Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes There is no income tax benefit recognized for the three months ended June 30, 2013 and 2012 and for the six months ended June 30, 2013 and 2012 due to the Company’s history of net losses combined with an inability to confirm recovery of the tax benefits of the Company’s losses and other net deferred tax assets. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Due to the Company’s history of net losses incurred from inception, no income tax benefit has been recorded and the corresponding deferred tax assets have been fully reserved as the Company cannot sufficiently be assured that these deferred tax assets will be realized. At June 30, 2013, the Company has loss carryforwards for federal income tax purposes of approximately $225,100 available to offset future taxable income and federal and state research and development tax credits of approximately $6,600, prior to consideration of annual limitations that may be imposed under Section 382. These carryforwards will begin to expire in 2022.
