About this study
Official title: A Feasibility and Safety Study of Intratumoral Diffusing Alpha Radiation Emitters for the Treatment of Advanced Pancreatic Cancer
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for advanced pancreatic cancer
Read the detailed description
This is a Prospective, interventional, open label, single arm, multiple center study. The study is designed to evaluate the feasibility and safety of the 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- 8 weeks and a long-term follow up phase of 3 months. The total duration of the study will be 3 months from the DaRT insertion procedure.
15 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 3 months post insertion

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Radiation: Diffusing Alpha Radiation Emitters Therapy (DaRT)Device
An intratumoral insertion of radioactive sources [Ra-224 containing stainless-steel 316LVM tubes- (Alpha DaRT seeds)]. The seeds release by recoil into the tumor short-lived alpha-emitting atoms
| Study group | Role | What they receive |
|---|---|---|
| DaRT Seeds | Experimental | Intratumoral Diffusing alpha-emitters Radiation Therapy (DaRT) Seeds Receives: Device: Radiation: Diffusing Alpha Radiation Emitters Therapy (DaRT) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility - DaRT seed placement
Feasibility will be determined according to the rate of successful placement of DaRT seeds via imaging
Measured: From Day 0
Safety - Adverse events
Safety will be determined according to the overall incidence of device related SAE's graded according to CTCAE v5.0 criteria
Measured: up to 3 months
Secondary outcomes (3)
Efficacy -Alpha DaRT seeds
The secondary objective of the study is to evaluate the efficacy of the Alpha DaRT seeds for advanced pancreatic cancer patients with respect to quality of life and tumor size.
Measured: 1 month and 3 months]

Where is the study taking place?
The record lists 2 sites in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Feasibility - DaRT seed placement (time frame: From Day 0). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
