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 post DaRT insertion]
• Adverse Events [Срок оценки: Up to 24 Months]

Вторичные конечные точки (5)

• Change in tumor volume [Срок оценки: 9-11 weeks post DaRT insertion]
• DaRT seeds placement [Срок оценки: 1 Day of procedure]
• Change in quality of life [Срок оценки: Day 15, Day 30, Day 70, Day 180 post DaRT insertion]
• Change in quality of life [Срок оценки: Day 30, Day 70, Day 180 post DaRT insertion]
• Progression Free Survival [Срок оценки: 24 months post DaRT insertion]

• Patients undergoing systemic immunosuppressive therapy excepting intermittent, brief use of systemic corticosteroids
• Patient requires treatment which may conflict with the endpoints of this study including evaluation of response or toxicity of DaRT
• Volunteers participating in another interventional study in the past 30 days which might conflict with the endpoints of this study or the evaluation of response or toxicity of DaRT.
• Patients must agree to use adequate contraception (vasectomy or barrier method of birth control) prior to study entry, for the duration of study participation and for 3 months after discontinuing therapy.
• High probability of protocol non-compliance (in opinion of investigator).
• Subjects not willing to sign an informed consent.
• Women who are pregnant or breastfeeding.
