Heat Biologics Provides Second Quarter 2020 Business Update

Progress on COVID-19 Vaccine Program

Reports over $100 million in cash and
short-term investments as of August 6, 2020

​

Durham, NC – August 7, 2020 – Heat Biologics, Inc. (“Heat”) (NASDAQ: HTBX), a clinical-stage biopharmaceutical company focused on developing first-in-class therapies to modulate the immune system, including multiple oncology product candidates and a novel COVID-19 vaccine, today provided financial, clinical and operational updates for the second quarter ended June 30, 2020.

​

Jeff Wolf, Chief Executive Officer of Heat Biologics, commented, "This quarter we achieved significant milestones in advancing our unique COVID-19 vaccine program, which we are developing in collaboration with researchers at University of Miami. Specifically, our latest pre-clinical studies demonstrated immunogenicity proof-of-concept, validating that the selected vaccine antigen may be appropriate for human testing. Preclinical testing demonstrated expansion of antibody-supporting CD4+, and virus killing CD8+ T-cells in the lungs of the animals, a major site for COVID-19 infection. We believe this platform may play an important role as a standalone vaccine or in combination with other antibody-generating vaccines to provide broad cellular T-cell and humoral protection against COVID-19, particularly for elderly patients and those with underlying health conditions who have an increased risk of complications and death from COVID-19.”

​

"Additionally, we established a partnership with Waisman Biomanufacturing to manufacture our COVID-19 vaccine for anticipated Phase 1 trials in humans. We believe that the unique capabilities and previous expertise gained working with Waisman on our cancer programs, HS-110 and HS-130 that are based upon the same gp96 platform, will help shorten the development timeline for our COVID-19 vaccine."

​

“We recently presented our latest data for HS-110 in combination with Nivolumab in our Phase 2 lung cancer trial at the 2020 American Society of Clinical Oncology (ASCO) Annual Meeting.  Importantly, this data demonstrated a strong survival benefit in a cohort of previously treated checkpoint inhibitor (CPI) naïve patients with advanced non-small cell lung cancer (NSCLC) and further reinforced the potential utility of HS-110 in combination with a checkpoint inhibitor as a frontline treatment for NSCLC.”

​

"We also continue to accelerate PTX-35, our potential first-in-class T-cell co-stimulatory antibody, through clinical development. Specifically, we announced patient enrollment in our first-in-human clinical trial in multiple solid tumors following FDA clearance of our Investigational New Drug (IND) application. This study is expected to enroll up to 30 patients with advanced solid tumors refractory to standard of care.”

​

“We have continued to strengthen our balance sheet, and now have over $100 million in cash and short-term investments as of August 6, 2020, which should provide us with the resources to significantly advance our clinical programs," concluded Mr. Wolf.
