Navidea Biopharmaceuticals Receives FDA Feedback Regarding Rheumatoid Arthritis Clinical Trial Design and Provides Business Updates

DUBLIN, Ohio--(BUSINESS WIRE)--

Company Will Host Conference Call at 5:00 p.m. (ET) on Monday, April 8, 2019

Navidea Biopharmaceuticals, Inc. (NYSE American: NAVB) (“Navidea” or the “Company”), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced that it received feedback from the U.S Food and Drug Administration (“FDA”) regarding the Company’s planned clinical studies that will evaluate joint disease in patients with Rheumatoid Arthritis (“RA”) and monitor patient response to therapy.

Clinical Studies in Rheumatoid Arthritis

The Company’s proposed RA studies were discussed with the FDA during an in-person meeting, and through follow-up collaborative efforts. The FDA has communicated that the first study, a Phase 2b trial, is aligned with expectations for the studies and that they will continue to work with Navidea as we progress into Phase 3 clinical trials. The Company is now prepared to initiate this study, NAV3-31 (Evaluation of the Precision and Sensitivity of Tilmanocept Uptake Value (“TUV”) on Tc99m Tilmanocept Planar Imaging). This study will also provide confirmatory support necessary to initiate Navidea’s Phase 3 study program which was also presented to the FDA. The pivotal Phase 3 study program will assess joint disease status and monitor patient response to therapy.

Dr. Michael Rosol, Chief Medical Officer of Navidea, said, “We are delighted to have received the news from the FDA that we are progressing in the right direction with our upcoming Phase 2b study. This study is designed to enable us to establish objective, quantifiable Tc99m tilmanocept imaging metrics of the joints of healthy subjects and patients with active RA. The robust establishment of the range of TUVs from healthy subjects and RA patients is a critical step to set us up for the greater validation of our imaging readout as an early biomarker of patient response to therapy, method for longitudinal monitoring of treatment, and potentially for RA pathobiology subtype discrimination. Our entire clinical team has been pushing hard in preparation and this important trial is set to begin in the near future. We plan to proceed with our timelines and will ensure we remain in line with FDA requirements.”

Bonnie Abbruzzese, Navidea’s Senior Director of Clinical Development, stated, “We have identified our clinical trial study centers and have received Investigational Review Board approval for the NAV3-31 image stability and outcome trial, which will generate data to guide the development of the pivotal Phase 3 trial. Our investigators are eager to begin enrolling into the NAV3-31 protocol and we expect to inject the first subject this quarter.”

Bill Regan, Chief Compliance Officer of Navidea, said, “As we work towards full development of the RA program it is extremely important to work collaboratively with the FDA to ensure continued alignment with FDA expectations in order to achieve the Navidea goal of a successful Phase 3 program to develop the premiere diagnostic agent for patients with RA. Input from the FDA up to this point has been very beneficial and we look forward to continued collaboration as we progress through the complete development program.”

Jed Latkin, Navidea’s Chief Executive Officer, commented, “This is an important step along the path to approval of our RA diagnostic product candidate and represents Navidea’s continued dedication to the execution of our goals and to enhance value for stockholders. We will continue to work with the FDA as data from NAV3-31 becomes available. We will also continue to be transparent with the market and give updates to our stockholders and all interested parties, as appropriate.”

RA is a chronic disease affecting over 1.3 million Americans and as much as one percent of the worldwide population.1 Tc99m Tilmanocept may enable, for the first time, objective visualization and direct quantification of RA disease activity and evaluation of joint-specific inflammation. If the product is successfully developed, Navidea would expect to play a major role in the management of RA patients worldwide.

Receipt of NYSE American Deficiency Letter

Navidea also announced today that it received a notification (the “NYSE Letter”) from the NYSE American LLC (the “NYSE American”) stating that Navidea was not in compliance with Section 1003(a)(i) of the NYSE American Company Guide, which requires an issuer to have stockholders’ equity of $2.0 million or more if it has reported losses from continuing operations and/or net losses in two of its three most recent fiscal years. The NYSE Letter noted that Navidea’s most recent Form 10-K reported stockholders’ equity of $1.7 million as of December 31, 2018, and that Navidea has reported losses from continuing operations and/or net losses in its five most recent fiscal years ended December 31, 2018.

Navidea previously disclosed, among other things, that it received a notification from the NYSE American stating that Navidea was not in compliance with Section 1003(f)(v) of the NYSE American Company Guide, which relates to the selling price per share of the Company’s securities. The NYSE American staff initially granted Navidea a plan period through February 14, 2019 to regain compliance with Section 1003(f)(v) by effecting a reverse stock split or otherwise demonstrating sustained price improvement. In January 2019, the NYSE American granted the Company an extension until March 31, 2019 to regain compliance with Section 1003(f)(v) of the NYSE American’s continued listing standards, and on March 22, 2019 Navidea announced that it was in discussions with the NYSE American regarding the timing of a potential reverse stock split later than March 31, 2019. The NYSE Letter advised that the Company must provide the NYSE American with a plan to regain compliance with the price standard by April 15, 2019 in order to be considered for continued trading through its equity plan period end date of February 14, 2020, subject to periodic review of progress consistent with the equity plan.

In August 2018, Navidea’s stockholders voted to approve a potential amendment to the Company’s amended and restated certificate of incorporation to effect a reverse split of the Company’s common stock, as determined by the Board of Directors at its discretion, of a ratio of not less than one-for-five and not more than one-for-twenty. In addition to the goal to regain compliance of the listing standards, the Company believes that if the reverse split is effected, a higher share price may attract additional brokerage firms and institutional investors who previously may have been prohibited from investing in shares of the Company.

Navidea’s Common Stock will continue to be listed on the NYSE American while it attempts to regain compliance with the listing standards noted, subject to Navidea’s compliance with other continued listing requirements.
