Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company evaluated all events or transactions that occurred after December 31, 2018 up through the date these financial statements were issued. Other than as disclosed elsewhere in the notes to the consolidated financial statements, the Company did not have any material subsequent events. On March 6, 2019, the Company entered into a Warrant Exercise Agreement, or the Exercise Agreement, with one of the holders of our warrants issued in July 2018. Pursuant to the Exercise Agreement, such holder agreed that it would cash exercise up to 3,800,000 of its warrants issued in July 2018 into shares of common stock at a reduced exercise price of $1.10 per share for any warrants exercised prior to May 31, 2019. In addition to reducing the exercise price of the warrants, the Exercise Agreement also provides for the issuance of new warrants to purchase up to an aggregate of approximately 3,800,000 shares of common stock at an exercise price of $1.40 per share, or New Warrants, to be issued on a share-for-share basis in an amount equal to the number of the warrants that are cash exercised by the holder by May 31, 2019. To date, the holder has exercised approximately 1.2 million warrants for gross proceeds of $1.3 million and approximately 1.2 million New Warrants were issued. The Company may receive aggregate gross proceeds of up to approximately $4.2 million from the cash exercise if all of the warrants under the Exercise Agreement are exercised.
