Varian Medical Systems Makes Equity Investment and Obtains Option to Purchase Augmenix

PALO ALTO, Calif. and WALTHAM, Mass., May 12, 2011 /PRNewswire/ -- Varian Medical Systems, Inc. (NYSE: VAR), the world's leading supplier of medical technology for treating cancer with radiotherapy, and privately-held Augmenix, Inc. today announced that they have reached an agreement under which Varian will make a $15 million minority equity investment in Augmenix, a company that is developing hydrogel products to improve outcomes in radiation oncology.  The agreement also provides Varian with the exclusive option to acquire the rest of Augmenix provided certain agreed-upon milestones have been met.

Augmenix' lead product, SpaceOAR™ System, is designed to be used in men scheduled to undergo radiotherapy for prostate cancer.  The product is injected between the prostate and rectum under ultrasound guidance.  Once injected, the liquid hydrogel solidifies within seconds to move the rectum away from the prostate, helping to reduce the amount of radiation that goes to the rectum during therapy.  After treatment, the hydrogel dissolves and is absorbed by the body.

SpaceOAR System is commercially approved for sale by Augmenix in select European countries and Australia.  In the United States, SpaceOAR is under clinical investigation and will require the submission of a premarket approval application, or PMA, and approval by the Food and Drug Administration before being commercialized.

The objective, with radiotherapy, is to deliver as much dose as possible to a tumor while minimizing exposure of surrounding healthy tissues.  During prostate radiotherapy, avoiding the rectum can be a special challenge because the rectal wall borders the prostate gland.  While studies have shown that advanced forms of conformal radiotherapy such as intensity-modulated radiotherapy (IMRT) reduce the amount of dose received by the rectum, (1,2)  outcomes may be further improved with a better physical separation between the prostate and the rectum during treatment.

Amar Sawhney, chief executive officer and director of Augmenix said, "The SpaceOAR System is designed to provide a unique and cost effective way to manage potential reduction in injury to organs at risk, such as the rectum, during radiotherapy of the prostate.  Better targeting may enable radiation oncologists to deliver more radiation per treatment, thus decreasing the total number of treatments required (hypofractionation), resulting in significant healthcare savings. We are excited to have Varian, with its significant market leading expertise in radiation therapies, appreciate this potential for improvement of cancer care, and help us bring these advances to market."

"By enabling urologists and radiation oncologists to shift anatomy into optimal positions prior to irradiation, the SpaceOAR System represents a therapeutic paradigm shift that could potentially lead to improved radiotherapy outcomes, including lower complication rates and higher tumor control rates," said John Adler, M.D., Varian's chief of new clinical applications.  "Investing in Augmenix fits perfectly with our commitment to provide physicians with novel technologies that offer cancer patients both highly efficacious and cost-effective treatments."
