DURHAM, N.C., Feb. 17, 2017 (GLOBE NEWSWIRE) -- Heat Biologics, Inc. (“Heat”) (Nasdaq:HTBX), announced that it presented a poster of its immunological data from its 94-patient Phase 2 trial evaluating vesigenurtacel-L (HS-410) either alone or in combination with BCG in patients with non-muscle invasive bladder cancer (NMIBC) at the 2017 Genitourinary (GU) Cancers Symposium.  Researchers reported that HS-410, in combination with BCG, continues to be generally well-tolerated, that HS-410 activates CD8+ T cells and that these immune responders appear to have a lower recurrence rate than non-immune responders. Taken together, these data strengthen support for the vaccine mechanism of action and clinical proof-of-concept of immune activation.

Patients were also evaluated based on their levels of tumor infiltrating lymphocytes (TIL) at the start of treatment.  In the placebo arm, patients with low TIL levels at baseline had a higher incidence of disease recurrence than patients with high TIL levels at baseline.  However, in the vaccine-treated group, recurrence levels were essentially the same between the high and low TIL subgroups, at 25% and 29%, respectively.  The fact that these two groups of patients saw clinical outcomes that were roughly identical may warrant further evaluation.

“These data continue to support our hypothesized vaccine mechanism of action,” said Jeff Hutchins, Ph.D., Heat’s Chief Scientific Officer and Senior Vice President of Preclinical Development. “Furthermore, we believe this vaccine treatment strategy could be evaluated in more advanced bladder patient populations, where immunotherapy has been shown to be effective, but where not all patients respond to therapy, likely due to insufficient T cell activation and proliferation.”

As previously reported, vaccine arms did not show a statistical improvement over the placebo arm in the primary endpoint (1-year recurrence free survival). However, in keeping with clinical trial guidance, Heat continues to monitor all patients enrolled in the study for a 2-year duration.

The poster will be uploaded to the publications section of Heat’s corporate website in line with the conference’s embargo policy.

About Heat Biologics, Inc.
Heat Biologics, Inc. (Nasdaq:HTBX) is an immuno-oncology company developing novel therapies that are designed to activate a patient’s immune system against cancer utilizing an engineered form of gp96, a protein that activates the immune system when cells die. Heat’s highly specific T cell-stimulating therapeutic vaccine 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 1b trial with HS-110 (viagenpumatucel-L) in combination with an anti-PD-1 checkpoint inhibitor to treat patients with non-small cell lung cancer (NSCLC) and a Phase 2 trial with HS-410 (vesigenurtacel-L) in patients with non-muscle invasive bladder cancer (NMIBC).

Heat’s wholly-owned subsidiary, Zolovax, Inc., is developing therapeutic and preventative vaccines to treat infectious diseases based on Heat’s gp96 vaccine technology, with a current focus on the development of a Zika vaccine in conjunction with the University of Miami.
