Heat Biologics Presents Positive ComPACT Preclinical Data at the Keystone Symposia

DURHAM, N.C., March 07, 2016 -- Heat Biologics, Inc. (“Heat”) (Nasdaq:HTBX), an immuno-oncology company developing novel therapies that activate a patient’s immune system against cancer, announced that positive preclinical data from its next generation ComPACT platform technology, which combines a T cell priming vaccine and T cell co-stimulator in a single product, were presented as both an oral presentation and poster at the Keystone Symposia  on Cancer Vaccines: Targeting Cancer Genes for Immunotherapy, held in Whistler, British Columbia, Canada on March 6-10, 2016.  Data presented showed 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.

A copy of the poster entitled “Combination Immunotherapy: T cell costimulation (OX40L, TL1A, 4-1BBL and ICOSL) secreted locally by Gp96-Ig vaccines elicits robust antigen-specific memory T cell responses and tumor elimination” will be made available in the Publications section of Heat’s corporate website. 

About ComPACT

Currently in preclinical development, ComPACT represents a potential dual-acting immunotherapy, combining a pan-antigen T cell priming vaccine and a T cell co-stimulator in a single product.  Heat has developed its first ComPACT product candidate, HS-120, as a potential treatment for non-small cell lung cancer (NSCLC) and anticipates filing an Investigational New Drug (IND) application by the end of 2016.

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.
