Basis of Presentation

BASIS OF PRESENTATION

The accompanying interim unaudited financial statements and related disclosures are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s financial statements for the year ended December 31, 2013 included in the Company’s Registration Statement on Form S-1, as amended (File No. 333-193204) (Registration Statement), which was declared effective by the Securities and Exchange Commission (SEC) on May 1, 2014. The financial information as of June 30, 2014, the three and six months ended June 30, 2014 and 2013 is unaudited but, in the opinion of management, all adjustments, consisting only of normal recurring accruals, considered necessary for a fair statement of the results of these interim periods have been included. The balance sheet data as of December 31, 2013 was derived from audited financial statements. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.

The Company’s initial public offering of common stock (Initial Public Offering) was completed on May 7, 2014.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Reverse stock split

On January 23, 2014, the Company’s board of directors and stockholders approved an amendment to the restated certificate of incorporation to effect a one-for-twelve reverse stock split of the Company’s common stock, options for common stock, convertible preferred stock, and warrants for convertible preferred stock which became effective on May 1, 2014, prior to the effectiveness of the Registration Statement (the Reverse Stock Split). The par value and the authorized shares of the common and convertible preferred stock were not adjusted as a result of the Reverse Stock Split. All issued and outstanding common stock, options for common stock, convertible preferred stock, and rights and warrants for convertible preferred stock, as well as the exercise price of each option for common stock, each right and each warrant for convertible preferred stock, and each right for warrants for convertible preferred stock and the conversion price for convertible preferred stock, have been retroactively adjusted to reflect this Reverse Stock Split for all periods presented. All of the share and per share amounts have been adjusted, on a retroactive basis, to reflect the Reverse Stock Split.

New accounting pronouncements

Accounting Standards Update (“ASU”) No. 2014-10 – Development Stage Entities (Topic 915); Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities, Guidance in Topic 810, Consolidation. The Financial Accounting Standards Board decided to remove the definition of development stage entity from the Master Glossary of the Accounting Standards Codification on the basis of the effects of its decisions to eliminate any special reporting requirements by development stage entities. For public business entities, the changes are effective for annual reporting periods beginning after December 15, 2014, and interim reporting periods therein. Entities are allowed to apply such guidance early for any annual reporting period or interim period for which the entity’s financial statements have not yet been issued. The Company adopted ASU No. 2014-10 during the three months ended June 30, 2014. The adoption of ASU No. 2014-10, did not have a material effect on the Company’s financial statements other than the elimination of inception-to-date reporting information in accordance with the provisions of ASU 2014-10. Prior to our adoption ASU 2014-10, we were considered in the development stage in accordance with existing generally accepted accounting principles.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The amendments in ASU 2014-09 provide for a single, principles-based model for revenue recognition that replaces the existing revenue recognition guidance. ASU 2014-09 is effective for annual and interim periods beginning on or after December 15, 2016 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. It permits the use of either a retrospective or cumulative effect transition method and early adoption is not permitted. As the Company has not generated revenues the Company has not yet selected a transition method and is in the process of evaluating the effect this standard will have on our financial statements and related disclosures.

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

As of June 30, 2014 and December 31, 2013, the carrying amounts of cash and cash equivalents, prepaid expenses and other current assets, and accounts payable approximated their estimated fair values because of the short term nature of these financial instruments. The carrying value of the Company’s credit facility and convertible notes – related parties in current and long-term liabilities approximates fair value because the Company’s interest rate yield is near current market rates available to the Company.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value are performed in a manner to maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820, Fair Value Measurements, establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

Level 1 – Quoted prices in active markets that are accessible at the market date for identical unrestricted assets or liabilities.

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs for which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

There were no liabilities measured at fair value at June 30, 2014. Liabilities measured at fair value on a recurring basis as of December 31, 2013 are as follows:


	Level 1		Level 2		Level 3		Total
December 31, 2013:
Liabilities:
Preferred Stock Warrant Liability – Series B Preferred Stock	$	—	$	—	$	3,439,059	$	3,439,059
Preferred Stock Warrant Liability – Series A Preferred Stock		—		—		79,808		79,808

Balance at end of period	$	—	$	—	$	3,518,867	$	3,518,867

The reconciliation of the Company’s liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) is as follows:

Preferred stock warrant liability – Series A Preferred Stock:


	Period Ended June 30, 2014			Year Ended December 31, 2013
Balance at beginning of period	$	79,808		$	87,600
Net exercise of Series A Warrants		(29,247	)		—
Change in fair value		(50,561	)		(7,792	)

Balance at end of period	$	—		$	79,808

Preferred stock warrant liability – Series B Preferred Stock:


	Period Ended June 30, 2014			Year Ended December 31, 2013
Balance at beginning of period	$	3,439,059		$	2,180,500
Net exercise of Series B Warrants		(1,162,118	)		—
Exercise of warrants purchase rights into Series B Warrants		—			1,793,600
Warrant liability – Series B		—			177,952
Change in fair value		(2,276,941	)		(712,993	)

Balance at end of period	$	—		$	3,439,059

The Company’s preferred stock warrant liabilities were classified as level 3 and valued using the Black-Scholes model. The fair values were derived by applying the assumptions described below. These liabilities increased or decreased each period based on the fluctuations of the fair value of the underlying preferred security.

The table below shows the inputs used by instrument to determine the fair value measurements at December 31, 2013:


	December 31, 2013
*Preferred stock warrant liability – Series A*
Expected dividend yield		0	%
Anticipated volatility		88.57	%
Estimated stock price	$	45.20
Exercise price	$	12.24
Expected life (years)		5.28
Risk free interest rate		1.75	%
*Preferred stock warrant liabilities – Series B*

Convertible Notes Payable - Related Parties

CONVERTIBLE NOTES PAYABLE – RELATED PARTIES

In October 2013, the Company issued a convertible promissory note to Domain Partners VI, L.P., a related party, in a principal amount of $170,000, which was amended in February 2014 to extend its maturity date. The amendment to the note was determined to be a modification in accordance with ASC 470, Debt, and did not result in extinguishment. The note accrued interest at a rate of 6% per annum, and was to become due and payable in June 2014 unless converted into shares of the Company’s capital stock prior to such time pursuant to its terms.

The Company recorded the difference between the current Series B Preferred Stock Conversion price and the fair value of the Series B Preferred Stock at the date of issuance, limited to the face amount of the convertible promissory note of $170,000, as a beneficial conversion feature. This is reflected as a debt discount and is being amortized to interest expense through the note’s maturity date.

Upon the Company’s Initial Public Offering in May 2014, the note automatically converted into 21,250 shares of the Company’s common stock.

Credit Facility

CREDIT FACILITY

On April 12, 2012, the Company entered into a loan and security agreement (Credit Facility) with a bank with availability in the amount of $500,000, to provide additional capital for general working capital purposes and for capital expenditures. Interest accrued from the date of each advance equal to the greater of (a) 2.75% above the prime rate then in effect per annum, or (b) 6.50% per annum. Any amounts outstanding were payable in 24 equal monthly installments of principal, plus all accrued interest, beginning on May 12, 2013 until the loan maturity date of April 13, 2015. There were no penalties for prepayment of the principal balance. The Credit Facility was subject to certain financial covenants. The interest rate since inception of this loan has been in accordance with (b) above, 6.50%. In conjunction with obtaining the Credit Facility, the Company issued a warrant to purchase for 2,042 shares of Series A Preferred Stock. The warrant was valued at $88,100 on the date of issuance and recorded as a discount on the Credit Facility and is being amortized using the effective interest method through the maturity date of the Credit Facility.

During 2012, the Company received two advance payments totaling $500,000, the maximum borrowings under the Credit Facility. In accordance with this agreement, the Company was only required to make monthly interest payments until April 12, 2013, at which time the Company was to begin making monthly principal payments in a fixed amount of $20,833 plus interest.

On November 20, 2013, the Company amended its Credit Facility with the same bank. The amendment provided an additional $1.0 million of available funds under the facility. The Company received an advance payment of $1.0 million in November 2013 through a term loan. The amended Credit Facility calls for interest only payments at a 6.50% interest rate per annum from November 2013 through November 2014 for all amounts outstanding, inclusive of those amounts originally drawn during 2012 prior to the amendment, at which point, the Company is required to make principal payments of $58,160 plus interest through the maturity date of the term loans in November 2016. The Credit Facility, as amended, may have financial covenants established at a future date.

Both the original Credit Facility and the Credit Facility, as amended, are secured by all the intellectual property of the Company.

In conjunction with obtaining the amended Credit Facility, the Company issued a warrant exercisable for 9,692 shares of Series B Preferred Stock with an exercise price of $5.16 per share and a term of seven years. The warrant was valued at $177,952 and, together with the fair value of the warrant issued in connection with the original Credit Facility ($88,100), was recorded as a discount on the Credit Facility. These discounts are being amortized using the effective interest method through the current maturity date of the Credit Facility in November 2016. The amendment to the Credit Facility was determined to be a modification in accordance with ASC 470, Debt, and did not result in extinguishment.

At June 30, 2014, the Credit Facility is shown net of a debt discount of $172,889 which is being amortized using the effective interest method through the maturity date of the Credit Facility.

Income Tax Disclosure [Abstract]

Income Taxes

INCOME TAXES

No provision for federal taxes has been recorded as the Company has incurred losses since inception for tax purposes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

In assessing the realizability of net deferred taxes in accordance with ASC 740, Income Taxes, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on the weight of available evidence, primarily the incurrence of net losses since inception and anticipated net losses in the near future, the Company does not consider it more likely than not that some or all of the net deferred taxes will be realized. Accordingly, a 100% valuation allowance has been applied against net deferred taxes.

Under the provisions of the Internal Revenue Code, certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating loss carryforwards which can be used in future years.

All tax years are open for examination by the taxing authorities for both federal and state purposes.

The Company accounts for uncertain tax positions pursuant to ASC 740 which prescribes a recognition threshold and measurement process for financial statement recognition of uncertain tax positions taken or expected to be taken in a tax return. If the tax position meets this threshold, the benefit to be recognized is measured as the tax benefit having the highest likelihood of being realized upon ultimate settlement with the taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes. Management is not aware of any uncertain tax positions.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

STOCK INCENTIVE PLAN

The Company has three incentive plans. One was adopted in 2004 (2004 Plan) and provided for the granting of stock options and restricted stock awards to employees, board members and consultants and generally prescribed a contractual term of seven years. The 2004 Plan terminated in August 2010. However, grants made under the 2004 Plan are still governed by that plan. As of June 30, 2014, options to purchase 23,954 shares of common stock at an exercise price of $3.24 per share remained outstanding under the 2004 Plan.

The Company approved the 2010 Employee, Director and Consultant Equity Incentive Plan (2010 Plan) in September 2010 to replace the 2004 Plan. The 2010 Plan provided for the granting of stock options and restricted stock awards to certain employees, members of the board of directors and consultants of the Company. As of June 30, 2014, the number of shares of common stock authorized for issuance in connection with the 2010 Plan was 681,788.

The 2010 Plan terminated upon the Initial Public Offering. However, grants made under the 2010 Plan are still governed by that plan.

The Company approved the 2013 Equity Incentive Plan (2013 Plan) in October 2013. The 2013 Plan became effective immediately on adoption although no awards were to be made under it until the effective date of the Registration Statement for the Initial Public Offering. The 2013 Plan provides for the granting of stock options, restricted stock, stock appreciation rights, stock units, and performance cash awards to certain employees, members of the board of directors and consultants of the Company. As of June 30, 2014, the number of shares of common stock authorized for issuance in connection with the 2013 Plan was 625,000.

Options granted for the year ended December 31, 2013 include two grants of options exercisable for a total of 32,014 common shares for which vesting is contingent on certain performance conditions. For options granted containing performance conditions, the fair value is determined on the date of grant. For the three and six months ended June 30, 2014, there was $340,372 expense recorded relating to the options as the performance conditions were satisfied in May 2014.

There were stock options outstanding to purchase an aggregate of 764,990 shares of common stock at June 30, 2014 with a weighted average exercise price per share of $2.80 and stock options to purchase an aggregate of 609,842 shares of common stock outstanding at December 31, 2013 with a weighted average exercise price per share of $1.48.

In November 2013, the Company entered into a letter agreement with each of its CEO and Chief Operating Officer (COO) that became effective on the effective date of the Initial Public Offering. The letter agreements were subsequently amended in February 2014. Pursuant to these letter agreements, if the Company terminates the employment of its CEO or COO without cause or if such executive resigns for good reason, then he will be eligible to receive: continued payment of base salary for 12 months; a lump-sum cash payment equal to the greater of such executive’s target bonus for the year in which such termination occurs or the actual bonus paid to the executive with respect to our most recently completed fiscal year; payment by the Company of the monthly premiums under COBRA for such executive and their eligible dependents for up to 12 months following the termination of such executive’s employment; and accelerated vesting and exercisability with respect to all equity or equity-based awards held by such executive officer as if such executive officer has completed an additional 12 months of service with the Company, and up to 12 months following such termination to exercise any then-outstanding stock options or stock appreciation rights. Such payments are contingent on the officer’s executing and not revoking a release of claims against the Company. As of June 30, 2014 and December 31, 2013, the Company assessed the likelihood for these events to occur and has determined that a liability related to these agreements is not likely to occur and therefore has not been recorded.

In June 2014, the Company entered into a letter agreement with its CFO. Pursuant to the letter agreements, if the Company terminates the employment of its CFO without cause or if such executive resigns for good reason, then he will be eligible to receive: continued payment of base salary for 9 months; a lump-sum cash payment equal to the greater of such executive’s target bonus for the year in which such termination occurs or the actual bonus paid to the executive with respect to our most recently completed fiscal year; payment by the Company of the monthly premiums under COBRA for such executive and their eligible dependents for up to 9 months following the termination of such executive’s employment; and accelerated vesting and exercisability with respect to all equity or equity-based awards held by such executive officer as if such executive officer has completed an additional 12 months of service with the Company, and up to 12 months following such termination to exercise any then-outstanding stock options or stock appreciation rights. Such payments are contingent on the officer’s executing and not revoking a release of claims against the Company. As of June 30, 2014, the Company assessed the likelihood for these events to occur and has determined that a liability related to these agreements is not likely to occur and therefore has not been recorded.

Convertible Promissory Note – In October 2013, the Company issued a convertible promissory note to Domain Partners VI, L.P., in a principal amount of $170,000, which was amended in February 2014 to extend its maturity date.

Guarantees and Indemnifications – As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The term of the indemnification is for the officer’s or director’s lifetime. Through June 30, 2014, the Company had not experienced any losses related to these indemnification obligations and no material claims were outstanding. The Company does not expect significant claims related to these indemnification obligations, and consequently, concluded that the fair value of these obligations is negligible, and no related reserves were established.

Other Contractual Arrangements – In February 2010, the Company entered into a license and supply agreement providing the Company with an exclusive license to certain technology and access to purchase materials at certain costs. Under the terms of the license and supply agreement, the Company is obligated to make milestone payments up to an aggregate of $2.15 million upon reaching certain development and regulatory milestones in the development of the Company’s product. Upon commercialization of the Company’s product containing the licensed technology, the Company would be obligated to pay royalties based on net sales subject to an annual cap. The license and supply agreement runs through the 7th anniversary of the expiration of all patents licensed under the agreement, which the Company estimates to be April 2036, unless terminated earlier.

Basis of Presentation (Policies)	Jun. 30, 2014
Accounting Policies [Abstract]
Use of estimates	*Use of estimates* The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Reverse stock split	*Reverse stock split* On January 23, 2014, the Company’s board of directors and stockholders approved an amendment to the restated certificate of incorporation to effect a one-for-twelve reverse stock split of the Company’s common stock, options for common stock, convertible preferred stock, and warrants for convertible preferred stock which became effective on May 1, 2014, prior to the effectiveness of the Registration Statement (the Reverse Stock Split). The par value and the authorized shares of the common and convertible preferred stock were not adjusted as a result of the Reverse Stock Split. All issued and outstanding common stock, options for common stock, convertible preferred stock, and rights and warrants for convertible preferred stock, as well as the exercise price of each option for common stock, each right and each warrant for convertible preferred stock, and each right for warrants for convertible preferred stock and the conversion price for convertible preferred stock, have been retroactively adjusted to reflect this Reverse Stock Split for all periods presented. All of the share and per share amounts have been adjusted, on a retroactive basis, to reflect the Reverse Stock Split.
New accounting pronouncements	*New accounting pronouncements* *Accounting Standards Update (“ASU”) No. 2014-10* – Development Stage Entities (Topic 915); Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities, Guidance in Topic 810, Consolidation. The Financial Accounting Standards Board decided to remove the definition of development stage entity from the Master Glossary of the Accounting Standards Codification on the basis of the effects of its decisions to eliminate any special reporting requirements by development stage entities. For public business entities, the changes are effective for annual reporting periods beginning after December 15, 2014, and interim reporting periods therein. Entities are allowed to apply such guidance early for any annual reporting period or interim period for which the entity’s financial statements have not yet been issued. The Company adopted ASU No. 2014-10 during the three months ended June 30, 2014. The adoption of ASU No. 2014-10, did not have a material effect on the Company’s financial statements other than the elimination of inception-to-date reporting information in accordance with the provisions of ASU 2014-10. Prior to our adoption ASU 2014-10, we were considered in the development stage in accordance with existing generally accepted accounting principles. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The amendments in ASU 2014-09 provide for a single, principles-based model for revenue recognition that replaces the existing revenue recognition guidance. ASU 2014-09 is effective for annual and interim periods beginning on or after December 15, 2016 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. It permits the use of either a retrospective or cumulative effect transition method and early adoption is not permitted. As the Company has not generated revenues the Company has not yet selected a transition method and is in the process of evaluating the effect this standard will have on our financial statements and related disclosures.
Fair Value Measurements	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value are performed in a manner to maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820, Fair Value Measurements, establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following: Level 1 – Quoted prices in active markets that are accessible at the market date for identical unrestricted assets or liabilities. Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs for which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

- Definition

Tabular disclosure of liabilities, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, by class that are measured at fair value on a recurring basis. The disclosures contemplated herein include the fair value measurements at the reporting date by the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
