FDA grants IDE clearance for next-phase trial of ‘Flash’ radiation therapy

A cancer-care technology company that was acquired by one of the world’s largest imaging OEMs a year ago has received an Investigational Device Exemption from the FDA.

The IDE will allow the company to advance its ongoing research into Flash therapy—which delivers ultra-high-dose radiation therapy in one second or less—as a firstline treatment for thoracic bone metastases.

Palo Alto, Calif.-based Varian, which became part of Siemens Healthineers in the first half of 2021, announced the go-ahead June 27.

The company says it will work on the technology in a trial called FAST-02. The acronym stands for FeAsibility Study of Flash therapy for the Treatment of symptomatic bone metastases.

Varian began clinically testing the technique in its FAST-01 trial and used data from that phase to earn the new IDE.

Varian says it expects to enroll 10 patients suffering with thoracic bone metastases for FAST-02, documenting evidence of safety and efficacy based on the patients’ self-reporting of side effects and pain relief.

The company quotes John Breneman, MD, who is leading the next-phase investigation.

“For the last decade, radiation oncologists have been exploring Flash therapy as an important opportunity to create a paradigm shift in the way we treat patients,” says Breneman, who is medical director of the Cincinnati Children’s/UC Medical Center Proton Therapy Center. “The FAST-01 trial laid the groundwork for the approval of FAST-02, and we are excited to continue the clinical research and evaluate Flash therapy in a new patient cohort.”

According to the June 27 announcement, this center opened in 2016 and played a key role in the city of Cincinnati’s hosting of the world’s first clinical trial of Flash proton therapy.
