An Exploratory Trial to Evaluate Efficacy and Safety for Combination Treatment of Adenovirus Double Suicide Gene Therapy

A Single Arm, Open, Exploratory Clinical Trial to Evaluate Efficacy and Safety for Combination Treatment of Replication Competent Adenovirus Double Suicide Gene Therapy(Theragene®,Ad5-yCD/mutTKSR39rep-ADP) and Radiation Therapy in Patients

Replication-competent Adenovirus-mediated Double Suicide Gene Therapy (Theragene®,Ad5-yCD/mutTKSR39rep-ADP) showed safety and anti-cancer effect in patients with pancreatic cancer in phase I study.

From the experience of phase I study, the safety and efficacy of combination with standard chemotherapy and radiation therapy with Theragene treatment will be assessed in this study.
