IsoRay Misrepresents Its Business Practices

According to the complaint, defendants made materially false and misleading statements regarding the success of its Cesium-131 seeds in treating lung cancer.  Specifically, IsoRay issued a press release touting the on-line publication of the first major peer reviewed study showing improved results using its Cesuim-131 seeds in the treatment of lung cancer.  Subsequently, TheStreet.com published an article asserting that IsoRay selectively edited findings from the published study to make its Cesium-131 product seem better than it really is to make up for the company's inability to deliver revenue growth.  Over the next several days, IsoRay fell $1.84 per share, or 42%, on heavy trading volume.
