PanCO: This pilot study will evaluate the radiological implant (OncoSil) in combination with standard chemotherapy, for the treatment of locally advanced pancreatic cancerAn Open Label, Single Arm Pilot Study of OncoSil™ Administered to Study Participants With Unresectable Locally Advanced Pancreatic Adenocarcinoma, Given in Combination With FOLFIRINOX or Gemcitabine+Nab-paclitaxel Chemotherapies

Inclusion

1. Histologically or cytologically proven adenocarcinoma of the pancreas.
2. Unresectable locally advanced pancreatic carcinoma. Patients with technically resectable tumours (T1-T3) will also be eligible, if they are deemed unresectable due to medical comorbidities or refusal of surgery.
3. Pancreatic target tumour diameter of ≥ 2.0 cm (shortest axis) to ≤ 6.0 cm (longest axis), as qualified by the central reading centre.
4. An ECOG Performance Status of 0 to 1 and Karnofsky Performance Status of 80 - 100.
5. Study participants ≥ 18 years of age at screening.
6. To commence first-line standard FOLFIRINOX or gemcitabine+nab-paclitaxel chemotherapy (per standard of care according to the approved prescribing schedule), within 14 days post enrolment, with OncoSil™ implantation to occur during the fourth (4th) week of the first chemotherapy cycle.
7. Provide signed Informed Consent.
8. Willing and able to complete study procedures within the study timelines.
9. Adequate renal function: serum creatinine less than 1.5 x upper limit of normal (ULN).

10. Adequate liver function: serum liver transaminases ≤ 3 × ULN and serum bilirubin

    ≤ 1.5 × ULN*.

    *For study participants with recent biliary obstruction treated by drainage (e.g. stent), serum bilirubin of > 1.5 x ULN will be accepted for study entry provided that serial levels demonstrate clear improvement. In addition, chemotherapy should not be commenced until serum bilirubin is ≤ 1.5 × ULN.

11. Adequate bone marrow function: white blood cells (WBCs) ≥ 3,000/mm3, absolute neutrophil count (ANC) ≥ 1,500/mm3, haemoglobin ≥ 9 g/dL, and platelets ≥ 100,000/mm3.
12. Life expectancy of at least 3 months at the time of screening as judged by the investigator.
13. Treated with or eligible to commence prophylactic treatment with a proton-pump inhibitor prior to implantation, and to continue to receive treatment for at least 6 months post implantation.
14. Not pregnant, and if of childbearing potential, agrees to use adequate birth control (hormonal or barrier method of birth control or abstinence) prior to study entry and during the study and agrees not to donate sperm or ova, for the duration of the study and 12 months post implantation of the investigational device.
