Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements as of and for the year ended December 31, 2013 and notes thereto, included in the Company’s prospectus filed with the SEC pursuant to Rule 424(b)(4) on April 14, 2014 (the “Prospectus”). The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements. In the opinion of the Company’s management, the accompanying unaudited interim consolidated financial statements contain all adjustments that are necessary to present fairly the Company’s financial position as of September 30, 2014 and the results of its operations for the three and nine months ended September 30, 2014 and 2013 and cash flows for the nine months ended September 30, 2014 and 2013. Such adjustments are of a normal and recurring nature. The results for the nine months ended September 30, 2014 are not indicative of the results for the year ending December 31, 2014, or for any future period. On April 15, 2014, the Company completed the sale of 8,500,000 shares of its common stock in its initial public offering, or the IPO, at a price to the public of $7.00 per share. On May 7, 2014 the Company completed the sale of an additional 1,069,715 shares of common stock at a price to the public of $7.00 per share under a partial exercise by the underwriters of their option to purchase additional shares of common stock. The sale of the shares to the public resulted in net proceeds to the Company of $59.9 million after deducting underwriting discounts and commissions and offering expenses payable by the Company. The Company’s board of directors and stockholders approved a 1- for-14.5074 reverse stock split of the Company’s common stock effective March 31, 2014. All share and per share amounts in the consolidated financial statements contained herein and notes thereto have been retroactively adjusted, where necessary, to give effect to this reverse stock split. In connection with the closing of the IPO, all of the Company’s outstanding redeemable convertible preferred stock and convertible notes automatically converted into shares of common stock as of April 15, 2014, resulting in the issuance by the Company of an additional 9,728,237 shares of common stock. The significant increase in shares outstanding in April 2014 is expected to impact the year-over-year comparability of the Company’s net loss per share calculations over the next year. In connection with the completion of the IPO on April 15, 2014, the Company’s outstanding warrants to purchase 1,857,226 shares of the Company’s preferred stock automatically converted into warrants to purchase an aggregate of 128,663 shares of the Company’s common stock and, as a result, the Company reclassified the warrant liability to additional paid-in capital.

Significant Accounting Policies |
There have been no material changes to the significant accounting policies previously disclosed in the Company’s Prospectus. Pending Adoption of Recent Accounting Pronouncements In August 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations in the financial statement footnotes. ASU No. 2014-15 is effective for annual reporting periods ending after December 15, 2016, and to annual and interim periods thereafter. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption of ASU No. 2014-15 on their consolidated financial statements and related disclosures. |

Earnings Per Share [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Net Loss Per Share Attributable to Common Stockholders |
Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. During periods in which the Company earns net income, the Company would allocate participating securities a proportional share of net income determined by dividing total weighted average participating securities by the sum of the total weighted average common shares and participating securities (the “two-class method”). The Company’s preferred stock participated in dividends declared by the Company and were therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted earnings per share during periods in which the Company earns net income. During periods in which the Company incurs a net loss, the Company allocates no portion of the loss to participating securities because they had no contractual obligation to share in the losses of the Company. The Company computes diluted loss per common share after giving consideration to the dilutive effect of stock options, warrants and shares of unvested restricted stock that are outstanding to the period, except where the inclusion of such nonparticipating securities would be antidilutive.
The Company has reported a net loss for all periods presented and, therefore, diluted net loss per common share is the same as basic net loss per common share. The following potentially dilutive securities that were outstanding prior to the use of the two-class method have been excluded from the computation of diluted weighted-average shares outstanding, because the inclusion of such securities would have an antidilutive impact due to the losses reported (in common stock equivalent shares):

Convertible Notes Payable to Shareholders |
In August of 2013, the Company issued convertible promissory notes in the amount of $8,824,000 to existing investors with a stated interest rate of 7%. Outstanding principal and unpaid accrued interest due under the notes were automatically converted into shares of the Company’s common stock upon the closing of the Company’s IPO on April 15, 2014 at a conversion price equal to the IPO price. In 2014, the Company issued convertible promissory notes in the original principal amount of $6,000,000 to existing investors and a convertible promissory note in the original principal amount of $2,500,000 to a new investor. All of the notes had a stated interest rate of 7%. Outstanding principal and unpaid accrued interest due under the notes were automatically converted into shares of the Company’s common stock upon the closing of the IPO on April 15, 2014, at a conversion price equal to 77.5% of the IPO price. The Company recorded a loss on the extinguishment of the notes of $2,493,000 in April 2014, which was equal to the difference between the fair value of the shares into which the notes converted and the carrying amount of the notes upon the closing of the IPO. |

Stock Option Plan |
A summary of stock option activity for employee, director and nonemployee awards under all stock option plans during the nine months ended September 30, 2014 is presented below:
The weighted-average per share grant date fair value of options granted during the three and nine months ended September 30, 2014 was $2.41 and $3.71, respectively. The Company did not grant any stock options during the three months ended September 30, 2013. The weighted-average per share grant date fair value of options granted during the nine months ended September 30, 2013 was $2.61. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model based on assumptions noted in the table below, except for the performance-based option grants. The fair value of the performance-based options were determined by utilizing a Monte Carlo model to simulate a wide range of possible future stock prices for the Company’s common stock. The Company has recorded stock-based compensation expense related to the issuance of stock option awards to employees of $272,000 and $32,000 for the three months ended September 30, 2014 and 2013, respectively, and $591,000 and $453,000 for the nine months ended September 30, 2014 and 2013, respectively. The assumptions used in the Black-Scholes option-pricing model for stock options granted to employees, and to directors in respect of board services during the three and nine months ended September 30, 2014 and the nine months ended September 30, 2013 are as follows:
The Company recorded stock-based compensation expense related to nonemployee awards of $13,000 and $14,000 for the three months ended September 30, 2014 and 2013, respectively, and $37,000 and $36,000 for the nine months ended September 30, 2014 and 2013, respectively. The compensation expense related to the nonemployee awards is included in the total stock-based compensation each year and is subject to re-measurement until the options vest. The Black-Scholes assumptions used to estimate fair value for the three and nine months ended September 30, 2014 and 2013 were as follows:
The Company did not grant any nonemployee stock option grants for the nine months ended September 30, 2014 and 2013, except for a performance award grant in the 2013 period to the Company’s board chairman for non-board related services. During the quarter ended September 30, 2014, the board of directors changed the vesting conditions of this award from performance-based vesting to time-based vesting and reduced the total number of shares subject to the stock option. As a result, the shares subject to this stock option now vest over three years, with the first third vesting on March 26, 2014. The change in vesting condition was accounted for as a modification of this stock option, which had an immaterial impact on the Company’s financial statements. |

Fair Value Measurements |
The Company’s financial instruments consist of cash equivalents, accounts payable, accrued expenses, debt obligations, and preferred stock warrants. The carrying amount of accounts payable and accrued expenses are considered a reasonable estimate of their fair value, due to the short-term maturity of these instruments. The carrying amount of debt is also considered to be a reasonable estimate of the fair value based on the short term nature of the debt and because the debt bears interest at the prevailing market rate for instruments with similar characteristics. 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. The accounting standard describes 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. A summary of the financial assets and liabilities that are measured on a recurring basis at fair value as of September 30, 2014 and December 31, 2013, is as follows:
The Company’s debt obligations are Level 2 measurements in the fair value hierarchy. The Company’s money market funds have been valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and asked prices, broker/dealer quotations, prices or yields of securities with similar characteristics, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. The Company is ultimately responsible for the consolidated financial statements and underlying estimates. Accordingly, the Company assesses the reasonableness of the valuations provided by the third-party pricing services by reviewing actual trade data, broker/dealer quotes and other similar data, which are obtained from quoted market prices or other sources. No transfers between levels have occurred during the periods presented. The reconciliation of the Company’s preferred stock warrant liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) is as follows:
The Company’s warrants were valued using the Black-Scholes option-pricing model. The following assumptions were used in the Black-Scholes option pricing model to determine the fair value of the preferred stock warrant liability:
The preferred stock warrant liability was reclassified to additional paid-in capital at its fair value in connection with the completion of the IPO on April 15, 2014. |

Investment in short-term money-market instruments (such as commercial paper, banker's acceptances, repurchase agreements, government securities, certificates of deposit, and so forth) which are highly liquid (that is, readily convertible to known amounts of cash) and so near their maturity that they present an insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify as cash equivalents by definition. Original maturity means an original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
