Pieris Pharmaceuticals Reports Financial Results f

BOSTON, MA --(Marketwired - November 08, 2017) - Pieris Pharmaceuticals, Inc. ( NASDAQ : PIRS ), a clinical-stage biotechnology company advancing novel biotherapeutics through its proprietary Anticalin ^® technology platform for cancer, respiratory and other diseases, today reported financial results for the third quarter of 2017 and provided a corporate update:

• PRS-343: During the third quarter, the Company initiated enrollment of a Phase I study for PRS-343, a 4-1BB/HER2 bispecific, its lead proprietary, immuno-oncology drug candidate. The trial is a multi-center, open-label, Phase I dose escalation study in HER2-positive patients that will include expansion cohorts.
• PRS-060: The Company is on track to initiate a first-in-human clinical study for PRS-060, an IL-4 receptor alpha antagonist, by year end. The Company is the Phase 1 clinical trial sponsor for PRS-060, which is partnered with AstraZeneca as part of a respiratory alliance signed in May 2017, with AstraZeneca funding the cost of this study. Dosing of the first subject will trigger a milestone payment of $12.5 million by AstraZeneca to Pieris.
• PRS-080: The Company initiated enrollment in a Phase IIa study for PRS-080, a hepcidin antagonist, in dialysis-dependent patients with functional iron deficient (FID) anemia. The study is being conducted in a randomized, placebo-controlled manner with two dose cohorts of 4 mg per kg and 8 mg per kg body weight, with 4 patients receiving drug at each dose level and 2 patients on placebo within each cohort.

"During the third quarter, we continued to execute on our pipeline and actively engage with strategic partners, with the advancement of our lead immuno-oncology drug candidate PRS-343 into the clinic and continued progression of lead assets under our alliances with AstraZeneca and Servier in respiratory disease and immuno-oncology," said Stephen S. Yoder, President and CEO of Pieris. "PRS-343 marks the first 4-1BB-based bispecific to reach clinical development, a significant milestone for our Company and a demonstration of our leadership in T-cell costimulatory receptor biology. In addition, we expect to initiate the PRS-060 first-in-human study during the fourth quarter of this year, which would result in advancing three compounds in various stages of clinical development during 2017. I am very proud of the diligent efforts of our employees in Munich and Boston to have made this possible. Next year, we look forward to sharing data from our clinical studies and updating investors on additional program selections within our growing proprietary pipeline and strategic alliances."

Third Quarter Financial Update:

Cash Position - Cash and equivalents totaled $89.9 million as of September 30, 2017, compared to $29.4 million as of December 31, 2016. The increase in cash was driven primarily by a $45.0 million upfront payment received as part of the AstraZeneca respiratory alliance, a EUR30.0 million (approximately $32.0 million) upfront payment received from Servier and a $2.8 million option payment received from ASKA. This was offset by $29.0 million of operating cash expenditures during the first nine months of the year.

R&D Expense - Research and Development expenses were $6.3 million and $17.0 million for the three and nine-month periods ending September 30, 2017, respectively, as compared to $4.6 million and $12.8 million for the three and nine-month periods ended September 30, 2016. The Company's increase in research and development expenses reflects advancement across its pipeline of programs as well as preparation for and advancement of clinical activities.

G&A Expense - General and administrative expenses were $2.9 million and $11.2 million for the three and nine-month periods ended September 30, 2017, respectively, as compared to $2.3 million and $6.7 million for the three and nine-month periods ended September 30, 2016. The increase in the 2017 periods as compared to the corresponding periods in 2016 is largely attributable to $1.8 million in transaction fees for the successful close of our license and collaboration agreement with AstraZeneca. Recruiting and personnel related costs are increasing as we continue to build the organization and require an increasing amount of outside professional services, including for intellectual property and corporate legal work, auditing, finance, communications and in other facets of the business.

Net Loss - Net loss was $7.1 million or ($0.16) per share for the three-month period ended September 30, 2017, compared to a net loss $6.2 million or ($0.14) per share for the three-month period ended September 30, 2016. Net loss was $25.1 million or ($0.58) per share for the nine-month period ended September 30, 2017, compared to a net loss $16.2 million or ($0.39) per share for the nine-month period ended September 30, 2016.
