Brief Summary:

Malignant pleural mesothelioma (MPM) is a cancer with high mortality rate and few therapeutic options.essentially all patients usually progress and die subsequently to a first line therapyl. There is strong evidence that the immune system is deeply involved in the biogenesis of MPM and that an imbalance in pro-inflammatory cytokines and exhausted adaptive T-cell mediated immune response are the main causes of neoangiogenesis, progression and metastatisation processes.Numerous Phase II-III clinical trials are underway evaluating Durvalumab either as monotherapy or combination with evidence of activity in a wide range of solid tumors. Durvalumab has received FDA approval as second line treatment in patients with locally advanced or metastatic urothelial carcinoma.

Given these prospects for PD-L1 Ab, a Phase II study is proposed in order to evaluate the activity and safety of Durvalumab in advanced pretreated MPM.

Detailed Description:

Malignant pleural mesothelioma (MPM) is a cancer with high mortality rate and few therapeutic options. Its incidence is growing fast worldwide and is associated with asbestos exposure, a well known cancerogenic factor driving the development of this cancer. Generally MPM is diagnosed at an advanced inoperable stage and most frequently the only therapeutic approach is palliative chemotherapy. Platinum-pemetrexed doublets prolong significantly median overall survival (OS) and median progression free survival (PFS) with respect to platinum alone and are considered the only therapeutic option in a first line setting. Unfortunately, essentially all patients usually progress and die subsequently to a first line therapyl. There is strong evidence that the immune system is deeply involved in the biogenesis of MPM and that an imbalance in pro-inflammatory cytokines and exhausted adaptive T-cell mediated immune response are the main causes of neoangiogenesis, progression and metastatisation processes. Newer immunotherapeutic agents act on regulatory molecules expressed on immune cells in order to increase T cell activity and immune response against tumor. The anti-cytotoxic T lymphocyte antigen 4 (anti-CTLA4) demonstrated activity and a long-term disease control (DC) rate in advanced pretreated MPM in phase II study even if these results are not confirmed in more recently Phase IIb randomized trial versus placebo (DETERMINE study). Antibodies against Programmed Death 1 receptor (PD-1) and its ligand (PD-L1) are highly promising new agents regulating immune check-point processes. In particular the interaction of these agents takes place peripherally more than in the lymphoid tissue and may explain the higher response rate and lower adverse immune effects in comparison to antiCTLA4 agents. AntiPD-L1 antibodies are widely studied in many Phase I-II trials in different advanced pretreated solid tumors independent of tumor PD-L1 expression, with promising results and long-term survival. Ongoing melanoma and lung cancer phase III trials would probably better define the role of this class of drugs in clinical practice. Durvalumab is a human IgG1 antibody which binds specifically to PD-L1, preventing binding to PD-1 and CD80. Numerous Phase II-III clinical trials are underway evaluating Durvalumab either as monotherapy or combination with evidence of activity in a wide range of solid tumors. Durvalumab has received FDA approval as second line treatment in patients with locally advanced or metastatic urothelial carcinoma.

Given these prospects for PD-L1 Ab, a Phase II study is proposed in order to evaluate the activity and safety of Durvalumab in advanced pretreated MPM.

Drug Information available for: Durvalumab

Arm Intervention/treatment
Experimental: Durvalumab arm

Patients will receive Durvalumab at the dose and regimens described above every 4 weeks until evidence of disease progression or occurrence of unacceptable toxicity.

Patients who show evidence of disease progression but appear to tolerate Durvalumab well, for whom no other treatment options exist and who, at the judgement of the investigator, may still enjoy clinical benefit, will be classified as failures and offered the possibility to continue treatment with extended follow up.

Drug: Durvalumab
Durvalumab in monotherapy as second line treatment




Primary Outcome Measures :
  1. Proportion of survived patients at 16 weeks [ Time Frame: 16 weeks ]
    Proportion of patients alive and free from progression or death at 16 weeks (PFS 16 w) calculated from the start of treatment (Durvalumab).


Secondary Outcome Measures :
  1. Progression free survival [ Time Frame: 16 weeks ]
    defined as the time from treatment start to progression of disease or death from any cause; in absence of an event, patients will be censored at the time of the latest date of assessment. If the patient has no evaluable visits or does not have baseline data they will be censored at 1 day.

  2. overall survival [ Time Frame: 16 weeks ]
    defined as the time from treatment start to death from any cause; in absence of an event, patients will be censored at the time of the latest date of assessment. If the patient has no evaluable visits or does not have baseline data they will be censored at 1 day.

  3. Objective response rate [ Time Frame: 16 weeks ]
    defined as the proportion of patients with complete response (CR) or partial response (PR) according to CT assessment using the RECIST v1.1 criteria modified for MPM (Modified RECIST). Independent central review will be used to confirm investigator ORR.

  4. Tumour growth index [ Time Frame: 16 weeks ]
    defined as the ratio between PFS and the time from treatment start to progression of disease in first-line treatment

  5. Evidence of Number of Adverse Events [ Time Frame: 16 weeks ]
    Evaluated based on frequency, type and severity of reported AEs, immune related irAE, clinical laboratory assessments, vital signs and physical examination. Adverse events will be encoded and graded using NCI-CTCAE version 4.03.

  6. Exploratory endpoint [ Time Frame: 16 weeks ]
    PD-L1 IHC expression in tumor samples and tumor infiltrating lymphocytes (TIL), measured with the validated ABCAM 28-8 assay IHC assay optimized for use on the automated BenchMark UTRA platform (Ventana Medical Systems, Tucson, AZ, USA).
