Stockholders' Equity [Abstract]

Stockholders' Equity

Note 2 — Stockholders’ Deficit

Preferred Stock — Our board of directors has the authority, without action by the stockholders, to designate and issue up to 100,000 shares of preferred stock in one or more series and to designate the rights, preferences and privileges of each series, any or all of which may be greater than the rights of our common stock. We have designated 1,000 shares as Series B Preferred Stock (“Series B Preferred”) and 90,000 shares as Series A Junior Participating Preferred Stock (“Series A Preferred”). No shares of Series B Preferred or Series A Preferred are outstanding. In March 2014, we designated 1,200 shares as Series C Convertible Preferred Stock (“Series C Preferred”). In August 2015, we designated 220 shares as Series D Convertible Preferred Stock (“Series D Preferred”).

In March 2014, we entered into a Securities Purchase Agreement with certain investors pursuant to which we sold 1,200 shares of Series C Preferred, and price adjustable warrants to purchase up to 6.0 million shares of our common stock at an initial exercise price of $0.75 per share, for an aggregate purchase price of $6.0 million. The exercise price of the warrants is subject to reduction in the event of certain dilutive stock issuances at any time while the warrants are outstanding, but not to be reduced below $0.28 per share. Each share of Series C Preferred has a stated value of $5,000 per share and is convertible into shares of common stock at a conversion price of $0.75 per share. The Series C Preferred is initially convertible into an aggregate of 8,000,000 shares of our common stock, subject to certain limitations and adjustments, has no stated dividend rate, is not redeemable and has voting rights on an as-converted basis.

To account for the issuance of the Series C Preferred and warrants, we first assessed the terms of the warrants and determined that, due to certain anti-dilution provisions, they should be recorded as derivative liabilities. We determined the fair value of the warrants on the issuance date and recorded a liability of $6.5 million. Since the fair value of the warrants exceeded the total proceeds received of $6.0 million, we recorded a loss of $0.5 million upon issuance, which is included in the change in fair value of price adjustable warrants in the consolidated statements of operations. The discount of $6.0 million on the Series C Preferred resulting from the allocation of the entire proceeds to the warrant was accreted as a dividend on the Series C Preferred through the earliest conversion date, which was immediately. The Series C Preferred dividend of $6.0 million was recorded as both a debit and a credit to additional paid-in capital and as a deemed dividend on the Series C Preferred in determining net loss applicable to common stock holders in the consolidated statements of operations. We incurred $0.07 million of stock issuance costs in conjunction with the Series C Preferred, which were netted against the proceeds.

In August 2015, we entered into a Securities Purchase Agreement with certain investors pursuant to which we sold 220 shares of Series D Preferred, and warrants to purchase up to 3.44 million shares of our common stock at an initial exercise price of $0.40 per share, for an aggregate purchase price of $1.1 million. The warrants issued in connection with Series D Preferred contain a “down round” provision whereby the exercise price per share to purchase common stock covered by these warrants is subject to reduction in the event of certain dilutive stock issuances at any time within the two year anniversary of the issuance date, but not to be reduced below $0.28 per share. Each share of Series D Preferred has a stated value of $5,000 per share and is convertible into shares of common stock at a conversion price of $0.40 per share. The Series D Preferred is initially convertible into an aggregate of 2,750,000 shares of our common stock, subject to certain limitations and adjustments, has a 5% stated dividend rate, is not redeemable and has voting rights on an as-converted basis.

  To account for the issuance of the Series D Preferred and warrants, we first assessed the terms of the warrants and determined that, due to the “down round” provision, they should be recorded as derivative liabilities. We determined the fair value of the warrants on the issuance date and recorded a liability of $0.6 million. We also recorded a discount of $0.6 million on the Series D Preferred resulting from the allocation of proceeds to the warrants. We then determined the effective conversion price of the Series D Preferred which resulted in a beneficial conversion feature of $0.7 million. The beneficial conversion feature was recorded as both a debit and a credit to additional paid-in capital and as a deemed dividend on the Series D Preferred in determining net income applicable to common stock holders in the consolidated statements of operations. We incurred $0.01 million of stock issuance costs in conjunction with the Series D Preferred, which were netted against the proceeds.

Common Stock — Holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the holders of our common stock. Subject to the rights of the holders of any class of our capital stock having any preference or priority over our common stock, the holders of our common stock are entitled to receive dividends that are declared by our board of directors out of legally available funds. In the event of our liquidation, dissolution or winding-up, the holders of common stock are entitled to share ratably in our net assets remaining after payment of liabilities, subject to prior rights of preferred stock, if any, then outstanding. Our common stock has no preemptive rights, conversion rights, redemption rights or sinking fund provisions, and there are no dividends in arrears or default. All shares of our common stock have equal distribution, liquidation and voting rights, and have no preferences or exchange rights. Our common stock currently trades on the OTCQB tier of the OTC Markets.

In January 2015, we issued 0.12 million common shares with a value of $0.075 million to Novosom as the equity component owed under our December 2014 license agreement with MiNA Therapeutics.

In May 2015, we issued 0.21 million common shares with a value of $0.12 million to Novosom as the equity component owed as a result of an accelerated milestone payment under our December 2011 license agreement with Mirna Therapeutics.

In June 2015, an investor converted 90 shares of Series C Preferred into 0.6 million shares of common stock.

Warrants — In January 2015, an investor exercised warrants to purchase 2,500 shares of common stock at an exercise price of $0.28.

From January to September 2015, we issued warrants to purchase up to an aggregate of 0.102 million common shares to a vendor providing scientific and development consulting services to our company. The fair value of these warrants at issuance was $0.065 million of which $0.05 million was accrued at December 31, 2014.
