Clinical Trials

Inclusion Criteria:

• Patients with recurrent cutaneous SCC histologically confirmed who have failed at least first line standard of care therapy who are not indicated for surgery andstan dard radiation therapy, or non alpha radiation brachytherapy technologies, and for whom no curative systemic treatment is available.
• Central histopathological confirmation within 6 months of enrollment provided no tumor treatment occurred between the biopsy and enrollment.
• Measurable disease according to RECIST v 1.1.
• Ability to undergo a CT scan.
• Tumor size ≤ 7 cm, at the longest diameter.
• Single lesion per subject.
• Targeted lesion must be technically amenable for complete coverage (including margins) by the DaRT seeds.Targets will be deemed technically amenable for complete coverage if there are entry and exit vectors for placement that are not hindered by bone or major vessels or other vital organs (e.g., eye).

• Patients, male and female, with reproductive potential (including women who are menopausal for less than a year and not surgically sterilized), must practice acceptable effective methods of birth control, such as barrier methods, condom or diaphragm with spermicide or abstinence. Birth control should be continued for 3 months after the DaRT insertion visit.
• Women with childbearing potential must provide a negative pregnancy test during the screening period and up to V1, prior to the DaRT insertion procedure.
• Blood tests values:
  • Leucocytes ≥ 3000mm^3;
  • Absolute neutrophil count ≥ 1500mm^3;
  • Platelets ≥ 100,000 mm^3;
  • Total bilirubin ≤ 1.5 x ULN (upper limit of normal);
  • Aspartate Aminotransferase (AST) ≤ 2.5 x ULN;
  • Serum Glutamic-Oxaloacetic Transaminase (SGOT) ≤ 2.5 x ULN;
  • Serum Glutamic-Pyruvic Transaminase (SGPT) ≤ 2.5 x ULN;
  • Alkaline Phosphatase ≤ 2.5 x ULN;
  • Creatinine ≤ 2.0 x ULN or Creatinine Clearance ≥ 60 ml/min.;
  • INR (International Normalized Ratio) or Prothrombin time ≤ 1.5 x ULN.

Exclusion Criteria:

• Distant or nodal metastatic disease (according to the TNM [tumor, nodes, and metastases] staging system - N+ or M1 patients are excluded).
• T4 disease or perineural spread of disease
• Previously untreated cutaneous SCC indicated for surgery or radiation.
• Mucosal, vulvar, anal and penile SCC.
• Inability to fully cover the entire volume with DaRT seeds
• Inability to place DaRT seeds into tumor due to inaccessibility by presence of bones or major vessels or vital organs
• Inability to undergo a CT scan
• Patients undergoing systemic immunosuppressive therapy excepting intermittent, brief use of systemic corticosteroids.
• Patients receiving any of the following within 4 weeks of enrollment:
  • Antineoplastic systemic chemotherapy or biological therapy;
  • Immunotherapy;
  • Investigational agents other than the study intervention;
  • Radiation therapy;
  • Live vaccines within 30 days prior to the first dose of trial treatment and while participating in the trial.
• Longest tumor diameter > 7 cm.
• Tumor with keratoacanthoma histology.
• Known hypersensitivity to any component of treatment.
• Clinically significant cardiovascular disease; e.g., cardiac failure of New York Heart Association class III-IV, uncontrolled coronary artery disease, cardiomyopathy, uncontrolled arrhythmia, uncontrolled hypertension, history of myocardial infarction in the last 12 months.
• Any medical or Psychiatric illness, which in the opinion of the investigator would compromise the patient's ability to tolerate treatment and to adhere to the clinical trial protocol.
• Serious medical comorbidities that, in the opinion of the investigator, may affect subject compliance and/or interpretation of treatment safety or effectiveness.
• High probability of protocol non-compliance (in opinion of investigator).
• 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.
• Has a known additional malignancy that is progressing or requires active treatment.  Exceptions include basal cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
• Patients do not agree to use adequate contraception (vasectomy or barrier method of birth control) prior to study entry and for 3 months after the DaRT insertion visit.
• Breastfeeding or pregnant women.
• Tattoos or other identifying marks which can not be adequately hidden on digital photos
