IsoRay Makes First Cesium-131 Delivery for Treatment of an Inoperable Brain Cancer Afflicting a Young Child in Peru

IsoRay Raced To Deliver Cesium-131 Seeds To Treat A 7 Year Old Girl Who Was In Desperate Need Of Treatment.

Richland, WA (July 14, 2014) - IsoRay Inc. (NYSE MKT: ISR), a medical technology company and innovator in seed brachytherapy and medical radioisotope applications, today announced the first Cesium-131 seed shipment to Peru for the treatment of a Glioma brain tumor located near the brainstem.

Dr. Carlos Alvarez, Neurosurgeon at Instituto de Columna y Cerebro in Lima, successfully completed the world’s first stereotactic brain implant utilizing Cesium-131 seeds. Dr.Alvarez said “The patient was a 7 year old female who was diagnosed with a 3 centimeter inoperable Glioma brain tumor that was positioned close to the brainstem. Due to the size and tumor location, surgery and delivering high dose radiation using radiosurgery was not an attractive option.” Following the procedure Dr. Alvarez reported that there were no postoperative complications and the young girl was awake with no additional neurological deficit.

IsoRay CEO Dwight Babcock stated “These cases pull on your heart strings and IsoRay’s team rose again to the challenge in support of physicians worldwide and patients in need. By placing custom made Cesium-131 within the tumor, a very high dose can be delivered while sparing other critical structures in the brain and brainstem. IsoRay’s ability to deliver our isotope required the timely cooperation of Peruvian governmental agencies and our distributor BioProPeru. Thankfully the early reports from Dr. Alvarez are very rewarding to those who worked so hard on this case and we hope for continued success. We are extremely pleased with the exceptional results a growing number of thought leaders and major medical centers are experiencing throughout the U.S. and internationally as Cesium-131 receives more widespread adoption. We believe Cesium-131′s ability to fight cancer with new delivery options while improving the quality of life for the men, women, and children who are battling these devastating cancers distinguishes it from other treatment options.”

IsoRay is the exclusive manufacturer of Cesium-131. The pioneering brachytherapy is one of the most significant advances in internal radiation therapy in 20 years. Cesium-131 allows for the precise treatment of many different cancers because of its unrivaled blend of high energy and its 9.7 day half-life (its unequaled speed in giving off therapeutic radiation).

In addition to its CMS codes, Cesium-131 is FDA-cleared and holds a CE mark for international sales in seed form for the treatment of brain cancer, prostate cancer, lung cancer, ocular melanoma cancer, colorectal cancer, gynecologic cancer, head and neck cancer and other cancers throughout the body. The treatment can be deployed using several delivery methods including single seed applicators, implantable strands and seed sutured mesh, and several implantable devices including the GliaSite® radiation therapy system, the world’s only liquid radiation balloon catheter device used in the treatment of brain cancer.
