Mevion’s Proton Therapy System Gains Approval of Chinese Regulators

Mevion Medical Systems has won approval from the China’s National Medical Products Administration (NMPA) for its MEVION S250i Proton Therapy System.

The MEVION S250i is the first compact, integrated single-room proton therapy system that was cleared in the United States and now is the first approved in China. Its design combines a superconducting proton accelerator with an integrated gantry, resulting in a smaller footprint and reduced energy consumption compared to conventional proton therapy systems. The system also features HYPERSCAN pencil beam scanning technology, which allows for faster and precise tumor targeting, and Adaptive Aperture pMLC, which further minimizes damage to healthy tissue, potentially leading to fewer side effects for patients.

“We are thrilled to receive NMPA approval for the MEVION S250i,” Mevion Medical Systems CEO Dr. Tina Yu said. “This approval is a testament to our commitment to providing innovative and accessible cancer treatment solutions. We believe that the advancement of the MEVION S250i will make a significant contribution to the fight against cancer in China.”

The MEVION S250i offers several advantages over conventional proton therapy systems, including:

• Compact size: The system’s smaller footprint makes it easier to integrate into existing hospitals and clinics.
• Reduced cost: The MEVION S250i is more affordable than conventional proton therapy systems, making it accessible to a wider range of patients.
• Faster treatment times: The system’s HYPERSCAN technology enables faster treatment times, which can improve patient comfort and convenience.
• Enhanced precision: The Adaptive Aperture pMLC technology ensures precise dose delivery to the tumor while minimizing damage to surrounding healthy tissue.

Mevion aims to expand access to proton therapy in China by providing comprehensive services to customers such as training, education, and ongoing maintenance.
