About PharmacyclicsBuilding a pipeline of novel drugs

Pharmacyclics Inc. is a clinical-stage biopharmaceutical company focused on developing and commercializing innovative small-molecule drugs for the treatment of immune mediated disease and cancer. Our pharmaceutical drug development candidates are synthetic small-molecules designed to target key biochemical pathways involved in human diseases with critical unmet needs. We currently have four proprietary drug candidates under clinical development and one drug candidate under preclinical CloseclosePreclinicalStudies done in animals or in cell cultures to show that a new drug should be tested in humans. development, and a lead compound undergoing preclinical optimization.
