Brief Summary:
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for Malignant Cutaneous Tumors

Condition or disease Intervention/treatment Phase
Skin Cancer Cutaneous Tumor Cutaneous Metastasis Device: DaRT- Diffusing Alpha-emitters Radiation Therapy Not Applicable

Detailed Description:

This will be a prospective, open label, single arm, multi- center study, assessing the safety and effectiveness of diffusing alpha emitters radiation therapy (DaRT) delivered through radioactive seeds inserted into the tumor.

This approach combines the advantages of local intratumoral irradiation of the tumor, as used in conventional brachytherapy, with the power of the alpha radiation emitting atoms, that will be introduced in quantities considerably lower than radiation therapy already used in patients.

Cutaneous lesions with histopathological confirmation of malignancy will be treated using DaRT seeds.

Reduction in tumor size 9-11 weeks following DaRT insertion will be assessed. Safety will be assessed by the frequency, severity and causality of all Adverse Events (AE).

Arm Intervention/treatment
Experimental: DaRT Seeds Intratumoral Diffusing alpha-emitters
An intratumoral insertion of securely fixed seeds loaded with Radium-224. The seeds release by recoil short-lived alpha-emitting atoms into the tumor.
 Device: DaRT- Diffusing Alpha-emitters Radiation Therapy
Seed(s) loaded with Radium-224 for local intratumoral irradiation with the destructive power of alpha particles


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The objective response rate to DaRT treatment [ Time Frame: up to 9-11 weeks ]
    Assessment of tumor response rate using the Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1)


Secondary Outcome Measures :
  1. Tumor volume [ Time Frame: up to 9-11 weeks ]
    Assessment of the reduction in tumor volume based on imaging tests

  2. DaRT seeds placement [ Time Frame: Day of DaRT insertion procedure ]
    Assessment of the DaRT seed placement by localization of the DaRT seed in the tumor using CT imaging

  3. Change in quality of life as assessed by the Skindex-16 questionnaire [ Time Frame: up to 9-11 weeks ]
    Assessment of patient reported health-related Quality of Life (QoL) outcomes using the Skindex-16 questionnaire

  4. Disease-Free Survival (DFS) rate [ Time Frame: up to 24 months ]
    Assessment of Disease-Free Survival

  5. Change in quality of life as assessed by the Skin Cancer Index (SCI) questionnaire [ Time Frame: up to 9-11 weeks ]
    Assessment of patient reported health-related Quality of Life (QoL) outcomes using the Skin Cancer Index (SCI) questionnaire.


Other Outcome Measures:
  1. Adverse Events [ Time Frame: up to 24 months ]
    Assessment of the frequency, severity and causality of adverse events related and not related to the DaRT treatment. Adverse events will be assessed and graded according to Common Terminology and Criteria for adverse events (CTCAE) version 5.0.
