A Study of TNFerade™ Biologic With 5-FU and Radiation Therapy for First-Line Treatment of Unresectable Locally Advanced Pancreatic Cancer

The primary purpose of this study is to assess the safety and effectiveness of TNFerade™ Biologic when administered concurrently with 5-FU and radiation therapy as first-line treatment of unresectable locally advanced pancreatic cancer. TNFerade™ is a replication deficient adenovirus vector containing the gene for TNF-alpha controlled by a chemoradiation inducible promoter. This allows the expression of TNF-alpha to be greatest in the area receiving radiation. TNF-alpha is a cytokine that has been shown to have potent anti-cancer activities but, due to systemic toxicity, could not be delivered at effective doses. TNFerade™ Biologic is a novel way of selective delivery of TNF-alpha to tumor cells. TNFerade™ Biologic will be injected during five weekly injection sessions, concomitant with radiation and 5-FU. TNFerade™ Biologic will be administered by direct intratumoral injection using a percutaneous approach (PTA) or endoscopic ultrasound (EUS).
