Description of Business
We are an innovative biopharmaceutical company dedicated to discovering, developing and delivering best-in-class medicines to people with difficult-to-treat diseases. We combine proven scientific expertise with a passion for developing novel small molecule drugs that target emerging disease pathways. We have worldwide development and commercialization rights to all of our development candidates and early discovery programs, subject to certain financial obligations to our current licensor and former development partners. IPI-145, our lead product candidate, is a potent, oral inhibitor of Class I delta and gamma isoforms of phosphoinositide-3-kinase, or PI3K, which we are investigating in both hematologic malignancies and inflammatory diseases. The PI3Ks are a family of enzymes involved in multiple cellular functions, including cell proliferation and survival, cell differentiation, cell migration and immunity.
