Accuray Announces Tomo® C Registration Submission to China's National Medical Products Administration

SUNNYVALE,Calif.,Nov. 1,2022 -- Accuray Incorporated (NASDAQ: ARAY) announced today that the registration dossier for the CNNC-Accuray joint venture Tomo® C radiation therapy system for the Type B market has been submitted to the Chinese National Medical Products Administration (NMPA). This milestone aligns with the timeline communicated by Accuray during the company's Q4 FY2022 earnings call. The availability of Tomo C is subject to review and approval by the NMPA. The new made in China system,designed specifically to expand access to precise radiation treatments to more cancer patients in China,is the first joint venture product.

The number of new cancer cases diagnosed in China is anticipated to increase by approximately 50 percent from 2020 to 20401,with increases in the incidence of not just lung cancer,but also colorectum,breast and prostate cancers2. Radiation therapy is one of the primary treatment options for lung,breast and prostate cancers,reinforcing the need for innovative new approaches that effectively manage the disease while minimizing the risk of side effects and their impact on quality of life.

"The submission of the Tomo C dossier is an important step for the CNNC-Accuray joint venture and represents an important growth catalyst for Accuray. I'm confident that the system will significantly enhance the joint venture's product portfolio and ability to compete in the large and rapidly growing Type B segment in the future. The team's focus on ensuring we have the right products to address the needs of the Chinese radiation therapy market – the fastest growing in the world – will enable more people in China to get the care that is essential to their long-term health," said Suzanne Winter,president and chief executive officer of Accuray.

The TomoTherapy® platform is the first in the world capable of integrated helical fan beam imaging and radiation delivery,providing greater control of the radiation dose so it conforms precisely to the tumor and provides superior normal tissue preservation,enabling delivery of conventionally fractionated to ultra-hypofractionated treatments. The system is capable of treating all standard radiation therapy indications including breast,prostate,lung,abdominal,and head and neck cancers,in addition to complex treatments such as total marrow irradiation.

"This submission and the manufacture of a locally made TomoTherapy platform device underscores Accuray's commitment to the joint venture. I believe Tomo C will meet the requirements of the majority of Chinese customers who need a radiation delivery system that is effective and fast. This first China-made system will enable Chinese customers to offer highly precise radiation therapy to more patients each day," said Dr. Roger Cao,president & general manager APAC at Accuray.
