Brief Summary

A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for advanced pancreatic cancer.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
Feasibility - DaRT seed placementDay 0 (Day of insertion)

Assessment of the DaRT seed placement within the tumor or less than 5 mm from the tumor using CT imaging on the day of DaRT insertion.

Safety - Adverse events3 to 24 months

Assessment of the frequency, severity and causality of Late AEs and SAEs related to DaRT seeds insertion. AEs and SAEs will be assessed and graded according to Common Terminology and Criteria for Adverse Events (CTCAE) version 5.0. The follow up will be carried out by phone calls every 2 months during the time between 3 to 24 months after DaRT seeds insertion

Secondary Outcome Measures
NameTimeMethod
Change in quality of life: EORTC-QLQ-C30Day -14 to 60 days after insertion

Assessment of patient reported health-related Quality of Life (QoL) outcomes after DaRT treatment, using QoL questionnaires EORTC-QLQ-C30 (version 3.0). Scale range in score from 0 (best) to 100(worst).

Tissue damage evaluationDay -14 to 60 days after insertion

Measuring CA19-9 as a marker to tissue damage. Elevation during treatment, and reduction as a result of tumor ablation. Serum levels of CA 19-9 can be measured using chemiluminescent assay on an Unicel DxI 800 analyzer (BeckmanCoulter, Brea, CA, USA).

Efficiency - Long-term effect2 years following DaRT seeds insertion

Assessment of the overall survival (OS) following DaRT seeds insertion

Stent durabilityDay of DaRT insertion up to 24 months.

Stent durability will be assessed by the time elapsed from DaRT insertion to the need for follow-up referral for ERCP for stent change due to tumor ingrowth

Efficiency - Short-term effect4-6 weeks after DaRT seeds insertion

Assessment of the objective response rate (ORR) following DaRT seeds insertion using CT scan

Change in quality of life: QLQ-PAN26Day -14 to 60 days after insertion

Assessment of patient reported health-related Quality of Life (QoL) outcomes after DaRT treatment, using QoL questionnaires QLQ-PAN26. The module comprises 26 questions assessing pain, dietary changes, jaundice, altered bowel habit, emotional problems related to pancreatic cancer, and other symptoms (cachexia, indigestion, flatulence, dry mouth, taste changes).
