2015 Financial Results and Corporate Update

Company to Host an Investor Conference Call on Wednesday, March 23, 2016 at 10:00 AM ET

BOSTON, MA — (Marketwired) — 03/22/16 — Pieris Pharmaceuticals, Inc. (NASDAQ: PIRS), a biotechnology company advancing novel biotherapeutics through its proprietary Anticalin® technology platform, announced today 2015 corporate highlights, a clinical development overview and financial results for the fiscal year ending December 31, 2015.

“I’m pleased to report that 2015, and particularly the fourth quarter, was a period of significant progress for Pieris Pharmaceuticals, both financially and in terms of program and partner development. In the fourth quarter, we announced a major oncology collaboration agreement with Roche, received development milestone payments from collaborators Daiichi-Sankyo and Sanofi and initiated IND-enabling activities for PRS-343, our lead immuno-oncology bispecific drug candidate targeting CD137 and HER2,” commented Pieris’ President and Chief Executive Officer, Stephen Yoder. “Earlier in the year, we completed a public offering of common stock raising $25.8M in total net proceeds, we completed a successful Phase I clinical trial for PRS-080, our anti-hepcidin Anticalin® therapeutic protein designed to treat anemic patients, and we initiated IND-enabling activities for PRS-060, a potential first-in-class inhaled biologic targeting IL4Ra to address asthma patients, collectively setting the stage for an eventful 2016.”

2015 Corporate Highlights:

 

    Announced the Company’s first immuno-oncology research collaboration and license agreement with world leading oncology company, Roche, with an approximately $6.5 million upfront payment which was received in January 2016 and the potential to receive approximately $415 million in milestones

 

    Presented data from a Phase I clinical study with PRS-080, an Anticalin hepcidin antagonist, in healthy male volunteers at the 57th Annual Meeting of the American Society of Hematology (ASH), demonstrating safety, tolerabilty and desired half-life, while confirming the mode of action (iron mobilization)

 

    Appointed significant key personnel — Dr. Jean-Pierre Bizzari, formerly of Celgene Corporation and Sanofi-Aventis, to our board of directors, Dr. Louis A. Matis as SVP & Chief Development Officer, Dr. Mary Fitzgerald as VP of Respiratory Medicine, and Darlene Deptula-Hicks as SVP and Chief Financial Officer

 

    Established US headquarters in Boston, MA

 

    Achieved a third payment-based milestone in our R&D collaboration with Sanofi, who continues advancing the tetraspecific Anticalin-based program in preclinical studies for pseudomonas-related illness

 

    Dosed the first subject in a Phase I clinical study with collaboration partner Daiichi Sankyo for the parties’ lead partnered Anticalin program, also triggering a milestone payment, the eighth milestone payment overall under the collaboration agreement


    Presented preclinical data for PRS-343, the Company’s Anticalin-based CD137/HER2 bispecific and lead immuno-oncology program, demonstrating superior drug-like properties and tumor-targeted immune responses distinct from conventional anti-CD137 monoclonal antibodies, triggering development candidate nomination and initiation of IND-enabling activities

 

    Announced a $AUS 500,000 research grant to the University of Melbourne to further develop PRS-060 in immunological diseases

 

    Completed a successful public offering of common stock, including the overallotment, raising $25.8M in total net proceeds

Pipeline Update:

PRS-080

Pieris completed a Phase I clinical trial for PRS-080, an anti-hepcidin Anticalin therapeutic protein designed to treat anemia in chronic kidney disease patients suffering from functional iron deficiency (FID). The clinical data were presented at the 2015 American Society of Hematology (ASH) in an oral presentation that discussed the favorable safety profile of the drug and demonstrable proof of mechanism. PRS-080 was well tolerated by the 48 healthy male subjects with no serious adverse events. Among all subjects receiving the PRS-080 doses of 1.2 mg/ml or higher in the six dose study, ranging from 0.08 to 16 mg/kg, statistically significant increases in total serum iron mobilization were observed relative to the placebo (p=0.005). PRS-080 currently is undergoing a first-in-patient study in end-stage renal disease (ESRD) patients exhibiting FID anemia.

PRS-060

PRS-060 is a potent antagonist of IL4Ra and is being developed for pulmonary delivery to treat asthma. With direct delivery into the lungs, PRS-060 may allow for low doses compared to subcutaneously administered antibody approaches, while offering a more convenient administration regimen and a potentially superior therapeutic index. The Company has shown proof of concept in animal models of lung inflammation, as well as feasibility of pulmonary delivery in multiple formulations. PRS-060 currently is in IND-enabling studies and has the potential to be a first-in-class inhaled biologic. PRS-060 is currently undergoing IND-enabling activities, and we expect to begin a Phase I clinical trial with PRS-060 in 2017.

PRS-343

PRS-343 is a bivalent, bispecific fusion protein targeting CD137 (4-1BB) and HER2 comprising an agonistic CD137-targeting Anticalin genetically linked to a HER2-targeting antibody. CD137 is a key costimulatory immunoreceptor and a member of the TNF-receptor (TNFR) superfamily. While multiple lines of evidence show that CD137 is a highly promising therapeutic target in cancer, current mAb approaches are not designed to achieve a tumor-mediated activation and, therefore, may display toxicity and a limited therapeutic window due to peripheral T cell and NK cell activation. To overcome this limitation, PRS-343 has been designed to promote CD137 clustering by bridging CD137-positive T cells with HER2-positive tumor cells, thereby providing a potent costimulatory signal to tumor antigen-specific T cells. Data from ex vivo T cell assays and a humanized mouse model of cancer support the intended mode of action of tumor-localized costimulatory T cell activation with an enhanced therapeutic index compared to anti-CD137 antibody approaches. PRS-343 currently is in IND-enabling studies.


Financial Update:

Cash Position—Cash and cash equivalents totaled $29.3 million at December 31, 2015, compared to $18.5 million at December 31, 2014. The increase was driven primarily by the company’s common offering completed in July 2015.

R&D Expenses—Research and development expenses were $8.2 million for the year ended December 31, 2015, compared to $5.6 million for the year ended December 31, 2014. The $2.6 million increase was primarily attributable to $2.3 million and $0.4 million in pre-clinical development for our PRS-300 series and PRS-060 programs respectively, $0.2 million in initial clinical development activities for our PRS-080 program, offset by a $0.3 million decrease in other R&D activities.

G&A Expenses—General and administrative expenses for the year ended December 31, 2015 were $8.4 million, compared to $7.0 million for the year ended December 31, 2014. The $1.4 million increase in G&A expenses are due primarily to costs incurred for operating as a public Company such as investor relations costs and D&O insurance premiums, increased personnel-related expenses including approximately $0.8 million in non-cash stock based compensation expense.

Net Loss—Net loss was $14.1 million or ($0.41) per share for the year ended December 31, 2015, compared to a net loss $9.8 million or ($0.71) per share for the year ended December 31, 2014.
