Item 8.01.   Other Events.
 
On October 19, 2011, Neoprobe Corporation (the "Company") issued a press release announcing that its New Drug Application ("NDA") for Lymphoseek® (tilmanocept) had been accepted for review by the U.S. Food and Drug Administration (FDA). The Company submitted the Lymphoseek NDA on August 10, 2011.

The Company seeks U.S. clearance to market Lymphoseek for use in Intraoperative Lymphatic Mapping ("ILM"), a surgical oncology procedure in which lymph nodes draining the area around a tumor are identified and biopsied to determine if cancer has spread to the lymph nodes. According to the American Cancer Society, approximately 230,000 new cases of breast cancer and 70,000 new cases of melanoma are expected to be diagnosed in the United States in 2011.   The Lymphoseek NDA has proposed use of the agent in the identification of lymphatic tissue.

The NDA submission for Lymphoseek includes results from two Phase 3 studies of Lymphoseek, NEO3-05 and NEO3-09, performed in patients with either breast cancer or melanoma. The primary endpoint for both the NEO3-05 and NEO3-09 studies was the concordance (or the rate of agreement) on a lymph node count basis of Lymphoseek with vital blue dye, a long-standing, FDA-approved, on-label agent for lymphatic mapping and appropriate “Truth Standard” comparator for registration purposes. In both of the Phase 3 studies (NEO3-05, NEO3-09), the concordance of Lymphoseek to vital blue dye was highly statistically significant (p<0.0001). Lymphoseek met all primary and secondary endpoints across both studies.

Secondary endpoints were also assessed, including the false negative rate (or failed detection rate) of Lymphoseek versus vital blue dye.  This analysis evaluated the ability of vital blue dye and Lymphoseek to detect lymph nodes that contained cancer cells, as determined by pathology evaluation.  In both studies combined, vital blue dye exhibited a failed detection rate of more than 20%, whereas Lymphoseek showed a failed detection rate of approximately 1%, or twenty-fold lower than vital blue dye, a difference that was also highly statistically significant (p<0.002).  Because the key objective of performing ILM is to identify cancer cells when they are present in lymph nodes, reduction of the failed detection rate is important.

In more than 500 subjects receiving Lymphoseek to date, including those studied as a part of the NEO3-05 and NEO3-09 studies, no drug-related serious adverse events or clinically significant drug-related adverse events have been reported.  Lymphoseek works by binding to a specific receptor found on the surface of dendritic cells and macrophages, which reside in lymph-nodes.  This receptor-targeted property of Lymphoseek enables it to attach to and remain within lymph nodes.  To date Lymphoseek is the first and only receptor-targeted agent developed specifically for ILM.
