Advanced hydrogel technology from Augmenix used during prostate cancer radiation therapy now available to cancer treatment centers in Japan.

BEDFORD, Mass.–(BUSINESS WIRE)–May 30, 2017–

Augmenix, Inc., a medical technology company that develops, manufactures, and sells proprietary absorbable hydrogels that separate and protect organs at risk during radiotherapy, today announced that it has received Shonin approval from the Japanese Ministry of Health, Labor and Welfare (MHLW) to market its SpaceOAR® System in Japan. SpaceOAR hydrogel is an absorbable prostate-rectum spacer that reduces rectal injury during prostate radiotherapy.

“SpaceOAR hydrogel is a major advance to significantly reduce risks of prostate cancer radiation therapy and positively impact patients’ quality of life,” said Keiichi Nakagawa, M.D., Ph.D., University of Tokyo Hospital. “We are very excited to have this technology available in Japan and look forward to its use in treating our prostate cancer patients,” said Dr. Nakagawa.

SpaceOAR is CE marked in the EU, FDA cleared, approved in Australia and licensed in Canada.

“We now have extensive clinical data showing that SpaceOAR hydrogel helps to significantly reduce the risk of rectal and urinary toxicities and loss of sexual function associated with radiation therapy for men with prostate cancer,” said John Pedersen, CEO of Augmenix. “We are very pleased that the Shonin approval will enable physicians in Japan to offer SpaceOAR hydrogel as an option for men with prostate cancer who want to reduce their risk of radiotherapy side effects including rectal toxicity, incontinence and loss of sexual function.”

Radiation therapy in the treatment of prostate cancer can cause unintended injury to adjacent healthy tissue, which can lead to bowel, urinary and sexual symptoms that can affect patient health and quality of life. With SpaceOAR hydrogel, physicians can place a hydrogel barrier to separate the prostate from surrounding healthy tissue. The minimally invasive procedure can be performed in a hospital, surgery center, outpatient clinic or doctor’s office. SpaceOAR hydrogel is initially implanted as a liquid that solidifies into a soft gel that pushes the prostate and rectum apart. It remains stable for three months and then is gradually absorbed by the body following radiation therapy.

In January 2017, Augmenix announced three-year post-treatment data from a prospective, randomized, multi-center, patient-blinded clinical trial showing that patients treated with SpaceOAR hydrogel technology prior to prostate cancer radiotherapy demonstrated significant rectal (bowel), urinary, and sexual benefit through three years of follow up. Overall patient wellness at three years was assessed by looking at the percent of patients with clinically significant declines in all three QOL areas (bowel, urinary and sexual). Fully 20% (1 in 5 patients) of men in the Control arm had clinically significant declines in all three QOL areas compared to only 2.5% (1 in 40 patients) of men in the SpaceOAR arm (p=0.002). Among men who were potent at baseline, the analysis showed that SpaceOAR treated men were better able to maintain erections sufficient for intercourse through 3 years of follow-up (p=0.03). Of the men treated with SpaceOAR, 66.7% could achieve erections sufficient for intercourse at three years compared to 37.5% in the Control arm, a 77.8% improvement.

About SpaceOAR System

Radiation therapy in the treatment of prostate cancer can cause unintended radiation injury to adjacent healthy tissue (organs at risk). This injury can lead to a range of bowel, urinary and sexual symptoms that can affect patient health and quality of life during radiotherapy, and for years afterward. In recent years, radiation oncologists have considered use of “spacing” techniques to reduce the risk of radiation injury to surrounding tissue during radiotherapy. SpaceOAR hydrogel is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of SpaceOAR System to reduce the radiation dose delivered to the anterior rectum. The SpaceOAR System is injected as a liquid into the space between the prostate and rectum where it pushes the structures apart and then solidifies into a soft hydrogel. The hydrogel remains stable for three months during radiation therapy then liquefies and is completely absorbed by the body. See the Instructions for Use for complete information on potential risks, warnings and precautions.
