Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Formation and Business of the Company | 1. Formation and Business of the Company Aimmune Therapeutics, Inc. (“Aimmune Therapeutics” or the “Company”), formerly known as Allergen Research Corporation, is a clinical-stage biopharmaceutical company advancing a new therapeutic approach, including the development of proprietary candidates, for the treatment of peanut and other food allergies. The Company is headquartered in Brisbane, California and was incorporated in the state of Delaware on June 24, 2011. In April, 2015 the Company formed a wholly-owned subsidiary in the United Kingdom. Since inception, the Company has incurred net losses and negative cash flows from operations. During the six months ended June 30, 2015, the Company incurred a net loss of $10.8 million and used $8.8 million of cash in operations. At June 30, 2015 the Company had an accumulated deficit of $28.3 million and does not expect to experience positive cash flows in the near future. The Company has financed operations to date primarily through private placements of equity securities. The Company’s ability to continue to meet its obligations and to achieve its business objectives is dependent upon, amongst other things, raising additional capital, obtaining U.S. Food and Drug Administration (“FDA”) and European Medicines Agency (“EMA”) approval and commercializing in the United States and Europe, generating sufficient revenue and its ability to continue to control expenses, if necessary, to meet its obligations as they become due for the foreseeable future. Failure to obtain FDA and EMA approval, commercialize its lead product candidate, manage discretionary expenditures or raise additional financing, as required, may adversely impact the Company’s ability to achieve its intended business objectives. Initial Public Offering On August 5, 2015, the Company’s registration statement on Form S-1 (File No. 333-205501) relating to its initial public offering (“IPO”) of common stock became effective. The IPO closed on August 11, 2015 at which time the Company issued 11,499,999 shares of its common stock at a price of $16 per share, which included 1,499,999 shares sold pursuant to the exercise of the underwriters’ option to purchase additional shares. The Company received approximately $168 million, net of underwriting discounts and commissions, and offering expenses. In addition, upon the Company’s IPO, all outstanding shares of convertible preferred stock converted by their terms into approximately 25.1 million shares of common stock. See Note 6, “Stockholders’ Equity.” Stock Split On July 30, 2015, the Company effected a 1-for-1.317 stock split of the Company’s common stock and convertible preferred stock. The par value of the authorized stock was not adjusted as a result of the stock split. In addition, the Company increased the number of authorized shares of common stock to 55,051,264 and the number of authorized shares of preferred stock to 25,051,264. All issued and outstanding common stock, convertible preferred stock, stock options and per share amounts contained in the accompanying condensed consolidated financial statements and notes to the condensed consolidated financial statements have been retroactively adjusted to give effect to the stock split for all periods presented. In conjunction with the Company’s IPO, the Company filed its amended and restated certificate of incorporation that authorizes 290,000,000 shares of common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.0001 par value per share. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Preparation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2014 has been derived from audited consolidated financial statements at that date but does not include all of the information required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements have been prepared on the same basis as our annual financial statements and, in the opinion of management, reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair presentation of our financial information. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the year ending December 31, 2015 or for any other interim period or for any other future year. The company operates in one reportable segment. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2014 included in our Registration Statement on Form S-1 filed with the SEC. Basis of Consolidation The accompanying condensed consolidated financial statements of the Company include the accounts of its wholly-owned subsidiary. All significant intercompany transactions have been eliminated. Use of Estimates The preparation of the accompanying condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of costs and expenses during the reporting period. The Company bases its estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. The Company evaluates its estimates and assumptions on an ongoing basis. The Company’s actual results could differ from these estimates under different assumptions or conditions. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less from the date of purchase to be cash equivalents. Cash equivalents consist primarily of amounts invested in a bank high yield savings account. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company’s cash and cash equivalents are held primarily in one large financial institution in the United States. Management believes that this financial institution is financially sound, and accordingly, minimal credit risk exists with respect to this financial institution. The Company is exposed to credit risk in the event of default by the financial institution holding its cash and cash equivalents to the extent recorded on the balance sheets. Fair Value Measurement The carrying amounts of certain financial instruments, including cash and cash equivalents, restricted cash, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities. Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Maintenance and repairs are charged to operations as incurred. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss, if any, is reflected in operations. The useful lives of property and equipment are as follows: Furniture and office equipment 4 years Computer equipment 3 years Buildings 25 years Fixtures 10 years Impairment of Long-Lived Assets The Company evaluates its long-lived assets, including property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amount of each asset to the future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired assets. The Company has not recorded impairment of any long-lived assets in the periods presented. Leases The Company entered into lease agreements for its corporate headquarters and research facility in San Mateo, California through July 2017. In March 2015, the Company entered into a new lease for its corporate headquarters and research facility in Brisbane, California. In May 2015, the Company ceased use of its San Mateo facility and moved into its new facility. These leases are classified as operating leases. Rent expense is recognized on a straight-line basis over the terms of the leases and, accordingly, the Company records the difference between cash rent payments and the recognition of rent expense as a deferred rent liability. Incentives granted under the Company’s facilities leases are deferred and recognized as adjustments to rental expense on a straight-line basis over the term of the lease. In June 2015, the Company signed a new facility lease for a manufacturing facility in Clearwater, Florida. The Company was considered the deemed owner for accounting purposes. See Note 5, “Commitments and Contingencies.” Research and Development The Company expenses research and development costs as incurred. The Company records accrued liabilities for estimated costs of research and development activities conducted by third-party service providers, which include the conduct of pre-clinical studies and clinical trials and contract manufacturing activities. These costs are a significant component of the Company’s research and development expenses. The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established with its third-party service providers under the service agreements. The Company makes significant judgments and estimates in determining the accrued liabilities balance in each reporting period. As actual costs become known, the Company adjusts its accrued liabilities. The Company has not experienced any material differences between accrued costs and actual costs incurred. However, the status and timing of actual services performed, number of patients enrolled and the rate of patient enrollments may vary from the Company’s estimates, resulting in adjustments to expense in future periods. Changes in these estimates that result in material changes to the Company’s accruals could materially affect the Company’s results of operations. Stock-based Compensation Stock-based awards issued to employees, including stock options, are measured at fair value on the grant date using the Black-Scholes option-pricing model and recognized as expense on a straight-line basis over the employee’s requisite service period (generally the vesting period). Because noncash stock compensation expense is based on awards ultimately expected to vest, it is reduced by an estimate for future forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from estimates. There were 2,690,230 and 0 stock options granted during the six months ended June 30, 2015 and 2014, respectively. Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of reported 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 Company must then assess the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s lack of earnings history, the net deferred tax assets have been fully offset by a valuation allowance. The Company has adopted Financial Accounted Standards Board Accounting Standards Codification 740, Income Taxes, regarding how uncertain tax positions should be recognized, measured, presented, and disclosed in the financial statements. As of June 30, 2015 and Comprehensive Income or Loss Comprehensive income or loss is defined as the change in equity during a period from transactions and other events, excluding changes resulting from investments from owners and distributions to owners. The Company currently has no components of Comprehensive Income or Loss other than net income, therefore no separate statement of comprehensive income is presented. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Auditing Standards Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606) In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 3. Fair Value Measurements The carrying amounts of certain of the Company’s financial instruments, including cash equivalents and accounts payable approximated their fair values due to their short maturities. Assets and liabilities recorded at fair value on a recurring basis in the balance sheets, as well as assets and liabilities measured at fair value on a non-recurring basis or disclosed at fair value, are categorized based upon the level of judgment associated with inputs used to measure their fair values. The accounting guidance for fair value provide a framework for measuring fair value, and requires certain disclosures about how fair value is determined. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance also establishes a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. The three-level hierarchy for the inputs to valuation techniques is briefly summarized as follows: Level 1 —Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date; Level 2 —Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and Level 3 —Unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data. The following table sets forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands): June 30, 2015 (unaudited) Level 1 Level 2 Level 3 Total Cash and cash equivalents $ 58,502 $ — $ — $ 58,502 December 31, 2014 Level 1 Level 2 Level 3 Total Cash and cash equivalents $ 2,269 $ — $ — $ 2,269 |

Commitments and Contingencies | 5. Commitments and Contingencies Facility Leases In July 2013, the Company entered into a 48-month lease for its corporate headquarters and research facility in San Mateo, California. In July 2014, the Company entered into a second lease that expanded the space and was for a term of 36 months beginning in July 2014 and coterminous with the first lease. Under both leases, the Company paid base rent plus the tenant’s proportionate share of estimated basic operating cost as defined in the leases. The leases required a $25,000 security deposit for the duration of the leases. Rent expense under operating leases for the three months ended June 30, 2015 and and $24,000, and $49,000, term New Facility Leases In March 2015, the Company signed a new facility lease for its corporate headquarters and research facility in Brisbane, California. The new lease, which has been classified as an operating lease, commenced on May 1, 2015 with an initial term of 51 months. The Company has the right to extend the lease term for an additional 3 years at the greater of the then current base rent or the then prevailing market rent, as defined by the Renewal Option contained in the lease. The agreement required a security deposit of $85,000. The new lease calls for future aggregate minimum noncancelable lease payments as of May 1, 2015 (the inception of the lease) as follows (in thousands): Year Ended December 31, 2015 $ 190 2016 464 2017 478 2018 492 and after 294 Total $ 1,918 The Company is responsible for operating expenses over base operating expenses as defined in the headquarters lease agreement.

Purchase Commitments The Company purchases peanut flour, the source material for AR101, from the Golden Peanut Company pursuant to a long term exclusive commercial supply agreement. Pursuant to the agreement, the Company’s purchase obligation commences with the first delivery of peanut flour for commercial use, which it currently anticipates will not occur prior to 2018. Assuming the Company starts its purchase obligation of peanut flour for commercial use in 2018, which is not assured, the aggregate purchase commitment under this agreement is $1.2 million over a term of five years. Indemnifications The Company indemnifies each of its officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was serving at the Company’s request in such capacity, as permitted under Delaware law and in accordance with its certificate of incorporation and bylaws. The term of the indemnification period lasts as long as an officer or a director may be subject to any proceeding arising out of acts or omissions of such officer or director in such capacity. The maximum amount of potential future indemnification is unlimited; however, the Company currently holds director and officer liability insurance. This insurance allows the transfer of risk associated with the Company’s exposure and may enable it to recover a portion of any future amounts paid. The Company believes that the fair value of these indemnification obligations is minimal. Accordingly, it has not recognized any liabilities relating to these obligations for any period. Legal During the normal course of business, the Company may be a party to legal claims that may not be covered by insurance. Management does not believe that any such claims would have a material impact on the Company’s consolidated financial statements. |

Stock-based Awards | 7. Stock-based Awards In January 2013, the Company adopted its Stock Plan (the “Plan”). Under the Plan, shares of the Company’s common stock have been reserved for the issuance of stock options and restricted stock to employees, directors, and consultants under terms and provisions established by the Board of Directors and approved by the Company’s stockholders. At June 30, 2015 and and 639,625 and th th The Plan allows employees to exercise a stock option in exchange for stock before the requisite service is provided (e.g., before the award is vested under its original terms); however, such arrangements permit the Company to subsequently repurchase such shares at the exercise price if the vesting conditions are not satisfied. Such an exercise is not substantive for accounting purposes. Therefore, the payment received by the Company for the exercise price is recognized as an early exercise liability on the balance sheets and will be transferred to common stock and additional paid-in capital as such shares vest. At June 30, 2015 and Activity under the Plan is set forth below: Options Outstanding Shares Available for Grant Number and Unvested Shares Weighted- Average Exercise Price Weighted Average Remaining Contractual Life (in years) Balance, December 31, 2014 639,625 2,566,559 $ 0.14 9.19 Additional shares authorized 3,226,650 Options granted (2,690,230 ) 2,690,230 $ 3.02 Options exercised and shares vested (1,372,129 ) $ 0.14 Options repurchased 211,793 (211,793 ) $ 0.14 Options cancelled — — Balances – June 30, 2015 1,387,838 3,672,867 $ 2.25 9.75 Options vested and expected to vest as of June 30, 2015 (unaudited) 3,328,871 $ 1.61 9.51 Options exercisable as of June 30, 2015 (unaudited) 2,810,912 $ 2.83 9.75 The aggregate intrinsic values of options outstanding, exercisable, and vested and expected to vest were calculated as the difference between the exercise price of the options and the estimated value of the Company common stock as determined by the Company’s Board of Directors as of December 31, 2014. The Plan provides for early exercise, therefore, all the Company’s outstanding stock options are exercisable. Stock Options Granted to Employees The Company did not issue any stock options during the three and six months ended June 30, 2014. Stock options granted during the three months and six months ended June 30, 2015 had a weighted-average grant-date fair value of $4.81. The fair value is being expensed over the vesting period of the options, which is either four years or two years on a straight-line basis as the services are being provided. No tax benefits were realized from options during the periods. As of June 30, 2015 and and $120,000, The fair value of employee stock options was estimated using the Black-Scholes pricing model, with the following weighted-average assumptions (unaudited): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Expected volatility 75.77 % N/A 75.77 % N/A Risk free interest rate 1.69 % N/A 1.69 % N/A Divided yield — N/A — N/A Expected term (in years) 6.00 N/A 6.00 N/A Determining Fair Value of Stock Options The fair value of each grant of stock options was determined by the Company using the methods and assumptions discussed below. The determination of each of these inputs is subjective and generally requires significant judgment. Expected volatility —The expected stock price volatility assumption was determined by examining the historical volatilities of a group of industry peers, as the Company did not have any trading history for the Company’s common stock. The Company will continue to analyze the historical stock price volatility and expected term assumptions as more historical data for the Company’s common stock becomes available. Expected term —The expected term of stock options represents the weighted average period the stock options are expected to be outstanding. The Company’s option grants are considered “plain vanilla.” Therefore, the Company has opted to use the simplified method for estimating the expected term as provided by the Securities and Exchange Commission. The simplified method calculates the expected term as the average time- to-vesting and the contractual life of the options. Expected dividend —The expected dividend assumption was based on the Company’s history and expectation that it will not declare dividend payout for the near future. Risk-free interest rate —The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected terms. Fair value of common stock —The fair value of the shares of common stock underlying the stock options has historically been the responsibility of and determined by the Company’s board of directors. Because there has been no public market for the Company’s common stock, the board of directors determined fair value of common stock at the time of grant of the option by considering a number of objective and subjective factors including independent third-party valuations of the Company’s common stock, sales of convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of capital stock and general and industry specific economic outlook, amongst other factors. The fair value of the underlying common stock will be determined by the Company’s board of directors until such time as the Company’s common stock is listed on an established exchange or national market system. For grants during the three months ended June 30, 2015, the Company utilized a higher fair market value, for which the increase was attributed to an increased likelihood of a public offering during the period. Stock-based compensation expense, net of estimated forfeitures, is reflected in the statements of operations (in thousands, unaudited): Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 Research and development $ 88 $ 4 $ 96 $ 9 General and administrative 875 11 893 22 Total stock-based compensation expense $ 963 $ 15 $ 989 $ 31 During the three and six months ended June 30, 2015, the Company recorded approximately $562,000 of stock compensation expense related to the acceleration of certain former executives’ stock options. |

Subsequent Events [Abstract] | |
Subsequent Events | 9. Subsequent Events Income Taxes In July 2015, the Company formed a wholly-owned foreign subsidiary to which the Company licensed certain intangible rights. The Company expects that 2015 recognized revenue in the U.S., if any, as a result of this transaction will be fully offset by prior year NOLs and current year expenses. For US tax purposes, the Company expects to recognize revenue from the license in future years, in the form of royalties, if any are received in such years. Stock-based Compensation In July 2015, the Company adopted a new stock plan (“the 2015 Plan”). Under the 2015 plan, shares Facility Lease Amendment In August 2015, the Company entered into an amendment for its existing corporate headquarters and research facility in Brisbane, California. Pursuant to the amendment, the Company will lease additional office space. The term for the new space is 72 months from the delivery of the premises to the Company, which is expected to occur near the end of 2015. In addition, the term of the existing office space has been extended so that it is coterminous with the new space. As of the commencement of the amendment, future aggregate minimum lease payments for the combined space are as follows (in thousands): Year ended December 31, 2015 $ 190 2016 1,010 2017 1,602 2018 1,650 and after 5,265 Total $ 9,717 The Company is responsible for operating expenses over base operating expenses as defined in the headquarters lease agreement. |

Accounting Policies [Abstract] | |
Basis of Preparation | Basis of Preparation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2014 has been derived from audited consolidated financial statements at that date but does not include all of the information required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements have been prepared on the same basis as our annual financial statements and, in the opinion of management, reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair presentation of our financial information. The results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the year ending December 31, 2015 or for any other interim period or for any other future year. The company operates in one reportable segment. The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2014 included in our Registration Statement on Form S-1 filed with the SEC. |
Basis of Consolidation | Basis of Consolidation The accompanying condensed consolidated financial statements of the Company include the accounts of its wholly-owned subsidiary. All significant intercompany transactions have been eliminated. |
Use of Estimates | Use of Estimates The preparation of the accompanying condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of costs and expenses during the reporting period. The Company bases its estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. The Company evaluates its estimates and assumptions on an ongoing basis. The Company’s actual results could differ from these estimates under different assumptions or conditions. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less from the date of purchase to be cash equivalents. Cash equivalents consist primarily of amounts invested in a bank high yield savings account. |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company’s cash and cash equivalents are held primarily in one large financial institution in the United States. Management believes that this financial institution is financially sound, and accordingly, minimal credit risk exists with respect to this financial institution. The Company is exposed to credit risk in the event of default by the financial institution holding its cash and cash equivalents to the extent recorded on the balance sheets. |
Fair Value Measurement | Fair Value Measurement The carrying amounts of certain financial instruments, including cash and cash equivalents, restricted cash, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities. |
Property and Equipment | Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Maintenance and repairs are charged to operations as incurred. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss, if any, is reflected in operations. The useful lives of property and equipment are as follows: Furniture and office equipment 4 years Computer equipment 3 years Buildings 25 years Fixtures 10 years |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company evaluates its long-lived assets, including property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amount of each asset to the future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired assets. The Company has not recorded impairment of any long-lived assets in the periods presented. |
Leases | Leases The Company entered into lease agreements for its corporate headquarters and research facility in San Mateo, California through July 2017. In March 2015, the Company entered into a new lease for its corporate headquarters and research facility in Brisbane, California. In May 2015, the Company ceased use of its San Mateo facility and moved into its new facility. These leases are classified as operating leases. Rent expense is recognized on a straight-line basis over the terms of the leases and, accordingly, the Company records the difference between cash rent payments and the recognition of rent expense as a deferred rent liability. Incentives granted under the Company’s facilities leases are deferred and recognized as adjustments to rental expense on a straight-line basis over the term of the lease. In June 2015, the Company signed a new facility lease for a manufacturing facility in Clearwater, Florida. The Company was considered the deemed owner for accounting purposes. See Note 5, “Commitments and Contingencies.” |
Research and Development | Research and Development The Company expenses research and development costs as incurred. The Company records accrued liabilities for estimated costs of research and development activities conducted by third-party service providers, which include the conduct of pre-clinical studies and clinical trials and contract manufacturing activities. These costs are a significant component of the Company’s research and development expenses. The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established with its third-party service providers under the service agreements. The Company makes significant judgments and estimates in determining the accrued liabilities balance in each reporting period. As actual costs become known, the Company adjusts its accrued liabilities. The Company has not experienced any material differences between accrued costs and actual costs incurred. However, the status and timing of actual services performed, number of patients enrolled and the rate of patient enrollments may vary from the Company’s estimates, resulting in adjustments to expense in future periods. Changes in these estimates that result in material changes to the Company’s accruals could materially affect the Company’s results of operations. |
Stock-based Compensation | Stock-based Compensation Stock-based awards issued to employees, including stock options, are measured at fair value on the grant date using the Black-Scholes option-pricing model and recognized as expense on a straight-line basis over the employee’s requisite service period (generally the vesting period). Because noncash stock compensation expense is based on awards ultimately expected to vest, it is reduced by an estimate for future forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from estimates. There were 2,690,230 and 0 stock options granted during the six months ended June 30, 2015 and 2014, respectively. |
Income Taxes | Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of reported 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 Company must then assess the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s lack of earnings history, the net deferred tax assets have been fully offset by a valuation allowance. The Company has adopted Financial Accounted Standards Board Accounting Standards Codification 740, Income Taxes, regarding how uncertain tax positions should be recognized, measured, presented, and disclosed in the financial statements. As of June 30, 2015 and |
Comprehensive Income or Loss | Comprehensive Income or Loss Comprehensive income or loss is defined as the change in equity during a period from transactions and other events, excluding changes resulting from investments from owners and distributions to owners. The Company currently has no components of Comprehensive Income or Loss other than net income, therefore no separate statement of comprehensive income is presented. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Auditing Standards Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606) In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. |
