Alpha Tau Medical presented clinical results of its alpha radiation cancer treatment at ASTRO

Alpha Tau Medical Ltd., (Israel) presented preliminary clinical results of its alpha-radiation-based brachytherapy (Alpha DaRT) at ASTRO (American Society for Therapeutic Radiation Oncology) on October 23 in San Antonio, Texas, USA. HekaBio has partnered with Alpha Tau Medical to develop and commercialize the Alpha DaRT cancer treatment for solid tumors in Japan.

The clinical results carried out in Israel were from 15 subjects who completed follow-up for 30-45 days, resulting in an overall response rate of 100% and a complete response rate over 73%. Some of the subjects were elderly patients who were medically unfit for surgery or failed previous external beam radiation. It was demonstrated that the Alpha DaRT can be administered safely under local anesthesia in an outpatient setting for all of the patients, including the given sensitive cases.
