IsoRay Announces Iodine Distribution Agreement with GE Subsidiary, Oncura

RICHLAND, Wash., Dec. 3--(HSMN NewsFeed)--IsoRay, Inc. (Amex: ISR ) announced today that it has signed a distribution agreement with Oncura to distribute the I-125 brachytherapy seed, OncoSeed™.

Dwight Babcock, Chairman and CEO stated, “By adding I-125 seeds to our prostate product offering we can now be a full service provider to our customers. OncoSeed brings with it a substantial and well documented track record of efficacy. While we believe that Cesium-131 adds an important new dimension to brachytherapy for a variety of anatomic sites including prostate, we see strategic value in supporting our customers that have not yet converted all their practice to Cesium-131.”

Mr. Babcock added, “We believe the ability to offer I-125 seeds will allow us to expand our Cesium-131 sales through GPO contracts which require multiple sources from a single provider. Previously, by not having two sources, we have been excluded from bidding on large GPO contracts and offering Cesium-131. The ability to obtain GPO contracts should open up a large group of physicians who want to use our Cesium-131 brachytherapy seeds.”

OncoSeed, known by physicians as Model 6711, has been available since it was launched in 1993. It has the largest market share of any I-125 brachytherapy seed worldwide.

Mr. Babcock concluded, “This is an important step to support our physician partners and this agreement allows IsoRay to supply I-125 seeds to its Canadian partner, Inter V Medical, thus providing additional revenue and margins to IsoRay.”

About IsoRay

IsoRay, Inc., through its subsidiary, IsoRay Medical, Inc., is the sole producer of the Cesium-131 brachytherapy seed.

The Cesium-131 seed offers a significantly shorter radiation half-life than the two other isotopes commonly used for brachytherapy, which results in a substantially faster delivery of therapeutic radiation, a theoretically improved radiation delivery against aggressively replicating cancer(a), and the potential for a reduced longevity of common brachytherapy side effects(b).

Cesium-131 is currently used in the treatment of prostate cancer(c) and ocular melanoma(d), among other cancerous conditions.

IsoRay is based in Richland, Washington. More information is available about IsoRay at www.isoray.com.
