Company to Host an Investor Conference Call on Thursday, May 12, 2016 at 10:00 AM ET

BOSTON, MA -- (Marketwired) -- 05/11/16 -- Pieris Pharmaceuticals, Inc. (NASDAQ: 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 first quarter of 2016 and provided an update on the Company's recent developments.

"During the first quarter, we made substantial progress across both our pipeline and partnerships, in our continued efforts to build a world class protein biotherapeutic company with a balanced business model offering diversification of assets and risk mitigation. Our continued progress with our most advanced Anticalin^® program, PRS-080, for anemia of chronic disease, ensures that we are on track to complete the ongoing Phase 1b single ascending dose study in anemia patients by year end. We also advanced according to plan our asthma program, PRS-060, which targets the clinically validated IL-4 receptor (IL-4Ra), as well as our lead immuno-oncology (IO) bispecific program, PRS-343, which targets CD137 and HER-2, with each of these programs remaining on track for first-in-human study initiation in the first half of 2017. We are also advancing our earlier immuno-oncology portfolio, while advancing our partnerships with Roche, Sanofi and Daiichi-Sankyo," said Stephen Yoder, President and CEO. "Looking ahead to the rest of 2016, we expect the advancement of our IO multi-specifics franchise to further validate the repeatability of our Anticalin^®-based approach, with the objective of seeking corporate partnerships in IO beyond our Roche collaboration. Our commitment to novel IO multispecifics remains strong, and our recent PD-1 antibody license agreement with Enumeral Biomedical, which gives Pieris the ability to generate novel multispecifics for cancer involving a fusion of a novel PD-1 antibody with our proprietary Anticalins,^® affords us an opportunity to build an independent and highly competitive position around an established core component of the current IO treatment paradigm."

First Quarter Highlights:

• Advancing PRS-080 into an ongoing Phase 1 single ascending dose study in anemia of chronic disease, with expected completion by year end
• Advancing PRS-060 towards IND-enabling studies for moderate to severe asthma, and towards a first-in-human study, expected to commence in 1H17
• Advancing PRS-343 towards IND-enabling studies and a first-in-patient study for HER-2 positive cancers, expected to commence in 1H17
• Advancing PRS-342, a potential first-in-class bispecific targeting CD137 and GPC3, through preclinical studies
• Received a $6.5 million upfront payment from Roche
• Furthered our corporate collaborations with Roche, Sanofi and Daiichi Sankyo through lead identification, preclinical development and clinical development, respectively

Financial Update:

Cash Position - Cash and cash equivalents totalled $31.2 million at March 31, 2016, compared to $29.3 million at December 31, 2015. The increase was driven primarily by the receipt of the $6.5 million up-front payment from Roche, offset by operating expenses for the quarter.

R&D Expenses - Research and development expenses were $3.7 million for the quarter ended March 31, 2016, compared to $1.5 million for the quarter ended March 31, 2015. The $2.2 million increase was primarily attributable to a $0.7 million and $0.3 million increase in pre-clinical development costs for our PRS-300 series and PRS-060 programs respectively, and a $1.4 million increase in other research and development activities primarily due to additional personnel-related costs and the 5% license fee due to TUM pertaining to the Roche agreement. These were offset by a decrease in the PRS-080 program of $0.2 million as the Phase 1a trial has been completed.

G&A Expenses - General and administrative expenses for the quarter ended March 31, 2016 were $2.0 million, compared to $2.4 million for the quarter ended March 31, 2015. The $0.4 million decrease in G&A expenses was due to a reduction of professional fees of $0.8 million offset by a $0.3 million increase in personnel-related expenses, including stock-based compensation expense and increased investor relation expenses of $0.1 million.

Net Loss - Net loss was $4.2 million or ($0.10) per share for the quarter ended March 31, 2016, compared to a net loss $3.7 million or ($0.13) per share for the quarter ended March 31, 2015.
