Heat Biologics Provides Year-End Business Update

Provides update on development of gp96 vaccine for preventing infection from the SARS-CoV-2 coronavirus that causes COVID-19

Reports progress on development of COVID-19 30-minute point of care diagnostic test

Completed enrollment in Phase 2 non-small cell lung cancer trial

Reports over $25 million of cash and short-term investments as of March 23, 2020

DURHAM, NC / ACCESSWIRE / March 30, 2020 /Heat Biologics, Inc. ("Heat")(NASDAQ:HTBX), a clinical-stage biopharmaceutical company specialized in the development of novel therapeutic and prophylactic vaccines, including one for coronavirus COVID-19, today provided financial, clinical and operational updates for the year ended December 31, 2019.

Jeff Wolf, Chief Executive Officer of Heat Biologics, commented, "2019 was an exciting year for Heat, as we advanced our therapeutic pipeline. This past November, we presented additional positive top line Phase 2 data of HS-110 plus BMS checkpoint inhibitor nivolumab (Opdivo®) in advanced NSCLC lung cancer patients at the American Association for Cancer Research (AACR) Special Conference on Tumor Immunology and Immunotherapy. We are highly encouraged by the data as we advance partnership and collaboration discussions. Earlier this year, we announced dosing the first patient in a Phase 1 clinical trial of our co-stimulatory HS-130, in combination with HS-110, for patients with advanced solid tumors refractory to standard of care, which marks a key milestone for Heat."

"We recently announced plans to develop a vaccine for preventing infection from the SARS-CoV-2 coronavirus that causes COVID-19 utilizing our robust gp-96 vaccine platform in collaboration with the University of Miami. Heat's gp96 platform has undergone rigorous testing as a vaccine against SIV/HIV, malaria, zika and other infectious diseases in numerous National Institutes of Health (NIH) and Department of Defense (DOD)-funded mice and primate trials and has been tested in over 300 patients in multiple NIH and Heat-funded oncology trials. We believe this platform has the potential to provide broad protection against COVID-19, and possible future mutations of COVID-19 or other coronaviruses. We are encouraged by the prospects for this program and are moving forward with our partners to advance this vaccine as quickly as possible."

"Earlier this month we also announced a collaboration with the University of Miami to develop a proprietary COVID-19 point-of-care diagnostic test. The new paper-based test is being designed to provide a read-out in a fraction of the time required for most other tests, have no technical hardware requirements, have low cost of goods, be easily manufactured at scale, and provide binary readout if the patient is positive for a disease within 30 minutes. Unfortunately, current diagnostic tests, are in short supply and often take days for results. This diagnostic is being designed for early detection to provide critical and time-sensitive information to help curb the spread of the disease."

Mr. Wolf concluded, "We share our sympathies to those individuals and families impacted by COVID-19 and are committed to helping find solutions to this global pandemic. I'd like to thank all of the Heat and University of Miami professionals that have worked tirelessly to advance our therapeutic and diagnostic platforms. Importantly, we have over $25 million of cash and short-term investments as of March 23, 2020, which should put us on a solid financial footing as we advance our programs. Moreover, we believe that upcoming catalysts and milestones have the potential to drive significant shareholder value."
