Item 7.01. – Regulation FD Disclosure.

On February 25, 2016, Heat Biologics, Inc. (the “Company”) issued a press release announcing the matters discussed in Item 8.01 of this Current Report on Form 8-K. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference. Exhibit 99.1 shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Item 8.01. – Other Events.

The Company today announced that it will no longer enroll new patients in its Phase 2 monotherapy trial arm evaluating HS-410 alone for the treatment of non-muscle invasive bladder cancer (“NMIBC”).  The Company added the monotherapy trial arm in response to the intermittent global shortage of standard of care Bacillus Calmette-Guérin (BCG) in early 2015.  The shortage has since then been resolved and as such, the Company will no longer enroll  new patients in this trial arm based on discussions with the U.S. Food and Drug Administration.  The decision does not relate to concerns regarding the safety profile of HS-410.  The 16 patients currently enrolled, out of the anticipated 25 patients, can continue receiving HS-410 monotherapy per the study protocol.  The Company anticipates reporting topline 6-month data from these 16 patients in the fourth quarter of 2016, contemporaneous with reporting data from the Company’s BCG combination cohorts.

This decision does not impact the Company’s three additional randomized Phase 2 trial arms evaluating HS-410 in combination with BCG for the treatment of NMIBC.  As previously announced, the Company completed enrollment of the 75 patients for these three combination trial arms in October 2015 and continues to expect to report one-year topline efficacy, immune-response and safety data in the fourth quarter of 2016.
