On October 10, 2012, Navidea Biopharmaceuticals, Inc. (the "Company") issued a press release announcing that it had posted an update on the status of the LymphoseekŪ (technetium Tc 99m tilmanocept) Injection ("Lymphoseek") new drug application ("NDA") review on the Company's website. The update stated that, as part of its continuing effort to secure regulatory NDA approval for Lymphoseek, a Type A meeting with the United States Food and Drug Administration ("FDA") had been scheduled to advance the Company's planned response to the FDA regarding deficiencies in current Good Manufacturing Practice ("cGMP") identified during inspections at third-party manufacturing facilities.

The Company has now successfully completed the Type A meeting with the FDA and has received clarifying guidance from the Agency in regard to the cGMP issues noted in the FDA's Complete Response Letter ("CRL") received on September 10, 2012, and the requirements for the Company's response to the CRL for the Lymphoseek NDA. The meeting confirmed that the scope of the Company's resubmission will be focused on the previously noted cGMP manufacturing deficiencies observed at third-party manufacturing facilities. The meeting further affirmed the requirements that the Company must address in its resubmission.

A copy of the complete text of the Company's October 10, 2012, press release, and the referenced update on the status of the Lymphoseek NDA, are attached as Exhibit 99.1 and 99.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
