Summary

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

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 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).

Eligibility

Yes No Not Sure

Inclusion Criteria

Subjects with histopathological confirmation of primary or secondary malignant cutaneous neoplastic lesions, or oral cavity mucosal tumors, or superficial soft tissue sarcoma. Confirmation obtained within 6 months of planned treatment
Subjects with a tumor size ≤ 7 centimeters in the longest diameter
Targetable lesion must be technically amenable for complete coverage (including margins) by the DaRT seeds
Brachytherapy indication validated by a multidisciplinary team
Patients who have either failed first-line treatment, or are medically unfit for standard of care (surgery, external-beam radiation therapy or chemotherapy), or refuse standard of care
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
WBC ≥ 3500/μl, granulocyte ≥ 1500/μl

Exclusion Criteria

Subject has a tumor of Keratoacanthoma histology
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
Any medical or psychiatric illness which in the opinion of the investigator would compromise the patient's ability to tolerate this treatment or interfere with the study endpoints
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
