The FDA grants orphan drug designation to drugs and biologics that are intended for the treatment of rare diseases that affect fewer than 200,000 people in the U.S. Orphan drug status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including tax credits for qualified clinical trials costs, exemptions from certain FDA application fees, and seven years of market exclusivity upon regulatory product approval.

About AML
Leukemia is a cancer of the white blood cells and the acute forms of leukemia can manifest quickly and leave patients with limited treatment options. AML is the most common type of acute leukemia in adults. It occurs when a clone of leukemic progenitor white blood cells proliferates in the bone marrow suppressing the production of normal blood cells. In order to qualify for a curative bone marrow transplant, patients must first undergo induction therapy. The current standard of care is the combining of 2 chemotherapeutic drugs, always including an anthracycline intended to induce a CR or complete response, which has not improved since it was first used in the 1970’s. We estimate that it has the same cure rate of about 20% as then. Currently, the only viable long term option for acute leukemia patients is a bone marrow transplant for those 20%, which is successful in a significant number of patients.

About Annamycin
Annamycin is an anthracycline intended for the treatment of relapsed or refractory AML. Annamycin is a unique liposome formulated anthracycline (also referred to in literature as "L-Annamycin") that has been designed to produce little to no cardiotoxicity and avoid the multidrug resistance mechanisms that often defeat current anthracyclines. It has been tested in 114 patients in 6 clinical trials, 3 of which focused on leukemia, with little to no cardiotoxicity and 3 of those clinical trials focused on leukemia. The Company is working with the FDA on an investigative new drug application for a Phase I/II trial for second line treatment of relapsed or refractory AML, for which no approved therapy currently exists.

"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) (Free SITC Whitepaper), 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."

Fourth Quarter and 2016 Highlights:

Advanced PRS-080 through an ongoing Phase Ib single ascending dose study in anemia of chronic disease, having completed patient dosing in early 2017, which will assess the effect of PRS-080 on iron mobilization and transferring saturation in dialysis-dependent anemia patients.
Advanced PRS-343 through IND-enabling studies and towards a first-in-patient study for HER-2 positive cancers.
Advanced PRS-060, a novel inhaled therapeutic for moderate to severe asthma, through IND-enabling studies.
Advanced our novel multi-checkpoint blockade bispecific, PRS-332, comprised of an anti-PD-1 antibody genetically linked to an existing Anticalin against an undisclosed checkpoint, through preclinical studies.
Strengthened our Board of Directors with the addition of Julian Adams, Ph.D. and Christopher Kiritsy.
Dr. Adams is the former President of Research & Development at Infinity Pharmaceuticals. During his career, Dr. Adams has had global responsibility for multiple drug discovery programs, including the discovery and development of Velcade (bortezomib), a proteasome inhibitor for cancer therapy, and Viramune (nevirapine) for HIV.

Fiscal Year Financial Update:

Cash Position – Cash and cash equivalents totalled $29.4 million as of December 31, 2016, compared to $29.3 million as of December 31, 2015. The increase in cash was driven primarily by the $16.5 million gross private placement financing completed in June 2016 offset by cash used in our operating activities.

R&D Expense ­ – Research and development expenses were $19.7 million for the year ended December 31, 2016, compared to $8.2 million for the year ended December 31, 2015. The $11.5 million increase was primarily due to a $5.6 million increase in pre-clinical development and CMC costs for PRS-343 as we carry out IND enabling studies and increased development costs for our other PRS-300 series programs, and a $1.2 million increase in CMC costs associated with PRS-060 as we carry out IND enabling studies, offset by a $0.2 million decrease for our PRS-080 program due to the completion of our Phase Ia clinical trial in 2015. Other R&D expenses also increased by $4.9 million primarily due to higher personnel-related expenses including stock-based compensation expense and increased costs for license fees, as well as higher legal and consulting costs. Additionally, costs for general lab supplies increased due to an upturn in program activities.

G&A Expense – General and administrative expenses for the year ended December 31, 2016 were $8.9 million, compared to $8.4 million for the year ended December 31, 2015. The $0.5 million increase in G&A expenses is primarily due to an increase in personnel-related costs, including stock-based compensation expense, higher legal and recruiting costs, and costs associated with being a public company such as financial printing costs and transaction fees.

Net Loss – Net loss was $22.8 million or ($0.55) per share for the year ended December 31, 2016, compared to a net loss $14.1 million or ($0.41) per share for the year ended December 31, 2015.

Upcoming Milestones:

The Company expects to reach the following milestones during 2017:

PRS-080: Present Phase Ib data and initiate a multi-dose, Phase IIa study in dialysis-dependent anemia patients during the second quarter, which we estimate will be completed by the end of 2017.
PRS-343: Initiate a Phase I multi-ascending dose study involving a range of HER2-positive solid cancers representing unmet medical needs (such as breast, gastrointestinal and bladder cancers) in the first half of 2017.
PRS-332: Progress preclinical evaluation in collaboration with Servier, with IND-enabling activities planned for later in 2017.
PRS-060: Initiate a Phase I study in mid-2017.
Upcoming Scientific Presentations:

PRS-343: IND-enabling data informing the design of a first-in-patient clinical trial for PRS-343 will be presented in a poster session at next month’s Annual Meeting of the American Association for Cancer Research (AACR) (Free AACR Whitepaper) to be held in Washington D.C. The poster will be presented on Tuesday, April 4, 2017 in a session from 8am to 12pm EDT.
