About this study

Official title: A Feasibility and Safety Study of Intratumoral Diffusing Alpha Radiation Emitters for the Treatment of Recurrent Lung Cancer

A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for treatment of recurrent Lung Cancer .

Read the detailed description

This is a prospective , interventional, open label, single arm, single center study.

The study is designed to evaluate the Feasibility and Safety of DaRT seeds for the treatment of Recurrent Lung 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.

A total of 10 subjects will be enrolled to the study .

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

What is being measured

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

  1. Feasibility - DaRT seed placement

    Feasibility will be determined according to the rate of successful placement of DaRT seeds via imaging

    Measured: From Day 0-Day 90

  2. 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: From Day 0-Day 90

Secondary outcomes (2)
  1. Efficacy - Alpha DaRT seeds

    Local control evaluation according to RECIST v1.1

    Measured: 1 month and 3 months

  2. Efficacy - Alpha DaRT seeds

    Tumor Coverage

    Measured: Day 0-Day 90

Questions about this trial

What is this clinical trial studying?

A study testing Radiation: Diffusing Alpha Radiation Emitters Therapy (DaRT) in people with Recurrent Lung Cancer and Lung Cancer, run by Alpha Tau Medical LTD. at 1 site in Israel.

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 16 inclusion and 12 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: looking for participants now, as of the sponsor's last update on 16 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

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?

Contact Liron Dimnik (+972237377000, LironD@alphatau.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Feasibility - DaRT seed placement (time frame: From Day 0-Day 90). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jun 2026.
