About PIRS

Pieris Pharmaceuticals, Inc. is a clinical-stage biotechnology company that discovers and develops Anticalin-based drugs to target validated disease pathways. The Company’s clinical pipeline includes an inhaled IL-4Ra antagonist Anticalin protein to treat asthma, an immuno-oncology (IO), bispecific targeting HER2 and 4-1BB, and an IO bispecific targeting PD-L1 and 4-1BB. Its lead respiratory Anticalin based drug candidate, elarekibep, antagonizes IL-4Ra, thereby inhibiting IL-4 and IL-13, two cytokines, which are small proteins mediating signaling between cells within the human body, known to be key mediators in the inflammatory cascade that drive the pathogenesis of asthma and other inflammatory diseases. Its IO portfolio also includes additional drug candidates beyond PRS-344/S095012 that are multi-specific Anticalin-based fusion proteins designed to engage immunomodulatory targets, comprising a variety of multifunctional biotherapeutics.
