Pieris Pharmaceuticals Reports Full-Year 2016 Financial Results and Corporate Update

BOSTON, MA--(Marketwired - March 22, 2017) - Pieris Pharmaceuticals, Inc. (PIRS), a clinical-stage biotechnology company advancing novel biotherapeutics through its proprietary Anticalin® technology platform for cancer and other diseases, today reported financial results for the fourth quarter and fiscal year of 2016 and provided an update on the Company's recent developments.

"2016 was a highly productive year for Pieris marked by: i) broad advancement of our proprietary clinical and preclinical programs, ii) completion of a $16.5 million private placement financing that strengthened our shareholder base, iii) achievement of several milestones in our collaborative programs, and iv) expansion of our Board of Directors and the appointment of a Chief Business Officer. At several R&D conferences throughout the year, including in the fourth quarter at the annual meeting of the Society of Immunotherapy of Cancer (SITC), we presented preclinical data demonstrating a differentiated mode of action for PRS-343, our lead 4-1BB (CD137)-based HER-2 bispecific immuno-oncology program, which remains on track for Phase I initiation in the first half of this year," said Stephen Yoder, President and CEO. "Our targeted, inhaled asthma program, PRS-060, which engages the IL4a receptor, is differentiated from systemically administered therapies, and is on track to enter a Phase I study in mid-2017. Pieris has also completed dosing of all patients in a Phase Ib single ascending dose study of our most advanced program, PRS-080, in dialysis-dependent chronic kidney disease patients and expects to present this data in the first half of this year."

"With these accomplishments behind us, we started 2017 on a very strong note, as we have already consummated a multi-target, multi-year, transformative partnership in the immuno-oncology space with Servier, the second largest pharmaceutical company in France. This alliance includes our dual checkpoint inhibitor, PRS-332, as well as four additional bispecific programs and may be expanded to eight total programs. Notably, Pieris has the option to co-develop and retain full US rights for four of these programs, including PRS-332, and is eligible to receive up to approximately $1.8 billion in total potential milestones, and up to low double-digit royalties on potential future product sales, in addition to having received an upfront payment of approximately $31.0 million. We also recently announced a regional partnership in Japan with Aska Pharmaceutical Co., Ltd. for PRS-080, which will allow us to invest in manufacturing efficiencies and drug supply for additional clinical studies beyond our planned Phase IIa study, which we believe could help set the stage for additional potential partnerships outside of Japan, following the completion of that study. Finally, we continue to advance our preclinical portfolio of novel multispecific therapeutic proteins, as well as our existing partnerships, while continuing to explore additional collaborations. We ended the fourth quarter in a solid financial position and, considering the upfront payments we have received in the first quarter of 2017, we believe we can manage our financial runway into 2019, enabling us to reach several key value inflection points along the way."
