About

A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for newly Diagnosed Breast Carcinoma patients with distant metastases

Full 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 sources [Ra-224 containing stainless-steel 316LVM tubes- (Alpha DaRT seeds)] inserted into malignant breast lesions.

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.

Histopathological confirmed invasive breast tumors with no involvement of skin will be treated using DaRT seeds.

The primary effectiveness endpoint of the study is the tumor response to DaRT treatment assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1) 9-11 weeks after DaRT seed insertion.

Safety will be assessed by the cumulative frequency, severity and causality of acute adverse events related to the DaRT treatment of adverse events (AEs) observed including the follow-up period.
