IsoRay, Inc. announced the signing of an exclusive Manufacturing and Supply Agreement with GT Medical Technologies, Inc., for proprietary Cesium-131 seeds embedded in collagen tiles. The term of the Supply Agreement is 10 years. Under the Supply Agreement, IsoRay will exclusively manufacture and supply a brachytherapy product, known as GammaTile™, that incorporates its proprietary Cesium-131 seeds within customizable carriers, configured as squares or rectangles, for the treatment of brain tumors. The exclusive Supply Agreement follows the signing of a Collaborative Development Agreement in early 2017 with GT Medical Technologies, in which the companies agreed to equally share costs as they collaborate on refining GammaTile’s manufacturing process, work together to achieve 510(k) regulatory clearance, and obtain reimbursement from the Centers for Medicare and Medicaid Services (CMS) for the GammaTile™ product.
