What this Trial Is About
Researchers are evaluating a new treatment approach using intratumoral diffusing alpha radiation emitter devices for advanced pancreatic cancer. This prospective, interventional, open-label, single-arm, multicenter study aims to assess the feasibility and safety of these DaRT seeds in patients with locally advanced or metastatic pancreatic adenocarcinoma who have received chemotherapy or are medically unfit for it, and whose tumors are not suitable for surgery or who refuse surgery. The treatment involves the insertion of radioactive DaRT seeds directly into the tumor. These seeds release short-lived alpha-emitting atoms inside the tumor. The study includes a screening period, a procedure visit for DaRT seed insertion, an acute follow-up phase lasting 4 to 8 weeks, and a long-term follow-up phase of 3 months after insertion. A total of 15 patients will be enrolled and monitored throughout these phases. Participants will undergo evaluations including safety monitoring for adverse events up to 3 months, and assessments of treatment feasibility based on seed placement. Researchers will also measure efficacy outcomes at 1 month and 3 months after insertion and immediately following the procedure. The total participation duration is about 3 months from the time of DaRT insertion, with close follow-up to track treatment effects and patient safety.
