Phase II MEDI4736 in Combination With Chemotherapy for First-Line Treatment of Unresectable Mesothelioma (PrE0505)

Open Label, Phase II Study of Anti - Programmed Death - Ligand 1 Antibody, Durvalumab (MEDI4736), in Combination With Chemotherapy for the First-Line Treatment of Unresectable Mesothelioma

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).

Study Overview

• Status: Completed
• Conditions: Mesothelioma; Pleural Mesothelioma
• Intervention / Treatment: Drug: Durvalumab

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.

Intervention / Treatment

Experimental: Durvalumab; Pemetrexed/cisplatin will be given for up to six 3-week cycles with the addition of concurrent durvalumab 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. 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).

Drug: Durvalumab; 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.; Other Names: MEDI4736
