 The purpose of this research study is to investigate the safety of an active implantable radiological medical device OncoSilTM, when implanted into patients with pancreatic cancer, in conjunction with Standard of Care SOC chemotherapy. OncoSilTM, is an experimental treatment and carries the active treatment radioactive Phosphorous 32P inside inactive silicon particles. Once implanted, the OncoSilTM Microparticles will stay in the tumour permanently. The purpose of OncoSilTM, is to deliver the action of 32P directly into a targeted tumour to destroy cancer cells.
