IsoRay develops, manufactures, and sells isotope-based medical products and devices for the treatment of cancer and other malignant diseases in the United States. The Company produces Proxcelan Cesium-131 brachytherapy seeds for the treatment of prostate, lung, head and neck, colorectal, brain, pelvic/abdominal, and gynecological cancers, as well as ocular melanoma. It also offers GliaSite radiation therapy system, a balloon catheter device, which is used to treat brain cancer, including primary and recurrent gliomas and metastatic brain tumors.

The Complaint alleges that throughout the Class Period, Defendants made false and/or misleading statements regarding IsoRay's Celsium-131 isotope seeds and mesh for the treatment of non-small cell lung cancers.

On May 20, 2015, IsoRay issued a press release touting 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.

On May 21, 2015, published an article on IsoRay asserting that the Company selectively edited findings from a published study in the May 20th Press Release to make its Cesium-131 product seem better than it really is.

On this news, shares of IsoRay fell $1.10 per share or over 35% to close at $2.02 per share on May 21, 2015, damaging investors.
