Pelican Therapeutics, a Subsidiary of Heat Biologics, Receives Second Tranche of its $15.2 Million CPRIT Grant Award

DURHAM, NC / ACCESSWIRE / October 30, 2017 / Heat Biologics, Inc. ("Heat") (NASDAQ: HTBX), a biopharmaceutical company developing drugs designed to activate a patient's immune system against cancer, announced that its subsidiary, Pelican Therapeutics, Inc. ("Pelican"), received the second tranche in the amount of $6.5 million of its $15.2 million Cancer Prevention and Research Institute of Texas (CPRIT) grant award. To-date, Pelican has received an aggregate of $8.3 million in grants from CPRIT.

The CPRIT award supports the pre-clinical development, manufacturing and clinical development of a 70-patient Phase 1 clinical trial for PTX-35, the company's lead asset. PTX-35 is a novel co-stimulatory monoclonal antibody against TNFRSF25, an emerging co-stimulatory receptor on T-cells. PTX-35, in combination with checkpoint inhibitors and other immunotherapy agents, has the potential to improve clinical responses for a broad range of patients by expanding the population of antigen-specific "memory" CD8+ T-cells - the immune cells critical in tumor eradication.

"We believe these funds will enable us to progress our manufacturing efforts and advance our pipeline, with the goal of addressing the unmet need for patients who don't respond well to current cancer therapy," said Rahul Jasuja, Ph.D., CEO of Pelican.

About Heat Biologics

Heat Biologics is a biopharmaceutical company developing immunotherapies designed to activate a patient's immune system against cancer by inducing CD8+ "Killer" T-cells. Our T-Cell Activation Platform (TCAP) produces therapies designed to turn "cold" tumors "hot," and be administered in combination with checkpoint inhibitor therapies and other immuno-modulators to increase their effectiveness. We are currently enrolling patients in our Phase 2 clinical trial for non-small cell lung cancer, in combination with Bristol-Myers Squibb's nivolumab (Opdivo®). We also have numerous pre-clinical programs at various stages of development. For more information, please visit www.heatbio.com.

About Pelican Therapeutics

Pelican Therapeutics, Inc., a subsidiary of Heat, is focused on the development of monoclonal antibody and fusion protein-based therapies designed to activate the immune system. PTX-35 targets the T-cell co-stimulator, TNFRSF25, and is designed to harness natural immune mechanisms that may reprogram tumor immunity. When combined with immunotherapies, including Heat's T-cell Activation Platform (TCAP), PTX-35 may have the ability to boost antigen-specific T-cells and eliminate tumor cells in patients. PTX-15, Pelican's second product candidate, is a human TL1A-lg fusion protein that mimics the natural ligand of TNFRSF25, and is designed to modulate T-cells that control the regulatory arm of the immune system.

In June 2016, Pelican was awarded a $15.2 million Cancer Prevention Institute of Texas (CPRIT) grant to support further development of PTX-35 and fund a Phase 1 clinical trial to examine potential benefits to patients with several types of cancers, such as lung, lymphoma, prostate, pancreatic and ovarian.
