Inventory Disclosure [Abstract]
Inventory	Inventory Inventories are stated at the lower of cost or estimated realizable value. The Company capitalizes inventory costs associated with the Company’s products when, based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to be realized; otherwise, such costs are expensed as research and development. Inventory is evaluated for impairment periodically to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated realizable value. If certain batches or units of product no longer meet quality specifications or become obsolete due to expiration, the Company records a charge to cost of goods sold to write down such unmarketable inventory to its estimated realizable value. As of June 30, 2012, the Company has $8.9 million of work in-process inventory. The value of such in-process inventory represents the costs incurred to manufacture ST-246 under the BARDA Contract. Certain of the existing units of ST-246 were initially manufactured prior to the point at which future commercialization was probable; thus, such cost was expensed as research and development in those respective periods. Additional costs incurred to complete production of courses of ST-246 will be recorded as inventory.
