Perspective Therapeutics, Inc., formerly known as Isoray, Inc., is a medical technology and radiopharmaceutical company that is pioneering advanced treatment applications for cancers throughout the body. The Company is the sole producer of Cesium-131 brachytherapy seeds and has a proprietary technology that utilizes the isotope lead-212 to deliver powerful alpha radiation specifically to cancer cells via specialized targeting peptides. The Company is also developing complementary imaging diagnostics that incorporate the same targeting peptides which provide the opportunity to personalize treatment and optimize patient outcomes. This “theranostic” approach enables the ability to see the specific tumor and then treat it to potentially improve efficacy and minimize toxicity associated with many other types of cancer treatments.
