Alpha Radiation Emitters Device (DaRT) for the Treatment of Cutaneous, Mucosal or Superficial Soft Tissue Neoplasia.

Официальное название

A Safety and Effectiveness Study of Intratumoral Diffusing Alpha Radiation Emitters for the Treatment of Malignant Cutaneous, Mucosal or Superficial Soft Tissue Neoplasia

Обзор

A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for superficial cutaneous, mucosal or soft tissue neoplasia

Подробное описание

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).

Вмешательства

• Устройство Radiation: Diffusing Alpha Radiation Emitters Therapy (DaRT)
  An intratumoral insertion of a seed(s), loaded with Radium-224, securely fixed in the seeds. The seeds release by recoil into the tumor short-lived alpha-emitting atoms.

Первичные конечные точки

• Tumor response to DaRT [Срок оценки: 9-11 weeks after DaRT seed insertion.]
• Adverse Events [Срок оценки: Time Frame: 9-11 weeks post DaRT insertion.]

Вторичные конечные точки (4)

• Assessment of the reduction in tumor volume [Срок оценки: 9-11 weeks follow-up visit.]
• DaRT seeds placement. [Срок оценки: Day of insertion procedure.]
• Change in quality of life [Срок оценки: Screening, DaRT removal and day 70 visits.]
• Change in quality of life [Срок оценки: Screening, DaRT removal and day 70 visits.]
