Research and Development [Abstract]
Research and Development Expense	Research and Development Expense The Company records inventory, manufactured for sale of a product candidate, when the product candidate is considered to have a high likelihood of regulatory approval and the related costs are expected to be recoverable through sales. In determining whether or not to record such inventories, the Company evaluates, among other factors, information regarding the product candidate's safety and efficacy, the status of regulatory submissions and communications with regulatory authorities and the outlook for commercial sales. Prior to October 1, 2016, all costs associated with batches of inventory and manufactured for sale of our product candidates, were charged to research and development as incurred. Beginning in the fourth quarter of 2016, we began capitalizing inventory costs for TRULANCE in preparation for its planned launch in the U.S.
