RATIONAL: Preliminary results fron the Study MESOT-TREM-2012 indicate a promising activity of tremelimumab in malignant mesothelioma (MM) patients.

PURPOSE: The proposed study MESOT-TREM-2012 aims to explore the efficacy of a more intensive schedule of treatment with tremelimumab in 29 MM patients. Subjects will receive investigational product every 4 weeks (wks) for 6 doses, followed by doses every 12 wks until confirmed disease progression.

Primary Outcome Measures:
  • To determine the objective response [ Time Frame: Weeks 24 ]
    The objective response is defined as a confirmed complete response (CR), or partial response (PR) according to the modified RECIST Criteria for pleural mesothelioma and the immune-related (ir) Response Criteria

Secondary Outcome Measures:
  • Disease control rate (DCR) [ Time Frame: 1 year ]
    DCR is the proportion of treated subjects that achieved confirmed CR or PR or stable disease (SD) The DCR is assessed using the modified RECIST Criteria for pleural mesothelioma umor assessment and the the immune-related response criteria

  • Safety [ Time Frame: 3 years ]
    The assessment of safety includes serious and non-serious adverse events according to NCI-CTC criteria version 3.0. In addition, laboratory evaluation, abnormal vital signs and physycal examination findings are also included.

  • Progression free survival [ Time Frame: 1 years ]
    Progression free survival is computed from the first day of study treatment to the day of documented progression according to the modified RECIST Criteria for pleural mesothelioma or death, whichever occurs first

Estimated Enrollment: 29
Study Start Date: July 2012
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: single arm with Tremelimumab
Tremelimumab: 10mg/Kg ev day 1 every 4 weeks for 6 doses in induction phase, then every 12 weeks in maintenance phase until disease progression of severe toxicity
Drug: Tremelimumab
Tremelimumab is administered as endovenous infusion
Other Name: CP-675,206

Detailed Description:

Primary endpoint:

1) To assess the rate of objective clinical complete response (CR) or partial response (PR)

Secondary endpoints:

  1. To define toxicity profile according to NCI CT-CAE V. 3
  2. To assess the overall survival (OS)
  3. To estimate disease control rate (DCR) (proportion of patients with best response of CR+PR+SD) according to the modified Recist criteria
  4. To assess the progression-free survival in treated patients according to modified Recist criteria
  5. To evaluate qualitative and quantitative changes in cellular and humoral immune responses
