Pieris has established a proprietary portfolio of unique product opportunities in the immunology-related areas of immuno-oncology and asthma, while also having developed programs in other areas including anemia. Based on the promise of our unique therapeutic approach in immuno-oncology and respiratory disease, we intend to make these two core therapeutic areas of the Company, with each indication now anchored by a major alliance: AstraZeneca in respiratory disease and Servier in immuno-oncology.

Pieris maintains strategic alliances with AstraZeneca, Seattle Genetics and Servier, each of which includes programs for which Pieris has U.S. commercial rights. To maximize the value of our pipeline, we are continuing to explore new partnerships to support the development and commercialization of the technology.  As part of the company’s ongoing transformation into an immunology-focused organization, it entered into a Japanese partnership for its anemia program, PRS-080, and will explore out-licensing opportunities in other territories following the completion of an ongoing Phase IIa study for this program.
