Heat Biologics Reports First Quarter 2016 Financial Results

DURHAM, NC – May 11, 2016 – Heat Biologics, Inc. (“Heat”) (Nasdaq: HTBX), an immuno-oncology company developing novel therapies that activate a patient’s immune system against cancer, reported its financial results for the first quarter ended March 31, 2016.  

“We are focused on achieving near-term milestones to rebuild shareholder value.  Our primary goal is to advance HS-410 for the treatment of non-muscle invasive bladder cancer with one-year disease-free survival, immune response, safety and tolerability data expected in the fourth quarter of this year,” said Jeff Wolf, Heat’s Founder and CEO.  “In addition, we are looking forward to presenting new data at the upcoming ASCO Annual Meeting in June around our Phase 1b trial evaluating HS-110 in combination with an anti-PD-1 checkpoint inhibitor for the treatment of non-small cell lung cancer.”

Recent Developments & First Quarter 2016 Corporate Highlights

·

In May, Heat had an abstract accepted for poster presentation at the ASCO Annual Meeting being held on June 3-7, 2016 in Chicago, IL.  The poster is entitled “Broadening response rates to PD-1 therapy in advanced lung adenocarcinoma: Viagenpumatucel-L (HS-110) in combination with nivolumab in the ongoing DURGA trial” (Abstract #TPS9102).  Abstracts will be made available on the ASCO website at www.asco.org in line with the conference’s embargo policy.   

·

In April, Heat presented three posters at the AACR Annual Meeting.  In the poster entitled “Phase I/II Study of Patients with Non-Muscle Invasive Bladder Cancer (NMIBC) Treated with Vesigenurtacel-L (HS-410) with or without BCG,” Heat reported that no additional recurrences had been reported to-date, with all patients now at least 18 months out from enrollment.  In another poster, Heat reported initial preclinical results from its collaboration with OncoSec Medical Incorporated in which researchers concluded that combining Heat’s ComPACT vaccine with OncoSec’s intratumoral DNA electroporation delivery platform stimulated an expansion of neoantigen-specific CD8+ T cells, leading to a regression in both treated and untreated cancer lesions in two mouse studies.  In the third poster, Heat reported positive preclinical data on its next generation ComPACT platform technology, which combines a T cell priming vaccine and a T cell co-stimulator in a single product.

·

In April, Heat implemented cost-saving measures and a focused corporate strategy to achieve data readout, with its current cash on-hand, anticipated in the fourth quarter of 2016 for its lead Phase 2 program evaluating HS-410 for the treatment of NMIBC.  These cost-saving measures included a workforce reduction of approximately 22 percent of the company’s headcount.

·

In April, Heat appointed John Prendergast, Ph.D., to its Board of Directors.  

·

In March, Heat closed a public offering of approximately $6.8 million in gross proceeds, which will primarily be used to complete its Phase 2 clinical trial evaluating HS-410 for the treatment of NMIBC.  Remaining funds will be used to advance the current eight patients enrolled in our Phase 1b trial evaluating HS-110 in combination with nivolumab for the treatment of non-small cell lung cancer (NSCLC) through the reporting of topline data, as well as for licensing or acquisition of assets complementary to our existing programs and working capital and general corporate purposes.

·

In March, Heat presented additional preclinical data from its ComPACT platform technology at the Keystone Symposia on Cancer Vaccines.  Data presented demonstrated that ComPACT secreting OX40L generated the most potent immune response among other ComPACT co-stimulator variations including TL1A, 4-1BBL and ICOSL, as well as compared to systemic delivery of OX40 agonist antibody and vaccine alone.

·

In February, Heat announced that it will no longer enroll new patients in its Phase 2 monotherapy trial arm evaluating HS-410 alone for the treatment of NMIBC following the resolution of the standard of care BCG shortage and discussions with the U.S. FDA.  Heat anticipates reporting topline 6-month data from the 16 enrolled patients in the fourth quarter of 2016, contemporaneous with reporting data from Heat’s BCG combination cohorts.

·

In February, Heat announced that the U.S. FDA lifted the partial clinical hold on its HS-410 Phase 2 clinical trial and patient enrollment was resumed after less than one week; clinical timelines were materially unchanged. The partial clinical hold came after Heat concluded that the cell line on which HS-410 is based had been previously misidentified and immediately notified FDA of this conclusion. The FDA placed Heat’s HS-410 Phase 2 clinical trial on partial clinical hold while they reviewed updated documentation. The partial clinical hold did not relate to concerns regarding the safety or efficacy of HS-410.

·

In January, Heat reported three-month interim data from the unblinded, monotherapy arm in its Phase 2 trial evaluating HS-410 for the treatment of NMIBC.  Images of the bladder taken from several patients treated with HS-410 alone showed changes that resemble T cell-rich structures that Heat has observed in biopsy samples, indicating that systemic administration with HS-410 leads to a localized immune response within the bladder that cannot be attributed to standard of care.

First Quarter 2016 Financial Highlights

·

Research and development expenses decreased to approximately $500,000 in the first quarter of 2016 compared to approximately $504,000 in the first quarter of 2015, a decrease of approximately $4,000.  The decrease is attributable to reductions in patent, license and other professional fees offset by compensation costs associated with new hires, as well as supplies and facilities as we bring more capabilities in-house.

·

Clinical and regulatory expenses increased to approximately $3.2 million in the first quarter of 2016 compared to approximately $2.2 million in the first quarter of 2015, an increase of approximately $1.0 million.  The increase is attributable to clinical trial execution expenses, personnel costs and expenses related to the production of our clinical trial material.

·

General and administrative expenses decreased to approximately $1.0 million in the first quarter of 2016 compared to approximately $1.3 million in the first quarter of 2015, a decrease of approximately $0.3 million.  The decrease is attributable to non-cash stock compensation expense for non-employees associated with the company’s reduced shared price, as well as reduced professional services and third party expenses.

·

Net loss for the first quarter of 2016 was $4.7 million compared to a net loss of $4.0 million for the first quarter of 2015.

·

Cash, cash equivalents and short-term investments totaled approximately $11.8 million at March 31, 2016 compared to $11.6 million at December 31, 2015.  This includes the $6.1 million in net proceeds raised during our March 2016 public offering.

About Heat Biologics, Inc.

Heat Biologics, Inc. (NASDAQ: HTBX) is an immuno-oncology company developing novel therapies that activate a patient’s immune system against cancer.  Heat’s highly specific T cell-stimulating platform technologies, ImPACT and ComPACT, form the basis of its product candidates.  These platforms, in combination with other therapies, such as checkpoint inhibitors, are designed to address three distinct but synergistic mechanisms of action: robust activation of CD8+ “killer” T cells (one of the human immune system’s most potent weapons against cancer); reversal of tumor-induced immune suppression; and T cell co-stimulation to further enhance patients’ immune response.  Currently, Heat is conducting a Phase 2 trial with its HS-410 (vesigenurtacel-L) in patients with non-muscle invasive bladder cancer (NMIBC) and a Phase 1b trial with its HS-110 (viagenpumatucel-L) in combination with an anti-PD-1 checkpoint inhibitor to treat patients with non-small cell lung cancer (NSCLC).  For more information, please visit www.heatbio.com.
