IsoRay's Cesium-131 Lung Cancer Treatment Reports 96% Success in Local Control and 100% Survival at 5 Years in High Risk Patients in Newly Published Report

Cesium-131's Outstanding Lung Cancer Results Take on Other Treatment Forms Including Stereotactic Radiation

RICHLAND, WA--(Marketwired - May 20, 2015) - IsoRay, Inc. (NYSE MKT: ISR), a medical technology company and innovator in seed brachytherapy and medical radioisotope applications, today announced the on-line publication of the first major peer reviewed study showing improved results using IsoRay's Cesium-131 seeds in the treatment of lung cancer.

IsoRay CEO Dwight Babcock commented, "We are extremely excited to have our Cesium-131 isotope seeds and mesh used in the treatment of non-small cell lung cancers with such outstanding patient outcomes. Notable physicians, including the authors of this study, are seeking better solutions and outcomes for their patients. We are continuing to develop our product offerings internally with support from these industry leaders. With every success that has been reported, the medical community is rapidly becoming aware of the innovative alternative our Cesium-131 products offer to cancer patients."

Dr. Bhupesh Parashar MD, of Weill Cornel Medical College, is lead author of the publication titled: 'Analysis of Stereotactic Radiation vs. Wedge Resection vs Wedge Resection Plus Cesium-131 Brachytherapy in Early-stage Lung Cancer'. The study noted that the survival rate at 5 years was exceptional for the Cesium-131 group, which included many high risk patients, and Cesium-131 added no noticeable side effects. Treatment with Cesium-131 was performed at the time of the surgery as a single treatment, in contrast to another treatment option, external radiation, which requires numerous hospital visits.

Babcock said, "Published studies are the final step to commercialization as leaders in the medical arena recognize the important need for a new powerful weapon in the battle against cancer. This latest publication, in conjunction with other recent published reports on metastatic brain cancer and gynecological cancers, are proving Cesium-131's time is now. Not only does Cesium-131 work but it is a single application providing improved quality of life for the patient."

IsoRay's various products, including Cesium-131 seeds, sutured seeds, stranded mesh and the GliaSite® radiation therapy system, give physicians the ability to directly place a specified dosage of radiation in areas where cancer is most likely to remain after completion of a tumor removal or by placing seeds within the prostate. The ability to precisely place a specified dose of radiation means there is less likelihood for damage to occur to healthy surrounding tissue compared to other alternative treatments. IsoRay's cancer fighting products diminish the ability of the tumor to recur, resulting in important benefits for patients in longevity as well as quality of life.

IsoRay is the exclusive manufacturer of Cesium-131. The pioneering brachytherapy therapy 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.
