The Company and Basis of Presentation | |
The Company and Basis of Presentation | 1. The Company and Basis of Presentation The Company is a pharmaceutical company whose planned principal operations are focused on developing and commercializing first-in-class, oral, low-density lipoprotein cholesterol (“LDL-C”) lowering therapies for the treatment of patients with hypercholesterolemia. ETC-1002, or bempedoic acid, the Company’s lead product candidate, is an inhibitor of ATP Citrate Lyase, a well-characterized enzyme on the cholesterol biosynthesis pathway. ETC-1002 inhibits cholesterol synthesis, decreases intracellular cholesterol, up-regulates LDL-receptors, and causes increased LDL-C clearance and reduced plasma levels of LDL-C. The Company held an End-of-Phase 2 meeting with the Food and Drug Administration in August 2015. The Company intends to initiate a global long-term safety study for ETC-1002 by the end of 2015. The Company owns the exclusive worldwide rights to ETC-1002. The Company’s primary activities since incorporation have been conducting research and development activities, including nonclinical, preclinical and clinical testing, performing business and financial planning, recruiting personnel and raising capital. Accordingly, the Company has not commenced principal operations and is subject to risks and uncertainties which include the need to research, develop and clinically test potential therapeutic products; obtain regulatory approvals for its products and commercialize them, if approved; expand its management and scientific staff; and finance its operations with an ultimate goal of achieving profitable operations. The Company has sustained operating losses since inception and expects such losses to continue over the foreseeable future. Management plans to continue to fund operations through public or private equity or debt financings or through other sources, which may include collaborations with third parties. If adequate funds are not available, the Company may not be able to continue the development of its current or future product candidates, or to commercialize its current or future product candidates, if approved. On March 24, 2015, the Company completed an underwritten public offering of 2,012,500 shares of common stock, including 262,500 shares sold pursuant to the full exercise of an over-allotment option granted to the underwriters. All the shares were offered by the Company at a price to the public of $100.00 per share. The aggregate net proceeds received by the Company from the offering were $190.0 million, net of underwriting discounts and commissions and expenses payable by the Company. Basis of Presentation The accompanying condensed financial statements are unaudited and were prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“GAAP”). In the opinion of management, the Company has made all adjustments, which include only normal recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted. These condensed interim financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2014, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. The results of operations for the interim periods are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period. |

Summary of Significant Accounting Policies | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies In April 2015, the Financial Accounting Standards Board issued Accounting Standards Update 2015-03 which simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, rather than as a deferred charge. The recognition and measurement guidance for debt issuance costs are not affected by the amendment. The Company early-adopted the amendment effective January 1, 2015, which resulted in a change in the balance sheet presentation of net debt; in prior period disclosures the debt issuance costs related to the Company’s debt liability were presented on the balance sheet as deferred charges within “Other prepaid and current assets”. Upon adoption of the amended guidance, the debt issuance costs associated with the Company’s debt liability are presented on the balance sheet as a direct deduction from the carrying amount of the debt liability. Within the September 30, 2015, and December 31, 2014, balance sheets, “Long-term debt, net of discount and issuance costs” includes $0.1 million and $0.1 million, respectively, of debt issuance costs. There have been no other material changes to the significant accounting policies previously disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014. |

Debt | |
Debt | 3. Debt In June 2014, the Company entered into a loan and security agreement (the “Credit Facility”) with Oxford Finance LLC which provided for an initial borrowing of $5.0 million under the term loan (the “Term A Loan”) and additional borrowings of $15.0 million (the “Term B Loan”) at the Company’s option, for a maximum of $20.0 million. On June 30, 2014, the Company received proceeds of $5.0 million from the issuance of secured promissory notes under the Term A Loan. Upon achieving positive clinical development results in March 2015, the remaining $15.0 million under the Term B Loan became available to be drawn down, at the Company’s sole discretion, until March 31, 2015. The Company did not elect to draw down the Term B Loan as of March 31, 2015. The secured promissory notes issued under the Credit Facility are due on July 1, 2018, and are collateralized by substantially all of the Company’s personal property, other than its intellectual property. The Company is obligated to make monthly, interest-only payments on the Term A Loan until July 1, 2015, and, thereafter, to pay 36 consecutive, equal monthly installments of principal and interest from August 1, 2015, through July 1, 2018. The Term A Loan bears interest at an annual rate of 6.40%. In addition, a final payment equal to 8.0% of the Term A Loan is due upon the earlier of the maturity date or prepayment of the term loan. The Company is recognizing the final payment as interest expense using the effective interest method over the life of the Credit Facility. There are no financial covenants associated to the Credit Facility. However, so long as the Credit Facility is outstanding, there are negative covenants that limit or restrict the Company’s activities, which include limitations on incurring indebtedness, granting liens, mergers or acquisitions, dispositions of assets, making certain investments, entering into certain transactions with affiliates, paying dividends or distributions, encumbering or pledging interest in its intellectual property and certain other business transactions. Additionally, the Credit Facility also includes events of default, the occurrence and continuation of any of which provides the lenders the right to exercise remedies against the Company and the collateral securing the loans under the Credit Facility, which includes cash. These events of default include, among other things, non-payment of any amounts due under the Credit Facility, insolvency, the occurrence of a material adverse event, inaccuracy of representations and warranties, cross default to material indebtedness and a material judgment against the Company. Upon the occurrence of an event of default, all obligations under the Credit Facility shall accrue interest at a rate equal to the fixed annual rate plus five percentage points. In connection with the borrowing of the Term A Loan, the Company issued a warrant to purchase 8,230 shares of common stock at an exercise price of $15.19 (see Note 4). The warrant resulted in a debt discount of $0.1 million which is amortized into interest expense using the effective interest method over the life of the Term A Loan. In addition, the Company incurred debt issuance costs of $0.1 million in connection with the borrowing of the Term A Loan. The debt issuance costs were capitalized and included in long-term debt on the condensed balance sheet at the inception of the Term A Loan, and are amortized to interest expense using the effective interest method over the same term. As of September 30, 2015, the remaining unamortized discount and debt issuance costs associated with the debt were less than $0.1 million and $0.1 million, respectively. Estimated future principal payments due under the Credit Facility are as follows: Years Ending December 31, (in thousands) 2015 2016 2017 2018 Total $ During the three and nine months ended September 30, 2015, the Company recognized $0.1 million and $0.4 million, respectively of interest expense, and made cash interest payments of $0.1 million and $0.2 million, respectively, and principal payments of $0.3 million and $0.3 million, respectively, related to the Credit Facility. |

Warrants | |
Warrants | 4. Warrants In connection with the Credit Facility entered into in June 2014, the Company issued a warrant to purchase 8,230 shares of common stock at an exercise price of $15.19. The warrant will terminate on the earlier of June 30, 2019, and the closing of a merger or consolidation transaction in which the Company is not the surviving entity. The warrant was recorded at fair value of $0.1 million to additional paid-in capital in accordance with Accounting Standards Codification 815-10 based upon the allocation of the debt proceeds. The Company estimated the fair value of the warrant using a Black-Scholes option-pricing model, which is based, in part, upon subjective assumptions including but not limited to stock price volatility, the expected life of the warrant, the risk-free interest rate and the fair value of the common stock underlying the warrant. The Company estimates the volatility of its stock based on public company peer group historical volatility that is in line with the expected remaining life of the warrant. The risk-free interest rate is based on the U.S. Treasury zero-coupon bond for a maturity similar to the expected remaining life of the warrant. The expected remaining life of the warrant is assumed to be equivalent to its remaining contractual term. Upon the closing of the Company’s initial public offering in July 2013, all warrants exercisable for 1,940,000 shares of Series A preferred stock, at an exercise price of $1.00 per share (unadjusted for stock splits), were automatically converted into warrants exercisable for 277,690 shares of common stock, at an exercise price of $6.99 per share. As a result, the Company concluded the warrants outstanding no longer met the criteria to be classified as liabilities and were reclassified to additional paid-in capital at fair value on the date of reclassification. During the nine months ended September 30, 2015, 29,330 warrants were net exercised for 25,445 shares of the Company’s common stock. The remaining 248,360 warrants outstanding as of September 30, 2015, expire in February 2018. As of September 30, 2015, the Company had warrants outstanding that were exercisable for a total of 256,590 shares of common stock at a weighted-average exercise price of $7.25 per share. |

Fair Value Measurements | 6. Fair Value Measurements The Company follows accounting guidance that emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements are defined on a three level hierarchy: Level 1 inputs: Quoted prices for identical assets or liabilities in active markets; Level 2 inputs: Observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data; and Level 3 inputs: Unobservable inputs that are supported by little or no market activity and require the reporting entity to develop assumptions that market participants would use when pricing the asset or liability. The following table presents the Company’s financial assets and liabilities that have been measured at fair value on a recurring basis: Description Total Level 1 Level 2 Level 3 (in thousands) September 30, 2015 Assets: Money market funds $ $ $ — $ — Available-for-sale securities: Certificates of deposit — — U.S. treasury notes — — U.S. government agency securities — — Total assets at fair value $ $ $ $ — December 31, 2014 Assets: Money market funds $ $ $ — $ — Available-for-sale securities: Certificates of deposit — — U.S. treasury notes — — U.S. government agency securities — — Total assets at fair value $ $ $ $ — There were no transfers between Levels 1, 2 or 3 during the three and nine months ended September 30, 2015. |

Stock Compensation 2013 Stock Option and Incentive Plan In May 2015, the Company’s stockholders approved the amended and restated 2013 Stock Option and Incentive Plan (as amended, the “2013 Plan”) which, among other things, increased the number of shares of common stock reserved for issuance thereunder. The number of shares of common stock available for awards under the 2013 Plan was increased by 923,622 shares from 2,051,378 shares to 2,975,000 shares, plus (i) shares of common stock that are forfeited, cancelled, held back upon the exercise or settlement of an award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of common stock or otherwise terminated (other than by exercise) under the 2013 Plan and the Company’s 2008 Incentive Stock Option and Restricted Stock Plan are added back to the shares of common stock available for issuance under the 2013 Plan, and (ii) on January 1, 2016 and each January 1, thereafter, the number of shares of common stock reserved and available for issuance under the 2013 Plan will be cumulatively increased by 2.5% of the number of shares of common stock outstanding on the immediately preceding December 31, or such lesser number of shares of common stock determined by the compensation committee. The 2013 Plan provides for the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units (“RSUs”), unrestricted stock awards, cash-based awards, performance share awards and dividend equivalent rights. The Company incurs stock-based compensation expense related to stock options and RSUs. The fair value of RSUs is determined by the closing market price of the Company’s common stock on the date of grant. The fair value of stock options is calculated using a Black-Scholes option-pricing model. The Company accounts for stock-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation. Accordingly, compensation costs related to equity instruments granted are recognized over the requisite service periods of the awards on a straight-line basis at the grant-date fair value, taking into account estimated forfeitures. During the three and nine months ended September 30, 2015, the Company granted 25,000 RSUs to employees with a fair value for each outstanding RSU of $57.54. During the three and nine months ended September 30, 2015, equity compensation cost related to RSUs was less than $0.1 million. As of September 30, 2015, there was approximately $1.3 million of unrecognized compensation cost related to unvested RSUs, adjusted for forfeitures, which will be recognized over a weighted-average period of approximately 3.8 years.

Net Loss Per Common Share | 9. Net Loss Per Common Share Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, warrants for common stock, stock options and unvested restricted stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The shares outstanding at the end of the respective periods presented below were excluded from the calculation of diluted net loss per share due to their anti-dilutive effect: September 30, 2015 December 31, 2014 Warrants for common stock Common shares under option Unvested restricted stock Total potential dilutive shares |
