An Israeli medical technology company is set to begin testing its new radiation cancer therapy in leading medical centers in Italy. The Alpha DaRT (Dіffusіng Alpha-emіtters Radіatіon Therapy) device delivers high-precision alpha radiation that is released when radioactive substances decay inside the tumor and kills cancer cells while sparing the surrounding healthy tissue, the company says.
The company hopes to get approval from the European Commission by next year for the therapy.
Early results from an ongoing pre-clinical trial on patients with squamous cell carcinoma (SCC) tumors at the Rabin Medical Center in Israel and the IRST (Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori) in Italy showed a reduction in all tumor sizes and more than 70 percent of the tumors completely disappearing within a few weeks after treatment, NoCamels reported.
The therapy has already been tested on more than 6,000 animals and has been found “to be effective and safe for various indications, including tumors considered to be resistant to standard radiotherapy.” according to the breakthrough innovation news site NoCamels.
Alpha Tau Medical was founded in 2016 to focus on research and development as well as commercialization of its Alpha DaRT cancer treatment. The therapy was initially developed in 2003 by Professors Itzhak Kelson and Yona Keisari at Tel Aviv University.
According to the National Cancer Institute (NCI), cancers that are known collectively as head and neck cancers, or squamous cell carcinomas of the head and neck, usually begin in the squamous cells that line the moist, mucosal surfaces inside the head and neck (for example, inside the mouth, the nose, and the throat).
Head and neck cancers account for about 4% of all cancers in the United States, are more than twice as common among men as they are among women, and are more often diagnosed among people over age 50.
Cancers of the head and neck are further categorized by the area of the head or neck in which they begin including the oral cavity, pharynx (throat), larynx, paranasal sinuses and nasal cavity, and salivary glands. They can include hypopharyngeal cancer, laryngeal cancer, lip and oral, cavity cancer, metastatic squamous neck cancer with occult primary, nasopharyngeal cancer, oropharyngeal cancer, paranasal sinus and nasal cavity cancer, salivary gland cancer.
The Alpha DaRT treatment can be applied under local anesthesia in a short single session and can be combined with chemotherapy and immunotherapy to increase effectiveness, according to Alpha Tau Medical. The company reports Alpha DaRT can even trigger anti-tumor immunity for the elimination of distant metastases, NoCamels reported.
Clinical trials for Alpha DaRT will be conducted at the Sapienza University of Rome, which is initiating Alpha Tau’s clinical trial protocol for squamous cell carcinomas of the skin and oral cavity, and the IFO (Istituti Fisioterapici Ospitalieri), which is conducting its first study of Alpha DaRT for the treatment of cutaneous and mucosal malignant neoplasia (CMN).
Alpha Tau is also collaborating with key cancer physicians worldwide to investigate the Alpha DaRT as a treatment for other cancers, including pancreatic, breast and prostate, NoCamels reported.
