Subsequent Events [Abstract]
Subsequent Events	Note 9. Subsequent Events In April 2015, we raised gross proceeds of approximately $25 million through a public offering of 35,715,000 Units. Each Unit consists of one share of our common stock and a warrant to purchase three-quarters of a share of our common stock. The warrants have an exercise price of $0.85 per share, are exercisable immediately, and will expire five years from the date of issuance. We also granted the underwriters a thirty day option to purchase up to an additional 5,357,250 shares of common stock and/or warrants to purchase up to an additional 4,017,938 shares of common stock to cover over-allotments, if any. The underwriters exercised the over-allotment option for the warrants and so, in April 2015, we issued warrants to purchase up to an additional 4,017,938 shares of common stock. The shares were offered under our effective shelf registration statement previously filed with the SEC.
