Alpha Radiation Emitters Device for the Treatment of Advanced Pancreatic Cancer

This is a prospective, single-center, open label, single arm study. The study is designed to evaluate the feasibility, safety and preliminary efficacy of intratumoral alpha radiation mediated treatment with Alpha DaRT seeds for the treatment of advanced pancreatic cancer.

The study will be comprised of a screening period, DaRT insertion visit, acute follow-up phase of 4-6 weeks and a long-term follow up phase of 24 months. The total duration of the study will be 24 months from the DaRT insertion procedure.

30 patients with advanced pancreatic cancer will be recruited by the investigational site.

Eligible patients who meet inclusion/exclusion criteria (as assessed during the screening period) will be invited to the site for the procedure of DaRT seeds insertion. The patients will be monitored for a period of 24 months post insertion.

Inclusion criteria

• Histologically and/or cytologically proven locally advanced (Stage II or III) or metastatic (Stage IV) pancreatic, adenocarcinoma
• Inoperable pancreatic cancer due to at least one of the following: a) unresectability, b) metastatic disease, c) medically unfit for surgery
• ECOG performance status ≤ 2
• Measurable lesion per RECIST (version 1.1) criteria
• Maximum lesion of 4cm in the longest diameter (including primary tumor and regional lymph nodes)
• ≥ 18 years of age
• Estimated life expectancy of at least 12 weeks
• Women of childbearing potential (WOCBP) will have evidence of negative pregnancy test
• Subjects are willing to sign an informed consent

Exclusion criteria

• Prior chemotherapy does not exclude the patient
• Prior abdominal radiation therapy
• Concomitant chemotherapy or immunotherapy
• Borderline resectable pancreatic cancer and medically fit for surgery
• Connective tissue disease (scleroderma, lupus)
• Patients with significant comorbidities that the treating physician deems may conflict with the endpoints of the study (e.g., poorly controlled autoimmune diseases, vasculitis, etc.)
• Patients undergoing systemic immunosuppressive therapy excepting intermittent, brief use of systemic corticosteroids
• Volunteers participating in another interventional study in the past 30 days which might conflict with the endpoints of this study or the evaluation of response or toxicity of DaRT
• High probability of protocol non-compliance (in opinion of investigator)
• Patients not willing to sign an informed consent form
• Women who are pregnant or lactating
