Description of Business
We are a biopharmaceutical company with peptide-based new chemical entities rusfertide and JNJ-2113 (formerly known as PN-235) in different stages of development, all derived from our proprietary discovery technology platform. Our clinical programs fall into two broad categories of diseases; (i) hematology and blood disorders, and (ii) inflammatory and immunomodulatory diseases. Figure 1: Our Product Pipeline [[Image Removed: Graphic]] Rusfertide Our most advanced clinical asset, rusfertide (generic name for PTG-300), is an injectable hepcidin mimetic in development for the potential treatment of erythrocytosis, iron overload and other blood disorders and is wholly owned. Hepcidin is a key hormone in regulating iron equilibrium and is critical to the proper development of red blood cells. Rusfertide mimics the effect of the natural hormone hepcidin, but with greater potency, solubility and stability.
