BOSTON, MA--(Marketwired - February 27, 2017) - Pieris Pharmaceuticals, Inc. (PIRS), a clinical-stage biotechnology company advancing novel biotherapeutics through its proprietary Anticalin® technology platform, today announced that it has granted ASKA Pharmaceutical Co., Ltd., an independent Japanese pharmaceutical company with annual sales of approximately $400 million, an exclusive option to license development and commercial rights to Pieris' anemia drug, PRS-080, in Japan and certain other Asian markets following completion of a multi-dose Phase 2a study to be conducted by Pieris in dialysis-dependent anemia patients.
PRS-080 is a highly potent inhibitor of hepcidin, a key regulator of iron metabolism. Elevated hepcidin levels both prohibit iron uptake from dietary consumption and block the release of iron from body storage cells, such as hepatocytes and macrophages. Excess hepcidin is, therefore, often the root cause of iron deficiency and iron-restricted reduction of erythropoiesis, resulting in anemia in patients with chronic kidney disease (CKD) and other conditions. Current treatment options, which include erythropoietin stimulating agents and iron supplements, are associated with side effects, and not all patients respond to those agents. PRS-080 seeks to overcome these limitations by neutralizing hepcidin directly. A Phase 1 study conducted in healthy volunteers demonstrated that a single dose of PRS-080 was well tolerated and resulted in a dose-dependent increase in serum iron. Pieris has completed dosing of all patients in a Phase 1b study in CKD patients on hemodialysis and will next pursue a multi-dose, Phase 2a study in the same patient population, which is scheduled for completion in the second half of 2017.
Under the terms of the option agreement, Pieris will receive an immediate option payment of $2.75 million USD from ASKA. Following an analysis period after the completion of the planned Phase 2a study conducted by Pieris, ASKA may exercise its option to obtain an exclusive license to develop and commercialize PRS-080 in Japan, South Korea and certain other Asian markets (excluding China). Should ASKA exercise the option, Pieris would be eligible for more than $80 million USD in combined option exercise fee and milestones associated with development and commercialization of PRS-080 in the first indication in Japan. Pieris may receive further development milestones in additional indications, as well as in other countries within the ASKA territory. Pieris may also receive double-digit royalties on net sales of PRS-080 up to the mid- to high-teens.
"We are pleased to have found a very committed partner for PRS-080 in a key Asian market," stated Stephen Yoder, President and Chief Executive Officer of Pieris. "Importantly, this deal enables us to invest in improving drug manufacturing efficiencies while conducting our Phase 2a trial to enable seamless drug supply for future clinical studies by ASKA and other partners we may seek in other territories, as we focus our proprietary pipeline in immunology-related areas for long-term value creation."
"Anemia in hemodialysis patients represents a substantial medical need in Japan, as physicians are not comfortable prescribing high doses of erythropoietin stimulating drugs, such as EPO and iron supplements. PRS-080 is well positioned to address this medical need in the future. We are thus very excited to have secured an option for this highly innovative drug," stated Takashi Yamaguchi, President and Representative Director at ASKA Pharmaceutical.
"We are looking forward to conducting the planned Phase 2a study with PRS-080," stated Dr. Louis Matis, Senior Vice President and Chief Development Officer of Pieris. "At the same time, we continue to focus on readying a highly differentiated pipeline of novel biotherapeutics for clinical development, with our lead Immuno-Oncology bispecific drug candidate, PRS-343, scheduled to enter a first-in patient trial in the first half of 2017, as well as our inhaled drug candidate for the local treatment of asthma, PRS-060, anticipated to begin a first-in-human study around the middle of 2017."
