Brief Summary:
This study is being conducted to evaluate the overall safety and effectiveness of an investigational drug, GC1008, in patients with mesothelioma. An investigational drug is one that has not been approved by the FDA. Approximately 40 people will be enrolled on this study at the University of Pennsylvania (Main Institution/Coordinating Site) and the University of Chicago (Participating Institution). We expect about 20 subjects to be enrolled at each institution.

Condition or disease Intervention/treatment Phase
Pleural Malignant Mesothelioma Drug: GC1008 Phase 2

Detailed Description:

Primary: - To assess progression-free survival rate at three months.

Secondary: - To determine the toxicity and safety of systemic infusion of anti-TGF beta antibody at three-week dosing intervals. - To assess time to progression and overall survival - to assess response rate using Modified RECIST Criteria for Mesothelioma Additional Objectives: - To assess efficacy using serial measurements of serum [and intrapleural, if indwelling catheter in place] biomarkers, including serum-mesothelin related peptide (SMRP/Mesomark®) and osteopontin. - To assess systemic [and intrapleural if indwelling catheter in place] humoral anti-tumor immune responses after repeated anti-TGF beta antibody instillation. - To assess systemic [and intrapleural, if indwelling catheter in place] TGF beta, and other cytokine levels after repeated anti-TGF beta antibody instillation. - To assess biologic response measurements of TGF beta blockade from serum tests and from pleural fluid or biopsy tissue if this is available.

Arm Intervention/treatment
Experimental: Investigational drug infusion-for safety and effectiveness
Phase II, Single-Arm, Multi-Site study. All subjects will receive the investigational agent, GC1008 in 3 week cycles of treatment
Drug: GC1008
GC1008 is a human IgG4 kappa monoclonal antibody capable of neutralizing all mammalian isoforms of TGFbeta (i.e., beta1, beta 2 and beta 3). GC1008 is a high affinity antibody with dissociation constants (Kds) of 1.8 nM, 2.8 nM and 1.4 nM for TGF1,2,and 3, respectively.
Other Name: IgG4 kappa monoclonal antibody

Primary Outcome Measures :
  1. 3-month Progression Free Survival Rate [ Time Frame: 3 months ]
    The fraction of subjects surviving 3 months without disease progression.

Secondary Outcome Measures :
  1. Toxicity and Safety of Systemic Infusion of Anti-TGF Antibody [ Time Frame: 18 months ]
    The toxicity and safety of systemic infusion of anti-TGF antibody at three-week dosing intervals. Number subjects with Grade 2 and Grade 3/4 treatment related toxicities.

Other Outcome Measures:
  1. Time to Progression and Overall Survival [ Time Frame: 18 months ]
    Assessment of time to disease progression and overall survival

  2. Response Rate Using Modified RECIST Criteria for Mesothelioma [ Time Frame: 18 months ]
    Response and progression will be evaluated in this study using the international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in RECIST. The response assessment is based on the presence, absence, or unequivocal progression of the lesions.

  3. Number of Participants With a Change of Serum Biomarkers After Therapy [ Time Frame: 18 months ]
    Evaluation of changes after treatment therapy to a number of potential blood biomarkers of TGF-β effect (serum osteopontin, serum hyaluronan, serum MMP-1, serum MMP-7, serum IL-6, plasma CCL18, plasma VEGF, and plasma PAI-1). Animal models predict acute changes in TGF-β levels in blood associated with changes in serum biomarkers.

  4. Number of Participants With Systemic Humoral Anti-tumor Immune Response After Repeated Anti-TGFβ Antibody Instillation [ Time Frame: 18 months ]
    Comparing antibody bands in pre-treatment versus post-treatment serum

  5. Assessment of Systemic TGFβ After Repeated Anti-TGFβ Antibody Installation [ Time Frame: 18 months ]
    The number of participants with significant change in percentage of circulating CD4+ T regulatory cells, marked by expression of FOXP3 after treatment. TGFβ has been implicated in the formation of T regulatory cells, and the blockade of TGFβ in animal models can inhibit the formation of T regulatory cells.

  6. Biologic Response Measurements of TGFβ Blockade [ Time Frame: 3 weeks ]
    Number of participants who demonstrated upregulation of NK cell receptors 3 weeks after treatment. There are data that show anti-TGFβ antibodies can upregulate NK cell receptors in patients with chronic viral infections. TGFβ blockade was measured in samples of serum tests and from pleural fluid or biopsy if available.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Pathologically [histologically or cytologically] documented pleural malignant mesothelioma.

Patients must have had at least one, but no more than two prior systemic therapies, at least one of which contained pemetrexed.

  • Documented progressive disease evaluable by Modified RECIST criteria. [Progressive symptoms after 1st line therapy in the absence of objective progression are acceptable as a criterion for enrollment]. Patients who have had previous extrapleural pneumonectomy and disease recurrence will be eligible if they have no other exclusion criteria.
  • ECOG Performance status of 0 or 1.
  • Greater or equal to 18 years of age.
  • Male and female patients of child-producing potential must agree to use effective contraception while enrolled on study and receiving the experimental drug, and for at least 3 months after the last treatment.
  • Women of childbearing potential must have a negative serum or urine pregnancy test within 1 week prior to beginning treatment on this trial.
  • Must be able and willing to give written informed consent. Patients may not be consented by a durable power of attorney.
  • Serum albumin greater or equal to 2.5
  • Adequate organ function
  • Patients must have negative tests for human immunodeficiency virus (HIV) and for hepatitis viruses B and C (antibody and/or antigen) unless the result is consistent with prior vaccination or prior infection with full recovery.
  • At the time of enrollment, patients must be greater than 3 weeks since major surgery, radiotherapy, chemotherapy (greater or equal to 6 weeks if they were treated with a nitrosourea, mitomycin or monoclonal antibody), immunotherapy, or biotherapy/targeted therapies and recovered from the toxicity of prior treatment to less than or equal to Grade 1, exclusive of alopecia. Concurrent non-protocol cancer therapy is not permitted. (In patients who received long acting agents, a treatment free interval of 2 half lives should be considered.) Note: Although a patient can be entered by these criteria, if a patient is less than 3-6 months from radiotherapy or talc pleurodesis, FDG-PET scanning will not be useful. 12).

Exclusion Criteria:

  • Known central nervous system (CNS) metastases, meningeal carcinomatosis, malignant seizures, or a disease that either causes or threatens neurologic compromise (e.g., unstable vertebral metastases).
  • Presence of pericardial effusion
  • Rapidly re-accumulating, symptomatic malignant pleural effusions status-post thoracentesis or pleural catheter insertion that requires immediate mechanical or chemical pleurodesis for adequate palliation.
