Detailed Description
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Primary endpoint - To evaluate the activity of neo-adjuvant treatment by the determination of pathological complete response rate (pCR)
Time Frame: Pathological complete response will be evaluated following neoadjuvant treatment and within 6 weeks after the last dose of study intervention.
|
Pathological complete response defined as 0% residual viable tumor cells in the primary tumor and in sampled lymph nodes, following neoadjuvant treatment as assessed by central pathology assessment.
Patients who are not evaluable per central pathology assessment (this includes patients with R2 margins) or who do not have a surgical specimen will be considered as non-pCR (eg, pathology assessments captured as "non-evaluable" or "missing," as appropriate).
Patients who received less than 2 cycles out of the planned 3 cycles of neoadjuvant therapy due to unacceptable toxicity will not be considered in the pCR evaluation.
|
Pathological complete response will be evaluated following neoadjuvant treatment and within 6 weeks after the last dose of study intervention.
|
