We are a pharmaceutical company commercializing and developing products for the treatment of central nervous system disorders and pain. Our first commercial product, SUMAVEL® DosePro™ (sumatriptan injection) Needle-free Delivery System, was launched in January 2010. SUMAVEL DosePro offers fast-acting, easy-to-use, needle-free subcutaneous administration of sumatriptan for the acute treatment of migraine and cluster headache in a pre-filled, single-use delivery system. SUMAVEL DosePro is the first drug product approved by the FDA that allows for the needle-free, subcutaneous delivery of medication. Our lead product candidate, Zohydro (hydrocodone bitartrate) extended-release capsules (formerly ZX002), is a novel, oral, single-entity controlled-release formulation of hydrocodone currently in Phase 3 clinical trials for the treatment of moderate to severe chronic pain in patients requiring around-the-clock opioid therapy. SUMAVEL DosePro and Zohydro each has the potential to address significant unmet medical needs and become important and widely-used additions to the treatment options available to patients and physicians in the United States' multi-billion dollar migraine and chronic pain markets, respectively.
