“We continued to make advances and generate new data from our novel immunotherapy programs this quarter. Of particular note, we unveiled ComPACT, a next generation combination immunotherapy platform that holds the promise of delivering T-Cell priming and co-stimulatory molecules in a single biological product,” said Jeff Wolf, Heat’s CEO.  “We also announced a new Phase 1b trial of HS-110 in non-small cell lung cancer which will explore the combination of HS-110 with various immune modulators.”

“We expect a number of important value creating milestones in the second half of 2015,” continued Mr. Wolf.  “For HS-410, our immunotherapy candidate for non-muscle-invasive bladder cancer, we plan to release one-year safety and immune response data from our Phase 1 trial and complete enrollment in our Phase 2 trial.  Our accomplishments this quarter and throughout the year position us well to achieve our goals in the second half of 2015 and beyond.”

Quarter Ended June 30, 2015 vs. Quarter Ended June 30, 2014

Research and development expenses for the second quarter of 2015 decreased 31% to $0.6 million, compared to the $0.8 million in the second quarter of 2014.  The decrease is attributable to a decrease in pre-manufacturing costs associated with preparing to produce vaccines for use in our clinical trials, offset by increases in lab supplies and other fees.

Clinical and regulatory expenses increased to $3.4 million, compared to $1.1 million for the second quarter of 2014. The increase was attributable to increases in clinical trial execution costs, increases in investigator payments, as well as an increase in costs related to the production of vaccines for our clinical trials.

General and administrative expenses for the quarter were $0.9 million, compared to $1.0 million for the second quarter of 2014. The decrease is attributable to a decrease in personnel expense, a decrease in facility expense due to allocation to other departments, and a decrease in travel expenses.

Net loss attributable to Heat Biologics, Inc. in the second quarter was $4.7 million, or ($0.56) per basic and diluted share.  This compares to a net loss of $2.8 million, or ($0.44) per basic and diluted share in the second quarter of 2014.  

As of June 30, 2015, the Company had cash, cash equivalents, and short-term investments of approximately $19.3 million.  This compares to cash, cash equivalents, and short-term investments of approximately $14.4 million at December 31, 2014.

Six Months Ended June 30, 2015 vs. Six Months Ended June 30, 2014

Research and development expenses for the six months ended June 30, 2015 (2015 Period) decreased to $1.1 million, compared to $1.4 million for the six months ended June 30, 2014 (2014 Period).  The decrease from the 2014 Period to the 2015 Period is attributable to a decrease in pre-manufacturing costs associated with preparing to produce vaccines for use in our clinical trials, as well as decreases in patent, license and other professional fees, offset by increases in compensation costs associated with new hires, lab supplies and other costs, and depreciation related to the build out of the lab facility and other associated costs.  

Clinical and regulatory expenses increased to $5.5 million, from $2.0 million in the first six months of 2014. The increase year over year is attributable to increases in clinical trial execution costs, increased investigator payments, as well as an increase in costs related to the production of vaccines for our clinical trials. Additionally, personnel cost, including consultants, professional fees, facilities costs, travel, and license fees increased.

General and administrative costs increased to $2.2 million, from $2.0 million in the comparable period in 2014.  The increase is attributable to increase in pay to certain key employees, an increase in professional services such as accountants, attorneys and investor relations, and travel. These increases are offset by a decrease in facility and related costs as well as a decrease in depreciation.
