Pieris Pharmaceuticals, Inc.(NasdaqCM:PIRS) dropped from Russell Microcap Index

Pieris Pharmaceuticals, Inc. is a biotechnology company, which discovers and develops Anticalin-based drugs to target validated disease pathways. The Company’s clinical pipeline consists of immuno-oncology (IO), bispecific in partnership with collaborators, including S095012 (also referred to as PRS-344) targeting PD-L1 and 4-1BB, SGN-BB228 (also referred to as PRS-346) targeting CD228 and 4-1BB, and BOS-342 (also referred to as PRS-342) targeting GPC3 and 4-1BB. Its Anticalin platform technology focuses on low molecular-weight Anticalin proteins that can bind tightly and specifically to a diverse range of targets. The Anticalin technology is modular, which allows it to design multimeric Anticalin based bi- and multi- specific proteins to bind with specificity to two or more targets at the same time. S095012 consists of a PD-L1-targeting antibody and 4-1BB-targeting Anticalin proteins genetically fused to each arm of the C-terminal heavy chain of the antibody.
