Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
The Company and Basis of Presentation | The Company and Basis of Presentation Insmed is a global biopharmaceutical company focused on the unmet needs of patients with rare diseases. The Company's lead product candidate is amikacin liposome inhalation suspension (ALIS), which is in late-stage development for adult patients with treatment refractory nontuberculous mycobacteria (NTM) lung disease caused by Mycobacterium avium complex (MAC), a rare and often chronic infection that can cause irreversible lung damage and can be fatal. Our earlier clinical-stage pipeline includes INS1007 and INS1009. INS1007 is a novel oral, reversible inhibitor of dipeptidyl peptidase 1 (DPP1), an enzyme responsible for activating neutrophil serine proteases, which are implicated in the pathology of chronic inflammatory lung diseases, such as non-cystic fibrosis (non-CF) bronchiectasis. INS1009 is an inhaled nanoparticle formulation of a treprostinil prodrug that may offer a differentiated product profile for rare pulmonary disorders, including pulmonary arterial hypertension (PAH). The Company was incorporated in the Commonwealth of Virginia on November 29, 1999 and its principal executive offices are in Bridgewater, New Jersey. The Company has legal entities in the United States (US), Ireland, Germany, France, the United Kingdom (UK), the Netherlands, and Japan. All intercompany transactions and balances have been eliminated in consolidation. The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and disclosures required by accounting principles generally accepted in the US for complete consolidated financial statements are not included herein. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . The results of operations of any interim period are not necessarily indicative of the results of operations for the full year. The unaudited interim consolidated financial information presented herein reflects all normal adjustments that are, in the opinion of management, necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The following are the required interim disclosure updates to the Company's significant accounting policies described in Note 2 of the notes to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 : Fair Value Measurements - The Company categorizes its financial assets and liabilities measured and reported at fair value in the financial statements on a recurring basis based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs used to determine the fair value of financial assets and liabilities, are as follows: • Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the assets or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Each major category of financial assets and liabilities measured at fair value on a recurring basis is categorized based upon the lowest level of significant input to the valuations. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments in Level 1 generally include US treasuries and mutual funds listed in active markets. The Company’s only financial assets and liabilities which were measured at fair value as of March 31, 2018 and December 31, 2017 were Level 1 and such assets were comprised of cash and cash equivalents of $686.6 million and $381.2 million , respectively. The Company’s cash and cash equivalents permit daily redemption and the fair values of these investments are based upon the quoted prices in active markets provided by the holding financial institutions. Cash equivalents consist of liquid investments with an original maturity of three months or less from the date of purchase. As of March 31, 2018 , the Company's cash and cash equivalents balance included US treasury bills of $180.0 million . The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers in or out of Level 1, Level 2 or Level 3 during the three months ended March 31, 2018 and 2017 , respectively. As of March 31, 2018 and December 31, 2017 , the Company held no securities that were in an unrealized gain or loss position. The Company reviews the status of each security quarterly to determine whether an other-than-temporary impairment has occurred. In making its determination, the Company considers a number of factors, including: (1) the significance of the decline; (2) whether the securities were rated below investment grade; (3) how long the securities have been in an unrealized loss position; and (4) the Company’s ability and intent to retain the investment for a sufficient period of time for it to recover. Net Loss Per Share - Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares and other dilutive securities outstanding during the period. Potentially dilutive securities from stock options, restricted stock units (RSUs) and convertible debt securities would be anti-dilutive as the Company incurred a net loss. Potentially dilutive common shares resulting from the assumed exercise of outstanding stock options are determined based on the treasury stock method. The following table sets forth the reconciliation of the weighted average number of common shares used to compute basic and diluted net loss per share for the three months ended March 31, 2018 and 2017 : Three Months Ended March 31, 2018 2017 (in thousands, except per share amounts) Numerator: Net loss $ (68,524 ) $ (37,414 ) Denominator: Weighted average common shares used in calculation of basic net loss per share: 76,619 62,041 Effect of dilutive securities: Common stock options — — RSUs — — Convertible debt securities — — Weighted average common shares outstanding used in calculation of diluted net loss per share 76,619 62,041 Net loss per share: Basic and Diluted $ (0.89 ) $ (0.60 ) The following potentially dilutive securities have been excluded from the computations of diluted weighted average common shares outstanding as of March 31, 2018 and 2017 as their effect would have been anti-dilutive (in thousands): As of March 31, 2018 2017 Stock options to purchase common stock 9,866 7,719 Unvested RSUs 234 89 Convertible debt securities 11,492 — Recently Adopted Accounting Pronouncements - In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which addressed eight specific cash flow issues with the objective of reducing the existing diversity in practice. Among the updates, the standard requires debt extinguishment costs to be classified as cash outflows for financing activities. This standard update is effective as of the first quarter of 2018. As a result of the adoption of the standard, in the first quarter of 2018, the Company reported a $2.2 million loss on extinguishment of debt in the financing activities section of its consolidated statement of cash flows. The Company had no material debt extinguishment costs prior to the first quarter of 2018. There were no other significant impacts as a result of adopting this standard. In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , which defines management’s responsibility to perform interim and annual assessments of an entity’s ability to continue as a going concern, and to provide related footnote disclosures if there is substantial doubt about its ability to continue as a going concern. The new standard was effective for the annual period ending after December 15, 2016, and for interim periods thereafter. The Company adopted ASU 2014-15 in the fourth quarter of 2016, which had no impact on the Company’s consolidated financial statements. The interim assessment during the first quarter of 2018 did not have an impact on the consolidated financial statements. The Company had $686.6 million in cash and cash equivalents as of March 31, 2018 and reported a net loss of $68.5 million for the three months ended March 31, 2018 . Historically, the Company has funded its operations through public offerings of equity securities and debt financings. To date, the Company has not generated material revenue from ALIS. The Company does not expect to generate material revenue unless or until marketing approval is received for ALIS. Accordingly, the Company expects to continue to incur losses while funding research and development (R&D) activities, regulatory submissions, potential commercial launch activities and general and administrative expenses. The Company expects its future cash requirements to be substantial, and the Company may need to raise additional capital to fund operations, to develop and commercialize ALIS, to develop INS1007 and INS1009 and to develop, acquire, in-license or co-promote other products that address orphan or rare diseases. ASU 2014-15 requires the Company to evaluate whether it has sufficient resources to fund operations for 12 months from the filing date of this Quarterly Report on Form 10-Q without regard to whether or not it can raise capital in the future. The Company believes it currently has sufficient funds to meet its financial needs for at least the next 12 months. In September 2017, the Company completed an underwritten offering of 14.1 million shares of its common stock for cash proceeds of $377.7 million , net of fees and expenses related to the offering. Further, in January 2018, the Company completed an underwritten public offering of 1.75% convertible senior notes due 2025 (the Convertible Notes) pursuant to an indenture, dated as of January 26, 2018, between the Company and Wells Fargo Bank, National Association (Wells Fargo), as trustee, as supplemented by the first supplemental indenture, dated January 26, 2018, between the Company and Wells Fargo (as supplemented, the Indenture). The Company sold $450.0 million aggregate principal amount of Convertible Notes, including the exercise in full of the underwriters' option to purchase additional Convertible Notes of $50.0 million . The Company's net proceeds from the offering, after deducting underwriting discounts and commissions and other offering expenses of $14.1 million , were approximately $435.9 million . The source, timing and availability of any future financing or other transaction will depend principally upon continued progress in the Company’s regulatory, development and pre-commercial activities. Any equity or debt financing will also be contingent upon equity and debt market conditions and interest rates at the time. If the Company is unable to obtain sufficient additional funds when required, the Company may be forced to delay, restrict or eliminate all or a portion of its R&D programs, pre-commercialization activities, or dispose of assets or technology. In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers (Topic 606) which amended the existing accounting standards for revenue recognition. ASU 2014-9 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. In July 2015, the FASB deferred the effective date for annual reporting periods beginning after December 15, 2017. The Company adopted ASU 2014-9 in the first quarter of 2018 and the impact of adoption is not material to its consolidated financial statements. New Accounting Pronouncements (Not Yet Adopted) —In February 2016, the FASB issued ASU 2016-2, Leases (Topic 842) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. ASU 2016-2 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-2 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. The Company expects to adopt ASU 2016-2 in the first quarter of 2019 and is in the process of evaluating the impact of adoption on its consolidated financial statements. |

Debt Disclosure [Abstract] | |
Debt | Debt In January 2018, the Company completed an underwritten public offering of the Convertible Notes, in which the Company sold $450.0 million aggregate principal amount of Convertible Notes, including the exercise in full of the underwriters' option to purchase additional Convertible Notes of $50.0 million . The Company's net proceeds from the offering, after deducting underwriting discounts and commissions and other offering expenses of $14.1 million , were approximately $435.9 million . The Convertible Notes bear interest payable semiannually in arrears on January 15 and July 15 of each year, beginning on July 15, 2018. The Convertible Notes mature on January 15, 2025, unless earlier converted, redeemed, or repurchased. On or after October 15, 2024, until the close of business on the second scheduled trading day immediately preceding January 15, 2025, holders may convert their Convertible Notes at any time. Upon conversion, holders may receive cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock, at the Company's option. The initial conversion rate is 25.5384 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $39.16 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. Holders may convert their Convertible Notes prior to October 15, 2024, only under certain circumstances, subject to the conditions set forth in the Indenture, including any one of the following: (i) during the five business day period immediately after any five consecutive trading day period (the measurement period) in which the trading price per $1,000 principal amount of convertible notes, as determined following a request by a holder of the convertible notes, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on such trading day, (ii) the Company elects to distribute to all or substantially all holders of the common stock (a) any rights, options or warrants (other than in connection with a stockholder rights plan for so long as the rights issued under such plan have not detached from the associated shares of common stock) entitling them, for a period of not more than 45 days from the declaration date for such distribution, to subscribe for or purchase shares of common stock at a price per share that is less than the average of the last reported sale prices of the common stock for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the declaration date for such distribution, or (b) the Company’s assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the board of directors, exceeding 10% of the last reported sale price of the common stock on the trading day immediately preceding the declaration date for such distribution, (iii) if a transaction or event that constitutes a fundamental change or a make-whole fundamental change occurs, or if the Company is a party to (a) a consolidation, merger, combination, statutory or binding share exchange or similar transaction, pursuant to which the common stock would be converted into, or exchanged for, cash, securities or other property or assets, or (b) any sale, conveyance, lease or other transfer or similar transaction in one transaction or a series of transactions of all or substantially all of the consolidated assets of the Company and its subsidiaries, taken as a whole, all or any portion of the Convertible Notes may be surrendered by a holder for conversion at any time from or after the date that is 30 scheduled trading days prior to the anticipated effective date of the transaction, (iv) if during any calendar quarter commencing after the calendar quarter ending on March 31, 2018 (and only during such calendar quarter), the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day, or, (v) if the Company sends a notice of redemption, a holder may surrender all or any portion of its Convertible Notes, to which the notice of redemption relates, for conversion at any time on or after the date the applicable notice of redemption was sent until the close of business on (a) the second business day immediately preceding the related redemption date or (b) if the Company fails to pay the redemption price on the redemption date as specified in such notice of redemption, such later date on which the redemption price is paid. The Convertible Notes can be settled in cash, common stock, or a combination of cash and common stock at the Company's option, and thus, the Company determined the embedded conversion options in the convertible notes are not required to be separately accounted for as a derivative. However, since the Convertible Notes are within the scope of the accounting guidance for cash convertible instruments, the Company is required to separate the Convertible Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated equity component. The fair value was based on data from readily available pricing sources which utilize market observable inputs and other characteristics for similar types of instruments. The carrying amount of the equity component representing the embedded conversion option was determined by deducting the fair value of the liability component from the gross proceeds of the Convertible Notes. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the expected life of a similar liability that does not have an associated equity component using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification in the accounting guidance for contracts in an entity’s own equity. The fair value of the liability component of the Convertible Notes on the date of issuance was estimated at $309.1 million using an effective interest rate of 7.6% , and accordingly, the equity component on the date of issuance was $140.9 million . The discount is being amortized to interest expense over the term of the Convertible Notes, which results in a remaining period of approximately 6.8 years. For the quarter ended March 31, 2018, total interest expense related to the Convertible Notes was $4.7 million , which includes the contractual interest coupon, the amortization of the issuance costs, and accretion of debt discount, as described in the table below. The following table presents the components of the Company’s debt balance as of March 31, 2018 (in thousands): 1.75% convertible senior notes due 2025 $ 450,000 Debt issuance costs, unamortized (9,424 ) Discount on debt (137,870 ) Long-term debt, net $ 302,706 As of March 31, 2018 , future principal repayments of the debt for each of the fiscal years through maturity were as follows (in thousands): Year Ending December 31: 2018 $ — 2019 — 2020 — 2021 — 2022 — 2023 and thereafter 450,000 $ 450,000 The estimated fair value of the liability component of the Convertible Notes (categorized as a Level 2 liability for fair value measurement purposes) was determined using current market factors and the ability of the Company to obtain debt at comparable terms to those that are currently in place. The Company believes the estimated fair value at March 31, 2018 approximates the carrying amount. In February 2018, the Company used part of the net proceeds from the issuance of the Convertible Notes to pay off its outstanding debt to Hercules Capital (Hercules). The payments to Hercules consisted of $55.0 million for the principal amount and an additional $3.2 million in back-end fees, outstanding interest, and prepayment penalty fees, which resulted in a $2.2 million loss on extinguishment of debt in the quarter ended March 31, 2018.

Stockholders' Equity Note [Abstract] | |
Shareholders' Equity | Shareholders’ Equity Common Stock — As of March 31, 2018 , the Company had 500,000,000 shares of common stock authorized with a par value of $0.01 and 76,623,136 shares of common stock issued and outstanding. In addition, as of March 31, 2018 , the Company had reserved 9,865,574 shares of common stock for issuance upon the exercise of outstanding stock options and 234,373 shares of common stock for issuance upon the vesting of RSUs. The Company has also reserved 11,492,280 shares of common stock for issuance upon conversion of the Convertible Notes, subject to adjustment in accordance with the Indenture. In January 2018, the Company completed an underwritten public offering of $450.0 million aggregate principal amount of Convertible Notes, including the exercise in full of the underwriter's option to purchase additional Convertible Notes. The fair value of the liability component of the Convertible Notes on the date of issuance was estimated at $309.1 million , and accordingly, the equity component (included in additional paid-in capital) on the date of issuance was calculated as $140.9 million using the residual method as further described in Note 5 Debt .

Share-based Compensation [Abstract] | |
Stock-Based Compensation | Stock-Based Compensation The Company’s current equity compensation plan, the 2017 Incentive Plan, was approved by shareholders at the Company’s Annual Meeting of Shareholders on May 18, 2017. The 2017 Incentive Plan is administered by the Compensation Committee and the Board of Directors of the Company. Under the terms of the 2017 Incentive Plan, the Company is authorized to grant a variety of incentive awards based on its common stock, including stock options (both incentive stock options and non-qualified stock options), RSUs, performance options/shares and other stock awards, as well as pay incentive bonuses to eligible employees and non-employee directors. On May 18, 2017, upon the approval of the 2017 Incentive Plan by shareholders, 5,000,000 shares were authorized for issuance thereunder, plus any shares subject to then-outstanding awards under the 2015 Incentive Plan and the 2013 Incentive Plan that subsequently were canceled, terminated unearned, expired, were forfeited, lapsed for any reason or were settled in cash without the delivery of shares. As of March 31, 2018 , 3,643,015 shares remained for future issuance under the 2017 Incentive Plan. The 2017 Incentive Plan will terminate on April 3, 2027 unless it is extended or terminated earlier pursuant to its terms. In addition, from time to time, the Company makes inducement grants of stock options. These awards are made pursuant to the NASDAQ inducement grant exception as a component of new hires’ employment compensation in connection with the Company’s equity grant program. During the three months ended March 31, 2018 , the Company granted inducement stock options covering 236,730 shares of the Company's common stock to new employees. Stock Options - The Company calculates the fair value of stock options granted using the Black-Scholes valuation model. The following table summarizes the Company’s grant date fair value and assumptions used in determining the fair value of all stock options granted during the periods presented: Three Months Ended March 31, 2018 2017 Volatility 67%-68% 73%-74% Risk-free interest rate 2.25%-2.65% 1.86%-1.99% Dividend yield 0.0% 0.0% Expected option term (in years) 5.08 6.25 Weighted average fair value of stock options granted $17.07 $9.18 For each period presented, the volatility factor was based on the Company’s historical volatility during the expected option term. Estimated forfeitures are based on the actual percentage of option forfeitures since the closing of the Company’s merger with Transave, Inc. in December 2010. The expected option term for these grants was determined using the Company’s historical exercise behavior. From time to time, the Company grants performance-condition options to certain of its employees. Vesting of these options is subject to the Company achieving certain performance criteria established at the date of grant and the grantees fulfilling a service condition (continued employment). As of March 31, 2018 , the Company had performance options totaling 133,334 shares outstanding which had not yet met the recognition criteria. The following table summarizes the Company’s aggregate stock option activity for the three months ended March 31, 2018 : Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Life in Years Aggregate Intrinsic Value (in thousands) Options outstanding at December 31, 2017 8,608,921 $ 14.08 Granted 1,322,350 $ 29.51 Exercised (12,628 ) $ 11.23 Forfeited or expired (53,069 ) $ 15.70 Options outstanding at March 31, 2018 9,865,574 $ 16.14 7.49 $ 73,003 Vested and expected to vest at March 31, 2018 9,499,525 $ 15.97 7.44 $ 71,286 Exercisable at March 31, 2018 4,679,778 $ 12.97 6.17 $ 44,855 The total intrinsic value of stock options exercised during the three months ended March 31, 2018 and 2017 was $0.2 million and $0.5 million , respectively. As of March 31, 2018 , there was $44.7 million of unrecognized compensation expense related to unvested stock options which is expected to be recognized over a weighted average period of 2.73 years. Included in unrecognized compensation expense was $1.1 million related to outstanding performance-condition options. These performance-condition options will vest, and compensation expense will be recognized, in the period when FDA approval of ALIS is received in the US. The following table summarizes the range of exercise prices and the number of stock options outstanding and exercisable as of March 31, 2018: Outstanding as of March 31, 2018 Exercisable as of March 31, 2018 Range of Exercise Prices ($) Number of Options Weighted Average Remaining Contractual Term (in years) Weighted Average Exercise Price ($) Number of Options Weighted Average Exercise Price ($) $ 3.03 $ 6.90 1,107,302 4.48 $ 4.01 1,069,802 $ 3.91 $ 6.96 $ 10.85 1,068,246 8.01 $ 10.76 419,017 $ 10.62 $ 11.14 $ 12.58 1,085,440 6.12 $ 12.17 799,415 $ 12.17 $ 12.66 $ 13.67 1,031,771 8.46 $ 13.59 329,907 $ 13.53 $ 13.94 $ 16.07 1,191,255 7.24 $ 15.28 666,341 $ 15.12 $ 16.09 $ 17.16 1,489,378 8.47 $ 16.70 350,612 $ 16.18 $ 17.24 $ 22.76 1,436,957 6.77 $ 21.11 1,009,373 $ 21.07 $ 22.84 $ 30.46 1,279,095 9.66 $ 29.05 35,311 $ 23.80 $ 30.86 $ 31.78 155,960 9.74 $ 31.10 — $ — $ 32.46 $ 32.46 20,170 9.76 $ 32.46 — $ — Restricted Stock and Restricted Stock Units — The Company may grant restricted stock (RS) and RSUs to eligible employees, including its executives, and non-employee directors. Each share of RS vests, and each RSU represents a right to receive one share of the Company’s common stock, upon the completion of a specific period of continued service or achievement of a certain milestone. RS and RSU awards are valued at the market price of the Company’s common stock on the date of grant. The Company recognizes noncash compensation expense for the fair values of these RS and RSU awards on a straight-line basis over the requisite service period of these awards.

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes The Company’s provision for income taxes was $48,000 and $30,000 for the three months ended March 31, 2018 and 2017 , respectively. The provision for income taxes in all periods was a result of certain of the Company’s subsidiaries in Europe, which had taxable income during the three months ended March 31, 2018 and 2017 . In jurisdictions where the Company has net losses, there was a full valuation allowance recorded against the Company’s deferred tax assets and therefore no tax benefit was recorded. The Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. The Company recorded a provisional amount of $94.0 million as of December 31, 2017 related to the remeasurement of certain deferred tax balances, offset by the write-down of the full valuation allowance recorded. Upon further analyses of certain aspects of the Tax Cut and Jobs Act and refinement of the Company's calculations during the three months ended March 31, 2018, the Company determined that the provisional amount would not need to be adjusted. The Company is subject to US federal, US state and foreign income taxes. In regards to foreign income taxes, the Company was subject to a one-time transition tax based on its total earnings and profits, which are generally deferred from US income taxes under previous US law. Due to the aggregate loss position of our foreign subsidiaries, the Company did not record any provisional amount for the one-time transition tax liability at December 31, 2017. The Company is subject to US federal and state income taxes and the statute of limitations for tax audit is open for the federal tax returns for the years ended 2014 and later, and is generally open for certain states for the years 2013 and later. The Company has incurred net operating losses since inception, except for the year ended December 31, 2009. Such loss carryforwards would be subject to audit in any tax year in which those losses are utilized, notwithstanding the year of origin. As of March 31, 2018 and December 31, 2017 , the Company had recorded no reserves for unrecognized income tax benefits, nor had it recorded any accrued interest or penalties related to uncertain tax positions. The Company does not anticipate any material changes in the amount of unrecognized tax positions over the next 12 months. |

Commitments and Contingencies | Commitments and Contingencies The Company has an operating lease for office and laboratory space located in Bridgewater, NJ, its corporate headquarters, for which the initial lease term expires in November 2019. Future minimum rental payments under this lease are $1.7 million . In July 2016, the Company signed an operating lease for additional laboratory space located in Bridgewater, NJ for which the initial lease term expires in December 2021. Future minimum rental payments under this lease are $1.8 million . Rent expense charged to operations was $0.4 million and $0.4 million for the three months ended March 31, 2018 and 2017 , respectively. Future minimum rental payments required under the Company’s operating leases for the period from April 1, 2018 to December 31, 2018 and for each of the five years thereafter are as follows (in thousands): Year Ending December 31: 2018 (remaining) $ 1,145 2019 1,421 2020 477 2021 498 2022 — 2023 — $ 3,541 Legal Proceedings On July 15, 2016, a lawsuit captioned Hoey v. Insmed Incorporated, et al, No. 3:16-cv-04323-FLW-TJB (D.N.J. July 15, 2016) was filed in the US District Court for the District of New Jersey on behalf of a putative class of investors who purchased the Company’s common stock from March 18, 2013 through June 8, 2016. The complaint alleged that the Company and certain of its executives violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (Exchange Act) by misrepresenting and/or omitting the likelihood of the European Medicines Agency (EMA) approving the Company’s European marketing authorization application (MAA) for use of ALIS in the treatment of NTM lung disease and the likelihood of commercialization of ALIS in Europe. On October 25, 2016, the Court issued an order appointing Bucks County Employees Retirement Fund as lead plaintiff for the putative class. On December 15, 2016, the lead plaintiff filed an amended complaint that shortened the putative class period for the Exchange Act claims to March 26, 2014 through June 8, 2016 and added claims under Sections 11, 12, and 15 of the Securities Act of 1933 (Securities Act) on behalf of a putative class of investors who purchased common stock in or traceable to the Company’s March 31, 2015 public offering. The amended complaint named as defendants in the Securities Act claims the Company, certain directors and officers, and the investment banks who served as underwriters in connection with the secondary offering. The amended complaint alleged defendants violated the Securities Act by using a purportedly misleading definition of “culture conversion” and supposedly failing to disclose in the offering materials purported flaws in its Phase 2 study that made the secondary offering risky or speculative and sought damages in an unspecified amount. The Company moved to dismiss the amended complaint on March 1, 2017. On February 15, 2018, the Court issued a decision granting the motion and dismissing the amended complaint without prejudice as to all defendants. On March 22, 2018 after the lead plaintiffs failed to file an amended complaint, the Court entered final judgment in favor of the defendants, and dismissed the case with prejudice. The deadline for appeal has now passed and the Company considers the case closed. From time to time, the Company is a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. While the outcomes of these matters are uncertain, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. |

Accounting Policies [Abstract] | |
Fair Value Measurements | Fair Value Measurements - The Company categorizes its financial assets and liabilities measured and reported at fair value in the financial statements on a recurring basis based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs used to determine the fair value of financial assets and liabilities, are as follows: • Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the assets or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Each major category of financial assets and liabilities measured at fair value on a recurring basis is categorized based upon the lowest level of significant input to the valuations. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments in Level 1 generally include US treasuries and mutual funds listed in active markets. The Company’s only financial assets and liabilities which were measured at fair value as of March 31, 2018 and December 31, 2017 were Level 1 and such assets were comprised of cash and cash equivalents of $686.6 million and $381.2 million , respectively. The Company’s cash and cash equivalents permit daily redemption and the fair values of these investments are based upon the quoted prices in active markets provided by the holding financial institutions. Cash equivalents consist of liquid investments with an original maturity of three months or less from the date of purchase. As of March 31, 2018 , the Company's cash and cash equivalents balance included US treasury bills of $180.0 million . The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers in or out of Level 1, Level 2 or Level 3 during the three months ended March 31, 2018 and 2017 , respectively. As of March 31, 2018 and December 31, 2017 , the Company held no securities that were in an unrealized gain or loss position. The Company reviews the status of each security quarterly to determine whether an other-than-temporary impairment has occurred. In making its determination, the Company considers a number of factors, including: (1) the significance of the decline; (2) whether the securities were rated below investment grade; (3) how long the securities have been in an unrealized loss position; and (4) the Company’s ability and intent to retain the investment for a sufficient period of time for it to recover. |
Net Loss Per Share | Net Loss Per Share - Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares and other dilutive securities outstanding during the period. Potentially dilutive securities from stock options, restricted stock units (RSUs) and convertible debt securities would be anti-dilutive as the Company incurred a net loss. Potentially dilutive common shares resulting from the assumed exercise of outstanding stock options are determined based on the treasury stock method. The following table sets forth the reconciliation of the weighted average number of common shares used to compute basic and diluted net loss per share for the three months ended March 31, 2018 and 2017 : Three Months Ended March 31, 2018 2017 (in thousands, except per share amounts) Numerator: Net loss $ (68,524 ) $ (37,414 ) Denominator: Weighted average common shares used in calculation of basic net loss per share: 76,619 62,041 Effect of dilutive securities: Common stock options — — RSUs — — Convertible debt securities — — Weighted average common shares outstanding used in calculation of diluted net loss per share 76,619 62,041 Net loss per share: Basic and Diluted $ (0.89 ) $ (0.60 ) The following potentially dilutive securities have been excluded from the computations of diluted weighted average common shares outstanding as of March 31, 2018 and 2017 as their effect would have been anti-dilutive (in thousands): As of March 31, 2018 2017 Stock options to purchase common stock 9,866 7,719 Unvested RSUs 234 89 Convertible debt securities 11,492 — |
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements - In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which addressed eight specific cash flow issues with the objective of reducing the existing diversity in practice. Among the updates, the standard requires debt extinguishment costs to be classified as cash outflows for financing activities. This standard update is effective as of the first quarter of 2018. As a result of the adoption of the standard, in the first quarter of 2018, the Company reported a $2.2 million loss on extinguishment of debt in the financing activities section of its consolidated statement of cash flows. The Company had no material debt extinguishment costs prior to the first quarter of 2018. There were no other significant impacts as a result of adopting this standard. In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , which defines management’s responsibility to perform interim and annual assessments of an entity’s ability to continue as a going concern, and to provide related footnote disclosures if there is substantial doubt about its ability to continue as a going concern. The new standard was effective for the annual period ending after December 15, 2016, and for interim periods thereafter. The Company adopted ASU 2014-15 in the fourth quarter of 2016, which had no impact on the Company’s consolidated financial statements. The interim assessment during the first quarter of 2018 did not have an impact on the consolidated financial statements. The Company had $686.6 million in cash and cash equivalents as of March 31, 2018 and reported a net loss of $68.5 million for the three months ended March 31, 2018 . Historically, the Company has funded its operations through public offerings of equity securities and debt financings. To date, the Company has not generated material revenue from ALIS. The Company does not expect to generate material revenue unless or until marketing approval is received for ALIS. Accordingly, the Company expects to continue to incur losses while funding research and development (R&D) activities, regulatory submissions, potential commercial launch activities and general and administrative expenses. The Company expects its future cash requirements to be substantial, and the Company may need to raise additional capital to fund operations, to develop and commercialize ALIS, to develop INS1007 and INS1009 and to develop, acquire, in-license or co-promote other products that address orphan or rare diseases. ASU 2014-15 requires the Company to evaluate whether it has sufficient resources to fund operations for 12 months from the filing date of this Quarterly Report on Form 10-Q without regard to whether or not it can raise capital in the future. The Company believes it currently has sufficient funds to meet its financial needs for at least the next 12 months. In September 2017, the Company completed an underwritten offering of 14.1 million shares of its common stock for cash proceeds of $377.7 million , net of fees and expenses related to the offering. Further, in January 2018, the Company completed an underwritten public offering of 1.75% convertible senior notes due 2025 (the Convertible Notes) pursuant to an indenture, dated as of January 26, 2018, between the Company and Wells Fargo Bank, National Association (Wells Fargo), as trustee, as supplemented by the first supplemental indenture, dated January 26, 2018, between the Company and Wells Fargo (as supplemented, the Indenture). The Company sold $450.0 million aggregate principal amount of Convertible Notes, including the exercise in full of the underwriters' option to purchase additional Convertible Notes of $50.0 million . The Company's net proceeds from the offering, after deducting underwriting discounts and commissions and other offering expenses of $14.1 million , were approximately $435.9 million . The source, timing and availability of any future financing or other transaction will depend principally upon continued progress in the Company’s regulatory, development and pre-commercial activities. Any equity or debt financing will also be contingent upon equity and debt market conditions and interest rates at the time. If the Company is unable to obtain sufficient additional funds when required, the Company may be forced to delay, restrict or eliminate all or a portion of its R&D programs, pre-commercialization activities, or dispose of assets or technology. In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers (Topic 606) which amended the existing accounting standards for revenue recognition. ASU 2014-9 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. In July 2015, the FASB deferred the effective date for annual reporting periods beginning after December 15, 2017. The Company adopted ASU 2014-9 in the first quarter of 2018 and the impact of adoption is not material to its consolidated financial statements. New Accounting Pronouncements (Not Yet Adopted) —In February 2016, the FASB issued ASU 2016-2, Leases (Topic 842) in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. ASU 2016-2 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the balance sheet. ASU 2016-2 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. The Company expects to adopt ASU 2016-2 in the first quarter of 2019 and is in the process of evaluating the impact of adoption on its consolidated financial statements. |
