BrachySciences Only Company To Offer All Three Isotopes For Low Dose Rate Prostate Brachytherapy

February 26, 2009 at 2:00 pm Leave a comment

BrachySciences, the leader in providing innovative medical devices for the treatment of early stage prostate cancer, has announced a distribution agreement with IsoRay Inc., manufacturer of Proxcelan™, the only Cesium-131 radioactive source available for brachytherapy. By adding the unique Cesium-131 source to its distribution portfolio of Advantage Iodine-125™ and the TheraSeed® Palladium-103 device, BrachySciences is now the only company capable of providing all three radioactive isotopes used in low dose rate (LDR) prostate brachytherapy.

The agreement leaves BrachySciences uniquely positioned to service the requirements of any physician performing LDR prostate brachytherapy. “We’re very excited about what the availability of all three isotopes means for physicians,” said Jim Matons, President, BrachySciences. “We’ll be able to effectively fulfill all of their LDR prostate brachytherapy needs. Not only will physicians have access to all three isotopes, but they will now be able to obtain them all in BrachySciences’ most advanced devices, such as AnchorSeed™, EchoStrand™, and VariStrand™, for any of their treatment techniques.”

Anthony G. Pasqualone, IsoRay Vice President of Sales and Business Development, added “We are extremely pleased to announce this agreement with BrachySciences. Proxcelan represents a major innovation in brachytherapy isotope offerings. As such, it only makes sense for us to extend the presence of Cesium-131 in brachytherapy by distributing Proxcelan through BrachySciences, which has a reputation for bringing innovative products to the industry. We are confident our agreement will offer a compelling option to physicians practicing brachytherapy.”

In addition to physicians, administrators and purchasing departments stand to benefit from the agreement. With access to all three isotopes and a diverse brachytherapy product portfolio capable of satisfying any pre-planned or real-time implant technique, BrachySciences has the ability to function as a solitary vendor and complete service provider to hospitals and clinics with LDR implant programs.

About IsoRay

IsoRay, Inc., through its subsidiary, IsoRay Medical, Inc., is the sole producer of the Cesium-131 brachytherapy seed, used to treat prostate and other cancers. The Cesium-131 seed offers a significantly shorter half-life than the two other isotopes commonly used for brachytherapy, which results in a substantially faster delivery of therapeutic radiation, lower probability of cancer cell survival, and reduction of the longevity of common brachytherapy side effects(a)(b). IsoRay is based in Richland, Washington. More information is available about IsoRay at
