Study Description

Brief Summary: This investigator initiated study with a medical device aims to assess the safety and feasibility of percutaneous injected holmium-166 microsphere brachytherapy in patients with irresectable pancreatic cancer.

Detailed Description: Objective: To test the feasibility and safety of minimally invasive CT-guided percutaneous holmium-166 microsphere brachytherapy in patients suffering from irresectable pancreatic cancer. Study design: This is a single centre, prospective, safety and feasibility study with a medical device in a maximum of 6 patients. Study population: Patients diagnosed with pathologically proven pancreatic adenocarcinoma, who are ineligible for exploratory surgery or surgical resection of the tumour after 8 cycles of systemic therapy or less in case of unacceptable toxicity, patient refusal or patients who are ineligible for systematic therapy. Intervention (if applicable): A radioactive medical device will be implanted by CT-guided percutaneous injection. The medical device in question are beta-minus (β-) and gamma(γ) emitting holmium-166 poly(L-lactic acid) microspheres (166Ho-PLLA-MS, HoMS) in a 0.1% Pluronic or cellulose based suspension. Main study parameters/endpoints: The main endpoint is to establish the feasibility and safety of CT-guided percutaneous intratumoural implantation of HoMS in irresectable pancreatic adenocarcinoma. Feasibility is established by evaluating the average tumour absorbed dose in Gray (Gy) calculated on SPECT and comparing to the pre-operative planning. Intratumoural microsphere distribution, absorbed tumour dose and non-target absorbed tumour dose are analysed using MRI and CT quantification. Safety is evaluated using the Common Terminology Criteria for Adverse Events (CTCAE v5.0), events deemed 'unlikely', 'probably' or 'definitely' related to the implantation procedure or implanted medical device. As exploratory endpoints, tumour response (RECIST1.1), pain (NRS) and Quality of Life is evaluated. Total follow-up is 16 weeks.
