAS CANCER CENTER).
All eligible patients will undergo two multidisciplinary team discussions, before and after induction systemic treatment.
The primary objective of this trial is to determine the pathological complete response rate of pembrolizumab in combination with standard doses of cisplatin or carboplatin and pemetrexed administered intra-venous every 3 weeks for three cycles. Pathological response will be centrally assessed by a blinded pathologist.
Radiological and metabolic assessment through CT-scan and PET-CT will be performed at the baseline and at the end of neoadjuvant chemo-immunotherapy. Radiological CT-scan will be then performed every 9 weeks (+/- 1 week) during the adjuvant treatment. Further radiological follow-up after the end of study treatment (or for those patients with early treatment discontinuation without disease relapse) will be performed every 12 weeks until a two-year period from surgery, followed by every 18 weeks until the fifth year.
Radiological response will be centrally assessed by a blinded radiologist. Adverse events will be monitored throughout the trial and graded in severity according to the guidelines outlined in the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
