Key Insights

  • Leo Cancer Care announced FDA 510(k) clearance for Marie®, an innovative upright radiotherapy platform that combines patient positioning systems with CT scanning capabilities.

  • The system addresses traditional barriers to particle therapy adoption by eliminating rotating gantries, dramatically reducing infrastructure costs and simplifying installation processes.

  • Marie® is compatible with multiple treatment modalities including proton, carbon ion, BNCT and FLASH therapies, with evidence suggesting reduced anatomical shifts compared to supine treatments.

Leo Cancer Care, a leader in upright radiotherapy solutions, announced that its flagship product Marie® has received 510(k) clearance from the U.S. Food and Drug Administration. The Middleton, Wisconsin-based company's innovative platform represents a paradigm shift in particle therapy delivery, combining an upright patient positioning system with CT scanning capabilities while drastically reducing size and cost compared to existing particle therapy solutions.

Addressing Traditional Particle Therapy Barriers

Particle therapies such as proton and carbon ion therapy have long been considered the gold standard in radiation oncology. However, the cost, size, and complexity of conventional systems with large rotating gantries have historically limited widespread adoption.
"This clearance marks a major milestone not just for Leo Cancer Care, but for the future of cancer treatment," said Stephen Towe, CEO of Leo Cancer Care. "We've long believed there's a better, more human way to deliver radiotherapy. One that puts the patient at the heart of the treatment experience and embraces smarter, more compassionate design. Marie is the embodiment of that belief."
Leo Cancer Care's upright solution addresses these barriers by rotating the patient rather than the beam. Marie eliminates the need for a rotating gantry, dramatically reducing infrastructure costs, simplifying installation, and expanding access to this advanced level of care.

Versatile Treatment Platform

Marie is particle beam-agnostic, meaning it's compatible with a wide range of current and emerging treatment modalities, including proton, carbon ion, BNCT and FLASH therapies. The upright design opens new possibilities for treatment planning and delivery, particularly for tumors in the thoracic and abdominal regions.
When compared to supine treatments, evidence suggests anatomical shifts are reduced due to the gravitational direction, potentially improving treatment precision and outcomes.

Clinical Research and Future Development

Through collaborations with leading hospitals around the world, Leo Cancer Care is conducting clinical research and trials, laying a strong foundation for the widespread adoption of upright therapy as a new standard in radiotherapy.
"We are incredibly proud of the teams and collaborators who helped bring Marie to life," added Thomas 'Rock' Mackie, Co-founder and Board Chairman of Leo Cancer Care. "This is just the beginning. We're working closely with leading particle beam companies and institutions worldwide to explore how upright positioning can unlock new levels of precision and personalization in cancer care."
The FDA clearance positions Marie® to potentially transform the accessibility and delivery of advanced particle therapy treatments, addressing longstanding infrastructure and cost challenges that have limited the widespread adoption of these gold-standard cancer treatments.
