ASCO Presentations Reinforce Lymphoseek Clinical Development Approach and Regulatory Pathway

- Company Remains Confident in Regulatory Pathway for Lymphoseek -

DUBLIN, Ohio--()--Neoprobe Corporation (NYSE Amex: NEOP), a diversified developer of innovative oncology surgical and diagnostic products, today announced that, following the presentation of full the data set from the NEO3-09 clinical trial of Lymphoseek at the American Society of Clinical Oncology (ASCO) Meeting yesterday in Chicago, two of the principal investigators in the trial participated with Company representatives in an event for analysts and institutional investors last evening following the poster session. Dr. Anne Wallace of the Moores Cancer Center, University of California San Diego, and Dr. Vernon Sondak of the H. Lee Moffitt Cancer Center presented their experience in the trials to the select group of analysts and institutional investors. Copies of the slides presented by Dr. Wallace, Dr. Sondak and the Company at the event, along with audio recordings of their presentations, are available to investors and interested parties at the Company’s website at www.neoprobe.com/ASCO2011.asp.

The NEO3-09 study, presented as a clinical poster and discussed Monday at the ASCO Meeting, reaffirmed superior Lymphoseek® (99mTc-tilmanocept) performance compared to vital blue dye in ILM procedures. The Company remains confident that the NEO3-09 study design, execution, regulatory input, statistical analyses and clinical study results for Lymphoseek are consistent with FDA and expert guidance and responsibilities to patient care. In particular, the Company’s approach has been built on the scientific method, with rigorous testing utilizing well-controlled clinical trials, the appropriate, on-label comparator, pre-specified endpoints, prospective statistical analysis plans, and consistent dialogue with regulatory authorities, to demonstrate the safe and effective performance of Lymphoseek.

“The design of both Phase 3 clinical trials, NEO3-05 and NEO3-09, have met the safety and efficacy expectations as discussed with FDA. Neoprobe has conducted the trials in accordance with the parameters discussed and reviewed with FDA. Direct comparison of Lymphoseek to vital blue dye – the only FDA-approved product for ILM procedures – is the appropriate comparator regulatory pathway to demonstrate the comparative clinical value of tilmanocept,” said George Mills, MD, former Director, Division of Medical Imaging and Radiopharmaceutical Drug Products at FDA and a Neoprobe consultant.

“We are confident the NDA package that will be filed with FDA will meet the standards of products that have an existing approved indication of use, said Fred Cope, Ph.D, Neoprobe’s Senior Vice President, Pharmaceutical Research and Clinical Development.”
