Brief summary

Patients with pleural mesothelioma that can not be surgically removed will receive durvalumab, in combination with standard chemotherapy of pemetrexed and cisplatin as first-line treatment. Durvalumab is a type of drug called a monoclonal antibody (a type of protein). Laboratory tests show that it works by allowing the immune system to detect your cancer and reactivates the immune response. This may help to slow down the growth of cancer or may cause cancer cells to die. The purpose of this study is to see whether adding durvalumab to standard chemotherapy will improve overall survival (OS).

Detailed description

Mesothelioma is a malignant tumor of the mesothelial surfaces primarily arising in the thoracic pleura and is estimated to cause 43,000 deaths worldwide each year with over 3300 cases occurring annually in the United States. Approximately 80% of cases of mesothelioma are due to inflammation induced by prior asbestos exposure with a lead time from exposure to development of cancer of 20-30 years. This is a single arm, open label phase II study of the anti-PD-L1 antibody, durvalumab, in combination with standard chemotherapy. Pemetrexed and cisplatin will be given for up to six 3-week cycles with the addition of concurrent durvalumab dosed every 3 weeks. The first 6 patients who are enrolled and commence treatment will be monitored for safety of the combination. Use of carboplatin in place of cisplatin will be permitted for patients who are ineligible for cisplatin due to impaired renal function at screening, however these patients must otherwise fulfill the eligibility criteria for the study. For patients that receive cisplatin, carboplatin may also be substituted after Cycle 1 for cisplatin related toxicity (e.g., grade 3 ototoxicity, grade 3 nausea) at the investigator's discretion. After completion of Cycle 6 of concurrent therapy, patients with stable or responding disease per modified RECIST for malignant mesothelioma will continue on single agent durvalumab every 3 weeks until progression. Maximum duration of durvalumab treatment is 12 months starting from Cycle 1 of concurrent treatment (inclusive of any treatment delays or missed treatments). Tumor assessments will be performed approximately every 6 weeks during concurrent therapy and every 9 weeks during the maintenance phase. Mandatory pre-treatment tumor tissue sample (i.e., obtained during a previous procedure or biopsy) and blood samples (prior to Cycle 1, Cycle 2 and Cycle 5) for research will also be required.

Interventions

DRUGDurvalumab

On Day 1 of each 21 day cycle: Durvalumab 1120 mg IV will be administered before pemetrexed and cisplatin chemotherapy over approximately 60 minutes. Approximately 30 minutes after the durvalumab infusion is complete, pemetrexed 500 mg/m² IV will be administered over 10 minutes. Cisplatin 75 mg/m² IV over 2 hours will begin approximately 30 minutes after the end of pemetrexed administration. If carboplatin is substituted for cisplatin, carboplatin Area Under the Concentration-Time Curve (AUC) 5 will be infused over 30 minutes beginning approximately 15-30 minutes after the end of the pemetrexed administration. Maintenance: On Day 1 of each 21 day cycle: Durvalumab 1120 mg IV over approximately 60 minutes.

Inclusion criteria

Criteria: * Histologically and/or cytologically confirmed malignant pleural mesothelioma. * Unresectable disease (defined as the participant not being a candidate for curative surgery). * Measurable disease, defined as at least 1 lesion (measurable) that can be accurately assessed at baseline by computed tomography (CT) or magnetic resonance imaging (MRI) and is suitable for repeated assessment (modified RECIST for pleural mesothelioma). * Available unstained archived tumor tissue sample in sufficient quantity to allow for analyses. At least fifteen unstained slides or a tumor block (preferred). NOTE: A fine needle aspiration sample is not sufficient to make the patient eligible for enrollment. Given the complexity of mesothelioma pathological diagnosis and that these will be newly diagnosed patients it is expected that they will have a core needle biopsy or surgical tumor biopsy as part of their initial diagnostic work up. * Age ≥ 18 years. * Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. * Ability to understand and willingness to sign Institutional Review Board (IRB)-approved informed consent. * Willing to provide archived tumor tissue and blood samples for research. * Adequate organ function as measured by the following criteria, obtained ≤ 2 weeks prior to registration: * Absolute Neutrophil Count (ANC) ≥ 1500/mm³ * Hemoglobin ˃9.0 g/dL * Platelets ˃100,000/mm³ * Serum creatinine clearance (CL)\>60 mL/min by the Cockcroft-Gault formula or by 24-hour urine collection for determination of creatinine clearance. NOTE: Patients with a creatinine Cl ≥ 45 mL/min however ≤ 60 mL/min may be considered for enrollment provided they fulfill all other eligibility criteria, these subjects will receive pemetrexed carboplatin concurrent with durvalumab during the combination phase of treatment. Patients with a creatinine CL\<45 mL/min should not be enrolled. * Albumin ≥ 2.8 g/dL * Total Bilirubin ≤ 1.5x Upper Limit of Normal (ULN) * Aspartate Aminotransferase (AST)/Alanine Aminotransferase (ALT) ≤ 2.5x ULN (≤ 5x ULN in patients with liver metastases) * Women must either be of non-reproductive potential or must have a negative serum pregnancy test upon study entry. * Women must not be pregnant or breastfeeding. * Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow-up. * Patient must not have involvement in the planning and/or conduct of the study. No previous enrollment in the present study. * Patients may not have participated in another clinical study with an investigational product during the last 4 weeks. * Patients must not have any prior systemic therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, and other investigational agent) for mesothelioma. * No previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab or any other agent targeting immune checkpoints. * Patients must not have non-pleural mesothelioma e.g. mesothelioma arising in peritoneum, tunica vaginalis or any serosal surface other than the pleura. * Patients must not have an active second malignancy other than non-melanoma skin cancer or cervical carcinoma in situ. * Patients must not have mean QT interval corrected for heart rate (QTc) ≥470 ms calculated from 3 electrocardiograms (ECGs) using Frediricia's Correction. * Patients must not have symptomatic or uncontrolled brain metastases requiring concurrent treatment, inclusive of but not limited to surgery, radiation and/or corticosteroids (prednisone \>10 mg or equivalent). Surgery, radiation and/or corticosteroids (any dose \>10 mg prednisone equivalent) must have been completed ≥ 2 weeks prior to registration. * Patients must not have uncontrolled seizures. * Patients must not have current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. Standard steroid premedication given prior to chemotherapy or as prophylaxis for imaging contrast allergy should not be counted for this criterion. * No active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease, diverticulitis with the exception of diverticulosis, celiac disease, irritable bowel disease; Wegner syndrome) within the past 2 years. Subjects with vitiligo, alopecia, Grave's disease, or psoriasis not requiring systemic treatment (within the past 3 years) are not excluded. * No history of primary immunodeficiency. * No history of allogeneic organ transplant. * No history of hypersensitivity to durvalumab, cisplatin, carboplatin, pemetrexed or any of their excipients. * No uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, active bleeding diatheses including any subject known to have psychiatric illness/social situations that would limit compliance with study requirements or compromise the ability of the subject to give written informed consent. * No active infection including tuberculosis (clinical evaluation including: physical examination findings, radiographic findings, positive PPD test, etc.), hepatitis B (known positive HBV surface antigen \[HBsAg\] result), hepatitis C, or human immunodeficiency virus (positive HIV 1/2 antibodies as defined by a positive ELISA test).
