NEOPROBE RECEIVES POSITIVE RESPONSE TO EUROPEAN RIGS SUBMISSION
All Scientific Advice Questions Provided with Affirmative Answers

DUBLIN, OHIO — October 31, 2008 — Neoprobe Corporation (OTCBB: NEOP), a diversified developer of innovative oncology and cardiovascular surgical and diagnostic products, today announced that the centralized European Medicines Agency (“EMEA”) has provided positive formal responses to Neoprobe’s scientific advice submission regarding RIGScan CR and the pathway to receive a marketing authorization for the drug.

Neoprobe asked the EMEA to review its manufacturing and clinical development plan for RIGScan CR. The EMEA concurred that Neoprobe could use updated and improved manufacturing processes to produce the antibody that is used in RIGScan CR and would be able to use all previously produced drug safety data derived from prior clinical studies to support a marketing authorization. The EMEA reviewed and agreed to the design and adequacy of a Phase 3 clinical study to be conducted in 380 patients with diagnosed primary or metastatic/recurrent colorectal cancer. The Phase 3 study would be a randomized trial with equal control and RIGScan CR treatment cohorts. The primary endpoint of the study would be improved survival for the RIGScan CR treated patients as compared to the control arm.

Improved survival for the RIGScan CR treated patients was demonstrated in a retrospective survival analysis of patients in a prior RIGScan CR clinical study (NEO2-14) that was accepted by the EMEA. In addition, the EMEA agreed to the clinical need for a product like RIGScan CR to improve the treatment of patients with colorectal cancer. Finally, the EMEA provided Neoprobe the opportunity to request a conditional marketing authorization (CMA) after completion of the initial antibody production or prospective clinical activities. The opportunity for granting a CMA will be dependent upon the review of the supportive manufacturing and/or clinical information and there can be no assurance that a CMA request would receive a favorable response.

David Bupp, Neoprobe’s President and CEO, said, “We are excited by the response from the EMEA. The scientific advice response provides a clear, achievable development pathway for RIGScan CR. The response acknowledges that the technology meets a currently unmet medical need and has the potential for improving the long term prognosis for both primary and recurrent colorectal patients. The EMEA has suggested a mechanism for an early termination of the study if, as anticipated, early improved outcomes are observed in the RIGScan treatment arm versus the control arm patients.”

Mr. Bupp, and Vice President and CFO, Brent Larson, will provide an update on Lymphoseek and RIGScan CR, as well as discuss the company’s results for the third quarter of 2008 during a conference call scheduled for 11:00 AM ET, Thursday, November 6, 2008.
