Heat Biologics Reports First Quarter 2018 Results
and Provides Corporate Update

DURHAM, NC – May 15, 2018 – Heat Biologics, Inc. (Nasdaq: HTBX), a biopharmaceutical company developing drugs designed to activate a patient’s immune system against cancer, today reported financial and clinical updates for the first quarter ended March 31, 2018.

“We had an eventful first quarter, with a number of positive clinical developments,” said Jeff Wolf, CEO of Heat. “Most notably, we announced positive interim results from our Phase 2 study investigating HS-110 in combination with Bristol-Myers Squibb’s anti-PD-1 checkpoint inhibitor, nivolumab (Opdivo®), in patients with advanced non-small cell lung cancer (NSCLC) whose cancers had progressed after treatment with one or more lines of therapy.  These data are especially encouraging in patients with low levels of TIL and PD-L1, who are among the most difficult-to-treat patients.  Importantly, we believe the data are consistent with the mechanism of action of our T-cell Activation Platform, which has been shown to promote a robust T-cell immune response.  We believe the ability of our platform to convert “cold tumors” to “hot tumors” will be an important component in effective immunotherapy combinations against cancer.”

“Given the strength of our recent data, we recently completed a capital raise for gross proceeds of $20.7 million. Consequently, Heat should have sufficient capital to accomplish the following key objectives over the next 5 quarters: 1) complete enrollment in our Phase 2 trial for HS-110 in NSCLC, 2) begin patient enrollment for our ComPact™ platform, 3) undertake our Phase I study with our first-in-class T cell costimulator antibody, PTX-35, and 4) report preliminary data for each of these trials.”

Research and development expenses increased to $2.9 million for the quarter ended March 31, 2018 compared to $1.8 million for the quarter ended March 31, 2017. The $1.1 million increase is due to an increase in CMC activity in our HS-110 and PTX-35 programs as well as continued patient enrollment as we progress in our phase 2 HS-110 clinical trial.

General and administrative expense increased approximately 20% to $1.8 million for the quarter ended March 31, 2018 compared to $1.5 million for the quarter ended March 31, 2017.
