Brief Summary:
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for the treatment of newly diagnosed or Recurrent Breast Carcinoma in frail or elderly patients.

Condition or disease Intervention/treatment Phase
Breast Cancer Recurrent Breast Cancer Breast Carcinoma Device: Diffusing Alpha Radiation Emitters Therapy (DaRT) Not Applicable

Detailed Description:

This is a Prospective Open label Single arm multi-center interventional study. The study is designed to evaluate the Feasibility and Safety of DaRT seeds for the treatment of newly diagnosed or Recurrent Breast Carcinoma in frail or elderly patients.

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 24 months. The total duration of the study will be 24 months from the DaRT insertion procedure.

A total of 10 subjects will be enrolled from all breast cancer subtypes (HR+/HER-2-, HR+/HER-2+, HR-/HER-2-, and HR-/HER-2-.). No formal interim analysis is planned for this 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 24 months post insertion

Arm Intervention/treatment
Experimental: DaRT Seeds
Intratumoral Diffusing alpha-emitters Radiation Therapy (DaRT) Seeds
Device: Diffusing Alpha Radiation Emitters Therapy (DaRT)
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

Primary Outcome Measures :
  1. Feasibility -DaRT seed placement [ Time Frame: immediately following the insertion procedure ]
    Feasibility will be determined according to the Rate of successful placement of DaRT seeds via imaging

  2. Safety- Adverse events [ Time Frame: From Day 0 ]
    Safety will be determined according to the overall incidence of device related SAE'sgraded according to CTCAE v5.0 criteria

Secondary Outcome Measures :
  1. Efficacy - Control evaluation [ Time Frame: 3,6,12 and 24 months ]
    To evaluate efficacy, as determined by local control evaluation according to RECIST v1.1
