Registration Number

Lead Sponsor

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).
