Announces Abstract Summarizing Favorable Interim Phase 2 Data of HS-110 Plus Nivolumab
Additional Data to be Reported in Poster Presentation at the SITC 34th Annual Meeting on November 8, 2019
DURHAM, NC / ACCESSWIRE / November 5, 2019 / Heat Biologics, Inc. (HTBX), a biopharmaceutical company developing immunotherapies designed to activate a patient's immune system against cancer, today announced that an abstract has been posted on The Society for Immunotherapy of Cancer's (SITC) website in connection with the Company's planned poster presentation at SITC's 34th Annual Meeting on November 8, 2019.
The abstract summarizes the latest interim top line data from Cohort B of the Company's Phase 2 trial of the Company's "off-the-shelf" cell-based therapy, HS-110, in combination with Opdivo® (Nivolumab) in advanced non-small cell lung cancer (NSCLC), which completed enrollment in July 2019. This cohort enrolled patients who had previously received a checkpoint inhibitor (CPI) and whose disease had subsequently progressed. The data suggests that re-challenging the immune system with nivolumab and HS-110 after checkpoint inhibitor treatment failure may restore responsiveness and clinical benefit. Additionally, the combination of HS-110 and nivolumab is well-tolerated, and no increase in the incidence of immune-related adverse events was observed to date, as compared to CPI monotherapy.

Jeff Wolf, Heat Biologics' CEO, commented, "NSCLC patients who progressed after checkpoint inhibitor treatment have limited therapeutic options. The latest results are encouraging and suggest that HS-110 in combination with nivolumab may address this key unmet medical need. As of this data cut, the median overall survival (OS) is estimated to be 11.8 months, with 70% of the patients still alive. I am unaware of any published checkpoint combination studies that offered superior OS in patients that had experienced previous checkpoint inhibitor treatment failure in NSCLC. This data also compares favorably to reported studies using chemotherapy following checkpoint inhibitor progression 1, 2 ".
Signals of clinical efficacy were observed in the reported objective response rate (ORR), disease control rate (DCR) and progression free survival (PFS). Importantly, patients experiencing dermal injection site reactions (ISR) had statistically significant improvement in PFS and OS compared to those without ISR (Hazard Ratio = 0.40, p=0.0068 and Hazard Ratio = 0.16, p=0.0005, respectively). Additional data will be presented at SITC on November 8 ,2019.

About Heat Biologics, Inc.
Heat Biologics is a biopharmaceutical company developing immunotherapies designed to activate a patient's immune system against cancer using CD8+ "Killer" T-cells. HS-110 is the Company's first biologic product candidate in a series of proprietary immunotherapies designed to stimulate a patient's own T-cells to attack cancer. Heat has completed enrollment in its Phase 2 clinical trial for advanced non-small cell lung cancer, in combination with Bristol-Myers Squibb's nivolumab (Opdivo®) or with Merck's pembrolizumab (Keytruda®). Pelican Therapeutics, a subsidiary of Heat, is focused on the development of co-stimulatory monoclonal antibody and fusion protein-based therapies designed to activate the immune system.
