Phase II, Single-Arm, Multi-Site study. All subjects will receive the investigational agent, GC1008 in 3 week cycles of treatment 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.

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.

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.

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.

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.
