Pieris Pharmaceuticals and Seattle Genetics Announce
Multi-Program Immuno-Oncology Collaboration
-Companies to Evaluate Novel Bispecific Immuno-Oncology Agents that Combine Pieris’ Anticalin
Technology with Select Seattle Genetics Cancer-Targeted Antibodies-
Boston, MA and Bothell, WA (Marketwired)—02/09/2018 – Pieris Pharmaceuticals,
Inc. (NASDAQ: PIRS), a clinical-stage biotechnology company advancing novel
biotherapeutics through its proprietary Anticalin® technology platform for cancer,
respiratory and other diseases, and Seattle Genetics, Inc. (NASDAQ: SGEN), a global
biotechnology company developing innovative, targeted therapies for cancer, today
announced they have entered into a collaboration and license agreement with the goal of
developing multiple targeted bispecific immuno-oncology treatments for solid tumors and
blood cancers.
The collaboration leverages the expertise and core technologies of both companies to
develop novel Antibody-Anticalin fusion proteins. Pieris’ proprietary suite of agonistic
costimulatory Anticalin proteins, when fused to a tumor-targeting antibody, can activate
the immune system preferentially in the tumor microenvironment. Seattle Genetics,
through its industry-leading work in the field of antibody-drug conjugates (ADCs), has a
substantial portfolio of cancer targets and tumor-specific monoclonal antibodies from which
programs will be selected for the collaboration. The bispecific drug candidates in this
alliance will be designed to enable the patient’s immune cells to specifically attack tumors.
“As the industry leader in ADCs, we bring deep expertise in targeted cancer therapy
development to this collaboration with Pieris,” said Dennis Benjamin, Ph.D., Senior Vice
President of Research at Seattle Genetics. “Pieris’ Anticalin technology and Antibody-
Anticalin bispecific approach are intended to overcome the limitations of currently available
immuno-oncology products. This partnership leverages our cancer targets and tumor-
specific antibodies to explore multiple novel bispecific combinations, with the goal of
developing targeted therapies that improve outcomes for people with cancer.”
Under the terms of the agreement, Seattle Genetics will pay Pieris a $30 million upfront
fee, tiered royalties on net sales up to low double-digits, and up to $1.2 billion in total
success-based payments across three product candidates. The companies will pursue
multiple Antibody-Anticalin fusion proteins during the research phase, and Seattle
Genetics has the option to select up to three therapeutic programs for further development.
Prior to the initiation of a pivotal trial, Pieris may opt into global co-development and US
commercialization of the second program and share in global costs and profits on a 50/50
basis. Seattle Genetics will solely develop, fund and commercialize the other two
programs.
“Pieris was the first company to bring a tumor-targeted costimulatory bispecific to patients
with PRS-343, and we are looking forward to broadening our bispecific pipeline through
this alliance. Seattle Genetics is a compelling partner for Pieris with a long-standing
commitment to oncology,” said Stephen S. Yoder, President and CEO of Pieris. “The
collaboration combines the excellent protein engineering and translational capabilities of
both companies, utilizing Seattle Genetics’ tumor-targeted monoclonal antibodies and
Pieris’ Anticalin proteins to create novel bispecifics. This is our third significant alliance
since January 2017 and is in alignment with our goal to create a respiratory- and oncology-
focused commercial company.”
About Anticalin® Therapeutics:
Anticalin® proteins are derived from lipocalins, small human proteins that naturally bind,
store and transport a wide spectrum of molecules. Anticalin® proteins feature the typical
four-loop variable region and a rigidly conserved beta-barrel backbone of lipocalins, which,
together, form a shapeable cup-like binding pocket. Proprietary to Pieris, Anticalin®
proteins are a novel class of protein therapeutics validated in the clinic and by partnerships
with leading pharmaceutical companies. Anticalin® is a registered trademark of Pieris.
About Pieris Pharmaceuticals:
Pieris is a clinical-stage biotechnology company that discovers and develops Anticalin protein-
based drugs to target validated disease pathways in a unique and transformative way. Our
pipeline includes immuno-oncology multi-specifics tailored for the tumor microenvironment, an
inhaled Anticalin® protein to treat uncontrolled asthma and a half-life-optimized Anticalin®
protein to treat anemia. Proprietary to Pieris, Anticalin proteins are a novel class of therapeutics
