  Purpose
This is a Phase 2b, randomized, double-blind, parallel-group study. Subjects with unresectable pleural or peritoneal malignant mesothelioma will be randomized in a 2:1 ratio to receive either tremelimumab or placebo. Approximately 564 subjects will be enrolled at study centers in multiple countries. The study consists of a screening period, a treatment period, a 90-day follow-up period for safety, and a long-term survival follow-up period.

Primary Outcome Measures:
  • Overall Survival (OS) [ Time Frame: 3 years. ]
    Overall survival (OS) by treatment arm


Secondary Outcome Measures:
  • OS Rate at 18 Months by Treatment Arm [ Time Frame: 18 months ]
    The percentage of patients still alive at 18 months

  • Progression-free Survival by Treatment Arm [ Time Frame: Time from randomization to disease progression or death, whichever occurs first, assessed up to 3 years. ]
    Progression-free survival will be measured from randomization to the first documentation of disease progression or death due to any cause, whichever occurs first. Progression is defined using the modified Response Evaluation Criteria in Solid Tumours (RECIST) for pleural mesothelioma or RECIST v1.1 for peritoneal mesothelioma and assessed by computed tomography (CT) or magnetic resonance imaging (MRI), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

  • Overall Response Rate by Treatment Arm [ Time Frame: Time from randomization to best response to treatment, assessed up to 3 years. ]
    Overall response rate is defined as the proportion of participants with confirmed CR or PR per the modified Response Evaluation Criteria in Solid Tumours (RECIST) for pleural mesothelioma or RECIST v1.1 for peritoneal mesothelioma and assessed by computed tomography (CT) or magnetic resonance imaging (MRI). Complete Response (CR) corresponds to disappearance of all target lesions, and Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions. Overall Response (OR) = CR + PR.

  • Duration of Response by Treatment Arm [ Time Frame: Duration of response from the first documentation of objcetive response (confirmed CR or PR) to the first documented disease progression, assessed up to 14 weeks after the initial response. ]
    Duration of response will be defined as the duration from the first documentation of complete response (CR), partial response (PR) to the first documented disease progression.

  • Disease Control Rate by Treatment Arm [ Time Frame: Time from randomization to disease progression or death, whichever occurs first, assessed up to 3 years. ]
    Disease control rate (DCR) is defined as the proportion of participants with best response of complete response (CR), partial response (PR), or stable disease (SD) of ≥ 12 weeks duration

  • Durable Disease Control Rate by Treatment Arm [ Time Frame: Time from randomization to disease progression or death, whichever occurs first, assessed up to 3 years. ]
    Durable disease control rate (DDCR) is defined as the percentage of participants with best response of complete response (CR), partial response (PR), or stable disease (SD) of ≥ 6 months duration

  • Number of Participants Reporting Any Adverse Event [ Time Frame: Day 1- 90 days post dose ]
    Any untoward medical occurrence in a patient or clinical investigation participants administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.

  • Number of Participants Reporting Any Serious Adverse Events [ Time Frame: Day 1 to 90 days post dose ]
  • Number of Participants With Positive Anti-drug Antibodies [ Time Frame: Week 5 ]
    The immunogenicity titer is reported for samples confirmed positive for the presence of anti tremelimumab antibodies.

Detailed Description:

This is a Phase 2b, randomized, double-blind, parallel-group study. Subjects with unresectable pleural or peritoneal malignant mesothelioma will be randomized in a 2:1 ratio to receive either tremelimumab or placebo.

Randomization will be stratified by EORTC status (low-risk vs high-risk), line of therapy (second vs third), and anatomical site (pleural vs peritoneal). This study plans to use the EORTC to stratify subjects into high or low risk groups in order to ensure balanced randomization to the different treatment groups. For subjects in whom pemetrexed was contraindicated or not tolerated or not an approved therapy (eg, peritoneal mesothelioma), prior therapy with a first-line platinum-based regimen is required. Approximately 564 subjects will be enrolled at study centers in multiple countries.

The study consists of a screening period, a treatment period, and a 90-day follow-up period.
