Flash therapy is an experimental treatment modality delivering radiotherapy at ultra-high dose rates to treatment volumes in typically <1 second.

Flash therapy could be one of the most significant advancements in cancer treatment in decades.

Flash therapy is an experimental treatment modality delivering radiotherapy at ultra-high dose rates to treatment volumes in typically <1 second. Compared to conventional therapy, preclinical studies in mice have shown equivalent or better tumor control, reduced normal tissue toxicity, and immunological advantages.

Varian’s FlashForward™ Consortium is formed from institutions around the world to establish preclinical study designs, develop technical solutions, and share research protocols to help advance the science and clinical translation of Flash therapy.

World’s First Flash Clinical Trial

Feasibility Study of Flash Proton Radiotherapy for the Treatment of Symptomatic Bone Metastases (FAST-01)

FAST-01 is a first-in-human clinical trial evaluating the feasibility and safety of Flash radiotherapy in patients with painful bone metastases of the extremities. A standard palliative dose fractionation regimen of 8 Gy in a single fraction is delivered with a 250MeV transmission proton beam at Flash dose rates. The FAST-01 study has completed enrollment at Cincinnati Children’s Hospital Medical Center (PI: Dr. J. Breneman). The design of the follow-up trial FAST-02 is underway.

Study details:

  • Patients with Bone metastases of the extremities
  • Enrollment for the study is open now
  • Study uses a modified ProBeam for the IDE
  • In partnership with Cincinnati Children’s/University of Cincinnati Medical Center, Proton Therapy Center

Trials using Flash radiotherapy for lung cancer and other malignancies are currently being developed. Using Flash treatment for these cancers could deliver higher cancer-killing doses without causing inordinate side effects, which would be a real advance.

Dr. John Breneman Medical Director at Cincinnati Children’s Hospital Medical Center UC Health Proton Therapy Center

Flash therapy has the potential to be practice-changing and drastically improve the experience of cancer care for a new generation of patients. The launch of the first Flash clinical trial, a project that has come to fruition after years of intensive study, is an important milestone in the progress of radiation therapy.
