Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. Actual results may differ materially from those estimates.

Intangible Assets

Intangible assets

Effective January 1, 2012, the Company launched LAVIV and as a result, the research and development intangible assets related to the Company’s primary study are considered finite-lived intangible assets and are being amortized over 12 years. For the three months ended June 30, 2013 and 2012, the Company amortized $138, respectively, for the intangible assets. For the six months ended June 30, 2013 and 2012, the Company amortized $276, respectively, for the intangible assets.

Finite-lived intangible assets are recorded at cost, net of accumulated amortization and, if applicable, impairment charges. Amortization of finite-lived intangible assets is provided over their estimated useful lives on a straight-line basis. We review our finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. There was no impairment expense recognized during the three and six months ended June 30, 2013 and 2012.

Loss Per Share Data

Loss per share data

Basic and diluted net loss attributable to common stockholders per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding. For all periods presented, the outstanding shares of common stock options, preferred and common warrants have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted-average shares used to calculate both basis and dilutive loss per share are the same.

The following potentially dilutive securities have been excluded from the calculations of diluted net loss per share as their effect would be anti-dilutive:

	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012
Shares of convertible preferred stock		—		1,792,320		—		1,792,320
Shares underlying options outstanding		744,007		563,390		744,007		563,390
Shares underlying warrants outstanding		6,108,050		5,329,222		6,108,050		5,329,222

Stock Warrants

The Company accounts for stock warrants as either equity instruments or derivative liabilities depending on the specific terms of the warrant agreement. Stock warrants are accounted for as a derivative in accordance with ASC 815 if the stock warrants contain “down-round protection” and therefore, do not meet the scope exception for treatment as a derivative. Since “down-round protection” is not an input into the calculation of the fair value of the warrants, the warrants cannot be considered indexed to the Company’s own stock which is a requirement for the scope exception as outlined under ASC 815. The Company will continue to classify the fair value of the warrants that contain “down-round protection” as a liability until the warrants are exercised, expire or are amended in a way that would no longer require these warrants to be classified as a liability. Effective December 31, 2011, the Company utilized the Monte Carlo simulation valuation method to value the liability-classified warrants until September 30, 2012 when the Company concluded that the Black-Scholes option pricing model was an appropriate valuation method due to the assumption that no future financing would be expected at a price lower than the current exercise price and the majority of the warrants were converted to equity-classified warrants on October 9, 2012.

Liability-classified Warrants

Effective December 31, 2011, the Company utilized the Monte Carlo simulation valuation method to value the liability classified warrants until September 30, 2012 when the Company concluded that the Black-Scholes option pricing model was an appropriate valuation method due to the assumption that no future financing would be expected at a price lower than the current exercise price and the majority of the warrants were converted to equity-classified warrants on October 9, 2012.
