Heat Biologics to Present New Data on Its ComPACT Platform at the CRI-CIMT-EATI-AACR Inaugural International Cancer Immunotherapy Conference

DURHAM, N.C., Sept. 16, 2015 (GLOBE NEWSWIRE) -- Heat Biologics, Inc. ("Heat"), (Nasdaq:HTBX), a clinical stage cancer immunotherapy company, announced that it will present a poster titled "Locally Secreted Fc-OX40L is Superior to Systemic, Antibody Mediated, OX40 Co-Stimulation for Combination Immunotherapy" at the International Cancer Immunotherapy Conference. Heat's poster highlights further findings from the preclinical research conducted with ComPACT, the company's next-generation combination immunotherapy platform. The poster (#B006) will be presented in the Empire Ballroom at the Sheraton Times Square Hotel in New York City from 4:45 p.m. to 6:45 p.m. on Friday, September 18, 2015.  

"We are excited to present additional preclinical data from our ComPACT platform demonstrating that vaccination and co-stimulation can be achieved with a single cell-based product. This may simplify clinical development by enhancing the activation of tumor-antigen specific CD8+ T cells, a potent immune response component believed to be instrumental in treating cancer," stated Taylor Schreiber, MD, Ph.D., Chief Scientific Officer.   

ComPACT combines a pan-antigen T cell priming vaccine and T cell co-stimulator in a single product, offering the potential benefits of combination immunotherapy in a single drug without the need for multiple independent biologic products. ComPACT has been engineered to incorporate various fusion proteins targeting co-stimulatory receptors (OX40, ICOS, 4-1BB), enabling the combination of two important immunotherapy pathways in a single drug. 

Heat expects to announce its selection of the first product candidate based on the ComPACT platform in the first quarter of 2016. 

The International Cancer Immunotherapy Conference will cover all areas of inquiry in cancer immunology and immunotherapy, and is jointly sponsored by the Cancer Research Institute (CRI), the Association for Cancer Immunotherapy (CIMT), the European Academy of Tumor Immunology (EATI) and the American Association for Cancer Research (AACR).
