Heat Biologics Provides Second Quarter 2021 Business Update

​

Durham, NC – August 11, 2021 – Heat Biologics, Inc. (“Heat”) (NASDAQ: HTBX), a clinical-stage biopharmaceutical company focused on developing first-in-class therapies to modulate the immune system, today provided financial, clinical and operational updates for the second quarter ended June 30, 2021.

​

Jeff Wolf, Chief Executive Officer of Heat, commented, “This quarter we achieved several meaningful clinical, research and business milestones. First, we presented favorable survival data of HS-110 in previously treated non-small cell lung cancer (NSCLC) patients at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting. Based on these results, we believe HS-110, in combination with a checkpoint inhibitor (CPI), holds significant potential to improve survival benefit for patients with non-small cell lung cancer. We are continuing to evaluate possible Phase 3 registration pathways with the FDA and potential partners.  At the same time, we are exploring a variety of paths forward related to our infectious disease efforts.  We look forward to providing further near-term updates.”

​

“This quarter we also announced the groundbreaking for our biomanufacturing/bioanalytic facility in San Antonio, TX and the expansion of our current research and development (R&D) facilities at our corporate headquarters in Morrisville, NC. This expansion will support enhanced R&D capabilities including in-house synthesis and production of antibodies and other drugs/reagents, as well as an expanded vivarium for onsite pre-clinical studies. We believe that this expansion will allow us to accelerate R&D timelines and generate cost savings on research and development by bringing more of our development activities in-house.”

​

“Moreover, we have maintained a strong balance sheet with approximately $122.5 million of cash, cash equivalents and short-term investments which should allow us to augment our clinical programs as well as enhance and expand our therapeutic pipeline.”

Second Quarter 2021 Financial Results

●

Recognized $0.5 million of grant revenue for qualified expenditures under the CPRIT grant compared to $0.6 million for the quarter ended June 30, 2020. The decrease in grant revenue in the current-year period primarily reflects the expected timing of completion of deliveries under the current phase of the contracts. As of June 30, 2021, we had a grant receivable balance of $0.4 million for CPRIT proceeds not yet received but for which the costs had been incurred or the conditions of the award had been met. We continue our efforts to secure future non-dilutive grant funding to subsidize ongoing research and development costs.

●

Research and development expense was $4.2 million and $2.8 million for the three months ended June 30, 2021 and 2020, respectively.

●

General and administrative expense was $2.9 million and $1.8 million for the three months ended June 30, 2021 and 2020. The increase was primarily due to an increase in stock-based compensation expense.

●

Net loss attributable to Heat Biologics was approximately $6.5 million, or ($0.26) per basic and diluted share for the quarter ended June 30, 2021 compared to a net loss of approximately of $4.5 million, or ($0.35) per basic and diluted share for the quarter ended June 30, 2020.
