Descriptive Information
Brief Title  ICMJE Retreatment With Intratumoral Diffusing Alpha Radiation Emitters
Official Title  ICMJE A Safety and Efficacy Study of Retreatment With Intratumoral Diffusing Alpha Radiation Emitters
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 re-treatment with 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 either recurrent or persistent disease following DaRT treatment. .

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 Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Skin Cancer

  • Subjects with a tumor size ≤ 5 centimeters in the longest diameter.
  • Target lesion technically amenable for full coverage with the Alpha DaRT seeds.
  • Brachytherapy indication validated by a multidisciplinary team.
  • Measurable disease according to RECIST v1.1.
  • Subjects over 18 years old.
  • Subjects' ECOG Performance Status Scale is < 2.
  • Subjects' life expectancy is more than 6 months.
  • Platelet count ≥100,000/mm3.
  • AST and ALT ≤ 2.5 X ULN
  • WBC ≥ 3500/μl, granulocyte ≥ 1500/μl
  • International normalized ratio of prothrombin time ≤1.4 for patients not on Warfarin
  • Creatinine ≤2.3 mg/dL.
  • Women of childbearing potential (WOCBP) will have evidence of negative pregnancy test before the Ra-224 implantation and are required to use an acceptable contraceptive method to prevent pregnancy for 3 months after brachytherapy.
  • Subjects are willing to sign an informed consent form.

Exclusion Criteria:

  • Patients undergoing systemic immunosuppressive therapy excepting intermittent, brief use of systemic corticosteroids
  • Known hypersensitivity to any of the components of the treatment.
  • Clinically significant cardiovascular disease, e.g. cardiac failure of New York Heart Association classes III-IV, uncontrolled coronary artery disease, cardiomyopathy, uncontrolled arrhythmia, uncontrolled hypertension, or history of myocardial infarction in the last 12 months.
  • Patients with uncontrolled intercurrent illnesses including, but not limited to an active infection requiring systemic therapy or a known psychiatric or substance abuse disorder(s) that would interfere with cooperation with the requirements of the trial or interfere with the study endpoints.
  • Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
  • 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.
  • 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
  • High probability of protocol non-compliance (in opinion of investigator)
  • Subjects not willing to sign an informed consent
