Alpha Radiation Emitters Device (DaRT) for the Treatment of Cutaneous, Mucosal or Superficial Soft Tissue Neoplasia.
- Conditions
- Soft Tissue NeoplasmSkin CancerMucosal Neoplasm of Oral Cavity
- Registration Number
- NCT03889899
- Lead Sponsor
- Alpha Tau Medical LTD.
- Brief Summary
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for superficial cutaneous, mucosal or soft tissue neoplasia
- Detailed Description
This will be a prospective, open label, single arm, controlled study, assessing the safety and efficacy 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.
Superficial lesions with histopathological confirmation of malignancy will be treated using DaRT seeds.
Reduction in tumor size 70 days after DaRT insertion will be assessed. Safety will be assessed by the incidence, severity and frequency of all Adverse Events (AE).

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Primary Outcome Measures
Name Time Method Adverse Events Time Frame: 9-11 weeks post DaRT insertion. The incidence, frequency, severity and causality of acute adverse events related to the DaRT treatment
Tumor response to DaRT 9-11 weeks after DaRT seed insertion. Assessment of the rate of malignant cutaneous, mucosal or superficial soft tissue tumors response using the Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1)
- Secondary Outcome Measures
Name Time Method Change in quality of life Screening, DaRT removal and day 70 visits. Assessment of patient reported health-related Quality of Life outcome after DaRT, using QoL questionnaire Skin Cancer Index (SCI) questionnaire score. An overall score ranging from 0 (best) to 100 (worst).
Assessment of the reduction in tumor volume 9-11 weeks follow-up visit. Assessment of the reduction in tumor volume based on CT / PET-CT measured tumor volume
DaRT seeds placement. Day of insertion procedure. Assessment of the DaRT seeds placement by localization of the DaRT seeds in the tumor using CT imaging on the day of DaRT insertion.
