Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
The Company and Basis of Presentation | 1. THE COMPANY AND BASIS OF PRESENTATION Description of Business Cidara Therapeutics, Inc., or the Company, was originally incorporated in Delaware in December 2012 as K2 Therapeutics, Inc., and its name was changed to Cidara Therapeutics, Inc. in July 2014. The Company is a biotechnology company focused on the discovery, development and commercialization of novel anti-infectives. The Company’s initial product portfolio is comprised of proprietary product candidates for the treatment of serious fungal infections. On April 2, 2015, the Company’s board of directors and stockholders approved a 1-for-25.4 reverse stock split of its outstanding common stock. The accompanying financial statements and notes to the financial statements give retroactive effect to the reverse stock split for all periods presented. On April 20, 2015, the Company completed its initial public offering (“IPO”), whereby the Company sold 4,800,000 shares of common stock at a price of $16.00 per share. Proceeds from the IPO were approximately $69.3 million, net of underwriting discounts and commissions and offering costs. In connection with the IPO, the outstanding shares of the Company’s Series A convertible preferred stock (“Series A preferred”) and Series B convertible preferred stock (“Series B preferred”) automatically converted into 7,561,380 shares of common stock. Basis of Presentation The Company has a limited operating history and the sales and income potential of the Company’s business and market are unproven. The accompanying financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced net losses and negative cash flows from operating activities since its inception. At December 31, 2015, the Company had an accumulated deficit of $45.5 million. The Company expects to continue to incur net losses into the foreseeable future. Successful transition to attaining profitable operations is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. The Company plans to continue to fund its losses from operations and capital funding needs through debt and equity financing or through collaborations or partnerships with other companies. Debt or equity financing or collaborations and partnerships with other companies may not be available on a timely basis on terms acceptable to the Company, or at all. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations and future prospects. Use of Estimates—The preparation of financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. The Company evaluates its estimates and assumptions on an ongoing basis. The most significant estimates in the Company’s financial statements relate to estimating the fair value of the Company’s common shares used to account for share-based compensation and certain accruals, including those related to preclinical and clinical activities. Although the estimates are based on the Company’s knowledge of current events, comparable companies, and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions. Segment Information—Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, the Chief Executive Officer, in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business as one operating segment. |

Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||
Summary of Significant Accounting Policies | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents—The Company considers all short-term investments purchased with a maturity of three months or less when acquired to be cash equivalents. Investments Available-for-Sale— Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in accumulated other comprehensive income (loss). The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. The amortization of premiums and accretion of discounts is included in interest income. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in other income (expense). The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income. Securities with maturity dates of 12 months or less from the date of purchase are classified as short-term investments and securities with maturity dates of more than 12 months are classified as long-term investments. Property and Equipment— We carry our property and equipment at cost, which consists of lab equipment, computer equipment and software, office equipment, furniture and fixtures and leasehold improvements. Property and equipment is depreciated using the straight-line method over the estimated useful lives (generally three to seven years). Leasehold improvements are amortized over the lesser of their useful life or the remaining lease term, including any renewal periods that are deemed to be reasonably assured. Repair and maintenance costs are expensed as incurred. Concentration of Credit Risk—The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and short-term investments. Periodically, the Company maintains deposits in government insured financial institutions in excess of government insured limits. The Company invests its cash balances in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to significant credit risk. Patent Costs— The Company expenses all costs as incurred in connection with patent applications (including direct application fees, and the legal and consulting expenses related to making such applications) and such costs are included in general and administrative expenses in the accompanying statements of operations. Convertible Preferred Stock—The Company’s Series A preferred and Series B preferred were classified as temporary equity instead of stockholders’ equity (deficit) in accordance with authoritative guidance for the classification and measurement of potentially redeemable securities as the stock was conditionally redeemable at the holder’s option upon certain change in control events that were outside the Company’s control, including the liquidation, sale, or transfer of control of the Company. All of the outstanding Series A Preferred and Series B Preferred was converted to common upon the IPO in April 2015. Income Taxes—The Company follows the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740, Income Taxes, or ASC 740, in reporting deferred income taxes. The ASC 740 requires a company to recognize deferred tax assets and liabilities for expected future income tax consequences of events that have been recognized in the Company’s financial statements. Under this method, deferred tax assets and liabilities are determined based on temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in the years in which the temporary differences are expected to reverse. Valuation allowances are provided if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. 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. Research and Development Costs—Research and development expenses consist of wages, benefits and stock-based compensation charges for research and development employees, scientific consultant fees, facilities and overhead expenses, laboratory supplies, manufacturing expenses, and preclinical and clinical trial costs. The Company accrues clinical trial expenses based on work performed which relies on estimates of total costs incurred based on patient enrollment, completion of studies, and other events. Costs incurred in purchasing technology assets and intellectual property are charged to research and development expense if the technology has not been conclusively proven to be feasible and has no alternative future use. Comprehensive Loss—Comprehensive loss is defined as the change in equity during a period from transactions and other events and/or circumstances from non-owner sources. The Company’s only component of other comprehensive loss is unrealized gains (losses) on short-term marketable securities. Comprehensive gains (losses) have been reflected in the statements of operations and comprehensive loss and as a separate component of the statements of convertible preferred stock and stockholders’ equity (deficit) for all periods presented. Stock-based Compensation— The Company accounts for stock-based compensation expense related to employee stock options, restricted stock grants, and employee stock purchase plan rights by estimating the fair value on the date of grant using the Black-Scholes option pricing model. For awards subject to time-based vesting conditions, stock-based compensation expense is recognized ratably over the requisite service period of the awards, net of estimated forfeitures. The Company accounts for stock options granted to non-employees using the fair value approach. These option grants are subject to periodic revaluation over their vesting terms. Net Loss Per Share—Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Dilutive common stock equivalents are comprised of convertible preferred stock, convertible notes payable, unvested restricted common stock subject to repurchase, and options outstanding under the Company’s stock option plan. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding. The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because to do so would be anti-dilutive (in common stock equivalent shares):
Fair Value of Financial Instruments— The Company follows authoritative guidance with respect to fair value reporting issued by the FASB for financial assets and liabilities, which defines fair value, provides guidance for measuring fair value and requires certain disclosures. The guidance does not apply to measurements related to share-based payments. The guidance discusses valuation techniques such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The Company’s financial instruments consist of cash and cash equivalents, marketable securities, prepaid expenses, accounts payable, and accrued liabilities. Fair value estimates of these instruments are made at a specific point in time based on relevant market information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. The carrying amount of cash and cash equivalents, prepaid expenses, accounts payable, and accrued liabilities are generally considered to be representative of their respective fair values because of the short-term nature of those instruments. The fair value of marketable securities is based upon market prices quoted on the last day of the fiscal period or other observable market inputs. Recently Issued Accounting Standards— During 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements—Going Concern.” The update requires management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosure in certain circumstances. The update is effective for annual reporting periods ending after December 15, 2016 and interim periods thereafter. Early application is permitted. The Company is currently assessing the impact that this standard will have on its financial statements. During 2015, the FASB issued ASU 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes,” which amends existing guidance to require companies to classify deferred tax assets and liabilities as noncurrent in the statement of financial position. The update is effective for annual periods beginning after December 15, 2016, and early adoption is permitted. The update may be adopted on either a prospective or retrospective basis. The Company adopted ASU 2015-17 in the fourth quarter of 2015 on a retrospective basis. The adoption of this guidance did not have a material impact on the Company’s financial statements. During 2016, the FASB issued ASU 2016-02, “Leases,” which requires that lease arrangements longer than 12 months result in an entity recognizing an asset and liability. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently assessing the impact that this standard will have on its financial statements. |

Fair Value Measurements | 4. FAIR VALUE MEASUREMENTS The Company follows ASC 820-10, Fair Value Measurements and Disclosures, which among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions, which reflect those that a market participant would use. At December 31, 2015, the Company held certificates of deposit, which are valued at cost, and commercial paper, which is valued using observable market inputs including reported trades, broker/dealer quotes, bids and/or offers. At December 31, 2015 and 2014, the Company held securities of a money market fund which invested in short-term U.S. Treasury securities, the prices of which were available from quoted prices in active markets. None of the Company’s non-financial assets or liabilities are recorded at fair value on a non-recurring basis. No transfers between levels have occurred during the periods presented. The following tables summarize the Company’s financial instruments measured at fair value on a recurring basis:

Debt | 6. DEBT 2013 Convertible Notes Payable During 2013, the Company issued convertible notes (the 2013 Notes) to a major shareholder of the Company, 5AM Ventures, for an aggregate of $1,250,000. The 2013 Notes bore interest at 8%, which compounded annually.

Equity Incentive Plans | 8. EQUITY INCENTIVE PLANS 2015 Equity Incentive Plan In March 2015, the Company’s board of directors and stockholders approved and adopted the 2015 Equity Incentive Plan (“2015 EIP”). Under the 2015 EIP, the Company may grant stock options, stock appreciation rights, restricted stock, restricted stock units, and other awards to individuals who are employees, officers, directors, or consultants of the Company. A total of 1,829,020 shares of common stock were reserved for issuance under the 2015 EIP. The number of shares of stock available for issuance under the 2015 EIP will be automatically increased each January 1, beginning on January 1, 2016, by 4% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31 or such lesser number as determined by the Company’s board of directors. Terms of stock award agreements, including vesting requirements, are determined by the board of directors, subject to the provisions of the 2015 EIP. Stock options granted by the Company generally vest over a three- or four-year year period. Certain stock options are subject to acceleration of vesting in the event of certain change of control transactions. The stock options may be granted for a term of up to ten years from the date of grant. The exercise price for stock options granted under the 2015 EIP must be at a price no less than 100% of the estimated fair value of the shares on the date of grant as determined by the board of directors, provided that for an incentive stock option granted to an employee who at the time of grant owns stock representing more than 10% of the voting power of all classes of stock of the Company, the exercise price shall be no less than 110% of the estimated value on the date of grant. As of December 31, 2015, the Company had 1,788,396 shares available for future issuance to employees, nonemployee directors, and consultants of the Company under the 2015 EIP. 2015 Employee Stock Purchase Plan In March 2015, the Company’s board of directors and stockholders approved and adopted the 2015 Employee Stock Purchase Plan (“ESPP”). A total of 245,168 shares of common stock were initially reserved for issuance under the ESPP. In addition, the number of shares of stock available for issuance under the ESPP will be automatically increased each January 1, beginning on January 1, 2016, by the lesser of (i) 1% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31, or (ii) 490,336 shares. The ESPP allows substantially all employees to purchase the Company’s common stock through a payroll deduction at a price equal to 85% of the lower of the fair market value of the stock as of the beginning or the end of each purchase period. An employee’s payroll deductions under the under the ESPP are limited to 15% of the employee’s eligible compensation. During the year ended December 31, 2015, 19,164 shares were issued pursuant to the ESPP. Restricted Stock The Company permits early exercise of certain stock options. Any unvested shares are restricted and subject to repurchase by the Company until the conditions for vesting are met. At December 31, 2015 and 2014, the liabilities for the cash received from the early exercise of stock options were $341,000 and $736,000, respectively, and were classified in accrued liabilities on the balance sheet. The Company reduces the liability as the underlying shares vest in accordance with the vesting terms outlined in the stock option agreements which, generally, is 4 years. At December 31, 2015, 156,235 unvested shares were subject to repurchase by the Company. Stock Options The following table summarizes stock option activity during the year ended December 31, 2015:
The following table summarizes the Black-Scholes option pricing model assumptions used to estimate the fair value of stock options granted to employees under our equity incentive plans and the shares purchasable under our 2015 ESPP during the periods presented:
Stock-based compensation expense recognized for stock options and the ESPP has been reported in the statements of operations and comprehensive loss as follows (in thousands):
The weighted-average grant date fair value of stock options granted to employees during the year ended December 31, 2015 was $5.81 per share. The total grant date fair value of stock options that vested during the year ended December 31, 2015 was $2.2 million. As of December 31, 2015, total unrecognized share-based compensation expense related to unvested employee stock options of the Company was approximately $4.7 million. This unrecognized compensation cost is expected to be recognized over a weighted-average period of approximately 2.7 years. As of December 31, 2015, total unrecognized compensation expense related to the Company’s ESPP was approximately $0.5 million. This unrecognized compensation cost is expected to be recognized over approximately 1.9 years.

Income Tax Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Income Taxes | 9. INCOME TAXES The Company accounts for income taxes under ASC 740. Deferred income tax assets and liabilities are determined based upon differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The following table provides a reconciliation between income taxes computed at the federal statutory rate of 34% and the provision for income taxes (in thousands):
Significant components of the Company’s net deferred tax assets are as follows (in thousands):
At December 31, 2015, the Company had federal and state net operating loss carryforwards of approximately $39.3 million and $39.4 million, respectively. The federal and state loss carryforwards begin to expire in 2033, unless previously utilized. The Company also has federal and state research and development credit carryforwards totaling $1.0 million and $0.5 million, respectively. The federal research and development credit carryforwards begin to expire in 2033, unless previously utilized. The state research and development credit carryforwards begin to expire in 2028. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. Based on the weight of all evidence, including a history of operating losses, management has determined that it is more likely than not that the net deferred tax assets will not be realized. A valuation allowance of $18.5 million and $5.3 million as of December 31, 2015 and 2014, respectively, has been established to offset the deferred tax assets as realization of such assets is uncertain. Future utilization of the Company’s net operating loss and research and development credits carryforwards to offset future taxable income may be subject to an annual limitation, pursuant to Internal Revenue Code (IRC) Sections 382 and 383, as a result of ownership changes that may have occurred or that could occur in the future. An ownership change occurs when a cumulative change in ownership of more than 50% occurs within a three-year period. The Company has not completed an IRC Section 382/383 analysis regarding the limitation of net operating loss and research and development credit carryforwards. The Company recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition at the effective date to be recognized. At December 31, 2015 and 2014, the unrecognized tax benefits recorded were approximately $356,000 and $108,000, respectively. Approximately $318,000 and $94,000 of the unrecognized tax benefits for the years ended December 31, 2015 and 2014, respectively, would reduce our annual effective tax rates, if recognized, subject to the valuation allowances. The Company does not anticipate a significant change in the unrecognized tax benefits within the next 12 months. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits for 2015, 2014 and 2013 is as follows (in thousands):
The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by the United States and state jurisdictions where applicable. There are currently no pending income tax examinations. The Company’s tax years from inception in 2012 are subject to examination by the federal and state tax authorities due to the carryforward of unutilized net operating losses and research and development credits. The Company’s practice is to recognize interest and penalties related to income tax matters in income tax expense. The Company has not recognized interest or penalties since inception. |

Dec. 31, 2015 | |||||||||||||||||||||||||||||||||||||||||||||||||
Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||
Basis of Presentation | Basis of Presentation The Company has a limited operating history and the sales and income potential of the Company’s business and market are unproven. The accompanying financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced net losses and negative cash flows from operating activities since its inception. At December 31, 2015, the Company had an accumulated deficit of $45.5 million. The Company expects to continue to incur net losses into the foreseeable future. Successful transition to attaining profitable operations is dependent upon achieving a level of revenues adequate to support the Company’s cost structure. The Company plans to continue to fund its losses from operations and capital funding needs through debt and equity financing or through collaborations or partnerships with other companies. Debt or equity financing or collaborations and partnerships with other companies may not be available on a timely basis on terms acceptable to the Company, or at all. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations and future prospects. |
||||||||||||||||||||||||||||||||||||||||||||||||
Use of Estimates | Use of Estimates—The preparation of financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. The Company evaluates its estimates and assumptions on an ongoing basis. The most significant estimates in the Company’s financial statements relate to estimating the fair value of the Company’s common shares used to account for share-based compensation and certain accruals, including those related to preclinical and clinical activities. Although the estimates are based on the Company’s knowledge of current events, comparable companies, and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions. |
||||||||||||||||||||||||||||||||||||||||||||||||
Segment Information | Segment Information—Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, the Chief Executive Officer, in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business as one operating segment. |
||||||||||||||||||||||||||||||||||||||||||||||||
Cash and Cash Equivalents | Cash and Cash Equivalents—The Company considers all short-term investments purchased with a maturity of three months or less when acquired to be cash equivalents. |
||||||||||||||||||||||||||||||||||||||||||||||||
Investments Available-for-Sale | Investments Available-for-Sale— Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in accumulated other comprehensive income (loss). The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. The amortization of premiums and accretion of discounts is included in interest income. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in other income (expense). The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income. Securities with maturity dates of 12 months or less from the date of purchase are classified as short-term investments and securities with maturity dates of more than 12 months are classified as long-term investments. |
||||||||||||||||||||||||||||||||||||||||||||||||
Property and Equipment | Property and Equipment— We carry our property and equipment at cost, which consists of lab equipment, computer equipment and software, office equipment, furniture and fixtures and leasehold improvements. Property and equipment is depreciated using the straight-line method over the estimated useful lives (generally three to seven years). Leasehold improvements are amortized over the lesser of their useful life or the remaining lease term, including any renewal periods that are deemed to be reasonably assured. Repair and maintenance costs are expensed as incurred. |
||||||||||||||||||||||||||||||||||||||||||||||||
Concentration of Credit Risk | Concentration of Credit Risk—The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and short-term investments. Periodically, the Company maintains deposits in government insured financial institutions in excess of government insured limits. The Company invests its cash balances in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to significant credit risk. |
||||||||||||||||||||||||||||||||||||||||||||||||
Patent Costs | Patent Costs— The Company expenses all costs as incurred in connection with patent applications (including direct application fees, and the legal and consulting expenses related to making such applications) and such costs are included in general and administrative expenses in the accompanying statements of operations. |
||||||||||||||||||||||||||||||||||||||||||||||||
Convertible Preferred Stock | Convertible Preferred Stock—The Company’s Series A preferred and Series B preferred were classified as temporary equity instead of stockholders’ equity (deficit) in accordance with authoritative guidance for the classification and measurement of potentially redeemable securities as the stock was conditionally redeemable at the holder’s option upon certain change in control events that were outside the Company’s control, including the liquidation, sale, or transfer of control of the Company. All of the outstanding Series A Preferred and Series B Preferred was converted to common upon the IPO in April 2015. |
||||||||||||||||||||||||||||||||||||||||||||||||
Income Taxes | Income Taxes—The Company follows the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740, Income Taxes, or ASC 740, in reporting deferred income taxes. The ASC 740 requires a company to recognize deferred tax assets and liabilities for expected future income tax consequences of events that have been recognized in the Company’s financial statements. Under this method, deferred tax assets and liabilities are determined based on temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in the years in which the temporary differences are expected to reverse. Valuation allowances are provided if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. 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. |
||||||||||||||||||||||||||||||||||||||||||||||||
Research and Development Costs | Research and Development Costs—Research and development expenses consist of wages, benefits and stock-based compensation charges for research and development employees, scientific consultant fees, facilities and overhead expenses, laboratory supplies, manufacturing expenses, and preclinical and clinical trial costs. The Company accrues clinical trial expenses based on work performed which relies on estimates of total costs incurred based on patient enrollment, completion of studies, and other events. Costs incurred in purchasing technology assets and intellectual property are charged to research and development expense if the technology has not been conclusively proven to be feasible and has no alternative future use. |
||||||||||||||||||||||||||||||||||||||||||||||||
Comprehensive Loss | Comprehensive Loss—Comprehensive loss is defined as the change in equity during a period from transactions and other events and/or circumstances from non-owner sources. The Company’s only component of other comprehensive loss is unrealized gains (losses) on short-term marketable securities. Comprehensive gains (losses) have been reflected in the statements of operations and comprehensive loss and as a separate component of the statements of convertible preferred stock and stockholders’ equity (deficit) for all periods presented. |
||||||||||||||||||||||||||||||||||||||||||||||||
Stock-based Compensation | Stock-based Compensation— The Company accounts for stock-based compensation expense related to employee stock options, restricted stock grants, and employee stock purchase plan rights by estimating the fair value on the date of grant using the Black-Scholes option pricing model. For awards subject to time-based vesting conditions, stock-based compensation expense is recognized ratably over the requisite service period of the awards, net of estimated forfeitures. The Company accounts for stock options granted to non-employees using the fair value approach. These option grants are subject to periodic revaluation over their vesting terms. |
||||||||||||||||||||||||||||||||||||||||||||||||
Net Loss Per Share | Net Loss Per Share—Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. Dilutive common stock equivalents are comprised of convertible preferred stock, convertible notes payable, unvested restricted common stock subject to repurchase, and options outstanding under the Company’s stock option plan. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding. The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because to do so would be anti-dilutive (in common stock equivalent shares):
|
||||||||||||||||||||||||||||||||||||||||||||||||
Fair Value of Financial Instruments | Fair Value of Financial Instruments— The Company follows authoritative guidance with respect to fair value reporting issued by the FASB for financial assets and liabilities, which defines fair value, provides guidance for measuring fair value and requires certain disclosures. The guidance does not apply to measurements related to share-based payments. The guidance discusses valuation techniques such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The Company’s financial instruments consist of cash and cash equivalents, marketable securities, prepaid expenses, accounts payable, and accrued liabilities. Fair value estimates of these instruments are made at a specific point in time based on relevant market information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. The carrying amount of cash and cash equivalents, prepaid expenses, accounts payable, and accrued liabilities are generally considered to be representative of their respective fair values because of the short-term nature of those instruments. The fair value of marketable securities is based upon market prices quoted on the last day of the fiscal period or other observable market inputs. |
||||||||||||||||||||||||||||||||||||||||||||||||
Recently Issued Accounting Standards | Recently Issued Accounting Standards— During 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements—Going Concern.” The update requires management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosure in certain circumstances. The update is effective for annual reporting periods ending after December 15, 2016 and interim periods thereafter. Early application is permitted. The Company is currently assessing the impact that this standard will have on its financial statements. During 2015, the FASB issued ASU 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes,” which amends existing guidance to require companies to classify deferred tax assets and liabilities as noncurrent in the statement of financial position. The update is effective for annual periods beginning after December 15, 2016, and early adoption is permitted. The update may be adopted on either a prospective or retrospective basis. The Company adopted ASU 2015-17 in the fourth quarter of 2015 on a retrospective basis. The adoption of this guidance did not have a material impact on the Company’s financial statements. During 2016, the FASB issued ASU 2016-02, “Leases,” which requires that lease arrangements longer than 12 months result in an entity recognizing an asset and liability. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The Company is currently assessing the impact that this standard will have on its financial statements. |
