About ChemoCentryx

ChemoCentryx, Inc. is a clinical-stage biopharmaceutical company focused on discovering, developing and commercializing orally-administered therapeutics that target the chemokine and chemoattractant systems in order to treat autoimmune diseases, inflammatory disorders and cancer. The chemokine system is a biological network that regulates inflammation via a collection of secreted chemokine molecules, or ligands, and their specific cell surface receptors.

The Company's lead independent drug candidate, CCX140, a CCR2 inhibitor, has been shown to be safe and well tolerated while demonstrating clinical activity on glycemic indices in a Phase II clinical trial in type 2 diabetics, and is now in Phase II clinical development for the treatment of diabetic nephropathy.
