About this study

Official title: A Feasibility and Safety Study of Intratumoral Diffusing Alpha Radiation Emitters on 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, 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.

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Feasibility - DaRT seed placement

    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.

    Measured: Day 0 (Day of insertion)

  2. Safety - Adverse events

    Assessment of the frequency, severity and causality of acute 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

    Measured: 3 months

  3. Safety - Adverse events

    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

    Measured: 3 to 24 months

Secondary outcomes (6)
  1. Efficiency - Short-term effect

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

    Measured: 4-6 weeks after DaRT seeds insertion

  2. Tissue damage evaluation

    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).

    Measured: Day -14 to 60 days after insertion

  3. Efficiency - Long-term effect

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

    Measured: 2 years following DaRT seeds insertion

  4. Stent durability

    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

    Measured: Day of DaRT insertion up to 24 months.

  5. Change in quality of life: EORTC-QLQ-C30

    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).

    Measured: Day -14 to 60 days after insertion

  6. Change in quality of life: QLQ-PAN26

    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).

    Measured: Day -14 to 60 days after insertion

Questions about this trial

What is this clinical trial studying?

A study testing Radiation: Diffusing Alpha Radiation Emitters Therapy (DaRT) in people with Pancreatic Cancer and Unresectable Pancreatic Cancer, run by Alpha Tau Medical LTD. at 2 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 2 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Feasibility - DaRT seed placement (time frame: Day 0 (Day of insertion)). The study lists 3 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2025.
