NOTEWORTHY:

-- IsoRay Medical received Food & Drug Administration (FDA) approval to market its Cs131 Seed for the treatment of prostate cancer and other malignancies in March 2003.

-- The Cs131 Seed by IsoRay Medical combines the beneficial characteristics of a short half-life and high energy, giving it significant clinical advantages over Iodine-125 and Palladium-103, the brachytherapy isotopes commonly used in LDR cancer treatment today. When placed inside or near a tumor, Cs131 Seeds deliver radiation directly to cancer cells while reducing or eliminating damage to surrounding tissue.

-- Initial production is occurring through facilities contracted with the Pacific Northwest National Laboratory and the Department of Energy in Richland, Washington. Production will increase in the third quarter of 2005, when IsoRay Medical opens a fully automated manufacturing facility in Richland. Construction of the new IsoRay Medical facility is expected to begin in March 2005, and the company expects to employ 250 people when it is running at full capacity.

-- Low-dose brachytherapy (from the Greek prefix "brachy," meaning "short" or "close") is a convenient and cost-effective cancer treatment that employs the direct placement of radioactive seeds into or near the tumor. The seeds, about the size of an uncooked grain of rice, are injected into the prostate gland and benefit the patient by providing a high radiation dose to the cancer cells while minimizing the amount of radiation to the surrounding healthy tissue and body organs. Brachytherapy seeds containing the radioactive isotope Iodine-125 were first implanted into a cancer patient in 1967.

-- IsoRay Medical intends to first market its seed for prostate cancer patients, although the treatment holds promise for other types of cancer, including breast, brain, liver, head and neck cancers, and other malignant disease.
