Health Technology Assessment Validates Extracranial Radiosurgery Treatments Particularly Those Delivered With CyberKnife(R)

French Health Authority Finds Clinical Benefits for Curative and Palliative Care

SUNNYVALE, Calif., May 31 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today that the French High Authority of Health -- Haute Autorite de Sante (HAS) -- issued a health technology assessment report validating extracranial radiosurgery treatment applications, particularly those delivered with the CyberKnife(R) Robotic Radiosurgery System. The report deemed clinical benefits with these extracranial applications a significant improvement compared to existing alternatives (2 on a scale of 5, with 1 being the most significant).

Health technology assessment (HTA) is used to evaluate the impact of medical technology on patients and healthcare organizations by measuring safety, efficacy, cost effectiveness and efficiency. The HTA program works to provide decision makers with high-quality information and is frequently used to make important decisions regarding reimbursement. It is also used in many countries to guide purchasing decisions.

HTA is an extremely strict process and sets a high standard for best practices in healthcare, in order to enhance safety, improve quality and reduce costs. HTA is now related to virtually every health policy process in France, and its role is becoming increasingly important within healthcare systems worldwide.

In recent years greater importance has been placed on HTA programs throughout the world in an effort to address rising healthcare costs and policy-makers desire for access to better decision-making processes. The report by the HAS was undertaken to define validated indications before patients start treatment using three CyberKnife Systems acquired thanks to a support by the French National Institute of Cancer (INCa).

"The positive HTA for extracranial radiosurgery applications as part of the evaluation process of the CyberKnife System marks a milestone in the growing worldwide clinical acceptance of this groundbreaking technology" said Euan S. Thomson, Ph.D., president and CEO of Accuray. "Validation by such an important, non-partisan authority is further demonstration that the market for radiosurgery is continuing to broaden and that the CyberKnife System is meeting the needs of patients and clinicians worldwide."

The HTA evaluation included analysis of 42 studies on the use of radiosurgery for extracranial indications and concluded that there is sufficient expected clinical benefit for the curative or palliative treatment of patients with spine tumors, and primary and metastatic lung tumors.

About the CyberKnife(R) Robotic Radiosurgery System

The CyberKnife System represents the next generation of radiosurgery systems, combining continual image-guidance technology with a compact linear accelerator that has the flexibility to move in three dimensions according to the treatment plan. This combination, which is referred to as intelligent robotics, extends the benefits of radiosurgery to the treatment of tumors anywhere in the body. The CyberKnife System autonomously tracks, detects and corrects for tumor and patient movement in real-time during the procedure, enabling delivery of precise, high dose radiation typically with sub-millimeter accuracy.
