Ipilimumab and Nivolumab in the Treatment of Malignant Pleural Mesothelioma

• Status: Completed
• Trial end date: 2019-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a prospective, monocenter, single arm, phase II trial in 33 patients with unresectable MPM, who experience disease progression or recurrence after at least one previous line of platinum-based systemic treatment.

Nivolumab will be administered at a fixed dose of 240 mg every 2 week. Nivolumab will be given in combination with ipilimumab on week 1, 7, 13 and 19 and will be administered prior to the infusion of ipilimumab. Ipilimumab will be administered at the dose of 1 mg/Kg.The patients will receive nivolumab monotherapy on week 3, 5, 9, 11, 15 and 17. From week 21 thereafter, Nivolumab will be then administered every 2 weeks for a maximum period of 2 years or until disease progression or unacceptable toxicity occurs.

Exclusion Criteria:

• Medical or psychological impediment to comply with the protocol

• Patients with only peritoneal MPM

• Previous treatment with any checkpoint inhibitor

• Pregnant or lactating women

• Patients with brain metastases

• History of or active autoimmune disease (e.g. pneumonitis; rheumatoid arthritis; severe form of psoriasis; uncontrolled type I diabetes or hypothyroidism)

• History of idiopathic pulmonary fibrosis (including pneumonitis) or unresolved drug-induced pneumonitis, organizing pneumonia, or active pneumonitis on screening chest CT scan

• History of relevant gastrointestinal disease, including, but not limited to, Crohn's disease, ulcerative colitis, recurrent diverticulitis

• Prior allogenic bone marrow transplantation or prior solid organ transplantation

• History of HIV

• Patients with history of HBV infection are eligible if serological profile is compatible with past/resolved infection (defined as negative HBsAg test and positive antibody to HBV core antigen [anti-HBc] antibody test) and HBsAg test and HBV-DNA are both negative prior to Cycle 1, Day 1

• Patients with history of HCV infection must be screened for HCV-RNA PCR test prior to Cycle 1, Day 1, and are eligible if the test turns negative

• Other serious concomitant disease, including:

Active tuberculosis Severe infections within 4 weeks prior to Cycle 1, Day 1 Significant cardiovascular disease (NYHA class III or IV), myocardial infarction within the previous 6 months, unstable angina, or unstable arrhythmias Significant pulmonary (asthma or COPD) or hepatic disease or other illness considered by the investigator to constitute an unwarranted high risk for investigational treatment
